- Monolithic Isolation Joints are completely assembled and sealed at the factory and should not to be disassembled for installation.
- Inspect bore for foreign particles and clean if necessary.
- Install by butt-welding each end of the factory assembled joint to attaching pipe or fitting.
- No additional heat sink is normally required.
- Each joint is coated with non-conductive epoxy paint. This coating should remain on the product to insure the insulating capability of the joint.
- The Insulating Joint is factory tested for electrical resistance prior to shipment.
- If the original coating is removed or if an additional coating is to be applied, it is the responsibility of the user to assure that the joint remains non-conducting.
