The advantages of PTFE lined piping

Steel-lined PTFE pipes and fittings meet the HG / T21562-94 standard (also can be manufactured according to ASTMF1545 standard). The product has excellent quality and has the following characteristics:

1.Operating temperature

Under the condition of strong corrosive medium, it can meet the use temperature range up to -100 ℃ ~ + 260 ℃.

2.High pressure resistance

At normal temperature, it can withstand a working pressure of 1.6Mpa. When the temperature reaches 200 ° C, it can withstand a working pressure of 1.0Mpa.

3.vacuum resistance

In the range of -100 ℃ ~ + 260 ℃, the lined pipes can be used under vacuum conditions, and the vacuum resistance can reach -0.098Mpa.


The PTFE tube is specially processed into crystallinity and sufficient thickness to ensure that the lined tube has excellent permeability resistance.

5.Solve the problem of heat expansion and cold contraction

Efficiently solves the problem of shrinkage caused by cold and heat changes in steel-lined PTFE pipes during use. It can be used in the range of 260 ℃.

6.Stub end

It can solve on-site installation problems for the pipeline engineering team, which can save labor and time.

7.Set safety vents at both ends.

8.The longest can reach 6000mm, and the loose flange can be processed and made according to customer requirements.
