application
- Pipeline Renovation Project: Different diameter internal and external thread design enables quick sealing and connection of new and old pipelines.
- Fire Protection System Maintenance: UL-certified variable diameter connection ensures high-pressure, leak-free renovation of sprinkler pipe networks.
- Ship Engine Room Maintenance: Quick repair connection of fuel/cooling water pipes with different diameters in confined spaces.
- Municipal Water Conservation Renovation: Water-saving connection of large-diameter main pipelines and old branch pipelines without welding.
- Industrial Equipment Integration: Eliminate flange connection leakage risks in compressor inlet/outlet pipes with different diameters.
- Agricultural Irrigation Upgrades: Rapidly extend main pipeline and branch pipeline connections with different diameters at pump stations.
- Mining Pipeline Emergency: High wear resistance to withstand impact in slurry transportation pipelines with different diameters.
- Chemical Instrument Installation: Micro-sized pipes with different diameters achieve seamless connection between instrument pipelines and main processes.
advantages
- Dual-thread high-pressure seal: 25 bar operating conditions with BSPT tapered threads ensure zero leakage in both directions.
- NSF safety certification: Specific models feature a zinc-plated layer for drinking water applications, eliminating the risk of heavy metal leaching.
- Compact variable-diameter design: The integrated internal and external thread design saves 70% installation space compared to traditional components.
- Fluid-Friendly Transition: Conical flow channels reduce pressure loss in the reducer section to one-quarter of traditional structures.
- Armor-Grade Dual Protection System: Hot-dip galvanized coating passes 3,600-hour industrial acid/alkali and salt spray dual testing.
- Enhanced vibration resistance: Thickened eccentric wall design improves mechanical impact resistance by 45%.
- Installation efficiency boost: Single-piece replacement of union fittings and double pipe clamps saves 85% of installation time.
- Precision size coverage: 1/4“ to 2” diameter range accommodates modifications from instrumentation microtubes to industrial main pipelines.
packing
- Asymmetric Cushioning System: EPE pearl cotton molded uneven curved surface adaptive wrapping.
- Anti-corrosion armor layer: vapor-phase anti-corrosion film + moisture-proof aluminum foil vacuum composite sealing.
- Anti-misalignment positioning structure: laser-cut pine wood irregular track-style slots for precise fitting.
- Heavy-duty load-bearing solution: steel-reinforced fumigated wooden box (compatible with DN50 load-bearing capacity).
- Zero-displacement design: inner box cross steel frame locking tube clamps for transportation stability.
