6. Instanllation Instruction for Riquid & Flexible Coupling
1. Pipe preparation: Check pipe end for proper grove demensions and assure that pipe end is free of indentations and projections that would prevent proper sealing.
2. Lubricate gasket: Check gasket to be sure it's compatible for the intended service. Apply thin lubricant to the outside and seal lips of the gasket.
3. Gasket installation: Slip the gasket over one pipe, making sure the gasket lip does not overhang the pipe end.
4. Alignment: After aligning two pipe ends toghther, pull the gasket into position, centering between the grooves on each pipe. The gasket should not extend into the groove on either pipe.
5. Housing installation: Remove one bolt&nut and loosen the other nut. Place one housing over the gasket, making sure the housing fit into the pipe grrooves. Swing the other housing over the gasket and into the grooves on both pipes. Reinsert the bolt and connect two housing.
6. Tighten nuts: Firstly tighten nuts by hand and make sure oval neck bolt completely fits into bolt hole. Then securely tighten nuts alternatively and equally to specified bolt torque by using spanner.
7. Installation complete-rigid coupling: For rigid coupling, keep the gaps between bolt pads evenly spaced. Gaskets cannot be visual.
8. Installation complete-flexible coupling: For flexible coupling, two housing should be connected iron to iron. Gaskets cannot be visual.
Proper torquing of bolts is required to obtain specified performance. Over torquing the bolts may result in damage to the bolt and/or casting which could result in pipe joint separation. Under troquing the bolts may result in lower pressure retention capabilities, lower bend load capabilities, joint leakage and pipe joint separation. Pipe joint separation may result in significant property damange and serious injury.
