Description
The Walraven 2S Rubber Lined Clamps offer a secure, vibration-resistant solution for pipe installations across multiple materials, including steel, copper, cast iron, and multilayer plastics. Constructed from durable zinc-plated steel, it ensures long-lasting corrosion resistance and mechanical strength, making it suitable for both commercial and industrial applications.
The integrated rubber lining provides excellent sound insulation and a strong grip, preventing slippage between the pipe and clamp while significantly reducing structure-borne noise. Engineered for performance, this design supports installations exposed to temperature variations from -30 °C to +120 °C without compromising stability or noise reduction.
What does "Gapless" mean?
Gapless clamps are designed to close completely around the pipe, leaving no gap between the clamp ends once tightened. This ensures an even distribution of pressure and eliminates movement that can lead to noise or vibration. The continuous grip enhances pipe stability, especially in high-vibration environments, providing both acoustic and mechanical benefits.
What are "Anti-Loss Washers"?
Anti-loss washers are integrated components that prevent the clamp’s screws from detaching during installation. They secure the screw in place even when loosened, allowing the installer to position and adjust the clamp with one hand. This feature saves time, reduces the risk of dropped parts on site, and contributes to a safer and more efficient installation process.
Key Features & Benefits
Gapless Design: Provides full circumferential contact for stable and even clamping pressure.
Rubber Lining: Prevents pipe movement and reduces vibration and noise transmission.
Anti-Loss Washers: Simplify installation and prevent component loss on site.
Corrosion Resistance: Zinc plating ensures long-term protection in humid or corrosive environments.
Wide Temperature Range: Suitable for a variety of heating, cooling, and water supply systems.
Noise Control: Tested to ISO 3822-1 for up to 22 dB(A) noise reduction.
Versatile Compatibility: Fits steel, copper, cast iron, and plastic pipes.
