Victaulic Introduces Rigid and Flexible High-Pressure Couplings for Large-Diameter Piping Systems

Style 207 and Style 277 couplings ideal for large-diameter abrasive piping systems

EASTON, PA - Victaulic, the world's leading manufacturer of mechanical pipe joining systems, introduces the Style 207 and Style 277 high-pressure couplings for large-diameter systems. The couplings maximize the life of piping systems for abrasive services such as oilsands, slurries and tailings, while offering a cost-effective joining method with superior performance benefits.

Style 207 and Style 277 couplings extend the life of piping systems by maintaining full pipe-wall thickness and a smooth flow path. A specially designed ring is butt welded to the end of the pipe, and the coupling is assembled on the ring to complete the joint. The couplings' FlushSeal gaskets have a center lip that creates a barrier between the pipe ends, ensuring a smooth flow path and allowing the couplings to be used on lined pipe. In addition, the couplings allow the pipe to be easily rotated, further extending the life of the system.

Style 207 and Style 277 couplings offer multiple performance benefits that a typical welded joint cannot match. First and foremost, the coupling is available in two designs: the rigid Style 207 coupling, which maintains a movement-free joint, and the flexible style 277 coupling, which features deflection capabilities that can assist in routing pipe over uneven surfaces. Both styles feature a unique, patented wedge-shaped groove profile that helps align the coupling in the groove, resulting in easier initial assembly. Furthermore, the pipe can be lifted into place with the couplings already assembled because the coupling is stronger than the pipe.

Style 207 and Style 277 couplings are comprised of two ductile iron housings, which are connected with four bolts. The couplings are available with silicone gaskets for a variety of chemical services, and EPDM gaskets for water services. The couplings provide a strong connection for large-diameter piping systems with working pressures up to 650 psi (4500 kPa), and are available in 26, 28, 30, 32 and 36-inch sizes (650, 700, 750, 800 and 900 millimeters).
