Seamless pipe for gas transmission

Seamless steel pipes for gas transmission are generally large-diameter seamless steel pipes, and large-diameter seamless steel pipes require heat expansion if they have a particularly large diameter.

The seamless steel pipe for gas transmission generally expands the diameter of the pipe body by heating the pipe body. The number of expansions is mainly determined by the diameter of the steel pipe to be produced. The seamless steel pipe for pipelines can be treated with anti-corrosion and heat treatment according to the use environment. The types of anti-corrosion mainly include 3pe, epoxy coal tar pitch, epoxy powder and so on. The types of insulation are mainly polyurethane foam and steel sleeve steel composite insulation pipes. The choice of the process depends on the specific conditions of use and the environment.
