Compared with traditional welding or flange connections, the grooved coupling has a faster installation speed and shorter construction period, reducing labor costs. The overall project cost is lower due to the reduction of on-site anti-corrosion treatment and welding processes. The large-diameter grooved coupling is widely used in fields such as long-distance water transmission networks in water conservancy and municipal integrated utility tunnels.
On-site installation does not require open flame operations, avoiding the fire risks associated with welding. The grooved connection method is free from welding slag and smoke pollution, making the construction process environmentally friendly.
The large-diameter grooved coupling uses a mechanical connection method, eliminating the need for on-site welding and completely solving the corrosion problem at the welding joints. This connection method can extend the on-site corrosion resistance service life from the traditional 20–30 years of welding to over 50 years. The surface of the pipe clamp can also be treated with anti-corrosion methods such as powder coating to further enhance its corrosion resistance.
The grooved coupling can achieve flexible connections of pipes, effectively solving leakage problems caused by pipe settlement, expansion, contraction, and thermal expansion and contraction. The flexible joint design allows pipes to move freely within a certain range, adapting to complex geological conditions such as soft foundations and seismic zones.
The installation is simple and quick, requiring only ordinary workers with wrenches to complete the process, without the need for professional welding skills. The coupling is easy to disassemble and assemble, allowing for convenient replacement of pipe fittings during maintenance, reducing maintenance time and costs. It is suitable for installation in confined spaces and occupies little space.
