Increased Pressure Fluid Carrying Pipeline System And Method Therefor
US Patent:
5938246, Aug 17, 1999
Filed:
Feb 10, 1997
Appl. No.:
8/798362
Inventors:
Thomas C. Wallace - Denver CO
David W. Wallace - Denver CO
David W. Wallace - Denver CO
International Classification:
A16L 1706
US Classification:
285351
Abstract:
A method of maximizing system operating pressure capability of a selected flange joint in a fluid carrying pipeline system comprises minimizing bold load operating conditions and bolt load pre-load conditions at the selected flange joint by interposing a self-energizing seal assembly having negligible "m" and "y" values in surrounding relation to the joint's axial bore. The load producing moment resulting from connection of the flanges with the bolts is minimized by interposing a gasket element having a gasket thickness less than the seal thickness of the self-energizing seal assembly. The gasket element is interposed in a surrounding relation to the seal assembly at an outer radial location proximate to the outer flange surface margin. The flanges are connected with the bolts to form the flange joint while supporting the self-energizing seal assembly and the gasket element at the inner and outer radial locations, respectively, thereby to compress the self-energizing seal from the seal thickness to the gasket thickness. A method is also provided for forming a high pressure fluid carrying pipeline system adapted to convey a fluid at a system pressure of at least 1000 PSI.
Tandem Seal Device For Flow Line Applications
US Patent:
5564715, Oct 15, 1996
Filed:
Oct 15, 1993
Appl. No.:
8/138129
Inventors:
Thomas C. Wallace - Denver CO
Assignee:
Corrosion Control Corp. - Lakewood CO
International Classification:
F16J 1512, F16L 5800
US Classification:
277 58
Abstract:
A tandem seal device is provided for interposing and compressing between joined pieces of pipe in a flow line to prevent fluid leakage therebetween. The tandem seal device comprising a retainer body having an inner pair and an outer pair of continuous grooves. A first pair of seal elements, fabricated from a first material, being disposed in the inner pair of grooves. A second pair of seal elements, fabricated from a second material, being disposed in the outer pair of grooves.
