A Review of Manufacturing Process of Polyethylene Pipe and Connectors For Applying in High-Pressure Natural Gas Pipelines

In this article various pipes used for transporting of gas are introduced and pros and cons of each one are elucidated. the pipes are categorized in three different subgroups including metallic, polymeric and metallicwire reinforced polymeric pipes. metallicwire reinforced polymeric pipes are nominated as the best option for usage in high pressure pipelines transporting natural gas. as a result, some information about major manufacturers of this kind of polymeric pipes, raw material, production process and metallicwire orientation are presented. finally, from economical point of view, some calculations are done to estimate required amount of polymer and metallicwire to manufacture such pipes. it is also possible to compare their manufacturing cost with usual metallic and polymeric pipes.
