Which method is used to join a pipe with groove couplings?

The method used to join a pipe with groove couplings involves a specific combination of couplings, gaskets, and groove dimensions that are designed to work together effectively. This approach is critical because groove couplings rely on a mechanical connection that creates a tight seal without the need for additional materials like adhesives, screws, or welding.

When using groove couplings, the pipe ends are machined with grooves, and the coupling itself has complementary grooves that interlock with those on the pipe. Gaskets are then placed in these joints to ensure a watertight seal, which is essential for maintaining system integrity in pressurized applications. The listed combination ensures that the components are compatible and meet the required specifications for the intended application, providing the necessary strength and leak-proof integrity.

The other methods listed, such as welding techniques, screw joints, and adhesive bonding, do not apply to the groove coupling system. Each of these alternatives has distinct applications and limitations that do not align with the mechanical interlocking nature of groove couplings, highlighting why the combination method is the correct choice for joining pipes in this manner.
