1.Improve the anti-corrosion conditions of the medium In order to improve anti-corrosion conditions, the following two methods can be used for cs seamless pipes. ①Remove harmful components in the medium. For example, boiler water is heated to boiling, and then the oxygen is removed before use. ②Add corrosion inhibitor. Corrosion inhibitor is a substance that can slow down the…

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…
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 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 MoreConnection method of large diameter spiral steel pipe (SSAW): The common connection method of large-diameter spiral steel pipe is welding, but in some projects, threaded connection, flange connection, socket connection, groove connection and other forms are often used. 1. Welding, flange connection Welding and flange connection are traditional spiral steel pipe connection methods, which are far from meeting the…
