Seamless steel pipes are perforated from a whole round steel, and steel pipes without welds on the surface are called seamless steel pipes. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and top pipes. According to the cross-sectional shape, seamless steel pipes are divided into two types: round and special-shaped. Special-shaped pipes have square, oval, triangular, hexagonal, melon seed, star, and finned pipes. The maximum diameter is 900mm and the minimum diameter is 4mm. According to different uses, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes. Seamless steel pipes are mainly used as petroleum geological drilling pipes, petrochemical cracking pipes, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.
Advantages: It can destroy the casting structure of the ingot, refine the grain of the steel, and eliminate the defects of the microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the steel is no longer isotropic to a certain extent; the bubbles, cracks and porosity formed during casting can also be welded under the action of high temperature and pressure.
Application
1. Pipes for pipes.
Such as: seamless pipes for water, gas pipes, steam pipes, oil pipelines, and pipes for oil and natural gas trunk lines. Agricultural irrigation faucets with pipes and sprinkler irrigation pipes, etc.
2. Tubes for thermal equipment.
Such as boiling water pipes, superheated steam pipes for general boilers, superheating pipes, large smoke pipes, small smoke pipes, arch brick pipes and high temperature and high pressure boiler pipes for locomotive boilers.
3. Pipes for machinery industry.
Such as aviation structural pipes (round pipes, elliptical pipes, flat elliptical pipes), automobile semi-axle pipes, axle pipes, automobile tractor structural pipes, tractor oil cooler pipes, agricultural machinery square pipes and rectangular pipes, transformer pipes and bearings tube etc.
