ASTM A106 GR. A / GR. B / GR. C Seamless Carbon Steel Pipes

ASTM A106 Seamless Pressure Pipe (also known as ASME SA106 pipe) is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gasses that exhibit higher temperatures and pressure levels.

This specification covers seamless carbon steel pipe for high-temperature service

Sizes (Seamless): 1/2” NB - 60” NB
Sizes (ERW): 1/2” NB - 24” NB

Sizes (SAW): 16” NB - 100” NB  

Wall Thickness available:
Schedule 20 - Schedule XXS (heavier on request) up to 250 mm thk.

For each reduction of 0.01% carbon below 0.30%, an increase of 0.05% manganese above 1.06% would be permitted to a maximum of 1.35% manganese.

When Grade 6 is ordered under this specification, supplying an alloy grade that specifically requires the addition of any element other than those listed for the ordered grade is not permitted. However, the addition of elements required for the deoxidation of the steel is permitted.

Permissible Variations in Wall Thickness

The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified.

Permissible Variations in Weights per Foot

NOTE -- NPS 4 and smaller -- weighed in lots. Larger sizes shall be weighed separately by length.

Hydrostatic Testing

Inspection test pressures produce a stress in the pipe wall equal to 60% of specified minimum yield strength (SMYS) at room temperature. Maximum Pressures are not to exceed 2500 psi for NPS3 and under 2800 psi for the larger sizes. Pressure is maintained for not less than 5 seconds.Mechanical
Tests Specified

Tensile Test -- NPS 8 and larger -- either transverse or longitudinal acceptable

Smaller than NPS 8 -- weighed in lots. Larger sizes -- by length.

Flattening Test -- NPS 2-1/2 and larger.

Bending Test (Cold) -- NPS 2 and under.
