The manufacture of the thick wall seamless steel tube production process can be divided into cold drawing, cold-rolled, hot-rolled, thermal expansion four basic way, the material of steel pipe for 10 #, 20 #, 35 #, 45 # called common steel, 16 mn between common steel and alloy steel pipe is called the low alloy steel pipe, steel pipe material for 27 simn, 12 cr1mov, 10 crmo910, 15 crmo, 35 crmo collectively known as the alloy steel pipe and stainless steel pipe.According to the purpose can be divided into structure with seamless steel tube;Delivery with seamless steel tube;Boiler seamless steel tube;Boiler with high-pressure seamless steel tube;Chemical fertilizer equipment with high-pressure seamless steel tube;Geologic brick, seamless steel tube;Brick of oil exploration in seamless steel tube;Seamless steel tube used in oil cracking;Shipping with seamless steel tube;Cold drawn cold rolled precision seamless steel tube;All kinds of alloy pipe.
Seamless steel pipe, said method for * wall thickness, outer diameter thick wall seamless steel tube is mainly used in mechanical processing, coal mining, hydraulic steel, such as a variety of purposes.
