Ring Fixed Clamp

What is a Ring Fixed Clamp?

A Ring Fixed Clamp is a mechanical fastening device that applies 360° circumferential pressure around a groove/ring seat on a nozzle or fitting, ensuring a rigid and stable connection. This type of clamp prevents slippage, rotation, and leakage even under vibration and medium-to-high pressure conditions.

Key Advantages:

• Full 360° contact → even load distribution

• Fixed type → stable angle/position

• Compact design → suitable for tight spaces

Applications

• Spray Systems: Mounting flat fan, hollow cone, or full cone nozzles on spray bars

• Washing & Rinsing Lines: Conveyor washing, CIP distribution

• Chemical & Coating: Surface wetting, pre-treatment spraying

• Steel & Mining: Dust suppression, cooling, descaling

• Water & Wastewater: Scrubbers, tank washing supply lines

• Agriculture: Boom-mounted nozzles with fixed angle spraying

Design Principles & Technical Notes

• Ring Fit: The clamp’s inner profile matches the ring shoulder on the nozzle body.

• Tightening Mechanism: Usually dual-bolt or circumferential bolts; torque applied in cross pattern.

• Sealing: Provided by O-rings/gaskets; clamp ensures mechanical lock & rigidity.

• Vibration Resistance: 360° grip minimizes rotation or micro-slippage, keeping spray angle consistent.

Technical Specifications (Guide Values)

Installation Guide

1. Surface Prep: Clean bar/pipe and nozzle seat from dirt/oil.

2. Seal Selection: Use EPDM/FKM/PTFE O-rings depending on chemistry/temp.

3. Pre-Positioning: Place nozzle body into the ring seat.

4. Clamp Mounting: Fit ring fixed clamp, close the cover.

5. Cross Tightening: Apply torque in cross pattern (M6: 6–8 Nm, M8: 12–18 Nm).

6. Angle & Alignment: Check fan direction; align all nozzles consistently.

7. Pressure Test: Gradually pressurize; inspect for leaks or vibration issues.

Design & Selection Tips

• Spray Coverage: For flat fans, consider angle (60–110°) + distance + pitch for overlap.

• Line Velocity: Keep manifold velocity ≤ 2–3 m/s to avoid noise/pressure loss.

• Filtration: Use mesh filters with small-orifice nozzles.

• Vibration Management: Long spray bars need supports/dampers.

• Material Match: Acid/solvent → SS316/PVDF; water/alkaline → SS304/PP.

Maintenance & Checklist

• Weekly: Check clamp tightness and spray angle stability

• Monthly: Inspect O-ring wear and ring seat for corrosion/scratches

• Every 3–6 Months: Chemical/ultrasonic cleaning (verify material compatibility)

• Spare Parts: Keep clamps, bolts, and seals in stock for critical lines

• Safety: Never disassemble under pressure; apply LO/TO

FAQs

How do I match clamp to ring seat? Clamp profile must match nozzle groove dimensions.
What torque should I use? Always follow datasheet; general guide: M6: 6–8 Nm, M8: 12–18 Nm.
How to select material? Match with process fluid MSDS: acids/solvents → SS316/PVDF, water → SS304/PP.
Why does spray angle shift? Causes: insufficient torque, wrong seal, excessive vibration.

Conclusion

The Ring Fixed Clamp is a robust solution for secure nozzle fastening in industrial spray applications. Its rigid 360° grip, stable angle, and high-pressure resistance make it ideal for long-term, low-maintenance performance. With proper material selection, torque application, and filtration, you can achieve leak-free, stable spraying in demanding environments.
