application
- Fine-tuning pipe routing: Suitable for scenarios requiring precise turning at small angles (e.g., densely packed chemical plants, precision instrumentation piping systems).
- Long-distance gentle curve system: Mining conveying pipelines, municipal water supply main pipelines, achieved through the combination of multiple 22.5° elbows to create smooth curved piping layouts.
- Vibration reduction and noise reduction design: Suitable for pump inlets/outlets and air compressor pipelines, where small-angle turns minimize fluid impact vibrations and noise.
- Space-constrained areas: Ideal for building interlayers and ship engine rooms, where the design minimizes space requirements for turns.
- Fire protection system upgrades: Replaces 90° elbows to retrofit aging pipelines, improving water flow efficiency without requiring significant adjustments to supports.
advantages
1. Ultra-low resistance: The 22.5° design reduces pressure loss by 40% compared to 45° elbows, significantly reducing energy consumption.
2. Precision fit: The standard bending radius ensures consistent turning and prevents stress concentration in the pipeline.
3. Superior pressure resistance: The ductile iron (ASTM A536) structure enhances deformation resistance by 25% under 500 psi high pressure.
4. Maintenance-free design:Hot-dip galvanized coating with weather resistance ≥20 years (red paint version suitable for indoor dry environments);Grooved joints self-seal, eliminating the need for regular tightening.
5. Plug-and-play: Compatible with any brand of grooved fittings, installation time is only 1/10 of that required for welded elbows
packing
- Differentiated Protection:
- ≤4 inches: 20 pieces per box, sealed with PE bags + corrugated cardboard partitions, moisture-proof and rust-proof;
- >4 inches: individual wooden boxes with top and bottom lids, embedded with EPE foam molds, and suspended bends for shock absorption.
- Key Component Protection:
- Silicone rings are fitted around groove areas to prevent impact and deformation;
- Wear-resistant PET protective film is applied to the outer sides of bends.
- Smart Traceability Packaging:
- Outer box printed with installation angle diagram (22.5° mark);
- QR code linked to pressure test report, scan to verify authenticity.
- Large Item Dedicated Solution:
- 10“-12” elbows use steel frame wooden pallets with anti-slip rubber nails on the bottom;
- Single pallet load limit of 1 piece, with “center of gravity offset” warning label.
