In the welding process of high-frequency steel pipe, due to the combination of skin effect, proximity effect and heat conduction, the temperature distribution gradient near the edge of the tube blank ...

1, The principle The production method of the seamless steel pipe is roughly classified into a cross rolling method and an extrusion method. The former method is to first pierce the tube...

The finished seamless steel pipe is sent to the inspection department for product quality inspection, which is an important measure to ensure the quality of the seamless steel pipe. Inspection standar...

1. The influence of the rolling temperature of the seamless steel pipe: the rolling temperature is high, pressure is small, and the head wear is small, so that the inner straight defects are also redu...

Surface striated defects are important indicators affecting the surface quality of cold-rolled products. It is very difficult to solve the problem of surface ridges in many cold rolling mills in China...

The purpose of tempering stainless steel tube is to transform quenched martensite into tempered martensite, eliminate retained austenite, reduce and eliminate internal stress, obtain high hardness, we...

The storage of seamless steel tubes requires the selection of suitable sites and warehouses, and usually requires the following conditions: (1) The site or warehouse where the steel is to be st...

Steel pipes are the most widely used pipes in urban gas projects. Its main advantages are: high strength, good toughness, large load bearing stress, good impact resistance and tightness, good plastici...

There is a certain relationship between the service life of the spiral steel pipe (SSAW) and the surface decarburization of the spiral pipe. If the surface is decarburized, the strength and wear resis...

There are many types of spiral steel pipes produced by spiral steel pipe manufacturers. In the process of loading and unloading, it is inevitable that steel pipe damage will occur. For this situation,...
