Composition
| Type of Spiralwound | |
|---|---|
| SW | without rings |
| SWI | with inner ring |
| SWC | with outer ring |
| SWCI | with outer and inner rings |
Characteristics
The spiral wound gasket must meet compressibility and elasticity requirements to ensure sealing. For this reason, Carrara manufactures spiral wound gaskets using modern machines with controlled winding tension, always providing a product that meets the technical specifications of industry standards.
The temperature range of the spiral depends on the thermal resistance of the metals and fillers. Graphite cannot be used with oxidizing fluids.
| Temperature Range of the Filler °C | |
|---|---|
| PTFE | 260 |
| GRAPHITE | 550 |
| MICA | 900 |
| CERAMIC | 1000 |
Applications
Semi-metallic gaskets for pipeline flanges, valve flanges, and equipment.
