Carbon Steel Pipe

Carbon steel pipe is made of steel ingot or solid round steel through
perforation, and then hot rolled, cold rolled or cold drew.Carbon steel pipes
are divided into hot-rolled and cold-rolled (drawn) steel pipes.Hot rolled
carbon steel pipe is divided into general steel pipe, low and medium pressure
boiler steel pipe, high-pressure boiler steel pipe, alloy steel pipe, stainless
steel pipe, petroleum cracking pipe, geological steel pipe, and other steel
pipes.

〣Carbon steel pipe classification


Carbon steel pipes are divided into hot rolled and cold rolled (drawn) steel
pipes.

Hot rolled carbon steel pipe is divided into general steel pipe, low and medium
pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe,
stainless steel pipe, petroleum cracking pipe, geological steel pipe and other
steel pipe.

Cold rolled (dial) carbon steel pipe in addition to general steel pipe, low and
medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel
pipe, stainless steel pipe, oil cracking pipe, other steel pipe, also includes
carbon thin-wall steel pipe, alloy thin-wall steel pipe, stainless steel pipe,
special-shaped steel pipe. The outer diameter of hot-rolled seamless pipe is
generally greater than 32mm, and the wall thickness is 2.5-75mm. The outer
diameter of cold-rolled seamless steel pipe can be up to 6mm, and the wall
thickness can be up to 0.25mm. The outer diameter of thin-walled pipe can be up
to 5mm, and the wall thickness is less than 0.25mm.

General carbon steel pipe: is made of 10, 20, 30, 35, 45 and other high-quality
carbon junction steel 16Mn, 5MnV and other low alloy structural steel or 40Cr,
30CrMnSi, 45Mn2, 40MnB and other alloy steel hot rolled or cold rolled. 10, 20
low carbon steel manufacturing seamless pipe is mainly used for fluid conveying
pipe. 45, 40Cr and other medium carbon steel seamless pipe to manufacture
mechanical parts, such as cars, tractor parts. Generally use carbon steel pipe
to ensure the strength and flattening test. Delivery of hot-rolled steel pipes
in hot-rolled or heat-treated condition; Cold rolled and delivered in heat-
treated condition.
