Product Description

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.
