Why can't non-metallic pipes or stainless steel pipes be used as long-distance pipelines

Why can't non-metallic pipes or stainless steel pipes be used as long-distance pipelines

Keywords :Why can't non-metallic pipes or stainless steel pipes be used as long-distance pipelines        Update : 2022-10-09        View(s) : 521

Oil and gas transportation through pipelines requires a certain pressure to achieve. The longer the pipeline, the higher the pressure required for oil and gas transportation. The pressure of long-distance pipelines is generally between a few MPa and a dozen MPa, so the pipeline must have Sufficient ...
