Characteristics of
straight seam steel pipes: Straight seam steel pipes generally refer to the use of special processes to carry out anti-corrosion treatment on ordinary steel pipes, so that the steel pipes have excellent anti-corrosion capabilities, and are generally used for waterproofing, rust prevention, acid and alkali resistance, and oxidation resistance. characteristic. The base metal technology of straight seam anticorrosion steel pipe includes submerged arc welding straight seam steel pipe and high frequency straight seam steel pipe. The caliber of the anti-corrosion submerged arc welded straight seam steel pipe is above 325, and the caliber of the anti-corrosion high-frequency straight seam steel pipe is below 426.
Corresponding anti-corrosion measures are carried out on the inner and outer walls of steel pipes according to different requirements and application environments. The common ones are epoxy coal tar pitch anti-corrosion steel pipes, polyurethane anti-corrosion coatings, IPN8710 water diversion pipeline anti-corrosion coatings, anti-corrosion polymer coatings, and cement on the inner walls of anti-corrosion steel pipes. 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 anti-corrosion ability and has the characteristics of waterproof, anti-rust, anti-acid and alkali, and anti-oxidation.
1. Petroleum: oil pipelines, process pipelines for transporting corrosive media in chemical, pharmaceutical, printing, and dyeing industries;
2. Fire protection: Applicability to water supply pipelines of sprinkler and sprinkler systems;
3. Expressway: cable protection casing for electric power, communication, expressway, etc.;
4. Coal mine: suitable for underground coal mine water supply and drainage, underground spray grouting, positive and negative pressure ventilation, gas drainage, fire sprinkler, and other pipe networks;
5. Sewage treatment: sewage treatment discharge pipes, sewage pipes, and bio-pool anti-corrosion projects;
6. Power plants: thermal power plant process water waste residues, and return water pipelines;
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, water supply engineering, gas transmission, buried water transmission, and other pipelines.
The use of straight seam steel pipe:
1. Pipeline. Such as water, gas pipes, seamless pipes for steam pipes, oil pipelines, and pipes for LPG trunk lines. Agricultural irrigation water belt pipes and sprinkler irrigation pipes, etc.
2. Pipes for thermal equipment. Such as boiling water pipes and superheated steam pipes for general boilers, superheated pipes for locomotive boilers, large smoke pipes, small smoke pipes, arch brick pipes, and high-temperature and high-pressure boiler pipes.
3. Pipes for the machinery industry. Such as structural tubes (round tubes, oval tubes, flat oval tubes), automobile half-axis tubes, axle tubes, automotive tractor structural tubes, tractor oil cooler tubes, square and rectangular tubes for agricultural machinery, transformer tubes, and bearing tubes Wait.
4. Pipes for petroleum geological drilling. Such as oil drilling pipe, oil drill pipe (kelly and hexagonal drill pipe), drill jack, oil tubing, oil casing, various pipe joints, geological drilling pipe (a core pipe, casing, active drill pipe, drill jack, by hoop and pin joints, etc.).
5. Pipes for the chemical industry. Such as petroleum cracking pipes, chemical equipment heat exchangers and pipes, stainless acid-resistant pipes, high-pressure pipes for fertilizers, and pipes for transporting chemical media, etc.
6. Managed by other departments. Such as tubes for containers (tubes for high-pressure gas cylinders and general container tubes), tubes for instruments, tubes for watch cases, tubes for injection needles and medical equipment, etc.
