Stainless Steel Pipe Fittings Suppliers SS Weld fittings & SS Tube Fittings
Top suppliers of stainless steel pipe fittings choose the original material from big steel mill, then produce ASME B16.11 fittings by SS rods and ASME B16.9 fittings by steel pipes. They are mostly used for pressure piping applications. Our stainless steel pipe fittings limit types of localized corrosion and are indispensable to applicatons requiring compact but flexible seals. Restraining deformities and cracks under high temperatures.
Zizi Engineering is one of the top manufacturer, exporter and supplier of steel pipe fittings & flanges which are available in various sizes, dimension and shapes according to our client’s requirement. We are at the forefront of innocation in both product lines and after seals services. That's why we constantly upgrade our pipe fittings and services to meet market expecations and demands, We re reputed as an execllent quality ss pipe fittings suppliers in the industry.

Type of SS Pipe Fittings
Stainless steel butt welding fittings are including bends, elbows, reducers, tees, caps, cross and stub end.They can be seamless and ERW pipe fittings, seamless fittings are made from seamless steel pipes, ERW fittings are made by ERW steel pipes while welded large diameter fittings are produced by steel plates.Both of them are manufactured according to ASME B16.9.
Stainless steel forged fittings can be divided into socket weld fittings and threaded fittings, these are elbows, tees, caps, crosses, union, coupling, bushing, nipples, swaged, plug and olets. All of them are forged by steel rod which according to ASME B16.11
Standard of Sanitary Stainless Steel Pipe Fittings
ASME B16.9 Standard covers overall dimensions, tolerances, ratings, testing, and markings for factory-made wrought buttwelding fittings in sizes NPS 1 ∕ 2 through NPS 48 (DN 15 through DN 1200). It covers fittings of any producible wall thickness. This standard does not cover low pressure corrosion resistant buttwelding fittings.
ASME B16.11 Standard covers ratings, dimensions, tolerances, marking and material requirements for socket-welding and threaded forged fittings. These fittings are designated as Class 2000, 3000, and 6000 for threaded end fittings and Class 3000, 6000, and 9000 for socket-weld end fittings.
