application
- Building water supply and drainage pipeline connection: Quick seal connection between water pipes of the same specification and equipment interface.
- Fire system pipeline extension: seamlessly connect the fire main and sprinkler branch extension pipeline.
- HVAC pipe network transformation: connect chilled water pipelines to terminal equipment interfaces.
- Industrial equipment pipeline docking: compressor/reactor and other equipment are quickly connected to the conveying pipeline.
- Ship piping system maintenance: Corrosion-resistant connections between deck piping and engine room equipment.
- Municipal pipe network repair project: repair the damaged pipe section of the water supply/gas supply pipeline with pressure.
- Agricultural irrigation system upgrade: Transition joints connecting irrigation pipes of different materials.
- Energy Transmission Pipeline Connection: Reliable sealed connection of oil and gas transmission pipelines.
advantages
- Quick socket installation: The buckle design realizes the connection of pipes in seconds.
- High-pressure sealing performance: The reinforced structure ensures zero leakage under extreme pressure conditions.
- All-environment anti-corrosion: The internal and external galvanized layer resists water vapor/chemical media attack.
- Wide diameter adaptation: comprehensive coverage of small-size precision pipes to large-size industrial pipes.
- Anti-vibration design: Special thread locking mechanism prevents loosening and falling off.
- Bidirectional fluid compatibility: suitable for liquid/gas multi-media conveyance.
- Extreme Temperature Resistance: Maintains seal stability in severe cold and high temperature environments.
- Lifetime maintenance-free: Optimized structure significantly reduces the frequency of replacement and repair.
packing
- Threaded double protection: PE screw cap + foam ring composite protection for socket joints.
- Pipe body seismic protection: Customized bubble column bags completely cover the pipe body to prevent scratches.
- Intelligent sorting and packing: Classified by diameter and embedded in honeycomb cardboard positioning slots.
- Visual identification box: Transparent window design for intuitive display of specifications and models.
- Load-bearing graded packaging: Small-diameter paper boxes/large-diameter reinforced wooden boxes for separate packaging.
- Marine-grade moisture-proof treatment: Moisture absorbers placed inside the box and sealed with a waterproof membrane.
- Full-process traceability labels: Laser engraving on the pipe body + QR code traceability on the outer box.
- Stack-optimized design: Box body recessed structure enables ultra-high stacking in warehouses.
