The Merit Brass weld neck flange is a schedule 40 class 150 stainless steel 304/304L pipe fitting used to join two sections of a piping system. This weld neck flange has a beveled hub for butt-welding to the mating pipe and bolt holes for connecting to flat surfaces or other flanges. Made of stainless steel 304L, the lower carbon content of this fitting minimizes harmful carbide precipitation due to welding, ensuring corrosion resistance. This class 150 fitting meets steel 304 strength standards, 304L extra-low carbon standards, and specifications ASTM A182, ASME SA182, and ANSI B16.5 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.
