Price analysis of carbon steel welded steel pipe for municipal water supply and drainage pipeline the weld hole of spiral steel pipe specially used in sewage treatment plant not only affects the tightness of pipeline weld, causes pipeline leakage, but also becomes the point of corrosion, seriously reduces the strength and toughness of weld.The factors that cause porosity in welding seam include: moisture, dirt, oxide skin and iron scrap in flux, welding composition and covering thickness, surface quality of steel plate, steel plate edge plate treatment, welding process and steel pipe forming process, etc.Flux composition.When welding CaF2 and SiO2 with appropriate amount, it will react to absorb a large amount of H2 and generate HF with high stability and insoluble in liquid metal, thus preventing the formation of hydrogen pores.
