How to check whether the steel-lined PTFE pipeline is qualified? The following editor will introduce to the majority of users:

Test, inspection and application scope of inner PTFE lining layer

1.After the pipes and pipe fittings are subjected to a hydraulic test at 1.5 times the design pressure.

2. After the water pressure test is performed on the PTFE lining layer involved in the lining, 100% integrity inspection is carried out, and the leakage point inspection method adopts the electric spark test

3. The scope of use

a. Operating temperature -20~200℃

b. Use pressure ≤2.5Mpa

c. Allow negative pressure DN≤250mm is -0.09Mpa, DN>250mm is -0.08Mpa

d. It can transport any concentration of strong acids, strong bases, organic solvents, strong oxidants, toxic, volatile, and flammable chemical media.
