With advanced CNC equipment and experienced engineers, the company supplies products for architectural decoration, medical equipment, fire-fighting systems, and industrial facilities, exporting globally to Japan, Europe, America, Southeast Asia, and beyond.

1. Common Problems

a. Leakage

Leakage often occurs due to improper installation, excessive bending, or worn-out sealing elements.

b. Corrosion

Exposure to corrosive chemicals or saline environments can degrade the joint material if the wrong grade is selected.

c. Fatigue and Cracking

Repeated vibration, pressure surges, or thermal cycling can lead to metal fatigue and cracks in the flexible joint.

d. Blockage or Flow Restriction

Debris, scaling, or sediment buildup inside the joint can reduce flow efficiency and affect system performance.

e. Connection Failures

Improperly tightened or incompatible connections may cause detachment or leakage.

2. Prevention Measures

• Material Selection: Use 304 SS for general applications and 316 SS for corrosive or saline environments.
• Proper Installation: Avoid over-bending, ensure correct alignment, and follow manufacturer guidelines.
• Regular Inspection: Monitor for signs of corrosion, leaks, or fatigue and replace components as needed.
• System Pressure Control: Use dampers or expansion loops to reduce pressure surges and vibration.
• Clean Fluid Systems: Filter fluids and prevent debris accumulation to avoid blockages.
• Sealing Maintenance: Periodically check gaskets, O-rings, and sealing elements for wear.

4. Installation Guidelines

• Alignment: Ensure the joint is correctly aligned with connected pipes to avoid stress.
• Support: Use proper pipe supports to prevent sagging or undue strain.
• Bending Radius: Do not exceed the recommended bending radius to maintain flexibility and avoid fatigue.
• Tightening: Secure connections to manufacturer torque specifications to prevent leakage or damage.

5. Recommended Usage Scenarios

• Industrial piping systems with vibration or thermal expansion.
• Fire-fighting water distribution systems requiring flexibility and durability.
• HVAC systems where vibration damping is necessary.
• Medical equipment and chemical process lines with corrosive or high-purity fluids.
