Expansion Loop Pipe SS316 High Temperature Resistance PTFE Lined Bellows Metal
This SS316 metal bellows expansion loop pipe features a PTFE lining and excellent high-temperature resistance, integrating the structural strength of 316 stainless steel and the superior corrosion/chemical resistance of PTFE. The metal bellows design enables flexible axial, lateral and angular compensation, effectively absorbing pipe thermal expansion, contraction and vibration displacement, while the PTFE lining ensures safe media conveyance even in high-temperature, corrosive working conditions. It is widely applied in petrochemical, pharmaceutical, food processing and other industrial piping systems that require thermal compensation and corrosion resistance, with reliable sealing performance and long service life, effectively reducing pipe system stress and improving operational stability.
Performance of PTFE Lined Bellows Metal
The main elastic element of Ptfe Lined Metal expansion loop pipe is stainless steel bellows. Through the expansion and bending of bellows, the flexible expansion joint compensates the pipeline in axial, transverse and angular directions. Bellows expansion can play the following roles:
1. The Ptfe Lined Metal expansion loop pipeabsorbs the axial, transverse and angular thermal deformation of the pipeline.
2. Ptfe Lined Metal expansion loop pipe can absorb equipment vibration and reduce the influence of equipment vibration on pipeline.
3. Ptfe Lined Metal expansion loop pipe can absorb the pipeline deformation caused by earthquake and land subsidence.
