There are two types of galvanizing methods for seamless tubes: hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing includes wet method, dry method, lead-zinc method, redox method, etc. The main difference between different hot-dip galvanizing methods is what method is used to activate the surface of the pipe body after acid dip cleaning of the steel pipe to improve the quality…

Read More1. Grinding of thick-walled seamless nozzle: After cutting, use an angle grinder to grind the plastic layer of the nozzle. Its purpose is to prevent the plastic layer from melting or even burning during the flange welding process, damaging the pipe, and grinding the nozzle plastic layer with an angle grinder. 2. Thick-walled seamless pipe plastic coating treatment:After polishing,…
Read MoreSpiral steel pipe(ssaw) is a steel pipe with spiral seam, which is made of strip steel coil as raw material, often warmly extruded, and welded by automatic double-wire double-sided submerged arc welding process. It is mainly used in pipeline transportation of oil, natural gas, bridges, docks, roads, buildings and other projects. Welding is the most common connection method for…
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…
