DN6 Buttweld Pipe Fittings

ASTM A420 WPL6 Buttweld Pipe Fittings Low Temp Carbon Steel Fittings Grade


We make low temperature carbon steel (LTCS) ASTM 420 WPL6 Buttweld Pipe Fittings from seamless and welded pipes, that is according to the standard of ANSI / ASME B16.9. They are mostly used for pressure piping applications. Our LTCS 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 low temp carbon steel buttwelding fittings suppliers in the industry.

Advantage of LTCS Butt Welding Fittings


Butt welding pipe fittings such as carbon steel and stainless steel offer many advantages compared to threaded and socketweld fittings. The later are only available up to 4-inch nominal size whereas butt weld fittings are available in sizes from ½” to 80”. 


Welded connection offers more robust connection
Continuous metal structure adds to the strength of the piping system
Butt-weld fittings with matching pipe schedules, offers seamless flow inside the pipe. A full penetration weld and properly fitted LR 90 Elbow, Reducer, Concentric reducer etc. offers gradual transition via welded pipe fitting.
