application
- Equipment integration renovation: Specifically designed for systems that require simultaneous pipe diameter changes and equipment connection, internal threaded branch pipes are directly connected to instruments such as pressure gauges and relief valves, suitable for critical nodes such as pump rooms and energy stations.
- Compact space optimization: The concentric diameter change structure saves installation space, suitable for narrow areas such as pipe wells and equipment layers, avoiding leakage risks caused by multiple adapters.
- Precision Fluid Control: Designed for small-flow branches in HVAC and water treatment systems that require real-time monitoring, this solution integrates pipe diameter reduction with instrumentation integration
advantages
1. Three integrative design:Concentric Reducer: Coaxial alignment, smooth fluid flow during transition, and 30% lower pressure loss;Groove Connection: GROOVE system with quick-fit fittings on main lines at both ends, high seismic resistance and 300-500 psi rated pressure class; Internal Threaded Branch Pipes (NPT/BSPT): All calibration equipment by tightening the internal thread to eliminate sealing point.
2. Installation Along Minute: Energy Groove Connection, Save Welding or Flange Alignment;Thread Branch pipeline Direct Screw to the equipment(e.g. fuel tank);Triple Speed for Installation of Thread branch pipelines
3. Extraordinary environmental resistance: Ductile iron body(ASTM A536) with red paint/hot-dip galvanized, liquid epoxy coated which is anti-resistant to chemical corrosion and provide excellent mechanical stabilities in the temperature range of -30°C to 150°
4. All-scenario compatibility: Compatible with pipe sizes ranging from 1-1¼”×1” to 8”×4” (DN40-DN200), so able to meet wide range of needs from residential to industrial applications
packing
- Triple Interface Special Protection:
