1) Can seamless steel tube be galvanized? Seamless steel tube refers to a steel pipe that is perforated from a whole round steel and has no welds on the surface. It is widely used. Ordinary galvanized pipes are generally made of welded pipes. Can seamless steel tubes be galvanized? The answer is To be sure, galvanizing treatment is to…
Read MoreA) What are the two galvanizing processes for square and rectangular tubes? Galvanized square tube, also known as galvanized square tube, is a square tube that has been galvanized. According to different production processes, galvanized square tube can be divided into two types: hot-dip galvanized square tube and cold-galvanized square tube: 1. Hot-dip galvanized square tube It is a…
Read MoreSubmerged arc welding technology is the welding process of SSAW steel pipe and LSAW steel pipe. During the welding process, in addition to insufficient penetration, burn-through and poor formation caused by improper welding process parameters, there will also be pores, slag inclusions, cracks, etc. Defects. This article mainly introduces the main reasons and preventive measures for porosity in submerged…
Read MoreThe surface treatment of seamless pipe is one of the key factors in determining the anti-corrosion life of the pipe. In the practical application of seamless pipe, the surface of seamless pipe is usually descaled in order to prolong its service life. The descaling of seamless pipe is divided into tool descaling and spray descaling. So what should be…

Read MoreWelded 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…
