Read installation instructions rst before installing. Check parts to ensure that no damage has occurred during transit and that no

parts are missing. Also check the diameter of the pipe and the range marked on the clamp to ensure you have the proper size.

Style SCC

Full Circumferential Repair Clamp

Step 1 • Check the Clamp parts to insure that no dam-

age has occurred during transit and that no parts are missing.
Also check the diameter of the pipe and the size marked on
the clamp to insure you have the proper size. Thoroughly
clean pipe surface that will be covered by the clamp. A suit­able gasket lubricant should be used on rough surface pipe
to assure proper seal.

Step 2 • Place reference marks on the pipe in line with

the crack or hole in the pipe, slightly wider than the clamp.

Step 3 • Wrap gasket cartridge around pipe.

Step 5 • Snap bolts into place on top of receiver

lugs. Make sure the gasket has seated itself at onto the
pipe face. Tighten nuts nger tight. Rotate clamp into
position and center the bolts over the crack or hole being
repaired (check reference marks).

Step 6 • Tighten all nuts evenly in 10 ft-lb. increments.

Keep torques as evenly balanced as possible. Use a wrench
with at least a 12" handle.

Step 4 • Back off nuts of shell to the end of the bolt,

DO NOT REMOVE. Separate clamp and wrap it around the

gasket cartridge, positioning it so the locating bumps are be­tween the lugs (in the shell gap).

Note: If necessary (because of water pressure) Step 4 and
Step 5 can be performed beside the pipe break. Slide the
clamp over the break after the bolt head has been snapped
in place.

Note:

25 ft-lbs. torque =
12" wrench
w/25 lbs. force

Torque Recommendation

20-25 ft-lbs. Max.

For best results, wait 10 minutes and then re-tighten
to proper torque.

PRECAUTIONS

1. Check diameter of pipe to make sure you are using the correct size clamp.

2. Clean pipe to remove dirt and corrosion from the surface.

3. Place marks on the pipe to reference the leak. Use these marks to assure that the clamp is properly

positioned.

4. Make sure no foreign materials stick to the gasket as it is brought around the pipe, nor become

lodged between gasket and pipe as nuts are tightened.

5. Avoid loose tting wrenches, or wrenches too short to achieve proper torque.

6. Keep threads free of foreign material to facilitate tightening.

7. Bolts are often not tightened enough when a torque wrench is not used. Take extra care in this situation

to make sure proper tightening occurs. Do not exceed 25-ft-lbs.

8. Pressure test for leaks before backlling.

9. Backll and compact carefully around clamp.

10. When reinstalling parts with stainless steel hardware there may be a loss in pressure holding ability due

to worn or damaged threads during the original installation.

COMMON INSTALLATION PROBLEMS

1. Bolts are not tightened to the proper torque.

2. Bolt torque is in excess of 25 ft-lbs.

3. Rocks or debris between pipe and gasket.

4. Dirt on threads of bolts or nuts.

5. Repair clamp too small for the size of damage to pipe.

6. Repair clamp not centered over damaged portion of pipe.

7. Repair clamps should not be used as couplings.
