ABSTRACT:
The piping component is comprised in part of a metal housing that is positionable with a metal pipe. The metal housing forms an opening in which a piping component body is inserted. The body of the piping component can be fastened to the metal housing using an epoxy adhesive, a set screw connection, a threaded connection, press fit connection, a key connection or a pin connection or a combination of these connections. The body is comprised of plastic, which is less expensive than metal and facilitates forming, including machining or molding, while maintaining its structural integrity in a hostile fluid environment, such as in oil or gas. Piping components such as flowmeters, flow conditioners, small volume provers, static mixers, samplers, and valves are contemplated for use with these multiple materials.
