Solids Strainer System For A Hydraulic Choke

US Patent:
2005000, Jan 13, 2005
Filed:
Jun 30, 2004
Appl. No.:
10/880640
Inventors:
Donald Sims - Houston TX, US
Michael Taylor - Tomball TX, US
Robert Schmidt - Cypress TX, US
David Schmidt - Houston TX, US
Joh McCaskill - Jersey Village TX, US
Assignee:
Power Chokes, L.P. - Cypress TX
International Classification:
E21B021/12
US Classification:
175209000, 175218000
Abstract:
The invention contemplates a strainer based upon a four-way, two-position rotary cylindrical plug valve having a hollow plug. The normal entry port for the sealing plug of the plug valve is a circular radial hole passing from the exterior of the plug into the interior cavity of the plug. The normal exit port for the sealing plug is a regular array of small holes across from and coaxial with the normal entry hole. The ports for the valve body are in two pairs positioned at 90° from each other, with the axes of the ports lying in the same transverse plane as the ports of the valve plug.

Flow System For A Hydraulic Choke Solids Strainer

US Patent:
7360611, Apr 22, 2008
Filed:
May 23, 2007
Appl. No.:
11/805328
Inventors:
Donald Glynn Sims - Houston TX, US
Michael James Taylor - Tomball TX, US
Robert Frank Schmidt - Cypress TX, US
David Anthony Schmidt - Houston TX, US
John Walton McCaskill - Jersey Village TX, US
Assignee:
Expro Americas, L.P. - Houston TX
International Classification:
E21B 21/06, E21B 21/10, B01D 35/02, F16K 11/085
US Classification:
175206, 175207, 175218, 166 7512, 166229, 137547, 13762532, 210422, 210309
Abstract:
A strainer system having two separate strainers positioned in parallel, where one strainer can be cleaned while still permitting normal flow through the other strainer. The system flow circuit is arranged so that a high pressure backwashing flow can be applied to one strainer while the other strainer is providing its normal straining function. The backwashed strainer is then isolated by valves so that its access flange can be removed and the particulate buildup within the valve plug cleaned out. The strainer is then returned to service following the replacement of the access flange. In this manner, it is possible to alternate between the two strainers so that continuous flow can be maintained to the hydraulic choke located downstream of the strainer system.
