316 Stainless steel threaded pipe fittings are manufactured by forging and machining solid steel and are available in a multitude of shapes like elbow, tee, cross, union, cap,coupling. There are many types of elbows that are 90 & 45 degree, straight & reducing elbow, F/Female & F/Male thread. They are also belong to high pressure pipe fittings because their pressure ratings are 2000lb, 3000lb, 6000lb.
Threaded pipe fittings are used only in conjunction with ASME Pipe and are available in the same size range. And where pipe-work is permanent and are designed to provide good flow characteristics. And suitable in small bore pipes and piping system.
