application
- Fire Protection System Sealing and Reinforcement: Groove Locking Structure Ensures Long-Term Anti-Loosening of Sprinkler Pipe Network Flange Connections
- Ship Engine Room Piping: Anti-Vibration Design Solves the Risk of Fuel/Cooling Water Pipe Joint Loosening
- Industrial High-Pressure Equipment: High-Reliability Sealing and Locking Solution for Compressor/Reactor Flange Assemblies
- Maintenance of municipal valve assemblies: Quick repair solution for preventing loosening of main road valve sealing surfaces
- Energy transmission systems: Locking components for oil and gas pipeline flange connections that resist temperature difference deformation
- Agricultural irrigation hubs: Locking mechanisms for high-pressure pipelines in pump stations that prevent silt erosion
- Mining pipeline networks: Solutions for preventing loosening of flange sealing surfaces under high vibration conditions
- Chemical process equipment: Locking mechanisms for flange connections in corrosive environments that resist chemical medium erosion
avantages
- Anti-loosening structural design: Groove mechanical locking prevents thread retraction under vibration conditions.
- High-pressure sealing assurance: Compatible with BSPT tapered thread fittings to achieve 25 bar sealing conditions.
- Compact installation solution: Groove structure reduces installation space by 30% compared to traditional locking components.
- Tool Compatibility: Standard grooves compatible with standard wrenches for quick assembly and disassembly
- Wide Temperature Range Adaptability: Maintains locking force stability from -30°C to 120°C
- Full Size Range Coverage: DN15 to DN100 to meet requirements from miniature instruments to industrial main pipelines
emballage
- Scratch-resistant protection: PE foam tubing wrapped around the surface of the recessed structure.
- Layered isolation design: Honeycomb cardboard dividers prevent collisions during transport.
- Anti-rust treatment: Vacuum-sealed packaging with vapor phase corrosion inhibitor (VCI) paper.
- Anti-mixing structure: Laser-cut EVA inner lining with independent slots according to specifications.
- Bulk transport solution: High-strength corrugated cardboard box unitized packaging (compliant with ISTA 2A standard).
- Traceability management: Box QR codes linked to production batches and material reports
- Anti-loss design: Inner box self-sealing bags + tamper-proof labels ensure component integrity
