Female socket weld connection to allow for a smooth bore and better fluid flow
Stainless steel 304/304L for corrosion resistance
Class 3000 for high pressure applications
Forged for durability
Description This class 3000 stainless steel 304/304L union is a pipe fitting with female socket welds for extending and connecting pipes. The socket weld union has an internal recess on the inside diameter to allow for a smooth bore and better fluid flow. The class 3000 union is made of forged stainless steel 304/304L for durability and corrosion resistance. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure. This fitting meets standards ASTM A182, ASME SA182, and ANSI B16.11 for quality assurance. 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).
