Carbon Steel ASTM A53 Seamless Pipes:

Carbon Steel ASTM A53 pipe is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas, and air lines. It is suitable for welding, and suitable for forming operations involving coiling, bending, and flanging, subject to certain qualifications.
