application
- Chemical system renovation: Different diameter pipe clamps seamlessly connect the pressure gradients at the inlet and outlet of the reaction device.
- Fire protection network upgrade: UL-certified variable diameter connections ensure high-pressure integration of multiple pipe specifications in sprinkler systems.
- Ship power maintenance: Zero leakage connections for fuel/cooling water pipes of different diameters in the engine room under vibration conditions.
- Municipal water supply optimization: Leak-free connections between large-diameter main pipes and old branch pipes in water-saving renovations.
- Industrial Equipment Integration: Eliminate turbulent energy loss in compressor inlet/outlet pipes with different diameters.
- Mining Conveyance Network: High-wear-resistant pipe clamps for different diameters resist impact wear in slurry pipeline sections with different diameters.
- Agricultural Irrigation Hub: Rapid maintenance connections between main pipelines and branch pipelines with stepped different diameters at pump stations.
- Energy Pipeline System Retrofit: 4-inch large-diameter pipeline extensions with different diameters without welding.
advantages
- Dual-diameter high-pressure sealing: 25 bar operating conditions with different diameter 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.
- Full range of diameter coverage: From 1/4“ to 4” diameter, suitable for applications ranging from miniature instruments to main pipeline renovations.
- Fluid Optimization Design: Conical flow channels ensure smooth medium transition in variable diameter sections with pressure loss ≤5%.
- Armor-Grade Corrosion Resistance: Hot-dip galvanized coating passes 3,000-hour industrial acid/alkali and salt spray tests.
- Vibration-resistant structure reinforcement: Thickened variable diameter wall design enhances impact resistance by 50% compared to standard components.
- Installation efficiency revolution: Single-piece replacement of flange assemblies + variable diameter pipes saves 85% installation time.
- Heavy-duty diameter assurance: 4-inch variable diameter pipe clamps maintain a 25 bar pressure-bearing structure with zero deformation.
packing
- Stepped port protection: dual-specification injection-molded caps nested with different diameter threads + silicone sealing rings.
- Conical cushioning system: EPE pearl cotton molded variable-diameter curved surface adaptive wrapping.
- Anti-corrosion armor layer: vapor-phase anti-corrosion film + honeycomb aluminum plate composite vacuum sealing.
- Precision anti-error structure: laser-cut pine wood irregular slots fitted and locked according to dimensions.
- Heavy-duty load-bearing solution: I-beam steel frame fumigated wooden box (compatible with DN100 load-bearing capacity).
- Anti-rolling design: inner box V-shaped steel rails locking tube clamps for zero displacement during transportation.
