ASTM A106 Grade B seamless pipes 20

ASTM A106/ASME SA106 is the standard specification for seamless carbon steel pipe applied for high temperature services. It includes three grades A, B and C, and common use grade is A106 Grade B. It used in different industries not only for pipeline systems like oil and gas, water, mineral slurry transmission, but also for boiler, construction, structural purposes.

ASTM A106 Grade B pipe is equivalent to ASTM A53 Grade B and API 5L B on chemical position and mechanical properties, in general use carbon steel and yiled strength minimum 240 MPa, tensile strength 415 Mpa.

Chemical Composition And Mechanical Strength

ASTM A106 Grade B and A pipe chemical composition

Please note:

For each reduction of 0.01% for maximum carbon element, an increase of 0.06% manganese above the specified value shall be permitted, and up to maximum of 1.35%.
Elements Cr, Cu, Mo, Ni, V combined shall not exceed 1%.

ASTM A106 Grade B Tensile Strength and Yield Strength

Elongation formula:
In 2 in. [50mm], shall be calculated by: e = 625 000 A^0.2 / U^0.9
For inch-pound Units, e = 1940 A^0.2 / U^0.9

ASTM A106 Grade B Pipe Dimensions Schedule

The standard covers pipe sizes in NPS (National Standard Straight) from 1/8 inch to 48 inch (10.3mm DN6 – 1219mm DN1200), meanwhile complied the nominal wall thickness of the standard ASME B 36.10M. For other sizes out of the ASME B 36.10M is also allowed to use this standard specification.

Large Diameter Seamless

My company can produce large diameter hot expansion seamless pipe. the diameter is from 20" to 40" , the seamless pipe length is from 5-12m. We stock more than 20,000 tons of seamless steel pipe on site to ensure your instant demand.  delivery is one week.

And more we can offer add-on services. If your large diameter seamless is in need of some extra work such as  pipe and tube cutting, heat treating, turning, boring, machining and welding attachment.
