This news page covers seamless carbon steel pipe. The content highlights stock availability, size and dimension requirements, inspection and testing requirements. Buyers can use the page to check whether the product, grade, size range, inspection requirements and delivery details match their inquiry.
The difference between hot rolled seamless steel pipe and cold rolled seamless steel pipe:
1) Cold rolled seamless steel pipes are often small diameter, and hot rolled seamless steel pipes are often large diameter.
2) The accuracy of cold rolled seamless steel pipe is higher than hot rolled seamless steel pipe, and the price is also higher than hot rolled seamless steel pipe.
3) Hot rolled seamless pipes are divided into common steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.
4) Cold rolled/drawn seamless steel pipes are divided into common steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, as well as carbon thin wall steel pipes, alloy thin wall steel pipes, Stainless thin wall steel pipes and special shape steel pipes.
Process flow:
1)Hot rolling seamless steel tube: billet → heating → piercing → three-roll cross rolling, continuous rolling or extrusion → tube removal → sizing/reducing → cooling → billet tube → straightening → hydraulic test/Eddy current test → mark → warehouse
2)Cold drawn/rolled seamless steel pipe: billet → heating → piercing → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → billet tube → heat treatment → straightening → Hydraulic test/Eddy current test → mark → warehouse
