The material classification
Steel pipe can be divided into carbon pipe, alloy pipe, stainless steel pipe and so on.
Carbon pipe can be divided into ordinary carbon steel pipe and high quality carbon structure pipe.
Alloy tube can be divided into: low alloy tube, alloy structure tube, high alloy tube, high strength tube. Bearing tube, heat and acid resistant stainless tube, precision alloy (such as cutting alloy) tube and high temperature alloy tube, etc.
Connection type classification
Steel pipe can be divided into light pipe (pipe end without thread) and wire pipe (pipe end with thread) according to the connection mode of pipe end.
Wire tube is divided into: ordinary wire tube and tube end thickened wire tube.
Thickening wire pipe can also be divided into: outer thickening (with external thread), inner thickening (with internal thread) and inner and outer thickening (with internal and external thread) and other ground wire pipe.
If the thread type can also be divided into: ordinary cylindrical or conical thread and special thread and other ground thread tube.
In addition, according to the needs of users, wire pipes are generally equipped with pipe joints delivery.
Classification of plating characteristics
According to the surface coating characteristics of steel tube can be divided into: black tube (not coated) and coated tube.
Galvanized pipe, aluminum pipe, chromium pipe, aluminized pipe and other alloy layer of steel pipe.
Coating pipe has outer coating pipe, inner coating pipe, inner and outer coating pipe. Commonly used coatings are plastic, epoxy resin, coal tar epoxy resin and a variety of glass anti-corrosion coating materials.
Galvanized pipe is divided into: KBG pipe, JDG pipe, threaded pipe and so on.
Classification of use
1. Pipes for pipelines. Such as: water, gas pipe, steam pipe seamless pipe, oil transmission pipe, oil and gas trunk pipe. Agricultural irrigation faucet with pipe and sprinkler irrigation pipe.
2. Pipes for thermal equipment. Such as general boiler with boiling water pipe, overheated steam pipe, locomotive boiler with heat pipe, big smoke pipe, small smoke pipe, arch brick pipe and high temperature and pressure boiler pipe.
3. Pipes for mechanical industry. Such as aviation structure tube (round tube, elliptical tube, flat elliptical tube), automobile half shaft tube, axle tube, automobile tractor structure tube, tractor oil cooler tube, agricultural machinery with square tube and rectangular tube, transformer tube and bearing tube, etc..
4. Petroleum geology drilling pipe. Such as: oil drilling pipe, oil drill pipe (kelly and hexagonal drill pipe), drilling, oil pipe, oil casing and all kinds of pipe joint, geological drilling pipe (core pipe, casing, active drill pipe, drilling, hoop and pin joint, etc.).
5. Tubes for chemical industry. Such as: petroleum cracking pipe, chemical equipment heat exchanger and pipe with pipe, rust acid resistant pipe, chemical fertilizer with high pressure pipe and transport chemical medium with pipe.
6. For other departments. Such as: container tube (high pressure gas cylinder tube and general container tube), instrument instrument tube, hand case tube, injection needle and medical instrument tube.
