application
- Cross-material pipe connections: For use in mixed connection systems between HDPE plastic pipes and steel/cast iron pipes, such as chemical plant renovations or upgrading of municipal pipelines, or expanding irrigation systems.
- Connection between new and old pipes: Serves as a transition layer to help prevent the need for entire piping system replacements, which can be costly and time-consuming.
- Highly corrosive application areas: ideal for highly corrosive environments of wastewater treatment plants, the coastal plants, using HDPE as a top and bottom section due to its corrosion resistance with metal section in central parts for pressure containment.
- Common mainstream pipe diameter support: Allows the pipe diameter to be converted from 2 inches to 10 inches (DN50-DN250) without any problem with the engineering.
avantages
1. Zero-leakage connection between dissimilar materials: A special sealing structure addresses the difference in thermal expansion rates between plastic and metal, completely preventing water and chemical medium leakage.
2. Dual corrosion protection: HDPE end resistant to acids and alkalis + metal end with anti-rust coating, suitable for highly corrosive environments, extending service life by 3 times.
3. Time-saving and labor-saving installation: No professional welding required; mechanical bolt fastening is sufficient, reducing construction difficulty and costs.
4. Earthquake-resistant and anti-disconnection: Flexible design cushions foundation settlement or vibration stress, preventing joint loosening or rupture.
5. One joint for multiple uses: Compatible with standard HDPE pipes (flat ends) and steel pipes (grooved ends) from different manufacturers, reducing the variety of spare parts required.
6. Ultra-long maintenance-free: Material designed to match the lifespan of the pipeline, requiring no maintenance for 20 years when buried underground.
emballage
- Dual-end differentiated protection:
- The HDPE interface side is fully covered with soft foam, and the metal groove end is reinforced with hard corner guards to prevent transportation impacts.
- The outer box is clearly labeled: HDPE-to-steel joint, 6 inches × 150 mm, with an installation diagram included.
- Large-size reinforced packaging:
- For sizes 6 inches and above, a split wooden box is used to isolate and protect the two ends with irregular structures.
- Moisture-proof maritime transport solution:
- Vacuum-sealed film + desiccant, with pallet wrap film fully covering the package, suitable for the humid conditions of long-distance maritime transport.
