By certification 
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.
GNEE 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
