The 46th edition of API 5B was released on December 1, 2017. The standard temporarily stated that it was officially implemented on July 1, 2018. Publication 1 will be published soon. There are too man...

What is the difference between a hot-rolled seamless steel pipe and a cold-rolled seamless steel pipe? Is the usual seamless steel pipe a hot-rolled seamless steel pipe? Cold-rolled seamless steel ...

When the spiral steel pipe (SSAW) is heated, the iron, alloy, and elements on the surface of the steel react with oxygen, carbon dioxide, and water vapor in the medium to form an oxide film. The pheno...

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...
