application
- HVAC System U-shaped Loop: Connect heating pipes to form a closed loop for balanced distribution of heat medium.
- Industrial Equipment Cooling Circulation: Establish a compact 180° return pipe between the cooling tower and equipment.
- Ship Engine Room Compact Piping: Achieve 180° pipe turns in confined spaces to save installation space.
- Chemical Reactor Bypass: Establish a short-distance return detection channel at the inlet and outlet of the reactor.
- Solar hot water system: Forms a closed-loop freeze-proof circulation loop between collector arrays.
- Laboratory equipment piping: Compact return connections for precision instrument cooling water systems.
- Fire pump room piping optimization: Short-distance 180° turn connections at the inlet and outlet of fire pumps.
- Agricultural irrigation return system: Forms a freeze-proof return loop at the end of greenhouse irrigation networks.
advantages
- Compact 180°Turn: Open design for easy pipeline turning in a minimal space.
- Dual Interface Precision Alignment: The optimized elbow design will ensure that pipes are straightly connected at both ends.
- High pressure fluid flow: smooth channel design is to reduce the loss of energy and turbulence so as to ensure continuity of delivery at low pressure difference.
- Chemical, or any Moisture Media: Thickened zinc coating is just resistant to all spread of corrosion from moisture and chemical media.
- Rapid Maintenance: The open design allows visual inspection and maintenance of exposed installations.
- Water Hammer Resistance: Full support through reinforced bend structure of system-pressure fluctuations
- Stability Over Extreme Temperatures: Material is stable at high temperatures and has no loss in structural integrity.
- Lifetime Maintenance-Free Guarantee: Lengthens lifespan with unique casting process.
packing
- Curved Surface Protective Pad: Custom PE foam is bonded to the 180° curved surface to prevent collisions.
- Threaded End Dual Protection: A combination of a screw cap and foam ring provides composite protection for the threaded ends.
- Single-Unit Shock-Absorbing Wrap: Bubble column bags completely cover the surface of the elbow.
- Open-Structure Filling: Internal filling with deformable foam prevents deformation during transportation.
- Smart size-specific positioning: Honeycomb cardboard compartments are categorized and secured by size.
- Visual flow direction markers: Outer boxes are printed with installation flow direction arrows and angle markers.
- Full-process traceability system: Laser engraving + smart QR codes for dual traceability.
- Anti-rolling packing design: Anti-rolling slots inside the box ensure transportation stability.
