A53 Seamless & Welded Carbon Steel Pipe

Classification :

ASTM A53 is a carbon steel alloy that can be used as structural steel or for low pressure piping. ASTM A53 (ASME SA53) carbon steel pipe is a specification covering seamless, welded black and hot-dip galvanized steel pipe from NPS 1/8 "to NPS 26. A53 is suitable for pressure and mechanical applications, as well as for general use in steam, water, gas and air lines.
