Adjustable PTFE Expansion Joint Bellows Carbon Steel Tie Rod
PTFE expansion joint (also known as expansion joint) is used to
compensate the displacement and installation deviation of thermal
expansion and cold contraction in strong corrosive medium pipeline
system, so as to reduce the vibration of pipeline system. PTFE
expansion joint is usually used in the chemical field of pipeline.
The PTFE expansion joint is wrapped with a new sealing material
flexible graphite ring, which has the characteristics of high
strength, low friction coefficient (0.04 ~ 0.10), no aging, good
effect and convenient maintenance.

Applications of PTFE expansion joint
PTFE expansion joints can be used to eliminate the expansion or
displacement of pipes, containers or equipment due to climate
change or other reasons. The PTFE expansion joint can also be
installed at the inlet and outlet of the pump or at both ends of
other high-frequency machinery to reduce or eliminate its
vibration. The PTFE expansion joint can improve the service life
and sealing performance of the pipeline. PTFE expansion joint is
the compensation device of hot fluid pipeline, which is mainly used
for the auxiliary equipment of linear pipeline. The PTFE expansion
joint is suitable for hot water, steam, grease and other media. The
sliding motion of the sliding sleeve can achieve thermal
compensation.
