ASME B16.9 is the standard of factory made wrought buttwelding fittings that inlcudes elbow, tee, reducer, cross, cap and stub end. All of them are manufactured by steel pipes and plates, the pipes could be seamless and welded types. They are mostly used for pressure piping applications. Our butt weld 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 ASME B16.9 buttwelding fittings suppliers in the industry.

Advantage of ASME B16.9 Buttweld Fittings
Butt welding pipe fittings offer many advantages compared to threaded fittings and socket weld fittings. The later are only available up to 4-inch nominal size whereas butt weld fittings are available in sizes from ½” to 80”.
Benefits
- Butt welded joint is permanently sealed and powerful.
- The butt welding pipe fittings have a lower cost in bugdet.
- The butt welded joints have a smaller space in the system.
- Continuous steel structure of the joints between the pipes and fittings have a good strength in the piping system.
- Butt welding pipe fittings usually has a smooth surface and the direction of gradual change, it will reduce the pressure loss and turbulence of the system,and protect from the corrosion and erosion.
