A cleanout system and method for removal of metal debris from a fluid flow, such a flow of re-circulated drilling mud employs one or more magnetic unit positioned in the path of the fluid for collecting metal particles from the flow. The magnetic unit has a removable magnet core positioned in a non-magnetic sleeve. When the core is removed from the sleeve the attracted metal particles are allowed to drop from the sleeve under gravity to facilitate their collection and disposal. A fluid deflector is positioned upstream from each magnetic unit, protecting the magnetic unit from direct impact by the strong flow. The magnetic units are allowed to pivot from side-to-side and adjust their position in the flow.
A cleanout system for removal of metal debris from a fluid flow, the system comprising at least one magnetic unit configured for positioning in a path of the fluid, said at least one magnetic unit comprising a hollow sleeve, a removable magnetic core configured for positioning in said hollow sleeve, at least one fluid deflector member positioned upstream of said at least one magnetic unit, said fluid deflector member modifying the fluid flow adjacent said at least one magnetic tool unit, an upright shaft and a pivot sleeve detachably pivotally mountable on said shaft, said pivot sleeve being attached to said hollow sleeve, and wherein said upright shaft carries a transverse pivot sleeve stop to allow a bottom of said pivot sleeve to rest on said stop above said base plate.
A cleanout system for removal of metal debris from a fluid flow, the system comprising at least one magnetic unit configured for positioning in a path of the fluid, said at least one magnetic unit comprising a hollow sleeve and a removable magnetic core configured for positioning in said sleeve, and wherein said magnetic core comprises a handle detachably secured to an end of said magnetic core to facilitate removal of said magnetic core from said sleeve upon demand.
A cleanout system for removal of metal debris from a fluid flow, the system comprising at least one magnetic unit configured for positioning in a path of the fluid, said at least one magnetic unit comprising a hollow sleeve and a removable magnetic core configured for positioning in said sleeve, and wherein said hollow sleeve is provided with a means for preventing an upward movement of the metal debris settled on said hollow sleeve when said magnetic core is removed from said hollow sleeve.
A cleanout system for removal of metal debris from a fluid flow, the system comprising at least one magnetic unit configured for positioning in a path of the fluid, said at least one magnetic unit comprising a hollow sleeve and a removable magnetic core configured for positioning in said sleeve and wherein said magnetic core is provided with an internally threaded cutout at each end thereof.
A cleanout system for removal of metal debris from a well bore re-circulating fluid, the system comprising:
A method of removing metal debris from a fluid flow, the method comprising the following steps:
