Read MoreThe production method of seamless steel pipe is roughly divided into the cross-rolling method and the extrusion method. The former method is to pierce the tube with oblique rolls and then stretch it with a rolling mill. This method has a fast production speed, but has higher requirements on the processing performance of the tube blank, and is mainly…
Read MoreWe use stainless steel seamless pipes many times now, and many customers face a lot of problems when selecting materials, looking at the uneven prices on the market and related problems, there is no final solution. Here are some tips to share with you, so as to improve the cost-effectiveness of products when selecting finished products in the later…
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 MoreComparison of ERW pipe and seamless pipe (SMLS): (1) Superior tube blank quality Compared with the tube blank of SMLS steel pipe, the design of chemical composition of high frequency welded pipe (ERW) is more scientific and reasonable. ERW special steel grades are characterized by high purity. Through de-S, de-P, degassing, Ca treatment and other methods, the content of…
Read MoreFor carbon steel pipe (CS pipe), it should be degreased first and then pickled, because grease is insoluble in acid solution. If pickling is performed first, neither the oil stains nor the rust covered by the oil stains can be removed. Degreasing pickling method for carbon seamless steel pipe: At present, the tank immersion method is often used in…
Read MoreDecarburization is a phenomenon in which the surface carbon content of the steel pipe (CS seamless pipe) decreases during the heat treatment process. The essence of decarburization is that the carbon atoms in the steel tube react with the furnace atmosphere such as hydrogen or oxygen at high temperature to form methane or carbon monoxide. Decarburization is the result…
