Most of the structural seamless steel pipes work under relatively large dynamic loads. They are subjected to tension, compression, bending, torsion or shearing. Some surfaces also have friction, requiring certain wear resistance and so on. In summary, parts operate under various compound stresses. Structural seamless steel pipes are mainly structural parts of various machines and mechanisms, such as shafts,…
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 MoreSeamless steel pipe VS welded steel pipe: 1. Seamless steel pipe is a kind of strip steel with no joints around and a hollow section, which is widely used as a pipeline for conveying fluids. Compared with solid steel, it is lighter in weight with the same bending and torsional strength. It is an economical section steel and is…
Read MoreWeld leveling of straight seam steel pipe (lsaw/erw): Due to the impact of the welding current and the influence of gravity, the internal weld of the pipe will protrude, and the external weld will also sag. If these problems are used in an ordinary low-pressure fluid environment, they will not be affected. If it is used in high temperature,…
Read MoreSeamless steel pipe installation and precautions: A. Construction preparation (1) Operating conditions The ground of the pipeline trench is completed; the bricklaying of the pipeline well is completed. (2) Material requirements Various specifications and models of pipes are complete. (3) Main equipment Cutting machine, electric welding machine, polishing machine, electric hammer, etc. B. Quality requirements The allowable deviation of…
Read MoreStraight seam welded pipe: a steel pipe with the weld seam parallel to the longitudinal direction of the steel pipe. According to the forming process, it is divided into high frequency straight seam steel pipe (erw pipe) and submerged arc welded straight seam steel pipe (lsaw pipe). 1. Construction preparation before use of straight seam welded pipe The pipeline…
Read MoreOil casing pipe is the lifeblood of keeping oil wells running. Due to different geological conditions, the downhole stress state is complex, and the comprehensive action of tension, compression, bending and torsional stress acts on the pipe body, which puts forward higher requirements on the quality of the casing itself. Once the casing itself is damaged for some reason,…
