In addition to iron, the main elements contain carbon steel, manganese and silicon, sulfur, phosphorus, etc. As the criterion of classification, the types of steel pipe is led to be diverse. There are seven main classification methods in the modern market.
If comply with the discipline of texture of material,if obey the rule of the quality of classification, it can be divided into ordinary steel pipe, steel pipe, senior high quality steel pipe quality. It can be divided into carbon steel and alloy pipe, stainless steel pipe. Carbon steel pipe can be divided into ordinary carbon steel and high quality carbon structural tube. Whereas the alloy tube can be divided into: low alloy steel pipe, alloy pipe, alloy pipe, high strength tube. Bearing tube, heat and acid resistant stainless steel tube, precision alloy pipe and high temperature alloy tube
If depend on the criteria of the production method, it can be divided into seamless steel pipe and pipe joints straight seam steel tube, referred to as a steel pipe.
If abide by the law of connection mode, we can divide it into The light pipe and threading pipe.
If comply with the discipline of coating characteristics, it can be divided into Clarinet and plating coating tubes.
And if in accordance with the purposes to classification, it can be divided into a large number of types, including pipes, tubes, thermal equipment with mechanical industrial pipe, petroleum geology drilling pipe, chemical pipe, other departments tube.
If abide by the rule of section shape, it can be divided into round steel pipe, profiled steel, section of steel pipe and variable cross-section steel pipe. And variable cross-section steel pipe is the pipe along the tube length to the section shape, inner and outer diameter and wall thickness, periodic or non periodic change.
In short, steel grades and specifications of steel products is very wide, it also has a wide range of performance requirements.
