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.
2. Seamless steel pipes for conveying fluids (GBT8163-1999). Conveying fluid pipelines on large engineering equipment. The representative material (grade) is 200345 and so on.
3. Seamless steel pipes for low and medium pressure boilers (GB3087-1999 furnace thermal steaming)
High-quality carbon structural steel hot-rolled and cold-drawn (rolled) seamless steel pipes for steam pipes, boiling water pipes and superheated steam pipes, large smoke pipes, small smoke pipes and arch brick pipes for locomotive boilers. The representative material is 10, 20 steel.
4. Seamless steel pipes for high-pressure boilers (GB5310-1995 High-quality carbon steel, alloy steel and stainless heat-resistant seamless steel pipes for the heating surface of Shangli water-tube boilers. Representative materials are 20G, 12Cr1MoVG15CrMoG, etc.
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.
