Precautions for seamless tube production: 1. Pay attention to whether the thickness of the capillary wall is uniform. If it is found that the thickness of the capillary wall is uneven, the surface polishing treatment must be performed. In addition, whether the inside and outside of the capillary tube is flat and there are no bumps and defects. Once…
Read MoreTension reduction rolling is the last hot rolling process in the production of seamless steel pipes, which plays a decisive role in the control of product quality. The tension reduction of seamless steel pipe is a continuous rolling process without mandrel. During the rolling process, the outer diameter and wall thickness of the rolled piece are changed by the…
Read MoreAlloy tubes are divided into structural seamless tubes and high-pressure heat-resistant alloy tubes. Mainly different from the production standard of alloy pipe and its industry, annealing and tempering of alloy pipe changes its mechanical properties and achieves the required processing conditions. Its performance is higher than that of ordinary seamless steel pipes, and its chemical composition contains more Cr,…
