Grooved Couplings
Grooved couplings are mechanical pipe connections that utilize grooves to interlock pipes. These couplings are widely employed in various grooved piping systems, including water supply, fire protection, HVAC, and process piping systems. The fundamental design of a grooved coupling comprises two grooved-end fittings with a gasket placed in between, which is secured using bolts or clamps. The grooves on the fittings are created by specialized machines cutting a groove at the end of each pipe. Subsequently, the groove is then filled with a gasket, and the two pipes are locked together by tightening bolts or clamps.
One significant advantage of grooved couplings is their ease of installation without the need for welding or threading, thereby reducing labor costs and minimizing downtime. Grooved couplings are also flexible and can absorb vibrations and pipe movements, which helps to reduce stress on piping systems. They provide a reliable and cost-effective solution for pipe connections and are suitable for a wide range of applications in commercial, industrial, and institutional environments, recognized for their durability, simple installation, and versatility.
