Pipe Connections
(Mile Steel, Carbon Steel, Stainless Steel)
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 sched-ule. 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″.
