Abstract
Official abstract text for this publication.
A magnetic flowmeter flowtube assembly includes a conduit having a first end with a first flange and a second end with a second flange. A fluoropolymer liner is disposed within and extending through the first flange, the conduit and the second flange. A first lining protector is mounted to the first flange and a second lining protector mounter to the second flange. A first spring-energized seal is disposed between the first lining protector and the fluoropolymer liner. A second spring-energized seal is disposed between the second lining protector and the fluoropolymer liner.
First claim
Opening claim text (preview).
What is claimed is: 1. A magnetic flowmeter flowtube assembly comprising: a conduit having a first end with a first flange and a second end with a second flange; a fluoropolymer liner disposed within and extending through the first flange, the conduit and the second flange; a first lining protector mounted to the first flange; a second lining protector mounter to the second flange; a first spring-energized seal disposed between the first lining protector and the fluoropolymer liner; a second spring-energized seal disposed between the second lining protector and the fluoropolymer liner; and wherein the fluoropolymer liner includes a first flared portion disposed between the first lining protector and the first flange. 2. The magnetic flowmeter flowtube assembly of claim 1 , wherein the first spring-energized seal is disposed in a groove of the first lining protector. 3. The magnetic flowmeter flowtube assembly of claim 2 , wherein the second spring-energized seal is disposed in a groove in the second lining protector. 4. The magnetic flowmeter flowtube assembly of claim 1 , wherein at least one of the first and second lining protectors includes an outer surface that is configured to couple to a pipe flange using a standard coupling. 5. The magnetic flowmeter flowtube assembly of claim 4 , wherein the standard coupling is a raised face (RF) coupling. 6. The magnetic flowmeter flowtube assembly of claim 4 , wherein the standard coupling is a ring-type-joint (RTJ) coupling. 7. The magnetic flowmeter flowtube assembly of claim 1 , wherein at least one of the first and second spring-energized seals includes a pair of sidewalls coupled together by an end and wherein a spring is disposed between the pair of sidewalls proximate the end. 8. The magnetic flowmeter flowtube assembly of claim 7 , wherein the pair of sidewalls and the end are formed of polytetrafluoroethylene (PTFE). 9. The magnetic flowmeter flowtube assembly of claim 7 , wherein the pair of sidewalls and the end are formed of the same material as the fluoropolymer liner. 10. The magnetic flowmeter flowtube assembly of claim 7 , wherein the spring is formed of 316L stainless steel. 11. The magnetic flowmeter flowtube assembly of claim 7 , wherein the spring is formed of the same material as at least one of the first and second lining protectors. 12. The magnetic flowmeter flowtube assembly of claim 7 , wherein each sidewall includes an outwardly extending member. 13. The magnetic flowmeter flowtube assembly of claim 1 , wherein the first lining protector is removably coupled to the first flange. 14. The magnetic flowmeter flowtube assembly of claim 13 , wherein the second lining protector is removably coupled to the second flange. 15. The magnetic flowmeter flowtube assembly of claim 1 , wherein the fluoropolymer liner includes a second flared portion disposed between the second lining protector and the second flange.
