From Pennsylvania Machine Works, a flanged nipple outlet is a type of integrally reinforced branch connection that combines three basic fittings: a flange, a nipple and an outlet. This advantage creates a smooth transition that improves internal flow. The outlet develops height consistency and reduces welding, labor, material test reports and inventory. The outlet portion follows ASME piping codes and properly reinforces the opening in the header pipe while the flange portion is in compliance with ASME B16.5.
