Compared to traditional pipe connection methods, grooved pipe fittings offer several significant advantages:
Efficient and Simple Installation
No welding or secondary galvanizing is required; ordinary workers can perform the installation after minimal training. A single connection takes only minutes, drastically improving construction efficiency and shortening project timelines.
Safe, Eco-friendly, and Reliable
No open-flame work or welding slag pollution occurs on-site, eliminating risks such as electric shock or fire. They feature a self-tightening seal design where the sealing effect improves as internal pressure rises, supporting nominal pressures up to 2.5 MPa.
Preservation of Original Pipe Properties
Grooves are formed only on the outer surface, leaving the internal anti-corrosion coating intact. They are compatible with various pipe types-such as galvanized steel and plastic-lined steel pipes-without requiring secondary treatment.
Convenient and Flexible Maintenance
The piping system offers flexibility, providing resistance to vibration and thermal expansion/contraction, which enhances overall stability. Maintenance involves simply loosening the coupling to adjust or replace pipe sections; there is no need to damage surrounding walls, resulting in lower maintenance costs.
High Comprehensive Economic Value
Although the unit price of individual fittings is relatively high, the overall installation saves significant labor and time. The total installation cost is 30%–50% lower than that of flange connections, and projects can be put into service earlier to generate revenue.
