ASTM A53 Structural Steel Tube

ASTM A53 (ASME SA53) Carbon Steel Pipe is a specification that covers seamless and welded black and hot-dipped Galvanized Steel Pipe in NPS 1/8″ to NPS 26.  A 53 is intended for pressure and mechanical applications and is also acceptable for ordinary uses in steam, water, gas, and air lines.
Structural seamless pipes are seamless pipes for general structures and mechanical structures. It is a variety of Seamless Steel Pipes due to their different uses.
Structural steel seamless pipes are hot-rolled (extruded, expanded) and cold-drawn (rolled) steel pipes and structural parts and parts that are widely used in chemical, petroleum, textile, medical, food, machinery and other industries. ) seamless tube.
