ASTM A106 pipe (also covered in ASME specifications as S/A 106) is the standard specification for seamless carbon steel pipe for high-temperature service. Most common uses are in refineries and plants when gasses or fluids are transported at high temperatures and pressures.
A106 PIPE SPECIFICATIONS
NPS 1/4″- 30″
Schedules 10 through 160, STD, XH and XXH
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.
Dinesh Tube India stocks a full range of A106 pipe (SA106 Pipe) in:
- Grades B and C
- NPS ¼” to 30” diameter
- Schedules 10 through 160, STD, XH and XXH
- 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.
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.
