Xlong seal spring energized seal is a U-shape spring energized seal function with single acting sealing element. The spring which energized the PTFE jacket actuates the sealing legs(lips) of the seal. The system pressure assists the spring in creating a leak tight seal between the sealing lips and the mating metal parts. The springs assist in slight misalignment, jacket wear, and maintaining a consistent sealing pressure against the desired target.
Spring energized seal has been designed specially to overcome the problems associated with PTFE composite or other high performance plastics like UHMW-PE and elastomer. They are suitable for static, rotary, and reciprocating application in temperatures from -200 º C to 300 º C, pressure from vacuum to 700kg/cm and speed up to 20m/s, to survive the most corrosive enviroment. Three different types of spring energizer are made from corrosion resistant metal alloys such as stainless steel, Elgiloy and Hastelloy to meet most serious corrosive and high temperature application.
Standard spring energized seal are precisely machined to fit AS 568A glands in radial rod, piston and axial face-seal configurations. Spring energized seal can replace most of o ring used in mechanical seal and extend total sealing performance and service life in very aggressive chemical, petrochemical process.
Spring engerized seal are used in dynamic and static applications where elastomer seals cannot meet the extreme operating conditions of harsh environment. Furthermore, spring enegized in hydraulic components where low friction, high lateral load, corrosive of steam environment are required.
Xlong seal always does his best to introduce the most innovative and cost-effective sealing solutions to local customers to help them conquer every difficult sealing problems. Thanks to latest seal-making CNC machine and well-proved worldwide material resource, Xlong seal can produce a spring energized seal specifically meeting your requirements very quickly, This would be the best way for our commitment " To provide excellent sealing performance with extended service life by our sincere effort" to all our customers.
| Main Applications: |
| Spring energized seal is designed for thermal and/or corrosive extremes that make the requirement for a stable seal leg unobtainable using other designs or material.It demonstrates excellent capability to the control of friction loads and compensation of manufacturing tolerances or higher side load effects. |
| Some typical applications that are idea for spring energized seal are described as followings: |
| 1 | As face seals for swivel joints in loading or unloading arm equipment |
| 2 | As needle seals for the paint valves in painting equipment |
| 3 | As shaft and static seals in vacuum pumps |
| 4 | As seals for the filling valves of beverage or beer bottling plants and other foodstuffs industry |
| 5 | As better alternatives in hydraulic compoents,e.g.high pressure cylinders,low friction cylinders |
| steering units,and shock absorbers. |
| 6 | In chemical plant equipment and construction |
| 7 | In the automobile and aerospace industries |
| 8 | In metering units |
| 9 | High wear resulted from high lateral load or poor concentric running condition |
