This section provides an overview for flame retardant tubing as well as their applications and principles. Also, please take a look at the list of 9 flame retardant tubing manufacturers and their company rankings.
Flame retardant tubing is tubing made of a flame retardant polymer, which is resistant to ignition and deformation due to heat. Air and water can be pumped through the tubes, and depending on the product, electrical cables can also be passed through. In addition to being used in high-temperature environments such as welding, they are also used to increase the fire resistance of buildings and as a protective material to protect electrical cables from high temperatures.
The higher the temperature, the lower the pressure resistance tends to be. Check the relationship between temperature and pressure resistance in the specifications sheet, and be careful not to apply excessive pressure.
There is always a risk of ignition of combustible materials in places where fire is handled, where there are heating elements such as hot plates, or where electrical sparks are generated. In the unlikely event of ignition, if flammable materials such as vinyl or polyethylene are nearby, the fire will spread further. For this reason, tubing for water and air delivery must be made of flame retardant materials at sites where fire, heating elements, or high-voltage electrical currents are handled.
For example, flame retardant tubing is used to supply air and gas to welding equipment and burners.
General tubing is made of polyethylene or vinyl chloride resin, which has a low-heat resistance and can deform or melt in high-temperature situations. Furthermore, once ignited, they can become fuel and spread a fire.
Flame retardant tubing, on the other hand, is made of flame retardant elastomers, which are less likely to catch fire, and even if it does catch fire, it will be extinguished spontaneously without spreading. Flame retardant tubing prevents ignition in the event of a spark. In addition, because it does not become fuel in the event of a fire, it is also used in gas stations, lodging facilities, ships, and so on.
However, just because it does not ignite easily does not mean that it can be used at high temperatures for long periods of time. Although it depends on the product, the upper limit for the temperature of air or liquid in constant contact is around 212°F. If air or liquid is allowed to flow into the tube at higher temperatures, it will cause deformation and deterioration. The higher the temperature, the lower the pressure resistance tends to be. Therefore, the heat resistance must always be checked in the specifications, and air and liquid must be pumped at safe temperatures and pressures.
