Abstract
A wire-mesh gasket fashioned from heat-treatable materials such as beryllium copper alloy wire is knitted or braided into a tubular structure. Plural wires may be used. Various cross-sectional configurations such as circular, teardrop, double lobed, and finned with and without cores are available. Cores may be air, elastomeric, or wire mesh. The formed tubular structure is heat-treated after forming using appropriate time-temperature cycles to strengthen and/or stress relieve the material.
Claims17
A method of making a wire-mesh gasket structure comprising the steps of:
- selecting a heat-treatable wire in a soft temper condition;
- forming the heat-treatable wire into a tubular wire-mesh structure having a nominal dimension;
- and
- heat treating the tubular structure to a high temper condition whereby hardening occurs and forming stresses are relieved.
A method of making a wire-mesh gasket comprising the steps of
- selecting a wire in a pre-hardened condition;
- forming the pre-hardened wire into a tubular structure having a nominal dimension;
- heat treating the pre-hardened wire to a higher strength condition whereby forming stresses are relieved.
