Pipe

Carbon Steel Pipe is manufactured and tested to ASTM specifications for use in mechanical and pressure applications but is also commonly used in structural applications.  Pipe is called out by a “nominal” inside diameter and a wall thickness (schedule 40, schedule 80, extra heavy, etc.)  The nominal size call-out references a fixed outside diameter while the exact inside diameter varies depending on the schedule of pipe.  Black pipe comes with a black lacquer coating and (along with uncoated pipe and galvanized pipe) is stocked in 21’ lengths.

ASTM A53 Grade A                        Tensile Strength (P.S.I) = 48,000                              Yield Point (P.S.I) = 30,000
