A672/A672M Standard Specification for Electrofusion Welded Steel Pipe for Medium Temperature and High Pressure Service.
The main difference between ASTM A672 and A106 is that A106 seamless steel pipe is a seamless carbon steel pipe used for high-pressure applications, while A672 electrofusion welded pipe is an electrofusion welded carbon steel pipe used for high-pressure applications at moderate temperatures.
What is the minimum wall thickness for ASTM A672 straight seam steel pipe?
The ASTM A672 pipe specification nominally covers 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.
