Abstract

A corrugated metal gasket for use between two flanges wherein the corrugated metal gasket is produced by a method comprising the steps of providing an annular gasket substrate and machining into that substrate a plurality of substantially uniform and generally concentric corrugations.

Claims

exact text as granted — not AI-modified
1 . A corrugated metal gasket for use between two flanges, said corrugated metal gasket being produced by a method comprising the following steps:
 providing an annular gasket substrate; and   machining into said annular gasket substrate a plurality of substantially uniform and generally concentric corrugations.   
     
     
         2 . The corrugated metal gasket of  claim 1  which further includes an outer guide ring. 
     
     
         3 . The corrugated metal gasket of  claim 2  wherein said outer guide ring is integrated with said annular gasket substrate as a unitary corrugated metal gasket. 
     
     
         4 . The corrugated metal gasket of  claim 3  wherein the pitch of said corrugations is selected from the group consisting of approximately 0.125 inches and approximately 0.250 inches. 
     
     
         5 . The corrugated metal gasket of  claim 4  wherein an uncoated thickness of said corrugations is selected from the group consisting of approximately 0.093 inches, approximately 0.125 inches and approximately 0.250 inches. 
     
     
         6 . The corrugated metal gasket of  claim 5  wherein said corrugations are coated with graphite. 
     
     
         7 . The corrugated metal gasket of  claim 6  wherein an outside diameter of said corrugated metal gasket is approximately 6.88 inches. 
     
     
         8 . The corrugated metal gasket of  claim 6  wherein an outside diameter of said corrugated metal gasket is approximately 6.12 inches. 
     
     
         9 . The corrugated metal gasket of  claim 8  wherein an inside diameter of said corrugated metal gasket is approximately 4.87 inches. 
     
     
         10 . The corrugated metal gasket of  claim 1  wherein the pitch of said corrugations is selected from the group consisting of approximately 0.125 inches and approximately 0.250 inches. 
     
     
         11 . The corrugated metal gasket of  claim 1  wherein an uncoated thickness of said corrugations is selected from the group consisting of approximately 0.093 inches, approximately 0.125 inches and approximately 0.250 inches. 
     
     
         12 . The corrugated metal gasket of  claim 1  wherein said corrugations are coated with graphite. 
     
     
         13 . The corrugated metal gasket of  claim 1  wherein an outside diameter of said corrugated metal gasket is approximately 6.88 inches. 
     
     
         14 . The corrugated metal gasket of  claim 1  wherein an outside diameter of said corrugated metal gasket is approximately 6.12 inches. 
     
     
         15 . The corrugated metal gasket of  claim 1  wherein an inside diameter of said corrugated metal gasket is approximately 4.87 inches. 
     
     
         16 . The corrugated metal gasket of  claim 2  wherein said outer guide ring is a separate component which is assembled into said annular gasket substrate. 
     
     
         17 . The corrugated metal gasket of  claim 16  wherein said annular gasket substrate is constructed and arranged with an annular groove. 
     
     
         18 . The corrugated metal gasket of  claim 17  wherein said outer guide ring is assembled into said annular gasket substrate. 
     
     
         19 . A corrugated metal gasket for use between two members for sealing, said corrugated metal gasket comprising:
 an annular gasket substrate having a face surface and being constructed and arranged with machined corrugations in said face surface, said corrugations having a repeating sinusoidal shape.   
     
     
         20 . The corrugated metal gasket of  claim 19  which further includes an outer guide ring which surrounds said annular gasket substrate. 
     
     
         21 . A corrugated metal gasket for use between two members for sealing, said corrugated metal gasket comprising:
 an annular sealing core having a pair of opposing face surfaces and being constructed and arranged with machined corrugations in each face surface, said corrugations having a repeating sinusoidal shape.
