Chlorine dioxide (ClO2) is a chemical compound consisting of one chlorine atom and two oxygen atoms. It is a reddish to yellowish-green gas at room temperature that dissolves in water. It is used for a variety of antimicrobial uses, including the disinfection of drinking water. Chlorine dioxide gas is usually produced onsite from sodium chlorate or sodium chlorite.
Uses & Benefits
Powerful Disinfection in Water Treatment
Chlorine dioxide is a disinfectant. When added to drinking water, it helps destroy bacteria, viruses and some types of parasites that can make people sick, such as Cryptosporidium parvum and Giardia lamblia. The Environmental Protection Agency (EPA) regulates the maximum concentration of Chlorine Dioxide Tablets in drinking water to be no greater than 0.8 parts per million (ppm).
Industrial/Manufacturing Uses
Chlorine dioxide chemistry is used in a wide variety of industrial, oil and gas, food and municipal applications:
Safety Information
Chlorine Dioxide Liquid is used to disinfect drinking water around the world. According to U.S. Centers for Disease Control and Prevention, chlorine dioxide is added to drinking water to protect people from harmful bacteria and other microorganisms. EPA recognizes chlorine dioxide use as a drinking water disinfectant, and it is included in the World Health Organization’s (WHO) Guidelines for Drinking-water Quality.
In its pure form, chlorine dioxide is a hazardous gas but most people are “not likely” to breathe air containing dangerous levels of chlorine dioxide as it rapidly breaks down in air to chlorine gas and oxygen. For workers who use chlorine dioxide, the U.S. Occupational Safety and Hazard Administration (OSHA) regulates the level of chlorine dioxide in workplace air for safety. OSHA has set a Permissible Exposure Limit (PEL) for chlorine dioxide at 0.1 parts per million (ppm), or 0.3 milligrams (mg) per cubic meters (m3) for workers using chlorine dioxide for general industrial purposes. OSHA also has a PEL for chlorine dioxide for the construction industry.
Air Disinfection Gel is one powerhouse sanitizer that is getting more attention recently as food processors look for more efficacious products to help them win the sanitation battle. Approved by the U.S. Food and Drug Administration (FDA) and the U.S. Environmental Protection Agency (EPA), it is as powerful as peracetic acid and more economical, yet it has far less of an impact on the environment than quaternary ammonium salts, chlorine or bromine, making it an excellent choice for food processing plants. It costs about the same to use as other sanitizers but is more versatile and less harmful. It’s also been shown to destroy and prevent biofilms, one of the biggest challenges to food processors in destroying harmful bacteria. It also does not have the strong odor or corrosive qualities associated with chlorine. It is a versatile alternative that can be used in many sanitation applications, including pasteurization equipment, heat exchangers, cooling towers, hard surface disinfecting, potable water treatment and deodorizing stacks in rendering plants. It is already growing in popularity as a tool to control microbiological growth in the dairy industry, the beverage industry, the fruit and vegetable processing industries, canning plants, and in poultry and beef facilities.
Sodium Dichloroisocyanurate is the sodium salt of a chlorinated hydroxytriazine and is used as a source of free available chlorine, in the form of hypochlorous acid, for the disinfection of water. It is widely used as a stable source of chlorine for the disinfection of swimming pools and in the food industry. It is also used as a means of disinfecting drinking-water, primarily in emergencies, when it provides an easy-to-use source of free chlorine, and, more recently, as the form of chlorine for household point-of-use water treatment.
Disinfectant Wipes should never be reused. Reusing wipes will move germs from one surface to another, which is potentially harmful in the current pandemic. In order for any surface to be properly disinfected, the U.S. CDC recommends following the instructions on each product carefully and leaving the disinfectant on the surface for 3-5 minutes. This means the surface needs to be wet for this period of time, and you may need to use more than one disinfectant wipe depending on the size of the surface. However, you should never reuse the same disinfectant wipe.

Airless spray application shall be in accordance with the following procedure:
as per steel structure paint Manual Vol.1 & Vol.2 by SSPC, USA, Air less spray relies on hydraulic pressure rather than air atomization to produce the desired spray. An air compressor or electric motor is used to operate a pump to produce pressures of 1000 to 6000 psi.
Paint is delivered to the spray gun at this pressure through a single hose within the gun. A single paint stream is divided into separate streams, which are forced through a small orifice resulting in atomization of paint without the use of air. This results in more rapid coverage with less over spray.
Airless spray usually is faster, cleaner, more economical and easier to use than conventional air spray.
Pipe Spray Painting Machine is mounted on wheels, and paint is aspirated in a hose that sucks paint from any container, including drums. The unit shall have inbuilt agitator that keep the paint uniformly mixed during the spraying. The unit shall consist of inbuilt strainer. Usually very small quantities of thinning are required before spray. In case of High Build Epoxy coating (two pack). 30:1 pump ratio and 0.020-0.023” tip size will provide a good spray pattern. Ideally fluid hoses should not be less than 3/8” ID and not longer than 50 ft to obtain optimum results. In case of gun choking, de-choking steps shall be followed immediately.
What Are Spray Painting and Powder Coating?
Spray Steel Pipe Painting Production Line is the process of applying liquid paint using pressure. This can be done in one of three ways:
Conventional High-Pressure Spray Painting
This method uses an air compressor and an air gun. When the gun's trigger is pressed, the paint mixes with the compressed air stream and a fine spray is released from the nozzle.
The air gun is usually held about 6 to 10 inches from the object being painted and moved back and forth over the surface to ensure an even and continuous coat.
Airless Spraying Systems
These Steel Pipe Spraying Coating Machine systems use a high-pressure pump, which can range in pressure from just 300 to 7,500 pounds per square inch, depending on the application.
Laser marking works by using a focused beam of light to mark the surface of a material. When the beam interacts with the material’s surface, it alters the material’s properties and appearance. This concentrated beam targets only a specified area, allowing the laser Automatic Marking Machine to create precise, high quality, high-contrast marks that are easy to read or scan on virtually any surface. This feature makes laser marking ideal for applications where accuracy and permanency are critical to success.
There are several types of laser marking systems, and each operates slightly differently. The correct process to use the machine also depends on the material you’re working with and the application you’re using. MECCO offers a list of resources to help you operate your machine and troubleshoot any issues, from how-to videos to detailed documentation. When using any laser marking machine, it’s important to follow all safety guidelines. Thanks to a variety of preventative measures, including safety enclosure options, laser marking is a relatively safe process.

Sprocket Transfers are material handling systems that allow for easy transporting of products, from powder to bulk to complicated geometries. They are integral to all kinds of systems, as they provide a fast and safe method of handling large volumes of materials. There are many kinds of conveyors, but their working principle remains constant across each type; move objects via gravity or by mechanical power from one destination to the next by using a frame that holds belts, buckets, rollers, or other moving components. The roller conveyor, or conveyor roller, is the focus of this article and is one of the most popular conveyor varieties employed. The types, designs, and uses of roller conveyors will be explored, as well as how to specify one of these systems for any application.

Lapping Machines are a type of precision finishing machine. Lapping is a loose abrasive machining process that differs from honing or grinding because the abrasive action comes not from a solid abrasive (like a grinding wheel) but from a slurry--abrasive particles mixed with oil or water. The slurry forms an abrasive film between the underlying lapping plate and the parts to be lapped. The part stock is gradually removed through the rolling and sliding action of the abrasive grains between the lapping wheel and the workpiece. The slurry, along with the removed stock, drains away from the table.
Lapping machines create truly flat surfaces--normally up to 0.001mm, with surface finishes of better than Ra.01. Overall, lapping produces extreme dimensional accuracy, corrects minor imperfections of shape, refines surface finish, and produces close fit between mating surfaces.
Lapping machines may be beneficial whenever absolute flatness, parallelism, or surface finish is essential. Since it is a loose abrasive process, irregularly-shaped or non-magnetic parts can be easily accommodated. Lapping removes stock quickly, with no clamping or heat distortion, no expensive tooling required, and virtually no maintenance. Inspection and production costs are also lower, since the machine can be run by semi-skilled operators. Parts can be run as easily in small batches as in production processes.
How does it work?
Flat Lapping Machines consist of 5 parts: the rotating table (called a lapping plate), several conditioning rings, the topweight, the slurry, and the machine itself.
The machine houses the controls, engine, coolant, filter, and other subsidiary components for proper operation of the mechanism.
The lapping plate is the only thing that is turned by the motor--the conditioning rings turn automatically as the plate itself turns. The plate is usually made of high-quality soft cast iron, though copper and other soft metals may also be used. It may be anywhere from 12 to 144 inches in diameter and feature spirals, cross-hatches, rings, or other shapes.
The conditioning rings function as the workholding device. These rings distribute the wear evenly across the lapping plate increasing its life, while also holding the workpiece in place. Special rings may be fitted for cylindrical or especially long pieces.
A top plate presses the pieces down in order to ensure abrasion occurs. These may be simple lids or mechanically operated piston-like covers.
A slurry made by combining various abrasive materials such as diamond or carbon with a liquid base like oil or water is fed between the lapping plate and the top plate, and distributed evenly across the surface by the plate's rotation. The tiny abrasives suspended in the liquid drag and tumble across the surface of the held pieces, grinding away at any micro-irregularities in the part's surface.
The Polishing Machine (also called the Buffing Machine) is used to polish soft metals including copper and brass as well as plastics such as perspex. The two ‘mops’ spin at high speed when the ‘on’ switch is pressed. If the material is carefully pressed against the mop and moved backwards and forwards it will be polished. The material must be filed to removed scratches and then wet and dry paper or emery cloth is used to further smooth the surfaces. Only then can it be polished on the buffing machine.
There are many types of involved equipment in the wire drawing machine industry, the common Wire Drawing Machine has a water tank type drawing machine, straight wiredrawing machine, the pulley type drawing machine, inverted vertical drawing machine, and so on. Drawing machine is mainly used in the processing of copper wire, stainless steel wire and other metal wire and cable materials, belonging to the important processing equipment in the cable manufacturing industry. Drawing: drawing process is the most important work segment for wire drawing machine. Different metal material, silk varieties and different requirements, will have different drawing process, the end of the article will detail the water tank draw machine and straight wire-drawing machine specific operation process; Wire: the take-up links work speed determines the whole drawing machinery production efficiency, is the most difficult control portion during the whole system. In the coiling part, the control technology are commonly used the synchronous control and tension control for realization of metal winding; Line: line of metal wire, for the whole wire drawing machine, the control has no high accuracy requirements, to the majority of wire drawing machine, the line operation is through the inverter to drive line frame to achieve, but there are also drawing mechanical parts of dual frequency conversion control, or even directly through the drawing wire tension wire link to drawing machine, to realize the free line.
Lapping is the removal of material to produce a smooth, flat, unpolished surface. Lapping processes are used to produce dimensionally accurate specimens to high tolerances (generally less than 2.5 µm uniformity). The lapping plate will rotate at a low speed (<80 rpm) and a mid-range abrasive particle (5-20µm) is typically used. Lapping Disc removes subsurface damage caused by sawing or grinding and produces the required thickness and flatness. Although the lapping process is less damaging than grinding, there are two regimes of lapping: free abrasive lapping and fixed abrasive lapping. Free Abrasive Lapping is when abrasive slurry is applied directly to a lapping plate (e.g. cast iron). This is perhaps the most accurate method for producing specimens and causes the least amount of damage. Free abrasive lapping is accurate because of the rigid lapping surface which can be tailored to suit a particular material. Fixed Abrasive Lapping is when an abrasive particle in bonded to a substrate as with abrasive lapping films and SiC papers. Abrasive lapping films have various particles bonded to a thin, uniform polyester substrate and are also capable of producing a very flat surface. SiC papers are much thicker than the film and create the potential for rounded edges on the sample. With the continuous development of inverter technology, frequency converter has been widely used in the industry of wire drawing machine, bear the drawing speed, tension coiler, multistage synchronous control etc, the application of frequency converter, have greatly improved the automation level and processing ability, effectively reduces the energy consumption per unit of equipment and maintenance costs, widely recognized by the industry.
Sanding sponges are sponge-like sanding tools used for sanding wood, drywall, and plastic. Sanding sponges are like sandpaper, but the abrasive material is attached directly to the foam of the sponge instead of a piece of paper.
What’s a Sanding Sponge?
Sponge Sands have been around for some time. We’ve all sanded with the traditional sheet of sandpaper. Sometimes, our hands get tired trying to apply the proper pressure to the paper.
This lead people to use something called a sanding block. Basically, the sanding block is used as a base, and the sandpaper is secured around the block, giving you an even pressure.
The sanding sponge is a combination between the sanding block and sandpaper. However, the two are not entirely interchangeable, as I will explain in later sections.

What is a Level Switch?
A Level Switch is an electrical or mechanical method for measuring the level of a liquid, powder, or granule material. It is designed to activate an alarm if the material level in a container passes a predetermined height or depth. When a level switch detects that a tank is full, it is referred to as full or upper limit detection. If the level of the material drops, indicating that the tank is nearly empty, the switch will also provide an alert, which is referred to as empty or low level detection.
Level switches are an essential part of production operations and are used in harsh conditions where there are extremes in temperature, pressure, and vibrations. The diversity of level switches makes them applicable to any conditions for measuring a wide array of products. Their accuracy, reliability, and durability are a necessity for the efficiency of industrial applications.
What is a Liquid Level Gauge?
A liquid Level Gauge, also known as a level indicator or sight glass, is a meter that is used to determine liquid level in a process tank, vessel or drum. A level gauge is simply a glass tube that gives a visual representation of the level of liquid that is in the vessel. While simple in their design, they are a very effective technology for a direct visual indication of process fluid level. There are many applications across the industry that require the monitoring of the liquid level and there are many different types of level indicators to fulfill these varying needs. In many situations the fluid is dangerous or the place in which the liquid is stored is of such a nature that it is manually impossible to find the level, making some sort of level indicator imperative.
Liquid Level Transmitters are used to monitor and regulate levels of a particular free-flowing substance within a contained space. These substances are usually liquid, however liquid level sensors can also be used to monitor solids, such as powders. There are many different types of liquid level sensors, and they have several uses, both industrial and in the household for example.
Liquid level sensors are widely used industrially. Cars use liquid level sensors to monitor a variety of liquids, including fuel, oil and occasionally also specialist fluids such as power steering fluid. Liquid level sensors can also be found in industrial storage tanks, for slurries, and water level sensors can even be found in household appliances such as coffee machines. Basic liquid level sensors can be used to identify the point at which a liquid falls below a minimum or rises above a maximum level. Many liquid level sensors can detail the specific amount of liquid in a container relative to the minimum/maximum levels, to provide a continuous measurement of volume.
A Flow Meter (or flow sensor) is an instrument used to measure linear, nonlinear, mass or volumetric flow rate of a liquid or a gas. When choosing flowmeters, one should consider such intangible factors as familiarity of plant personnel, their experience with calibration and maintenance, spare parts availability, and mean time between failure history, etc., at the particular plant site. It is also recommended that the cost of the installation be computed only after taking these steps. One of the most common flow measurement mistakes is the reversal of this sequence: instead of selecting a sensor which will perform properly, an attempt is made to justify the use of a device because it is less expensive. Those "inexpensive" purchases can be the most costly installations. This page will help you better understand flow meters, but you can also speak to our application engineers at anytime if you have any special flow measurement challenges.
When left unmonitored, several of the gases emitted in research and industry can pose significant explosion, asphyxiation, or poisoning risks. The first line of defense against these invisible threats are Gas Detectors, but it can be challenging to understand which type of detector to employ for a specific application.
A wide range of gas detection hardware is available on the market, from portable single-gas detectors to fixed sensor arrays that can precisely monitor huge quantities of different gases at the same time (known as multi-gas or multi-component detectors).
Gas hazards can be generally categorized as either toxic, combustible, or asphyxiating (where the body is deprived of oxygen). Researching the possible gas hazards in a specific application is an integral part of ensuring the safety of personnel in wastewater treatment plants, petrochemical processing facilities, and a range of additional industries. After specific gas hazards have been determined in a particular environment and all potential measures have been put in place to reduce the risk of dangerous gas accumulation or gas leaks, companies must remain vigilant.
Both fixed and portable gas detectors are important life-saving devices that should be correctly used in any environment that may pose a gas risk.
A Pressure Transmitter is a mechanical device that measures the expansive force of a liquid or gaseous sample.
Also known as a pressure transducer, this type of sensor is typically composed of a pressure sensitive surface area made of steel, silicon, or other materials depending upon the analyte’s composition. Behind these surfaces are electronic components capable of converting the applied force of the sample upon the pressure sensor into an electrical signal.
Pressure is generally measured as a quantity of force per unit of surface area, and is expressed as the value required to stop a liquid, gas, or vapor from expanding. Various derived units are used to quantify pressure, including:
A Flow Switch, like all switches, is a device designed to make and break an electric current in a circuit. In an industrial system, a flow switch is essential in monitoring and controlling the flow rate of process media – such as steam, liquids, and gases. Flow switches help maintain safe and manageable rates of flow by triggering actions in various machines within a system to provide on/off flow control of process media. As previously stated, flow switches are used to monitor and control the flow rate of fluid within an industrial process system. Automated industrial systems that process fluid media rely heavily on flow switches to ensure safe and optimal flow rates. Flow switches respond to pre-set flow rate levels and perform two functions when those levels are reached: namely, closing its contacts and turning a specific piece of equipment ON, or opening its contacts and turning a specific piece of equipment OFF.
A Level Switch is an electrical or mechanical method for measuring the level of a liquid, powder, or granule material. It is designed to activate an alarm if the material level in a container passes a predetermined height or depth. When a level switch detects that a tank is full, it is referred to as full or upper limit detection. If the level of the material drops, indicating that the tank is nearly empty, the switch will also provide an alert, which is referred to as empty or low level detection.
Level switches are an essential part of production operations and are used in harsh conditions where there are extremes in temperature, pressure, and vibrations. The diversity of level switches makes them applicable to any conditions for measuring a wide array of products. Their accuracy, reliability, and durability are a necessity for the efficiency of industrial applications.
What is a Liquid Level Gauge?
A liquid Level Gauge, also known as a level indicator or sight glass, is a meter that is used to determine liquid level in a process tank, vessel or drum. A level gauge is simply a glass tube that gives a visual representation of the level of liquid that is in the vessel. While simple in their design, they are a very effective technology for a direct visual indication of process fluid level. There are many applications across the industry that require the monitoring of the liquid level and there are many different types of level indicators to fulfill these varying needs. In many situations the fluid is dangerous or the place in which the liquid is stored is of such a nature that it is manually impossible to find the level, making some sort of level indicator imperative.
Liquid Level Transmitters are used to monitor and regulate levels of a particular free-flowing substance within a contained space. These substances are usually liquid, however liquid level sensors can also be used to monitor solids, such as powders. There are many different types of liquid level sensors, and they have several uses, both industrial and in the household for example.
Liquid level sensors are widely used industrially. Cars use liquid level sensors to monitor a variety of liquids, including fuel, oil and occasionally also specialist fluids such as power steering fluid. Liquid level sensors can also be found in industrial storage tanks, for slurries, and water level sensors can even be found in household appliances such as coffee machines. Basic liquid level sensors can be used to identify the point at which a liquid falls below a minimum or rises above a maximum level. Many liquid level sensors can detail the specific amount of liquid in a container relative to the minimum/maximum levels, to provide a continuous measurement of volume.

- A value of pounds per square inch (psi).
