application
- End plugging of piping systems: permanent or temporary closure of open ports of water supply and drainage pipelines.
- Equipment maintenance isolation protection: seal the equipment interface during maintenance to prevent media leakage.
- Reserved interface of fire pipe network: seals the branch pipe port of the future expansion in the building fire protection system.
- Ship piping system protection: Closed deck pipe ports against marine salt spray.
- Industrial equipment pressure testing: Closed pipe ends for system tightness pressurization testing.
- Winter storage of agricultural irrigation systems: seal irrigation pipe network ports in winter to prevent frost cracking.
- Energy transmission pipeline maintenance: Block the isolation pipe section during oil and gas pipeline maintenance.
- Laboratory pipeline safety: seal the unused interface of the experimental gas pipeline.
advantages
- Groove-reinforced sealing: The recessed structure enhances the pressure-bearing capacity of the port seal.
- Quick-tightening seal: The standard thread design enables installation and removal in seconds.
- Extreme pressure protection: Maintains long-term zero-leakage sealing stability under high-pressure conditions.
- Full-environment corrosion resistance: Thickened galvanized coating resists chemical media and moisture corrosion.
- Wide size coverage: Fully compatible with micro-precision tubes to large industrial tubes.
- Impact-resistant structure: Reinforced groove design withstands external impact deformation.
- Temperature change adaptability: Maintains material structural integrity in extreme cold and high-temperature environments.
- Lifetime maintenance-free commitment: Special process significantly extends protective service life.
packing
- Groove-specific protective cover: Custom PE protective cover fits the curved surface of the groove to prevent scratches.
- Double protection for threaded ends: Screw cap + foam ring composite protection seals the thread.
- Individual impact protection: Bubble column bag completely covers the surface of the tube cap.
- Intelligent specification positioning: Honeycomb cardboard compartments are classified and fixed according to size.
- Visual specification identification: Transparent window on the outer box clearly displays the product size.
- Load-bearing Grading Solution: Small-sized vacuum-formed boxes/large-sized reinforced wooden boxes for separate packaging.
- Full-Process Traceability System: Laser engraving + smart QR code dual traceability.
- Warehouse Stacking Optimization: Boxes with embedded structures support ultra-high-density storage.
