Descrição do produto

ASTM A106/A 106 M-08


especificação padrão para tubulação de aço de carbono sem costura para serviço de alta temperatura


Scope

Covers seamless carbon steel nominal wall pipe for high-temperature service, suitable for bending flanging and similar forming operations.

NPS 1-1/2" and under may be either hot finished or cold drawn. NPS 2" and larger shall be hot finished unless otherwise specified.







Process

Killed steel, with primary melting process being open-hearth, basic-oxygen, or electric-furnace, possible combined with separate degassing or refining.

Steel cast in ingots or strand cast is permissible.

Hot-finished pipe need not be heat treated.

Cold-drawn pipe shall be heat treated after the final cold draw pass.

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

Weight of any length shall not vary more than 10% over and 3.5% under that specified.

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.
