ASTM A672 Grade B50 Electric Fusion Welded Steel Pipe For High Pressure Service
ASTM A672 Grade B50 Electric Fusion Welded Steel Pipe for High Pressure Service
The A672 pipe specification covers electrofusion-welded steel tubing with added filler metals, made from pressure vessel quality plate of various analyses and strength grades for high pressure service at atmospheric pressure and lower temperatures. Heat treatment may or may not be required to achieve desired properties or to meet applicable code requirements. Supplemental requirements are available when additional testing or inspection is required.
ASTM A672 pipe specifications typically include pipe with an outside diameter of 16 inches (405 mm) or greater and a wall thickness of 1/4 inch (6.4 mm) or greater. Other pipe sizes are available, provided all other requirements of this specification are met.
