ASTM A 53 covers seamless and welded steel pipe of nominal wall thickness. The surface state is usually black and hot-dip galvanized. ASTM A 53 is used primarily for pressure and mechanical applications and also for the transportation of steam, water, and gas line piping.
ASME SA 53 Seamless Pipes are low carbon steel pipes with 0.25% carbon content and 0.95% manganese content, CSC STEEL Exports ASME SA 53 Pipes in the form of Seamless and Welded Black and Hot Dip Galvanized Steel Pipes in various sizes. It is also called low carbon steel pipe and is easy to produce. ASTM A53 pipe is manufactured to ASME specifications. Since it is a low-carbon steel, surface hardness can only be increased by carburizing.
