Non-metallic expansion joint

When installing non-metallic expansion joints with compensators, the direction of the wear-resistant lining should be consistent with the pipeline flow. Non-metallic compensators should be equipped with fixed rods. After installation, mark them with a yellow rod or fixed rod for easy disassembly and ensure the compensator operates normally. **Caution:** When installing non-metallic compensators, ensure they are in a natural state rather than artificially deformed. During installation, if welding is involved, protect the compensator's insulation layer, especially the product surface that is prone to exposure to molten slag combustion. Although non-metallic compensating devices have strong thermal resistance, preventing fire from starting during installation is crucial.
