The use of non-metal expansion joints in smoke ducts
Henan Huitong is a company specializing in the production of expansion joints A professional manufacturing company, our company has been engaged in the production and research of expansion joints for more than 25 years. Due to different working conditions of smoke and air ducts, it is impossible to fix which type of expansion joint to install. So which type of expansion joint is most suitable for smoke and air ducts? What about the use of pipes?
The most commonly used expansion joints in smoke and air ducts are made of non-metallic materials, because non-metallic expansion joints can compensate for the axial and transverse angular displacement of the medium in the pipe due to temperature changes, and have no thrust force. , simplified support design, corrosion resistance, high temperature resistance, noise reduction and shock absorption, etc., and the price is much lower than that of metal expansion joints. Moreover, since the non-metal expansion joint is composed of one layer of silicone cloth and two layers of alkali-free glass fiber cloth It is composed of a layer of PTFE cloth. After the product has experienced environmental corrosion and reached the end of its service life, when the covering cloth will be damaged, there is no need to replace the non-metallic expansion joint as a whole. Simply remove the corroded covering cloth and reinstall the new one. It can work normally if it is fixed. It can also be seen from this point that the flue gas pipe uses non-metal
