description
Heavy-duty flexible grooved couplings are high-strength flexible raccords de tuyauterie, used in pipeline systems with high load-bearing requirements. They allow for a certain relative displacement between pipes to compensate for deformation or absorb vibration

application
- Heavy-load Pipeline Vibration Damping: Suitable for the fields of large-scale pumps/compressors/vessels inlets and outlets, power & industrial pipelines, fire protection project main lines with high pressure and vibration damping needs;
- Dynamic displacement compensation : Applicable for pipelines in areas with larger thermal expansion and contraction movement or foundation settlement; achieving the bypass of displacement while keeping connecting safe.
- High Safety Standard Facility, Ultra-critical applications: Certified by UL/FM for fire safety and used in hospitals or airports where any leaks are not allowed.
- Supports pipe diameters from 2 inches to 12 inches (DN50-DN300): Compatible with steel and ductile iron pipes.
avantages
1. High Strength & Flexibility: Rough design offers high loading capacity, flexible structure absorbs impact under load, and helps protect the pipeline from vibration damage.
2. Smart displacement adjustment: Automatically compensates thermal CNC machining and contraction or slight displacement of pipes to avoid excessive stress at connections which may cause cracking.
3. Sealing design: Top plateau sealing can maintain zero leakage of water, oil and gas media under high pressure (500 psi).
4. Fast to Install: Grove connections do not require welding nor perfect alignment — just fit and tighten the bolts, which saves more than 50% in labor hours.
5. Long life: The body of ductile iron, inner and exteneral corrosion resistant coating (red paint/galvanized), anti-corrosion and wear-resistant, will not can be used in underground or humid environments.
6. Quick maintenance: the dismountable design makes it easy to replace gasket or bolts, without cutting from pipeline, save much maintain cost.
emballage
- Industrial-grade protection:
- Each item is individually packaged in a hard cardboard box, with a moisture-proof bag and installation guide included inside.
- The outer box is clearly labeled: Heavy-duty flexible joint, 8 inches, high pressure.
- Large-Size Reinforcement:
- 6 inches and above use custom wooden boxes + anti-vibration foam, with special protection for flanges and moving parts.
- Bulk Transportation:
- Metal pallets for support, wrapped with stretch film + steel straps for fixation, suitable for long-distance sea/land transport, ensuring safe delivery
