First, the characteristics of straight seam steel pipes:
Straight seam steel pipes generally refer to the use of special processes to treat ordinary steel pipes, so that the steel pipes have excellent anti-corrosion capabilities. They are generally used for waterproofing, rust prevention, acid and alkali resistance, and oxidation resistance. The processes of the parent material of straight seam anti-corrosion steel pipes include submerged arc welding straight seam steel pipes and high-frequency straight seam steel pipes. The diameter of the anti-corrosion submerged arc welding straight seam steel pipe is above 325, and the diameter of the anti-corrosion high-frequency straight seam steel pipe is below 426. According to different needs and application environments, corresponding anti-corrosion measures are taken on the inner and outer walls of the steel pipe. Common ones include epoxy coal tar anti-corrosion steel pipes, polyurethane coatings, IPN8710 water pipeline anti-corrosion coatings, anti-corrosion polymer coatings, and anti-corrosion steel pipe inner wall cement mortar anti-corrosion. Anti-corrosion steel pipes are mainly used in engineering fields with special requirements or harsh environments. After the straight seam anti-corrosion steel pipe is treated with anti-corrosion, it has the characteristics of waterproof, rust-proof, acid-base-proof, and anti-oxidation.
1. Petroleum: process pipelines for transporting corrosive media in petroleum pipelines, chemical pharmaceuticals, printing and dyeing, and other industries;
2. Firefighting: applicability to water supply pipelines for anti-sprinkling and sprinkler systems;
3. Highways: cable protection sleeves for power, communications, highways, etc.;
4. Coal mines: suitable for underground water supply and drainage, underground grouting, positive and negative pressure ventilation, gas extraction, fire sprinklers, and other pipe networks in coal mines;
5. Sewage treatment: sewage treatment discharge pipes, sewage pipes, and biological pool anti-corrosion projects;
6. Power plants: process water waste residue and return water pipelines in thermal power plants;
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 projects, gas transportation, buried water supply, and other pipelines.
Second, the use of straight seam steel pipes:
1. Pipes for pipelines. Such as seamless pipes for water, gas pipes, steam pipes, oil pipelines, and pipes for LPG trunk lines. Agricultural irrigation taps and sprinkler pipes, etc.
2. Pipes for thermal equipment. Such as boiling water pipes and superheated steam pipes for general boilers, superheated pipes, large smoke pipes, small smoke pipes, arched brick pipes, high-temperature and high-pressure boiler pipes for locomotive boilers, etc.
3. Pipes for the machinery industry. Such as aviation structural pipes (round pipes, oval pipes, flat oval pipes), automobile half-axle pipes, axle pipes, automobile tractor structural pipes, tractor oil cooler pipes, square and rectangular pipes for agricultural machinery, transformer pipes, and bearing pipes, etc.
4. Pipes for petroleum geological drilling. Such as oil drilling pipes, oil drill pipes (square drill pipes and hexagonal drill pipes), drill braces, oil pipes, oil casings, various pipe joints, geological drilling pipes (core pipes, casings, active drill pipes, drill braces, press hoops, and pin joints, etc.).
5. Pipes for the chemical industry. Such as petroleum cracking pipes, heat exchangers and pipes for chemical equipment, stainless acid-resistant pipes, high-pressure pipes for fertilizers, and pipes for transporting chemical media, etc.
6. Pipes for other departments. Such as pipes for containers (pipes for high-pressure gas cylinders and general container pipes), pipes for instruments and equipment, pipes for watch cases, pipes for injection needles and medical devices, etc.
