Product Description

Seamless Or Welded Carbon Steel Pipe

Bangdong Supply Cold Drawing Seamless Pipe,Steel Run Pipe,Steel Straight Pipe.Seamless or welded carbon Steel Pipe as the outer backing layer, and corrosion-resistant alloy pipe as the inner corrosion layer, using the limit elasticity hydraulic composite method innovated independently by the company achieves the composite between the inner and outer pipe and forms the mechanical liner pipe. Through the composite technology, the optimal composite effect of mechanical liner can be achieved, and the shear stress between inside and outside metal layer can reach 2.0MPa (the relative standard requires 0.2-0.5MPa). Meanwhile, we develops specially the pipe ends automatic overlaying technology and NC machine tools specialized for beveling, which can process complex shape bevels such as U-bevel, and guarantees the conformity of pipe mouth diameter and bevel size, so as to operate pipe jointing on site.

Carbon steel pipe mainly have A106 Pipe and A53 Pipe , Please kindly check below details for their differences.

A106 Pipe

ASTM A106 pipe (also covered in ASME specifications as S/A 106) is the standard specification for seamless carbon steel pipe for high-temperature service. Most common uses are in refineries and plants when gasses or fluids are transported at high temperatures and pressures. Bangdong is a world leader in the supply of A106 / SA 106 pipe and stocks a full range of grades B/C in a size rage of NPS 1/8″ to NPS 48″, with nominal (average) wall thickness as given in ANSI B36.10. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification*. Pipe ordered under this specification shall be suitable for bending, for flanging, for welding, and for similar forming operations. A full range of A106 stock is available in Schedules 10 through 160, STD, XS, XXS. Unscheduled wall thicknesses available up to 4 inches.

Bangdong stocks a full range of A106 seamless carbon steel pipe.

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.

· 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
