ASME SA53-TypeS/B is a general-purpose seamless steel pipe with tensile strength ≥ 415 (MPa) and yield strength ≥ 240 (MPa); executive standard: ASTM A 53.
ASTM A 53 welded pipe is suitable for pressure piping systems, pipeline pipes and general purpose pipes with temperatures below 350°C.
ASME SA53 Class B ERW pipe is available in a wide range of sizes and can be customized to suit the user's needs. Common size parameters include: usually ranging from smaller sizes (such as 1/8 inch or less) to larger sizes (such as 48 inches or larger). The specific selection of the outer diameter depends on factors such as fluid flow, pressure requirements, and installation space.
ASME SA53 Grade B steel pipe is general purpose pipe suitable for moderate pressure and temperature service and is typically used to transport water, steam, air, gas, oil and other fluids. These steel pipes are manufactured through a resistance welding process, in which the edges of the steel plates are welded using heat generated by electrical resistance to form a continuous weld.
