Details of the thick-walled seamless steel pipe

Thick-walled seamless steel pipe production manufacturing process can be divided into cold drawn, cold-rolled, hot-rolled, four basic ways of thermal expansion, pipe material is *0 #, *0 #, *5 #, *5 # asordinary steel, *6Mn the range between ordinary steel and alloy steel tubes known as low-alloy steelpipe, steel pipe material for *7SiMn of *2Cr1MoV, *0CrMo**0, *5CrMo, *5CrMo and stainless steel tubereferred to as alloy steel tube. Seamless steel pipe in accordance with the uses are divided intostructure; conveyance of seamless steel pipe; boiler seamless steel tubes; boiler with a high-pressureseamless steel pipe; chemical fertilizer plants with high-pressure seamless steel pipe; exploration ofgeological brick seamless steel pipe; oil brick probe with no pipe joints; petroleum cracking; shipwith seamless steel tubes; cold-drawn cold-rolled precision seamless steel tubes; a variety of alloy tube.

Seamless steel pipe, said method for diameter, wall thickness, thick-walled seamless steel tubes for mechanical processing, coal, hydraulic steel, a variety of uses.
