Product Introduction
PTFE lining is made of a layer of PTFE lining in the rubber joint,
PTFE which can resist strong acid and alkali. It can be used in
chemical industry and sewage transportation. The rubber joint has
the characteristics of high pressure resistance, good elastic
strength, large compensation displacement, pipeline deviation of
balanced transportation system, vibration transmission between
absorption pipelines, good noise reduction effect, convenient
installation, etc.
Advantages of PTFE lined rubber expansion joints
1. PTFE rubber expansion joint is lined with high pressure, high
temperature and oil resistance.
2. PTFE lined rubber expansion joint is wear-resistant, corrosion
resistant, acid and alkali resistant.
3. Connect with pumps, valves, fire-fighting equipment, pipes with
large vibration, and pipes with frequent changes in cold and heat.
4. Long service life
5. Reduce vibration and noise
Product Applications
1. Petrochemical industry
2. Pharmaceutical and food processing industries
3. Aviation, aerospace, electronic and electrical industries
4. Construction industry

Installation instructions
1.Rubber soft joints in installation is strictly prohibited over
displacement limit installation.
2.Flat,suspended,vertical installation of rubber joints,supporting
force of pipeline working pressure less than the axial displacement
of the rubber joint,you should install anti pull off device,to
prevent the work pressure.
3.The pipeline must have a fixed support or fixed bracket,the fixed
bracket force must be greater than the axial force.Vertical
installation and overhead installation products both ends need to
install the corresponding fixed bracket and force support,to
prevent the compression.
4.The installation bolts should be symmetrical,gradually tightened
to prevent partial leakage.
5.The installation should be away from the heat source,strictly
prohibit the use of products that do not meet the requirements of
the media.
