Separating Seized Well Flanges
"Tree wellhead repairs" is an upstream operating companies' "key theme". So, do you need to remove bolted flanges, valve covers (bonnets), hub clamps and bolt less hub flanges on wellheads, which present real challenges in separating?
ThinJack is a unique service to separate seized well flanges where conventional techniques either do not work or are unsuitable. As well as separating the flange, the ThinJack's hydraulic power draws seized and rusty studs through the bolt holes and overcomes seal friction. It delivers hundreds of tons of controlled force, exactly where it is needed, which is significantly higher than from conventional hydraulic spreaders or the pulling-power of drill strings. ThinJack's hydraulic power can separate in any direction whilst protecting sealing faces and hanger necks. It is possible to jack within gaps an order of magnitude thinner than needed for any other system. With controlled and even flange separation, the likelihood that flange studs become tilted and jammed inside the bolt holes is minimised. ThinJack's hydraulic power is an intrinsically safe alternative to cutting and grinding tools. Human "power", improvised tools and methods "forced beyond their safe limits" are eliminated. ThinJack provides a rigless and crane less service, though some of our work is enhancing the pulling limitations of draw works, drill strings and their connections.
