Steel Pipe
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.

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
