1. Name:

PTFE bellows, F4 bellows, PTFE bellows, PTFE bellows, Teflon bellows, Teflon bellows, Teflon bellows, Teflon bellows, Teflon bellows, Teflon corrugated pipe, plastic king corrugated pipe

2. Color:

Common color: milky white tube

Unusual colors: yellow, brown, green, blue, red

3. Purpose

Can be used as tubular reactor and exchanger in special occasions

Can be used as feeding and discharging pipes for tank trucks, storage tanks, containers and reactors

Can be used to replace graphite, ceramic, glass and other pipes with lower mechanical strength

It can be used for pipe misalignment connection or to balance pipe displacement and dimensional changes caused by weather or other reasons or to eliminate high-frequency mechanical vibration
