A106 PIPE SPECIFICATIONS

A/SA106
NPS 1/4″- 30″
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 gases that exhibit higher temperatures and pressure levels.
Chinese Products stocks a full range of A106 pipe (SA106 Pipe) in:
  • Grades B and C
  • NPS ¼" to 30" diameter
  • Schedules 20 through XXH
  • Wall Thickness beyond XXH, including:
    - Up to 4" wall in 20" through 24" OD
    - Up to 3" wall in 10" through 18" OD
    - Up to 2" wall in 4" through 8" OD
A/SA 106 Grade B specs are listed below. If you're looking for Grade B-specific product offerings.

Scope

ASTM A106 Seamless Pressure Pipe (also known as ASME SA106 pipe) 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.
Looking for specific post-production services? 

Process

Killed steel, with primary melting process being open-hearth, basic-oxygen, or electric-furnace, possibly 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.
