Conventional threaded closures, operating under high pressure, experience great stress concentration. The Gasche Resilient Thread Closure redistributes this stress by utilizing a flexible spring, which actually forms the thread. This design increases cycle life and cost effectiveness, because the thread is replaceable. Many different seal configurations can be used with this closure method, and it is offered with a straight or a tapered thread (quick opening).
Vessels designed for high temperature/high pressure, batch type chemical reactions.
Gasche Resilient Thread Closure Pressure Vessels : Pressure Vessels
Improved thread design provides superior safety and service
FEATURES
Pressure ranges:
2,000 to 48,000 psi (138 to 3,309 bar)
ID range - 8 to
48" (203 to 1,219mm), IL's are based on application
Designed for high pressure and or temperature conditions where cycling is involved
A wound spring w/inner rod forms the thread, this is housed in the cover groove, which then engages the vessel body
Redistributes thread stress from the first thread to subsequent threads further up the closure, thus increasing cycle life
Supplied with a variety of seals such as O-ring, flat gasket, or modified Bridgman
Repeated cycling will not cause closure deformation
Thread spring is replaceable when worn out
Even large covers can be turned easily because of the rounded surface design of the resilient thread
Custom designed to meet specific application goals
BENEFITS
The Gasche Resilient Thread Closure ensures greater reliability of large pressure vessels subjected to many different operating environments. The flexible thread, which is replaceable when worn, redistributes the stress across the length of the entire thread, thus reducing the concentration on the bottom one or two threads. The reduced stress concentration increases cycle life and improves overall performance.
