How to reduce the wear of ERW welded pipes in production and ensure the quality of welded pipes? From the analysis data of ERW welded pipe scrap, it can be seen that the roll adjustment process plays a very important role in the production of welded pipes. That is to say, in the production process, if the rolls are…
Read MoreBased on the skin effect, proximity effect, eddy current thermal effect and electromagnetic induction principle of electric charge, the high-frequency welded pipe (ERW pipe) heats the part of the steel at the edge of the weld to a molten state, and achieves the purpose of welding through the extrusion of the inter-crystal bonding. Do you know what are the…

Read MoreProduction methods Stainless steel tube according to the production method is divided into two categories of stainless seamless pipe and stainless welded pipe, stainless seamless steel pipe can be divided into hot-rolled tube, cold-rolled tube, cold-drawn tube and extrusion pipe, cold drawing, cold rolling is the second Processing; welded pipe is divided into straight seam welded pipe and spiral welded pipe. Section shape…
Read MoreStraight seam welded steel pipe includes double-sided submerged arc welded longitudinal welded steel pipe (LSAW pipe) and high frequency electric resistance welded pipes (ERW pipe). The length of straight seam welded steel pipe is mainly divided into fixed length and indefinite length. This is mainly according to customer requirements. The length is generally 6-14 meters. Large diameter straight seam…
Read MoreFor plasma cutting of spiral steel pipe (ssaw), the difficulty of dust removal is: 1. When the nozzle of the plasma gun is cutting, the air is blown out in two opposite directions at the same time, so that the smoke and dust emerge from both ends of the steel pipe, and the suction port installed in one direction…
