Cold Rolled Carbon Steel Structural Tubing Pipe Q345 20Mn2 20CrMo 40CrMo

High quality oil and gas round square pipeline seamless carbon steel pipe

Description:

Carbon steel pipe can be divided into seamless steel pipe, straight steel pipe, spiral steel pipe, high frequency welded steel pipe and so on.Carbon steel seamless steel pipe is a kind of long steel.
The pipe has a hollow section and is used in a large number of pipelines for fluid transportation, such as those for oil, natural gas, gas, water and some solid materials.
Generally, the outer diameter of hot-rolled seamless pipe is greater than 32mm, the wall thickness is 2.5-75mm, the outer diameter of cold-rolled seamless pipe can be up to 6mm, the wall thickness can be up to 0.25mm, and the outer diameter of thin-walled pipe can be up to 5mm, the wall thickness is less than 0.25mm, and the precision of cold rolling is higher than that of hot rolling.
General carbon steel pipe: it is made of 16Mn, 5MnV and other low-alloy structural steels, such as 10, 20, 30, 35, 45, 45 etc.Seamless pipes made of mild steel such as 10 and 20 are mainly used for fluid transportation pipes.The seamless pipe made of medium carbon steel such as 45 and 40Cr is used to make mechanical parts, such as mechanical parts of cars and tractors.Carbon steel tubes are generally used for strength and flattening tests.The hot-rolled steel pipe is delivered in the hot-rolled or heat-treated condition;Cold rolling is delivered as heat treatment.

Applications:

Rolling seamless carbon steel pipe is divided into hot rolling and cold rolling (drawing) pipe.
Hot rolled carbon steel pipe is divided into general steel pipe, low and medium pressure boiler pipe, high pressure boiler pipe, alloy pipe, stainless steel pipe, petroleum cracking pipe, geological pipe and other steel pipe, etc.
Cold rolled (dial) carbon steel pipes include general steel pipe, low-medium pressure boiler steel pipe, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, and other steel pipe, including carbon thin-walled steel pipe, alloy thin-walled steel pipe, stainless steel pipe, and special-shaped steel pipe.

Oil pipe mainly used for transport oil and gas,and also widely used as transmission fluid pipe,

such as transport oil, natural gas, coal gas, water and some solid pipeline etc.
