Characteristics of straight seam steel pipes: Straight seam steel pipes generally refer to the use of special processes to perform anti-corrosion treatment on ordinary steel pipes, so that the steel pipes have excellent anti-corrosion capabilities. They are generally used for waterproofing, anti-rust, anti-acid and alkali, anti-oxidation, etc. characteristic. The base metal processes for straight seam anti-corrosion steel pipes include submerged arc welded straight seam steel pipes and high-frequency straight seam steel pipes. The diameter of the anti-corrosion submerged arc welded straight seam steel pipe is above 325, and the diameter of the anti-corrosion high-frequency straight seam steel pipe is below 426. Corresponding anti-corrosion measures are taken for the inner and outer walls of steel pipes according to different needs and application environments. Commonly used ones include epoxy coal pitch anti-corrosion steel pipes, polyurethane anti-corrosion coatings, IPN8710 water diversion anti-corrosion coatings, anti-corrosion polymer coatings, and anti-corrosion steel pipe inner wall cement. Mortar anti-corrosion, etc. Anti-corrosion steel pipes are mainly used in engineering fields with special requirements or harsh environments. After anti-corrosion treatment, the straight-seam anti-corrosion steel pipe can resist corrosion and has the characteristics of waterproof, anti-rust, anti-acid and alkali, anti-oxidation, and other properties.
