application
- Smooth Turning System: Water pump outlet, compressor piping, 45° turn reduces water hammer impact by 60%, protecting valves and instruments.
- Long-distance Inclined Piping: Mine conveying pipes, slope fire protection piping, replacing multiple 90° elbows to achieve smooth turns.
- Precision spatial adjustment: Behind control cabinets/instrument panels, small-sized elbows (e.g., 1/4″) enable precise adjustment of pipeline angles in extremely narrow spaces.
- Energy-efficient fluid systems: HVAC chilled water pipes reduce turbulence pressure loss, lowering system energy consumption by 15%.
- High-pressure safety upgrades: Class 300-rated for hydraulic stations and air compressor piping, withstanding 2000 psi impact pressure.
advantages
- Golden Angle Design:
- 45° bend optimizes space and flow efficiency, with pressure loss only 40% of a 90° elbow;
- Extremely short center distance (e.g., 1/2″ Class 150 is only 22.4mm), saving installation space.
- Dual pressure ratings cover all requirements:
- Class 150: General-purpose, temperature range -29°C to 66°C, pressure rating 300 psi;
- Class 300: High-pressure specialized, 2000 psi safety margin increased by 80%.
- Seismic-resistant long-life structure:
- Ductile iron (ASTM A197) resists mechanical impact, with a lifespan 50% longer than ordinary cast iron;
- NPT threaded double seals, UL/FM certified for leak prevention.
- Full environmental protection:
- Hot-dip galvanized coating with salt spray resistance >900 hours, suitable for coastal/chemical plant environments;
- Black iron version with phosphating treatment, suitable for rust prevention in dry environments.
- 1-minute quick installation: Manual tightening completes the process, 20 times faster than welding.
packing
- Threaded Armor Protection:
- Threaded ends are coated with long-lasting anti-rust grease, covered with silicone caps and double-layered heat-shrinkable film for protection.
- Elbow bodies are wrapped in pearl cotton and embedded in pressure-resistant EPS molds to prevent breakage.
- Pressure-graded intelligent packaging:
- Class 150: Blue-labeled boxes, 40 pieces per box (≤1″), paper dividers + humidity indicator cards;
- Class 300: Red-labeled box, 15 pieces per box, with a “high-pressure lightning” warning label printed on the box.
- Revolutionary solution for large items:
- ≥3″ elbows use recyclable steel frame boxes with swivel casters on the bottom;
- Built-in NFC chip, scan to obtain installation torque parameters.
- Error-proofing traceability system:
- Product casting with “CL150/300” pressure rating;
- Outer box labeled with a 45° angle to avoid confusion with 90° elbows.
