Application
For mechanical and pressure use, and also for transporting steam, water, gas and etc. Mill test certificates will be issued according to EN10204/3.1B. ASTM A53 pipe (also referred to as ASME SA53 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. Materials and Manufacture The steel for both seamless and welded pipe shall be made by one or more of the following processes: open-hearth, electric furnace, or basic-oxygen. The weld seam of electric-resistance welded pipe in Grade B shall be heat treated after welding. Applications: heat exchangers, condensers, heat transfer equipment and similar pipes.
