application
- Equipment corner connections: For wall-mounted equipment such as boilers and heat exchangers, external threads connect directly to the equipment ports, while internal threads connect to the piping. A 45° bend perfectly avoids wall obstacles.
- Precision piping layout for instrument panels: On the back of control cabinets and electrical panels, small-sized elbows (e.g., 1/2″) achieve smooth bends in a 3cm limited space, eliminating pipe twisting.
- High-pressure energy-saving system: Class 300-grade piping for air compressors (rated for 2000 psi pressure), with a 45° design reducing pressure loss by 40% and minimizing energy waste.
- Compact connections for corrosive environments: Hot-dip galvanized plates are used in ship engine rooms and chemical plant reagent pipelines to replace flange connections and prevent rusting.
- Emergency repair and renovation: Local adjustments to the pipeline system can be quickly completed in 20 minutes using threaded connections, without the need for production shutdowns or welding.
advantages
- Dual Thread Space Magician:
- External Thread (Male) End: Directly connects to equipment interfaces;
- Internal Thread (Female) End: Connects to pipeline systems, eliminating the need for one adapter and reducing leakage risk by 60%.
- Dual Pressure Rating Precision Coverage:
- Class 150: General-purpose, 300 psi pressure rating, suitable for a wide temperature range of -29°C to 66°C;
- Class 300: High-pressure specialized (e.g., 1-1/2″ with 1500 psi pressure rating), 80% increase in safety redundancy.
- Earthquake-resistant long-life design:
- Forged cast iron (ASTM A197) resists mechanical impact, with a 50% longer lifespan than ordinary cast iron;
- NPT tapered thread self-sealing, UL/FM certified leak-proof.
- All-environment defense shield:
- Hot-dip galvanized coating with salt spray resistance >900 hours, suitable for coastal/industrial corrosive environments;
- Black iron version with phosphating treatment, suitable for dry environments.
- 70-second rapid installation: Manual tightening completes the process, saving 5 hours per node compared to welding.
packing
- Threaded Armor-Grade Protection:
- External threaded sleeves with silicone anti-collision caps, internal threads coated with food-grade anti-rust oil + heat-shrinkable film sealing;
- Main body wrapped in pearl cotton, embedded in high-pressure-resistant EPS molds to prevent transportation breakage.
- Pressure-Sensitive Smart Packaging:
- Class 150: Blue-labeled boxes, 35 pieces per box (≤1″), honeycomb paper trays with dividers + humidity indicator cards;
- Class 300: Red-labeled box, 10 pieces per box (high-pressure components individually sealed), box marked with “high-pressure lightning” symbol.
- Large-item special solution:
- ≥2″ elbows use reusable steel frame boxes with casters on the bottom for direct on-site towing;
- Boxes embedded with NFC chips for mobile phone access to installation videos.
- Dual safety measures:
- Products are cast with “CL150/300” pressure rating markings;
- Outer boxes are labeled with a 45° turning diagram, with arrows indicating “external thread → equipment, internal thread → pipeline.”
