Alloy tube (Alloy pipe) is a kind of seamless steel tubes, and its performance is much higher than the average small-diameter seamless steel pipe plant, because this steel which contains Cr q345 more small-diameter steel pipe, its high temperature resistance, low temperature corrosion-resistant performance is matched by other 20cr small caliber seamless steel pipe, alloy pipe so in the petroleum, aerospace, chemical, electric power, boiler, military and other industries more extensive use GB / T17396-2007 (hydraulic prop with hot rolled seamless steel pipe). Mainly for the production of coal and hydraulic support cylinders, columns, and other hydraulic cylinders, columns. The representative material for 20,45,27SiMn like. GB3093-1986 (diesel engine with high-pressure seamless steel pipe). Mainly used for high-pressure diesel injection system tubing. It is generally cold drawn steel tubes, which represents material for 20A. GB / T3639-2007 (drawn or cold rolled precision seamless). Is mainly used for mechanical structure, the carbon pressure equipment, high dimensional accuracy is required, and good surface finish steel. The representative of material 20,45 steel. GB / T3094-1999 (cold drawn seamless steel pipe shaped). Mainly used for the production of structural parts and components, the material for high-quality carbon structural steel and low alloy steel.
