Characteristics of straight seam steel pipe:
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 resistance, and oxidation resistance. The process of the base material of the longitudinal seam anticorrosive steel pipe includes the submerged arc welded longitudinal seam steel pipe and the high-frequency longitudinal seam steel pipe. The diameter of anticorrosive submerged arc welded straight seam steel pipe(
lsaw steel pipe) is above 325, and the diameter of anticorrosive high frequency straight seam steel pipe(
erw 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 anticorrosive steel pipe, polyurethane coating anticorrosion, IPN8710 water diversion pipeline anticorrosive coating, anticorrosive polymer coating, and anticorrosive 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 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, rust, acid and alkali resistance, and oxidation resistance.
Uses of straight seam steel pipes:
1. Petroleum: process pipelines for transporting corrosive media in petroleum transportation pipelines, chemical and pharmaceutical industries, printing and dyeing industries;
2. Fire protection: Applicability to water supply pipelines of sprinkler and sprinkler systems;
3. Expressways: cable protection sleeves for power, communications, and expressways;
4. Coal mines: suitable for underground water supply and drainage, underground spraying, positive and negative pressure ventilation, gas drainage, fire sprinkler and other pipe networks;
5. Sewage treatment: sewage treatment discharge pipes, sewage pipes and biological pond anticorrosion projects;
6. Power plant: process water waste residue and return water conveying pipeline in thermal power plant;
7. Agriculture: agricultural irrigation pipes, deep well pipes, drainage pipes and other networks;
8. Municipal engineering: suitable for high-rise building water supply, heating network heating, tap water engineering, gas transportation, buried water transportation and other pipelines.
