This Reference Catalog identifies stainless steel pipe couplings and other pipe fittings through specification charts and illustrations. Please view these theoretical bursting pressures for various stainless steel pipe. A coupling connects two pieces of pipe together. 150 lb cast couplings can come threaded or socket weld. If the two pipes being connected are not the same size, one would use a cast reducing coupling. Couplings are one of the most common pipe fittings and available in a variety of different alloys.
