API 2B Q235B STEEL PIPE DN300

How to adapt the finished high-pressure pipe to extreme working conditions?

According to different application scenarios, the finished pipe needs to be customized. Deep-sea pipe is made of low Mn and high Cr material and treated with slow cooling, so that the weld hardness is controlled at HV10≤280;; The pipes used in the South-to-North Water Transfer Project will be sprayed with solvent-free epoxy coating of more than 500μm on the inner wall, and the corrosion resistance will be verified by cathodic stripping test.

The transformation from a steel plate to a high-pressure pipe is not only a morphological change, but also a comprehensive embodiment of industrial precision and standards. These high-pressure pipes carrying technological breakthroughs are supporting the high-quality development of China's energy transmission and infrastructure projects and becoming an important cornerstone for the construction of an industrial power.
