Thick-walled spiral welded steel pipes are welded using an electric arc welding method under a flux layer. The heat generated by the electric arc burning between the flux and welding wire under the flux layer melts the base metal and the welding wire/fluid, forming the weld.During use, the equivalen
READ MOREFirst, can anti-corrosion steel pipes be exposed to rain? While the anti-corrosion layer of anti-corrosion steel pipes is waterproof, excessive immersion in rainwater can negatively impact it. Furthermore, the better the material and quality of the anti-corrosion layer, the stronger its resistance t
READ MOREFirst, what is a 3PE anti-corrosion steel pipe?As a terminal technology product in the steel pipe industry chain, anti-corrosion steel pipe has always occupied a very important position in the industry. In recent years, with the development and application of new anti-corrosion technologies for stee
