application
- High-pressure equipment interfaces: air compressors, hydraulic system inlets and outlets, right-angle bends capable of withstanding high pressures of 1000-2000 psi (Class 300).
- Precision instrumentation piping: pressure gauges, flow meters, and connecting branches, with NPT threads ensuring leak-free sealing.
- Industrial steam piping: Temperature range from -29°C to 66°C, suitable for low-pressure steam pipes in boiler rooms (Class 150).
- Mobile equipment piping: Generator sets, construction machinery, threaded connections for quick assembly and disassembly, resistant to vibration deformation.
- Corrosive environment retrofitting: Hot-dip galvanized plates for coastal factories and chemical plants with saltwater piping, black iron plates suitable for dry indoor environments.
advantages
- Overpressure Dual Safety:
- Class 150: Economical, meets standard 300 psi system requirements;
- Class 300: High-pressure version, withstands 2000 psi burst pressure without failure, increasing safety redundancy by 50%.
- Earthquake-resistant and crack-resistant design: Malleable cast iron (ASTM A197) has better ductility than ordinary cast iron, increasing impact resistance by 30%.
- Zero-Leakage Threads: NPT tapered threads with self-sealing design, no additional packing tape required (UL/FM certified).
- Full-scenario compatibility:
- Covers all sizes from 1/4“ to 6”, from small instrumentation tubing (1/4“) to industrial mainlines (6”);
- Hot-dip galvanized coating >85μm, salt spray test >720 hours without rusting.
- 30-second quick installation: Threaded connections can be directly tightened, saving 95% of welding time.
packing
- Thread Ultimate Protection:
- Each threaded end is coated with food-grade anti-rust oil and fitted with a double-layer PE + silicone cap;
- The elbow body is wrapped in pearl cotton to prevent brittle fractures caused by transportation impacts.
- Smart Packaging System:
- ≤2 inches: 50 pieces per box, with internal compartment paper trays + desiccants, and external boxes marked with pressure rating labels (150/300);
- >2 inches: Single-piece wooden box with lid, featuring an embedded high-density EVA mold for suspended shock absorption.
- Anti-counterfeiting and Traceability Solution:
- Product body laser-engraved with pressure rating (e.g., “CLASS 300”);
- NFC chip inside the box, allowing mobile phone scanning to view UL/FM certification certificates.
- Large Special Packaging:
- 6-inch bends use removable steel frame boxes with rubber anti-slip nails on the bottom;
- Wooden boxes with built-in temperature and humidity recorders, with transport data accessible via the cloud.
