Straight seam steel pipe generally refers to the use of a special process to carry out anti-corrosion treatment on ordinary steel pipes, so that the anti-corrosion ability of the steel pipe is generally used for waterproof, rust, acid and alkali, and oxidation resistance. The process of the base material of the longitudinal seam anti corrosive steel pipe includes the submerged arc welded longitudinally welded steel pipe and the high-frequency longitudinally welded steel pipe. The diameter of the anti-corrosive submerged arc welded straight seam steel pipe is above 325, and the diameter of the anti-corrosive 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 requirements and application environments. The common ones are mainly epoxy coal tar anti corrosive steel pipe, polyurethane coating anti corrosion, IPN8710 water pipe anti corrosive coating anti corrosive polymer coating, and anti corrosive steel pipe inner wall cement Mortar anti-corrosion, etc. Anti corrosive steel pipes are mainly used in engineering fields with special requirements or harsh environments. After the anti-corrosion treatment of the straight seam anti-corrosion steel pipe, the steel pipe has the anti-corrosion ability and has the characteristics of waterproof, anti-rust, anti-acid and alkali, and anti-oxidation.
