Steel pipe price list
Steel pipe (steel? The development of production technology began with the tubes made by bicycles. 19? The development of oil at the beginning of the century, the manufacture of ships, boilers and planes during the two world wars, the manufacture of thermal power boilers after the second world war, the development of chemical industry, and the drilling, production and transportation of oil and natural gas all strongly promoted the development of steel pipe industry in terms of variety, output and quality.

Steel pipe specification
The diameter of pipeline can be divided into outer diameter, inner diameter and nominal diameter. The outside diameter of seamless steel pipe is indicated by the letter D, followed by the size and wall thickness of the outside diameter. For example, a seamless steel pipe with an outer diameter of 108 and a wall thickness of 5MM, and a plastic pipe is also expressed with an outer diameter, such as De63. Others, such as reinforced concrete pipes, cast iron pipes and galvanized steel pipes, are represented by DN, and nominal diameters are generally used in design drawings. The nominal diameter of a pipeline is not equal to its inner diameter and outer diameter. For example, seamless steel pipes with a nominal diameter of 100MM include 102*5 and 108*5. 108 is the outside diameter of the pipeline, and 5 represents the wall thickness of the pipeline. Therefore, the inner diameter of the steel pipe is (65438+). It can also be said that the nominal diameter is a specification name of a pipe diameter close to the inner diameter, but not equal to the inner diameter. Therefore, the use of nominal diameters in design drawings is to determine the structural dimensions and connection dimensions of pipes, fittings, valves, flanges, gaskets, etc. According to the nominal diameter, the nominal diameter is indicated by the symbol DN. If the outside diameter is indicated in the design drawing, a pipeline specification comparison table shall be made to indicate the nominal diameter and wall thickness of a pipeline.

The above is the basic knowledge about steel pipes shared by Bian Xiao. I think everyone has a deeper understanding of steel pipes after reading them. Steel pipes have many uses, such as seamless pipes for drinking water, gas pipes at home, steam pipes, oil pipelines in the oil industry and steel pipes for oil and gas trunk lines. Agricultural irrigation faucets and sprinkler irrigation pipes with pipes are also made of steel pipes. Besides, boiling water pipes, boiler superheated steam pipes, superheated pipes, smoke exhaust pipes, arched brick pipes and pipes for high-pressure boilers are all steel pipes.
