W-ring seal

spring-energizedmetalpiston

• Gas & steam turbines • V-Band Coupling • Very low load flanges or joints with considerable movements Sonkit Metal W-rings (E-Seals) are designed to have low load, high spring back performance for high pressure/temperature applications. In service, Metal W-rings are pressure energized by the system which increases the contact stress and further minimizes leakage. The geometry of the Metal W-ring can be designed to meet the requirements for each unique application and can be manufactured in a wide range of sizes. Specifications: 01 High springback/low load 02 Seal profile and wall thickness designed to control loading and springback 03 Available for internal and external pressure 04 Large and segmented diameters available (>2000 mm) 05 Functional Pressure: 100+ bar 06 Functional Temperature from -273°C to 730°C 07 Range of materials (Alloy X750, 718L, etc) 08 Tribological wear resistant coatings available 09 Custom profiles and sizes available Application Characteristics 1.Low Seating load can make the metal seal fully contact and ensure the sealing effect . 2. Good sealing performance with : • High temperature resistance • High pressure resistance • Wear resistance • Corrosion resistance
