What is spiral seam high frequency welded steel pipe for pressure fluid transportation? This article will introduce

Welded steel pipe for low pressure fluid transportation is made to GB/T 3091 and supplied either plain, often called black pipe, or hot dip galvanized, often called white pipe. The

Welded steel pipe is also called welded pipe. It is a steel pipe made by welding steel plates or steel strips after curling.

Q355GNH is a structural weathering steel grade defined in GB/T 4171, in which Q stands for yield strength, 355 for the minimum yield value in megapascals and GNH for high atmospher

Practice has proved that thermal stress and structural stress will occur in any workpiece as long as there is phase change during the heat treatment process.

Residual stress left in steel pipe by heating, quenching and cooling is the underlying cause of distortion, cracking and premature fatigue failure. This article explains how therma
