Technical Features of Inflatable Seals
Inflatable seals offer a range of advantages due to their unique design and functionality. Their primary function is to create a tight seal by inflating a flexible membrane against a mating surface. This adaptability makes them suitable for various applications where a consistent, reliable seal is crucial. The material selection is critical and greatly influences the seal’s performance and lifespan.
| Feature | Description |
|---|---|
| Material | Common materials include rubber (EPDM, NBR, Silicone), polyurethane, and PTFE. The choice depends on the application’s specific requirements, such as temperature resistance and chemical compatibility. |
| Inflation Method | Typically pneumatic, using compressed air or other gases. Some seals might incorporate hydraulic systems for higher pressure applications. |
| Shape & Size | Available in various shapes and sizes, including circular, rectangular, U-shaped, and custom designs, to suit different applications. |
| Pressure Range | Inflatable seals can operate across a wide range of pressures, from vacuum to high pressure, depending on the design and material used. |
| Durability | Fabric reinforcement significantly enhances the durability and lifespan of the seal, especially in demanding applications. |
| Temperature Range | Operable across a wide range of temperatures, depending on the chosen material. High-temperature applications often require specialized materials like silicone or PTFE. |
Types of Inflatable Seals
Different types of inflatable seals cater to specific applications. The choice depends on factors such as the shape of the opening to be sealed, the required pressure range, and the operating environment. Companies like IKSonic (www.iksonic.com) and Pawling (www.pawlingep.com) offer extensive customization options.
| Type | Description | Advantages | Limitations |
|---|---|---|---|
| Circular | Seals circular openings, often used in tanks, pressure vessels, and hatches. | Simple design, easy installation, effective sealing. | Limited to circular applications. |
| Rectangular | Seals rectangular openings, common in doors, gates, and process equipment. | Adaptable to various sizes, effective sealing. | May require custom design for complex shapes. |
| U-Shaped | Seals U-shaped openings, often found in gates and other specialized equipment. | Effective sealing, adaptable to various sizes. | More complex design, potentially more difficult installation than circular or rectangular. |
| Custom Designed | Designed and manufactured to meet specific application requirements. | Precise fit, optimal performance for specific applications. | Higher cost, longer lead times. |
