According to the different applications,as for cold draw seamless steel pipe ,hot rolled seamless steel pipe or the hot expansion steel pipe
seamless carbon steel tubes can be divided into low pressure pipe
medium pressure pipe, high pressure boiler pipe, alloy steel pipe, petroleum cracking pipe, and for construction ,for linepipe
According to the different manufacturing methods, seamless carbon steel tubes can be divided into hot rolled seamless steel pipe,
cold rolled seamless steel pipe and cold drawn seamless steel pipe. Cold rolled has better dimensional accuracy than hot working.
