Difference Between A671 and A672 EFW Pipes

A671 and A672 areEFW (Electric-Fusion Welded) Carbon Steel Pipes used for atmospheric and lower temperatures applications (A671) and high-pressure service at moderate temperatures (A672). As mentioned above, A671 is used for atmospheric and lower temperature application and A672 is used for high-pressure service applications at moderate temperature. However, if we compare the details e.g. A672 […]
