Product Specifications

Product Details

Seamless carbon steel pipe (Seamless carbonsteel pipe) is made of steel ingot or solid tube blank through perforation to make capillary, and then hot-rolled, cold-rolled or cold-drawn. Seamless carbon steel pipe plays an important role in my country's steel pipe industry. According to incomplete statistics, there are more than 240 seamless carbon steel pipe manufacturers in my country, more than 250 sets of seamless carbon steel pipe units, and an annual production capacity of about 4.5 million tons. From the perspective of diameter, <φ76, accounting for 35%, <φ159-650, accounting for 25%. In terms of varieties, general-purpose pipes are 1.9 million tons, accounting for 54%; oil pipes are 760,000 tons, accounting for 5.7%; hydraulic struts and precision pipes are 150,000 tons, accounting for 4.3%; stainless pipes, bearing pipes, and automobile pipes total 50,000 tons. tons, accounting for 1.4%. The specifications of seamless steel pipes are expressed in millimeters of outer diameter * wall thickness.

Implementation standard:

Due to their different manufacturing processes, seamless steel pipes are divided into hot-rolled (extruded) seamless steel pipes and cold-drawn (rolled) seamless steel pipes. Cold drawn (rolled) tubes are divided into two types: round tubes and special-shaped tubes. Seamless steel pipes are divided into the following varieties due to their different uses:1. Seamless steel pipe for structure (GBT8162-2008). Mainly used for general structure and mechanical structure. Its representative material (brand): carbon steel, 20, 45 steel; alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, etc.2. Seamless steel pipes for conveying fluids (GBT8163-2008). It is mainly used for conveying fluid pipelines in engineering and large-scale equipment. The representative material (grade) is 20, Q345, etc.3. Seamless steel pipes for low and medium pressure boilers (GB3087-2008) are used to manufacture various structures of low and medium pressure boiler superheated steam pipes, boiling water pipes and superheated steam pipes, large smoke pipes, small smoke pipes and arch bricks for locomotive boilers Hot-rolled and cold-drawn (rolled) seamless steel pipes of high-quality carbon structural steel for pipes. The representative material is 10, 20 steel.4. High-pressure boiler seamless steel pipe (GB5310-2008) is a high-quality carbon steel, alloy steel and stainless heat-resistant steel seamless steel pipe used to manufacture the heating surface of water-tube boilers with high pressure and above. The representative materials are 20G, 12Cr1MoVG, 15CrMoG, etc.5. Seamless steel pipe for high-pressure fertilizer equipment (GB6479-2000) is a high-quality carbon structural steel and alloy steel seamless steel pipe suitable for chemical equipment and pipelines with a working temperature of -40~400℃ and a working pressure of 10~30Ma. The representative materials are 20, 16Mn, 12CrMo, 12Cr2Mo, etc.Classification of seamless carbon steel pipes: seamless steel pipes are divided into two categories: hot-rolled and cold-rolled (dial) seamless steel pipes.Hot-rolled seamless steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.
