The classification of carbon steel pipe


The classification of carbon steel pipe
Carbon steel pipe of the hot-rolled and cold rolled (drawn) two types of steel pipe.
Hot-rolled carbon steel pipe divided into general steel pipe, low and medium pressure boiler pipe, high-pressure boiler steel pipes, alloy steel pipe, stainless steel, petroleum cracking tubes, geological steel pipe and other steel pipes, etc..CARBON STEEL
Rolled (allocated) carbon steel pipe in addition to the points in general steel pipes, low pressure boiler pipe, high-pressure boiler steel pipe, steel pipe, stainless steel pipe, petroleum cracking tubes, other steel pipes, carbon steel tubes, alloy steel tubes, not rust thin-walled steel pipes, shaped steel tube. Generally greater than the hot-rolled seamless pipe diameter 32mm, wall thickness 2.5-75mm, cold-rolled seamless steel pipe at the diameter to 6mm wall thickness can be 0.25mm, thin-walled tube diameter from 5 mm wall thickness less than 0.25 mm, cold-rolled hot-rolled high dimensional accuracy.
General carbon steel pipe: Results 10,20,30,35,45 and other high-quality carbon steel 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel hot-rolled or cold rolled steel. 10, 20 and other low-carbon steel seamless pipe for fluid transportation pipeline. 45,40 Cr and in carbon steel seamless pipe used for the manufacture of mechanical parts, such as automobiles, tractors force components. General carbon steel pipe to ensure the strength and flattening test. Hot-rolled steel, hot-rolled state or heat treatment delivery; cold rolling to heat treatment delivery.
