Description
Threaded Union
A Threaded Union is a mechanical pipe fitting designed to connect two sections of piping while allowing the connection to be conveniently assembled and disassembled. Unlike a permanently welded connection, a union provides a practical joining arrangement that can be separated when equipment maintenance, inspection, replacement, or piping modification is required. Threaded unions are used in a variety of industrial, commercial, utility, process, and mechanical piping systems where threaded connections are suitable for the operating conditions.
Masiva Metals supplies industrial piping components for different engineering and procurement requirements. A properly selected Threaded Union can help simplify piping assembly while providing a convenient connection point for maintenance. Material, size, thread configuration, pressure requirements, service temperature, process medium, and applicable project specifications should always be considered before selecting a threaded union.
