What is the difference between PTFE lined pipe and rubber lined pipe?
What is the difference between PTFE lined pipe and rubber lined pipe? Tetrafluoro is a polymer of tetrafluoroethylen, short for PTFE. Polytetrafluoroethylene (Poly tetra fluoroethylene, abbreviated as PTFE), is generally called “non-stick coating” or “easy to clean material”. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all […]
PTFE pipeline is the first choice for industrial sewage lining
Steel-lined PTFE pipe is a kind of green plastic pipe with the most anti-corrosion, wear-resisting, energy saving and environmental protection. Its wide application has accelerated the process of new environmental protection roads in mines to a certain extent. It not only realizes the low-carbon and environmental protection of mine operation, but also saves cost and […]
