application
- Chemical Pipeline Repair: Rapidly seal corroded pipeline sections to restore emergency medium transportation.
- Fire Protection System Expansion: UL-certified threaded connections ensure high-pressure, leak-free extension of sprinkler networks.
- Ship Pipeline Maintenance: Rapid replacement and connection of damaged fuel/freshwater pipeline sections in engine rooms.
- Municipal Water Supply Renovation: Threaded direct connection of new and old galvanized steel pipes avoids welding-induced thermal deformation.
- Industrial Equipment Integration: Full-size sealed direct connections for reactor inlet/outlet pipelines.
- Mining Conveyance Network: High-wear-resistant pipe clamps resist vibration-induced loosening in slurry conveyance pipelines.
- Agricultural Irrigation Hub: Segmented rapid maintenance connections for main pipelines at pump stations.
- Energy Pipeline Network Upgrade: Leak-free extension and renovation of 6-inch large-diameter oil and gas pipelines.
advantages
- Dual-end high-pressure sealing: 25 bar operating conditions with BSPT tapered threads ensure zero leakage in both directions.
- NSF safety certification: Drinking water-grade galvanized coating (specific models) eliminates the risk of heavy metal leaching.
- Full Size Coverage: 1/4“ to 6” diameter to meet the needs of micro-instrumentation tubing to main pipelines.
- Armor-Grade Corrosion Resistance: Hot-dip galvanized coating resists 1,200 hours of salt spray corrosion from seawater/chemical media.
- Vibration-Resistant Structural Reinforcement: Thickened wall design improves mechanical impact resistance by 40% compared to standard parts.
- Installation Efficiency Revolution: Dual-threaded direct connection replaces flange assemblies, saving 90% of installation time.
- Wide Temperature Range Reliability: Maintains threaded seal integrity under extreme conditions from -30°C to 120°C.
- Heavy-Duty Diameter Assurance: 6-inch pipe clamps maintain zero deformation under 25 bar pressure.
packing
- Threaded Fortress Protection: Dual-end injection-molded cap nesting + silicone seal ring composite locking.
- Linear Buffering System: EPE pearl cotton molded tubular curved surface full wrap.
- Anti-rust Armor Layer: Vapor-phase anti-rust film + moisture-proof aluminum foil composite vacuum sealing.
- Precision error-proofing structure: Laser-cut pine wood track-style slots precisely fitted to dimensions.
- Heavy-duty load-bearing solution: I-beam steel frame fumigated wooden box (compatible with DN150 load-bearing capacity).
- Anti-rolling design: Inner box H-shaped steel rails locking tube clamps for zero-displacement transportation.
