Installation Instructions

Dismantling Joint installation guide

Before beginning assembly of your Robar Dismantling Joint
be sure to confirm that you have received the correct size
required and all parts have not been damaged during
transport.
1. Inspect all mating flange surfaces for any damage or irregularities
that may interfere with the flanges ability to form a long term seal.
2. Measure the pipe flange for parallelness. As well confirm that the
drill pattern on the Robar dismantling joint matches the mating
flanges.
3. Measure the gap to determine the distance required and confirm
the dismantling joints capability (max 2").
4. Make sure that the inserted spool piece is inserted at least 2
inches inside of the flanged coupling body.
5. Loosen the coupling bolts on the end ring to "relax" the gasket
seal and to allow for easy movement of the flanged spigot. Total
disassembly of the dismantling joint is not required for installation
(ties rods must be removed for installation).
6. Move the dismantling joint into position between the mating
flanges.
7. Using flange bolts, fasten the flanged coupling end of the
dismantling joint to one of the mating flanges (flange gasket not
required for 7400 or 7500 series dismantling joint). Depending on
the situation it maybe necessary to insert the tie rods concurrently
with the flange bolts.
