Pipe ASME B36.10M BE SMLS Pipe API 5L /ASTM A106 A53 GR.B CS Pipe

ASTM A106/ASME SA106 is the standard specification for seamless carbon steel pipe used for high-temperature services. It includes three grades: A, B, and C, with Grade B being commonly used. This type of pipe finds applications in various industries, including pipeline systems for oil and gas, water, and mineral slurry transmission. It is also used in boiler systems and for construction and structural purposes.

ASTM A106 Grade B Pipe Dimensions Schedule

The standard covers pipe sizes in NPS (National Standard Straight) from 1/8 inch to 48 inches (10.3mm DN6 – 1219mm DN1200). It also complies with the nominal wall thickness specified in ASME B 36.10M. For sizes that are not covered by ASME B 36.10M, this standard specification can still be used.

Raw materials

The materials used for the ASTM A106 standard specification should be suitable for bending, flanging, or similar forming processes. If the steel material is to be welded, the welding process should be appropriate for this grade of ASTM A106 and suitable for high-temperature working environments.

In cases where a superior or higher grade of ASTM A106 steel pipe is required, the standard provides an optional specification for supplementary requirements. Additionally, these supplementary specifications require additional testing to be conducted when placing an order for pipes that adhere to this standard.

Grade B Seamless Pipe

The ASTM A106 standard specifications for seamless steel pipes consist of three grades: ASTM A106 Gr. A, Gr. B, and Gr. C. With higher-grade materials, the strength performance is improved.

Test Methods

The test methods for ASTM A106 grades A, B, and C include flattening tests, hydrostatic tests, nondestructive electric tests, ultrasonic tests, eddy current tests, and flux leakage tests. These test procedures should be communicated and confirmed with the client to determine which specific tests will be applied.
