Latest Patents
One of Donald R. Petrash's latest patents is the Diverter Flow Line Seal. This invention features a diverter body composed of an upper portion, a central portion, and a lower portion, which is secured to the upper end of a riser and lands in a housing. The central portion includes lateral flow openings that align axially with a lateral flowline outlet in the housing. A pair of identical gallery seals is positioned above and below the lateral flowline outlet. The upper gallery seal is situated between the upper portion, the central portion, and the housing. It consists of upper and lower metal rings with a central elastomer sandwiched in between. The elastomer's outer diameter seals against the housing bore, while the rings are symmetric and mated to the elastomer along S-shaped interfaces that form inward-facing shoulders. An annular cavity and flexible annular lips are created along the elastomer's inner diameter. A passage extends through the diverter bodies, allowing hydraulic fluid to be pumped through the passages to pressurize the cavities and energize the elastomers, effectively sealing against the bore.
