What is the material of seamless steel tube?

　　The seamless steel pipe is made of ordinary and high-quality carbon structural steel (Q215-A to Q275-A and 10 to 50 steel), low alloy steel (09MnV, 16Mn, etc.), alloy steel, stainless acid and acid resistant steel.

　　Seamless steel tubes have hollow sections and are used in large quantities as pipes for transporting fluids, such as pipes for transporting petroleum, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, the steel pipe has a lighter weight when it has the same bending and torsional strength, and is an economical section steel. The material of the seamless steel pipe is different and its use is different.

What is the purpose of oil casing pipe?
