application
- Equipment Port Extension Connections: Standard-length extension connections between industrial equipment ports and pipelines.
- Instrument Measurement Pipeline Installation: Convenient connections between pressure gauges/sensors and main pipelines.
- Water Treatment System Retrofit: Quick-seal connectors between filtration equipment and water supply pipelines.
- Ship Equipment Pipeline Adaptation: Corrosion-resistant threaded connections between engine room equipment and deck pipelines.
- Agricultural irrigation system upgrades: Efficient extended interfaces between pump house equipment and field piping networks.
- Laboratory precision piping: Reliable transition connections between instrumentation equipment and micro-piping.
- Energy station valve group connections: Pressure-resistant extended interfaces between control valve groups and conveying pipelines.
- Fire protection equipment rapid deployment: Emergency extended solutions between fire hydrants and water supply pipelines.
advantages
- Hexagonal quick installation: The external hexagonal design supports quick tightening with a wrench.
- Precision thread sealing: High-precision threads ensure long-term zero leakage at the interface.
- High-pressure dynamic sealing: Maintains connection stability and sealing under extreme conditions.
- Corrosion Resistance in All Environments: Thickened galvanized coating resists chemical medium corrosion.
- Wide Size Coverage: Fully compatible with micro-precision tubes to large industrial tubes.
- Thermal Deformation Resistance: Maintains material structural stability under extreme temperature changes.
- Vibration-Resistant Design: Special thread locking mechanism prevents interface displacement.
- Lifetime Maintenance-Free Commitment: Optimized processes significantly extend the service life cycle.
packing
- Hexagonal head protective sleeve: Custom PE protective cover wraps around the external hexagonal head to prevent damage.
- Double protection for threaded ends: Screw cap + foam ring composite protection for both ends of the thread.
- Scratch-resistant full coverage: Bubble column bag completely covers the joint surface.
- Smart size-specific positioning: Honeycomb cardboard compartments are categorized and secured by size.
- Clear specification labeling: Outer boxes are printed with corresponding size parameters and pressure ratings.
- Load-bearing grading scheme: Small-sized paper boxes/large-sized reinforced wooden boxes are packed separately.
- Full-process traceability system: Laser engraving + smart QR codes for dual traceability.
- Warehouse stacking optimization: Box body recessed structure supports three-dimensional dense storage.
