A53 Seamless & Welded (ERW) Steel Pipe
ERW (Electric Resistance Welded) round steel tube and pipe is available in a large selection of diameters and wall thickness. The quality of the tubes is assured through our rigorous supplier selection process and is delivered to you in full compliance to the standards like: API 5L, ASTM A53, BS1387, EN10219, EN10210, SY/T5768 -2006, GB/T3091 -2008, GB/T9711 -1, JIS G3444, JIS G3452 etc.
Bangdong Pipeline Products ASTM/ASME A53/SA53 seamless and welded steel pipe is a general, all-purpose pipe used in generator plants, refineries, compressor stations, natural gas transmission, and steam conduction. It is acceptable for welding, flanging, and bending.
Our steel is locally sourced, developed and produced which means our customers are assured of the highest quality standards and a local, concerned customer service presence invested in the success of your project. Bangdong Pipeline has control over every step of the pipe manufacturing process, from melt to final product. We manufacture our tubular products at several C.N.-based facilities that produce high-quality tubular products with low-residuals in a wide range of strength levels with superior toughness.
A53 Comparative Specifications
ASTM Specification A53 covers seamless and welded, black and hot-dipped galvanized nominal (average) wall pipe for coiling, bending and other special purposes and is suitable for welding. Bangdong Pipeline Products does not produce galvanized pipe.

· Testing Requirements for seamless and welded API 53 steel pipe
o Hydrostatic Testing test pressures for plain and threaded and coupled pipe are specified. Hydrostatic pressure shall be maintained for not less than 5 seconds for all sizes of seamless and ERW pipe.
o Mechanical Tests:
§ Tensile Test: Two transverse tests required on the ERW for NPS 8 and larger, one across the weld and one opposite the weld.
§ Flattening Test: On ERW for NPS 2 and larger, STD and XS wall (not required for XXS pipe)
§ Bending Test (cold): For NPS 2 and under, XS wall and under; for NPS 1-1/4 and under, XXS wall
