PTFE Lined Anti-Corrosive Flexible Metal Bellows/ Chemical PTFE Hose
Production Description
Production Description
The pipe has changed the characteristics that the pipe can not be bent by special processing methods. It can be used to connect the lower graphite and ceramic glass pipes, and can be used as the feeding and discharging pipe for tank trucks, tanks, containers or reaction still. It can be used for pipe misalignment or to balance pipe displacements, dimensional changes caused by climate or other reasons, or to eliminate high-frequency mechanical vibrations. Can also be used in special occasions such as tubular reactor or heat exchanger
