Steel pipes connected with flexible grooved couplings offer high pull-out resistance, wide-angle deflection and significant axial movement, enabling simplified and rapid installation. This solution features broad pressure range compatibility and adapts to complex geological conditions such as soft/weak foundations, subsidence-prone areas, seismic zones and steep slopes. It extends pipeline service life and reduces replacement costs.

Steel pipes connected with rigid grooved couplings provide limited compensatory movement, effectively replacing traditional rigid connections (e.g., welding, flanges). This solution addresses stress issues caused by thermal expansion, installation misalignment, and operational loads, while eliminating the need for sliding supports and enhancing structural stability.

By using flexible couplings to connect valves or pipelines, this solution replaces traditional expansion joints, offering cost savings, maintenance-free operation, and vibration damping. The leak-proof design ensures high safety and reliability while enhancing installation efficiency.
