ASTM A53 Grade B is a standard specification devised by ASTM (American Society for Testing and Materials) for black and hot-dipped, zinc-coated, welded, and seamless steel pipe. In various industries, ASTM A53 Grade B ERW (Electric Resistance Welded) steel pipe is often employed to transfer water, gas, and oil. Here are some essential features and specifications of ASTM A53 Grade B ERW steel pipe.
