Local Degraded Area Repair And Restoration Component For Pressure Retaining Items
US Patent:
2002012, Sep 19, 2002
Filed:
Mar 14, 2002
Appl. No.:
10/098776
Inventors:
Paul Manzon - Pottstown PA, US
International Classification:
F16L055/18
US Classification:
138/099000, 138/097000
Abstract:
What is new in the art to which my invention pertains is that it allows for a repair or restoration of a pressure retaining item that has local material degradation to an acceptable state of condition for continued operation without the need to cut out the degraded section of material or breach the pressure boundary of a pressure retaining item. Common methods of repair include removal of degraded or affected material section and replacement with a new section of equivalent material by joining the new material to an existing item at a location of adequate thickness using full or complete penetration welds. This type of repair may be referred to in the industry as a “flush patch repair”. An additional type of repair where a section of material degradation may be localized is a “weld build-up repair” wherein weld metal is deposited onto the existing area of affected material to return the material to its original thickness. Both “flush patch repair” and weld build-up repair” methods require breaching of the pressure boundary integrity of a pressure retaining item to implement a repair. The invention does not require breaching a pressure boundary.
Access Component For Pressure Retaining Item (Pmcap-Nozzle)
US Patent:
2006010, May 25, 2006
Filed:
Oct 29, 2004
Appl. No.:
10/978251
Inventors:
Paul Manzon - Pottstown PA, US
International Classification:
F16L 41/00
US Classification:
285197000
Abstract:
This application is for an access opening component (invention) used to provide access into a pressure retaining item. Pressure retaining item may contain degraded material at the location where the invention is to be located. What is new in the art to which my invention pertains is that installation of the access opening can be accomplished without need to cut a precise hole in the pressure retaining item or remove localized degraded material. Common access hole installation methods require cutting a precise size hole and may require removal or repair of degraded material in the pressure boundary material. The invention does not require replacement or repair of degraded pressure boundary material, and does not required cutting a precise hole size in the material as the invention can be constructed to encapsulate any area of degraded pressure boundary material or any size hole cut into the pressure boundary material.
