| 20090134587 | High temperature negative creep gasket and manufacturing same - A negative creep gasket with corrugated core of high temperature Shape Memory Alloy (SMA) provides multiple leak-tight, automatic and continuous seal between the flanges of Bolted Flanged Connection (BFC) used in plant/piping systems that operate under critical conditions including a variety of high operating temperatures within the range of from 300° C. to 1120° C. The specific high operating temperature of the BFC is in the temperature interval of reverse martensitic phase transformation from martensite to austenite of the SMA from which gasket corrugated core is manufactured. The gasket corrugated core is shape-memorized to the “swelling” during gasket manufacturing and bolt preload force application, and a free gasket “swelling” due to shape recovery of initial configuration of the core is constrained by rigid flanges at high operating temperature of the BFC that leads to appearance of reactive shape-recovering stresses having direction inverse to the direction of operating creep of the gasket. The manufacturing of the high temperature negative creep gasket is disclosed. | 05-28-2009 |
