ASME SA53/ASTM A53 Seamless Steel Pipe

Our seamless steel pipe conforms to ASME SA53 or ASTM A53 standard. The nominal pipe can function as stressed and pressure-bearing parts, or general-purpose pipeline conveying steam, water or gas. Since it is suitable for welding, coiling, bending, flanging and other forming treatment, the steel tubing is frequently used in the production of various pipeline, vessels, equipment and mechanical structures.
