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 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 MoreSeamless pipe refers to a steel ingot or solid pipe blank that is perforated into a capillary pipe, and then hot-rolled, cold-rolled or cold-drawn. Compared with solid steel such as round steel, the steel pipe is lighter in weight when the bending and torsional strength is the same, and is an economical section steel. So what are the characteristics…

Read MoreBurrs are ubiquitous in the metalworking process. No matter how advanced and sophisticated equipment you use, it will be born with the product. It is mainly due to the plastic deformation of the material and an excess iron filings generated on the edge of the processed material, especially for materials with good ductility or toughness, which are particularly prone…
