application
- Wall-mounted equipment connections: Interfaces for wall-mounted equipment such as boilers and pumps, with external threads directly connected to equipment and internal threads connected to pipes, solving the problem of turning in narrow spaces.
- Dense wiring on instrument panels: Piping on the back of control cabinets and instrument panels, with small-sized elbows (e.g., 1/4″) enabling compact right-angle turns to avoid pipe crossings.
- High-pressure system safety upgrades: Air compressors and hydraulic stations with Class 300-grade piping, capable of withstanding 2000 psi high pressure, with threaded locking to prevent bursting.
- Corrosive environment direct connections: Hot-dip galvanized plates are used for seawater cooling pipes in coastal power plants and acid mist areas in chemical plants, replacing easily rusting flange connections.
- Emergency repair scenarios: Rapid repairs for pipe ruptures, with threaded connections eliminating the need for system shutdown and welding, enabling operation to resume within 30 minutes.
advantages
- Revolutionary dual-thread design:
- One head with straight thread (male): directly connected to the equipment at both ends;
- One end with internal thread (female) to connect to piping systems, which eliminates one joint and comes with leakage points reduced by 50%.
- Dual pressure rating coverage:
- _Class 150_ : General service, rating pressure 300 psi, temperature range -29°C to +66°C;
- Class 300 High-pressure specialized, with a 2000 psi burst pressure with a70% increase in safety margin.
- Seismic-resistant anti-loosening structure:
- Powder coated (black) to resist rust or corrosion. ▫Forged cast iron (ASTM A197) for high strength and mechanical impact resistance, 40% longer lifespan compared with regular nodular cast iron;
- Item Characteristics NPT tapered thread self-sealing design, which is resistant to vibration and has zero leakage.
- Full-scenario corrosion protection:
- hot-dip galvanized layer >80μm, salt spray test >1000 hours;
- e, Black iron using phosphating solution and can be used indoor dry environment.
- 90-second quick installation:
- No need for any specific tool, just manually tensioning, can save you 04hrs/node compared to welding.
packing
- Threaded Armor-Grade Protection:
- External threads fitted with silicone anti-collision caps, internal threads coated with food-grade anti-rust oil + heat-shrinkable film sealing;
- Elbow bodies wrapped in pearl cotton, embedded in high-density EPS molds to prevent transportation fractures.
- Pressure-Sensitive Smart Packaging:
- Class 150: Blue-labeled boxes, 30 pieces per box (≤1″), with internal compartment paper trays + humidity indicator cards;
- Class 300: Red-labeled box, 12 pieces per box, with a “high-pressure” lightning symbol printed on the box.
- Large-item special solution:
- ≥3″ elbows use a removable steel frame box with casters on the bottom for direct on-site transportation;
- NFC chips embedded inside the box for mobile phone sensing to obtain installation torque parameters.
- Error-proofing and traceability system:
- Product casting with “CL150/300” pressure rating markings;
- Outer box labeled with dual thread diagrams, arrows indicating “external thread → equipment, internal thread → pipeline.”
