Abstract: A “negative creep” corrugated gasket of Shape Memory Alloy (SMA) for Bolted Flanged Connections (BFCs) operates under temperatures that are within the temperature interval of reverse martensitic phase transformation from martensite to austenite of the SMA. 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.
