According to the manufacturing method, the steel pipe can be pided into two categories: seamless steel pipe and welded seam steel pipe. Among them, ERW steel pipe is the main variety of welded steel p...

Seamless steel pipes are pided into two types: hot-rolled and cold-rolled (dial) seamless steel pipes. Hot rolled seamless steel pipes are pided into general steel pipes, low and medium pressure boil...

The industrial production of large straight seam pipes (LSAW steel pipe) can be pided into the following types according to different steel pipe forming methods. 1. UOE process The so-called "UOE" pro...

Precision steel pipe is a kind of high-precision steel pipe raw material after cold drawing or hot rolling. Because there is no air oxide layer on the inner and outer walls of precision steel pipes, i...

Casing pipe and Tubing pipe made to API specifications uses seamless or electric-weld processes. Seamless pipe is defined as a wrought steel tubular product made without a welded seam. It is manufactu...

Spiral steel pipes should be subjected to mechanical performance test, flattening test and flaring test before leaving the factory, and must meet the requirements of the standard. The quality inspecti...

The seamless steel pipes we use every day need to be done-some cutting treatment and heat treatment. What are the reasons for seamless steel tubes to be treated? Seamless steel pipe cutting treatment...

As a carrier of oil and gas transmission, buried oil pipelines are a link connecting upstream and downstream (analyzed by backward status), and are important facilities for surface engineering. Becaus...

Seamless steel pipes have a hollow section and are used in large quantities as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, gas, water and certain solid materials....

Spiral welded pipe (SSAW/SAWH): a low carbon carbon structural steel or low alloy structural steel strip is rolled into a tube blank at a certain spiral angle (forming angle), and then the tube seam i...
