Stainless steel pipe reducer have concentric & eccentric types, both of them are made from seamless pipes or steel plates, the common grades are ASTM A403 WP 304, WP316, WP321 and WP310S. 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 ASTM A403 stainless steel pipe fittings suppliers in the industry.
