Lifetime of SSAW Steel Pipe

Date:2018-09-04    keywords:lifetime of ssaw steel pipe
SSAW steel pipe itself has no life limit, and the service life is mainly related to the operating environment and production process. Spiral steel pipe operating environment is relatively poor In order to extend the service life, the outer wall and inner diameter of the steel pipe are preserved.

Anti-corrosion steel pipe refers to a steel pipe that has been treated by anti-corrosion technology and can effectively prevent or slow down the corrosion phenomenon caused by chemical or electrochemical reaction during transportation and use. The anti-corrosion steel pipe can effectively prevent or slow down the corrosion and prolong the service life of the steel pipe and reduce the running cost of the steel pipe.

There are many steel pipeline anti-corrosion coatings in China, such as petroleum asphalt, PE jacket and PE foam jacket, epoxy coal tar pitch, coal tar enamel, epoxy powder and three-layer composite structure, and epoxy coal tar pitch cold-wrapped belt (PF type). , rubber-plastic epoxy coal tar cold tape (RPC type), etc., the most widely used pipe anti-corrosion methods are three-layer PE composite structure, single-layer powder epoxy, PF cold-wrapped tape, RPC-type cold Wrap.
