What is Buttweld Fittings

Buttweld pipe fittings comprises of long radius elbow, concentric reducer, eccentric reducers and Tees etc. Butt weld stainless steel and carbon steel fittings are an important part of industrial piping system to change direction, branch off or to mechanically join equipment to the system. Buttweld fittings are sold in nominal pipe sizes with specified pipe schedule. BW fitting’s dimensions and tolerances are defined as per ASME standard B16.9.

Butt welded 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 72”. Some of the benefits of weld fittings are; 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.

Why Use Buttweld Fittings?

Buttweld fittings can withstand pressures and temperatures in very harsh environments. They are generally considered to be the most robust welding fixture, no matter what industry it is required for. However, they do take a considerable time to fit and a highly skilled installer is required to weld them correctly on site.

– Welded connection offers a more robust, a stronger and a more leak-proof piping connections.
– The nature of the continuous metal structure provides added strength to the overall piping system.
– The smooth inner surface and gradual directional changes provide a seamless flow, thus minimising pressure drops and turbulence inside the pipe.
– Provide the option of various different turn radiuses due to the manufacture of Short Radius fittings, Long Radius fittings and 3R Elbows.
– They are cost effective compared to the counterpart fittings in the threaded or socket weld varieties.
– They have a long service life and are cost effective to purchase and deploy.
– Buttweld fittings can withstand corrosion and erosion more effectively than its socket weld and threaded equivalents.
– A welded system uses comparatively less space that the other alternatives
