ASTM A53 API 5L Large Diameter Thin Wall Chinese Standard GB Q235B Spiral Welded Carbon Steel Pipes
Introduction
Carbon steel tubes are divided into hot rolled and cold rolled
(drawn) steel tubes.
Hot rolled carbon steel tubes are divided into general steel tubes,
low and medium pressure boiler tubes, high pressure boiler tubes,
alloy steel tubes, stainless steel tubes, petroleum cracking tubes,
geological tubes and other steel tubes.
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,
petroleum 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 reach 6mm and the wall thickness can reach 0.25mm. The outer
diameter of thin-walled pipe can reach 5mm and the wall thickness
is less than 0.25mm.
General carbon steel pipe: 10, 20, 30, 35, 45 and other
high-quality carbon bonded steel 16Mn, 5MnV low alloy structural
steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel hot
rolled or cold rolled. 10, 20 and other low carbon steel
manufacturing seamless pipe is mainly used for fluid pipeline. 45,
40Cr and other medium carbon steel made of seamless pipe to
manufacture mechanical parts, such as cars, tractors stressed
parts. The general use of carbon steel pipe to ensure the strength
and flattening test. Hot rolled steel pipes are delivered in hot
rolled or heat treated condition. Cold rolled delivery is heat
-treated.
