Grooved coupling consists of a housing, gasket, and fasteners to create a groove-based leak-tight structure. A quick rigid grooved coupling, however, is designed to prevent movement through grip teeth in the housing, allowing for faster installation.
The quick Yinuo-type rigid coupling is specifically used for grooved pipeline connections. At the pipe joint, the adjacent pipe ends are restricted from relative angular displacement and axial rotation.
The rubber gasket used in these systems is flexible, helping to reduce noise and mitigate vibration. Its highly elastic sealing ring absorbs vibration and noise, effectively reducing their transmission.
Grooved flexible joints also eliminate equipment misalignment errors, reduce stress on pumps and equipment connections, and accommodate both linear and angular deflection in piping systems.
The grooved tube card has a unique structure that presses the sealing gasket tightly against the pipe while enhancing joint strength. The housing, made of ductile iron, further helps absorb noise.
The grooved connection system can be installed up to 10 times faster than conventional methods like welding, threading, or soldering.
Welding comes with various hazards, including welding arcs, compressed gas exposure, toxic fumes, and risks to personal safety, such as injuries to the eyes, hands, feet, and body. The grooved connection system eliminates these safety risks. Installation requires only a wrench, making it ideal for confined spaces.
In cases where a mismatch occurs during flange welding, rework involves complex cutting and re-welding processes. In contrast, the grooved connection system allows for 360-degree adjustment of components before final fixing, significantly reducing rework time and associated costs, thus improving efficiency.
