Weco wing unions are the most complete line of standard and sour gas pipe connections available, ranging in
size from 1- to 12-inches with cold working pressures to 20,000 psi. All Weco unions are color coded for quick identification. Materials meet ASTM and AISI standards.
Features & Benefits
Positive sealing designs: Weco wing union seals vary according to pressure and application. All provide positive, pressure-tight sealing.
Fast make-up and break-out: Three-lug nuts and rugged self-locking Acme threads provide fast make-up and break-out regardless of position or space restrictions. No special tools are required.
Interchangeable parts: All Weco parts of the same size, pressure rating, and figure number are interchangeable, making it easy to match male and female subs that are frequently
made-up and broken-out. Choice of end connections: Weco wing unions are available with line pipe or tubing
hreads, butt-weld or nonpressure seal end connections.
Nonpressure Seal Connection
The nonpressure seal option is especially designed for abrasive, high-pressure services where welded connections are undesirable. This design provides strong, permanent end connections without butt welding. The union ends are shop assembled to pipe or tubing. An epoxy thread-locking compound is used to secure the connection. All threads are isolated from the line fluid, and the smooth bore assures minimum turbulence, decreases washouts, and reduces chemical, acid, sand, or cement build-up around the pipe ends. Connecting threads are API round tubing threads for extra strength. Available in Figures 602, 1002, and 1502.
