Stainless Steel Elbow 90 & 45 Degree Elbow Stainless Steel Pipes and Fittings
Stainless steel elbow have 45 and 90 degree which a common used type in the industries, it is produced by steel rod and pipes, the manufacturing standard are ASME B16.9 and ASME B16.11. 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 stainless steel pipe elbow fitting suppliers in the industry.

Manufacturing Technical of Stainless Steel Fittings
Stainless steel butt welding fittings can be into 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.
Forged stainless steel fittings can be divided into socket weld fittings and threaded pipe fittings, both types are forged by steel rod which according to ASME B16.11
Standard of 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.
