application
- Fire sprinkler branch pipe turning connection external thread valve/nozzle;
- HVAC pipe corner connection thermometer/pressure gauge;
- Industrial equipment (pump body/storage tank) limited space turning connection external thread interface;
- Ship piping compact layout connection instrument sensor.
advantages
1. 90°bend dual interface: Groove end clamp to fix the pipeline for the main pipe + internal thread end (NPT/BSPT) directly connected with an external threaded device, satisfy bending and connecting requirements in one step.
2. Narrow space adaptation: L1/L2 short arm design (see document parameters) minimizes installation space, resolving equipment corner challenges in confined areas.
3. Twice as strong: There is no welding to weaken the connection, and the 3.3-minute installation is approximately three times faster than using a traditional flanged elbow.
4. Leak-proof under high pressure : Ductile iron one piece casting. zero leakage testing certified by UL/FM over 300-500 psi working pressure.
5. Universal standard threads: NPT/BSPT standards, can be matched with American, European and Asian equipment
packing
- Individual protection: Threaded hole wax injection for damage prevention + anti-rust oil coating on inner walls, fully wrapped in bubble wrap, reinforced cushioning layer at elbow joints
- Unified packaging solution: High-strength corrugated cardboard box (25×15×10cm) + EPE foam compartments, each box contains 6 pieces (small size) or 3 pieces (large size), with threaded dust caps
- Outer box labeling: Elbow directional diagram + “Internal threaded end ↑” orientation mark, specification labeling (e.g., “1-1/2” × 1“ NPT L1=49mm”), UL/FM certification mark + quantity/gross weight
- Export compliance: Complies with ISTA 1A standard, stacking height limit of 5 layers.
