SCALING WARE - EXPANSION JOINT
Product Model: VSSJA
Product Overview
The VSSJA Expansion Joint is designed to absorb thermal expansion, vibration, and misalignment in piping systems. Widely used in water supply, drainage, HVAC, and industrial applications, this joint ensures reliable operation by compensating for dimensional changes caused by temperature fluctuations or mechanical stress.
Key Features
- High Flexibility
- Absorbs axial, lateral, and angular movements in pipelines.
- Reduces stress on connected equipment (pumps, valves) and prevents pipe damage.
- Durable Construction
- Materials: Stainless steel or alloy steel bellows with corrosion-resistant coatings.
- Design: Engineered to withstand high pressure (0.6-1.6 MPa) and temperatures up to 80°C.
- Easy Installation
- Available in flanged or welded configurations for seamless integration into existing systems.
- Compact design minimizes space requirements.
- Versatile Applications
- Suitable for water, steam, oil, and other non-aggressive fluids.
- Commonly used in power plants, chemical processing, and building services.
