The Merit Brass welding spud flange is a class 150 stainless steel 316 cast pipe fitting with female National Pipe Taper (NPT) threads used to join two sections of a piping system. It has female NPT threads for connecting to male pipes and the flange is welded instead of bolted for a stronger seal. This welding spud is made of stainless steel 316, which is higher strength and more corrosion resistant than stainless steel 304. This class 150 fitting meets steel 316 strength standards and specifications ISO 49 and ANSI 1.20.1 for quality assurance. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure.
Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).
Merit Brass manufactures pipe nipples following ISO 9001 standards for quality assurance. The company, family-owned since 1937 and headquartered in Cleveland, OH, distributes pipe fittings in the United States and Canada.
