    Detailed description of seamless pipes

    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 10 #, 20 #, 35 #, 45 # as ordinary steel, 16Mn the range between ordinary steel and alloy steel tubes known as low-alloy steel pipe, steel pipe material for 27SiMn of 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo and stainless steel tube referred to as alloy steel tube. Seamless steel pipe in accordance with the uses are divided into structure; conveyance of seamless steel pipe; boiler seamless steel tubes; boiler with a high-pressure seamless steel pipe; chemical fertilizer plants with high-pressure seamless steel pipe; exploration of geological brick seamless steel pipe; oil brick probe with no pipe joints; petroleum cracking; ship with 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.
