Product Description


As we know ASTM A106 Grade B pipe is one of the most popular seamless steel pipes applied in different industries. Not only in pipeline systems like oil and gas, water, mineral slurry transmission, but also for boiler, construction, structural purposes.

So what is ASTM A106 Grade B pipe and why it is required so a large quantities in different industrial activities?

As below we will introduce all the details for ASTM A106 B pipe from different aspects.

  • Standard definition
  • Dimensions
  • Material specification
  • Standards referred for making A106 pipes
  • Grade types
  • Chemical composition
  • Mechanical Strength

A Specific order description

ASTM A106 Standard Specification

  • ASTM A106 is the standard specification for seamless carbon steel pipe applied for high temperature services.
  • Here you could find ASTM A106 standard specification in PDF.
  • ASTM A106 Grade B Seamless 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.
  • Raw materials
  • The materials used for ASTM A106 standard specification shall be applicable for bending, flanging, or the similar forming processes. In case the steel material is to be welded, the welding process supposed to be suitable for this grade of ASTM A106, and applicable for the high temperature working environment.
  • Where there is a superior or a higher grade for the ASTM A106 steel pipe is required, the standard has a optional specification for the supplementary requirements, for the pipes that used this standard. More over, these supplementary specification asked for the additional test, when the order is to be placed.
  • Standards referred for making ASTM A106 pipes

Surface standard:

  • SSPC-SP 6 The standard specification for the surface.

Grade B Seamless Pipe

  • ASTM A106 standard specifications for the seamless steel pipe have three grades, that is ASTM A106 Gr. A, Grade. B and C, with the higher grade material, the strength performance is better.

Test Methods

  • The test methods for the ASTM A106 A, B, C are the flattening tests, hydrostatic test, nondestructive electric test, Ultrasonic test, eddy current test, flux leakage test, these test procedures shall be notified or discussed with client to confirm what kind of test will be applied.

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

Tensile Strength, min, psi [MPa] Grade A 48,000 [330], Grade B 60,000 [415], Grade C 70,000 [485]
Yield Strength minimum at psi [MPa] Grade A 30,000 [205], B 35,000 [240], C 40,000 [275]

Elongation in 2 in (50mm), minimum percentage % , For all small sizes tested in full section, basic minimum elongation transverse trip tests: Grade A Longitudinal 35, Transverse 25; B 30, 16.5; C 30, 16.5; In case standard round 2 inch gage length test sample is used, above values are: Grade A 28, 20; B 22, 12; C 20, 12.
