What are the uses of carbon steel pipes?

Carbon steel pipes are made by piercing steel ingots or solid round steel into capillary tubes, which are then hot rolled, cold rolled, or cold drawn. Carbon steel pipes play an important role in China’s steel pipe industry. The main materials are q235, 20 #, 35 #, 45 #, and 16mn. The main execution standards include national standards, American standards, Japanese standards, etc., among which national standards also include Ministry of Chemical Industry standards, Sinopec pipe fittings standards, and power pipe fittings standards.

Mechanical engineering pipes. For example, structural pipes for airlines (round steel pipes, stainless steel pipes, flat stainless steel pipes), automotive half shaft pipes, transmission shaft pipes, structural pipes for vehicles and large tractors, pipes for water coolers for tractors, rectangular square and rectangular pipes for agricultural machinery and vehicles, pipes for transformers and their rolling bearings, etc.

Pipelines for petroleum geological environment drilling. For example, petroleum drilling pipes, petroleum drill pipes (square and hexagonal drill pipes), drilling rods, petroleum oil pipelines, petroleum waterproof casings and various tee joints, geological environment drilling pipes (core pipes, waterproof casings, active drill pipes, drilling rods, clamps and pin connectors, etc.).

Chemical pipes. For example, petroleum cracking pipes, pipes for heat exchangers and pipelines in chemical machinery equipment, stainless steel acid resistant pipes, air conditioning pipes for organic fertilizers, and pipes for transporting materials in chemical plants.

Pipes for pipelines. For example, seamless steel pipes for water, gas pipelines, compressed air pipelines, oil transmission pipelines, and pipelines for oil and gas trunk lines. Leading agricultural irrigation water pipes and sprinkler equipment pipes.

Pipes for thermal equipment. For example, boiling water pipes and saturated steam pipes used in general heating furnaces, superheater pipes, large smoke pipes, small exhaust pipes, arch brick pipes and continuous high-temperature alloy steel pipes used in electric locomotive heating furnaces.

Used by other departments. For example, tubes for vessels (liquefied gas cylinder tubes and general vessel tubes), instruments and meters tubes, watch case tubes, injection needles, and medical machinery tubes.
