Carbon steel pipes should be made of steel castings or solid round steel through perforation, and then hot-rolled, cold-rolled or cold-drawn. Carbon steel pipe plays an important role in China’s seamless steel pipe industry. Key materials are mainly Q235, 20#, 35#, 45#, 16Mn. The most important product implementation standards include national standards, American standards, Japanese standards, etc. Among them, national standards include the standards of the Ministry of Chemical Industry, Sinopec pipe fittings standards, and power engineering pipe fittings standards. Let’s take a look at the usefulness of carbon steel pipes.
Uses of carbon steel pipes:
1. Pipes for mechanical engineering. Such as airline structural tubes, automobile half shaft tubes, transmission shaft tubes, large tractor structural tubes for vehicles, tractor water cooler tubes, rectangular square tubes and rectangular tubes for agricultural locomotives, transformer tubes and rolling bearing tubes, etc.
2. Drilling pipes for petroleum geological environment. Such as: oil drilling pipes, oil drilling pipes (kelly and hexagonal drill pipes), drill jacks, oil pipelines, oil waterproof casings and various tee joints, geological environment drilling pipes (core pipes, waterproof casings, active drilling rods, drill jacks, hoops and pin connectors, etc.).
3. Chemical pipes. Such as: petroleum cracking pipes, pipes for heat exchangers and pipelines of chemical machinery and equipment, stainless steel acid-resistant pipes, air-conditioning pipes for organic fertilizers and pipes for transporting chemical plant materials, etc.
4. Tubes for pipelines. Such as: water, gas pipes, seamless pipes for compressed air pipes, oil pipelines, pipes for oil and gas main lines. Leading pipes for agricultural irrigation water and pipes for sprinkler irrigation equipment, etc.
5. Pipes for thermal equipment. Such as boiling water pipes and saturated steam pipes used in general heating furnaces, overheating pipes, large smoke pipes, small exhaust pipes, arch brick pipes and continuous high-temperature alloy steel pipes used in electric locomotive heating furnaces.
6. Managed by other departments. Such as: tubes for utensils (tubes for liquefied gas cylinders and general utensils), tubes for instruments and meters, tubes for watch cases, injection needles and tubes for medical machinery, etc.
