Installation Method
- Clean and prepare the pipeline surface before installation.
- Position the heat shrink sleeve around the pipeline joint or repair area.
- Apply heat evenly along the sleeve using a suitable heat source.
- Allow the sleeve to shrink tightly around the pipeline while adhesive flows to seal the surface.
- Ensure both ends of the sleeve form complete seals against the pipe coating.
