JOINTING METHOD FOR COUPLINGS

Category

Ductile Iron Coupling

Step 1

Check the components – two part coupling and EPDM gasket, 2 x M8 bolts and nuts (up to 100 mm diameter ) 4 x M8 bolts and nuts (for 150mm diameter and above). Ensure the 2 grub screws for electrical continuity are present (shown below inserted into casting).

Ductile Iron Coupling

Part Nos:- HS2012, HS3012, HS4012, HS6012, HS8012, HD6012, HD8012

Step 2

Fit the gasket to the lower pipe/fitting first, line up the upper component and fit carefully into place. Make sure the two components are square and parallel and line up correctly with the gasket.

Step 3

Line up the two parts of the coupling ensuring they fit correctly over the gasket. At this point check that the two grub screws for electrical continuity do not protrude on the inside of the coupling.

Bracket Assembly

Step 4

Bolt the two parts of the coupling together and gradually tighten, ensuring an equal distance is maintained during assembly. Do not over tighten or tighten only one side at a time. We recommend the use of a torque wrench at 15Nm.

Bracket Tightening

Step 5

Adjust the grub screws until each is lightly touching the pipe then give them a final half turn. This normally will be adequate to allow metal to metal contact and provide electrical continuity – do not over tighten.

Rapid Connect Coupling

Step 1

Rapid connect pipe coupling supplied complete with EPDM gasket and electrical continuity provision

Bracket Fitting

Part Nos:- HDS2002, HS3002, HS4002, HS6002, HS8002

Step 2

Push the coupling onto the end of the pipe or fitting up to the gasket’s central register.

Bracket Fitting

Step 3

Push the next pipe or fitting into the coupling making sure that the cut pipes are square.

Pipe Fitting

Step 4

Tighten the set screw using;

6mm allen key /socket adaptor (50 – 150mm)

8mm allen key/socket adaptor (200mm)

Note: due to the block tightening feature the joint cannot be overtightened and this also ensures the sharp edges of coupling cut through the painted finish to provide electrical continuity
