Welded steel tube weld pores not only affect the tightness of the pipeline weld and cause pipeline leakage, but also become the induction point of corrosion, which seriously reduces the strength and toughness of the weld. The factors that cause porosity in the weld are: moisture, dirt, oxide scale and iron filings in the flux, welding components and covering…
Read MoreSeamless pipes are made of steel ingots or solid pipe blanks through perforation into capillary pipes, which are then hot-rolled, cold-rolled or cold-drawn. It occupies an important position in my country’s steel pipe industry. So what should be paid attention to when producing seamless pipes? 1) Pay attention to whether the thickness of the embryo pipe wall is uniform….
Read MoreNowadays, the surface of the welded tubes we use are required to be coated for corrosion protection. The common anticorrosion coatings for welded tubes are petroleum asphalt, epoxy coal tar asphalt, PE sheath and PE foam sheath, epoxy powder, coal tar enamel and three-layer composite structure. The more used pipe anti-corrosion methods are 3PE composite structure and single-layer powder…
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 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 MoreDegreasing method for stainless steel pipes and fittings: 1. Degreasing method of stainless steel pipe Since the stainless steel pipe only needs to be degreased, in addition to the degreasing method of the carbon steel pipe mentioned above, the large-diameter pipe can also be degreased by wiping. It is not suitable to use cotton yarn when degreasing by wiping…
