ASME B16.9 | Equal Buttweld Cross | Pipe Cross Fittings | NPS 1/2″–48″ | Carbon Steel, Stainless Steel, Duplex, Alloy & Nickel Alloys
Elite Equal Crosses are factory-made butt-welding pipe fittings used to create a four-way piping connection. All four outlets are the same nominal size, providing a symmetrical flow path for process piping and distribution systems.
Equal Crosses are manufactured in accordance with ASME B16.9 where applicable, which covers dimensions, tolerances, ratings, testing and marking for factory-made wrought buttwelding fittings from NPS 1/2 through NPS 48.
