11 02/18 FIELD CUTTING PIPE TO A SPECIFIC LENGTH Determine the exact length of carrier pipe needed. Mark the casing at this point. Measure back 3 1/2 inches on both sides and mark the casing at these points using a wrap-around. Use a carpenters handsaw or PVC saw to cut the PVC or HDPE casing. Remove the casing and cut off the insulation. Be careful not to damage steel carrier pipe during this operation. See illustration below. Mark, cut, and bevel the steel pipe at the desired length. Make sure cut is square and the bevel is approximately 15° and 3/4" long. Remove any burrs and ridges on the pipe. Using a utility knife, remove the insulation between the casing and the carrier pipe one inch in from the face of the casing as shown below. Insert the rubber end seal between the casing and the carrier pipe using the handle of a hammer or screwdriver to push the seal all the way. Silicone caulking may be used in lieu of the rubber end seal.
