Each portion subtends an angle measured about the point. Each portion is characterized by the distance from the point to the centroids of the cross sections within the portion. Centroids of the cross sections in a first portion are positioned at the same distance from the point. Centroids of the cross sections in another portion are positioned at respective points different from the distance associated with the first portion. By offsetting the centroids leak paths are intentionally created before the joint is crimped to prevent false indications of a crimped joint. | 11-24-2011 |

Gasket corrugation is shape-memorized to operating “swelling” at temperature of direct martensitic phase transformation from austenite to martensite of the SMA being compressed to obtain some quantity of residual contraction corresponding to stress-induced martensite formation. A free “swelling” of deformed gasket corrugation at operating temperature defines the “negative creep” effect of the gasket, and it is blocked by rigid flanges with appearance of reactive shape-recovering stresses between the gasket corrugation and flange surfaces. The reactive shape-recovering stresses have direction inverse to the direction of operating creep of the gasket providing leak-tight, multiple, automatic and continuous seal between the flanges of the BFC. Methods of manufacturing of “negative creep” corrugated gasket are disclosed. | 11-15-2012 |
