Product performance:

Bellows raw materials are made of stainless steel 06Cr19Ni10 (SUS304) material, after the ribled corrugated forming and high temperature vacuum annealing (solid treatment), it effectively removes internal stress and enhances the bending and distortion resistance of bellows. The connection nut is made of national standard Hpb59-1 material, and after annealing surface chrome plating, the pipe is covered with flame retardant PVC protective cover, making the product equipped with high toughness, strong corrosion resistance, and do not rust after salt spray test, bending more than 30 times for pressure resistance and air tightness test with no leakage according to the standard requirements. The sealing ring is equipped with high temperature and low temperature resistant EPDM material, which can withstand the working temperature of-20℃ ~80℃ for a long time. Two sealing tests were conducted during the production process to ensure the sealing safety of the product after the factory. This gas corrugated hose is suitable for the gas system with an optional length, and there is no interface in the middle of the pipe body, reducing the connection point which eliminates the gas leakage. The use of buried wall, dark compress, open installation and other installation methods to meet the personalized needs of users. It is compensatory to avoid gas leakage caused by earthquake, building precipitation and seasonal change of natural gas and animal damage. Products ensure a safe service life of more than 50 years.
