According to the different applications, seamless carbon steel tubes can be divided into low pressure tube, medium pressure tube, high pressure boiler tube, alloy steel tube, petroleum cracking tube, and some other.
According to the different manufacturing methods, seamless carbon steel tubes can be divided into hot rolled seamless steel tube, cold rolled seamless steel tube and cold drawn seamless steel tube. Cold rolled has better dimensional accuracy than hot working.
