A method and apparatus for tapping into a pressurized multiple strings of coaxially situated tubulars for wells and/or platforms which have overturned wherein the tapping occurs underwater via a diver or remotely operated vehicle. The assembly includes a tapping tool connectable to the tubular via a saddle connection and an adjustable tapping clamp with adjustable support/locking feet, compression plate with view ports, and angularly adjustable hot tapping system, along with a drill/saw system.

A method of assembling a tapping sleeve includes positioning an outlet band on a pipe element with an arcuate portion of the outlet band contacting an outer surface of the pipe element, the outlet band including a front end, a back end, a first side end, a second side end, a first bend line defined between the first side end and the second side end and extending from the front end to the back end, a second bend line defined between the first bend line and the second side end and extending from the front end to the back end, wherein the outlet band defines an arcuate portion between the first bend line and the second bend line, a first flange defined between the first side end and the first bend line, and a second flange defined between the second side end and the second bend line.

Provided are an installation method and an installation device for a fluid control device capable of improving controllability of a fluid in a pipe by improving positional accuracy of a valve body inserted into a hole formed in a fluid pipe in a housing and decreasing the size, weight, and cost of construction equipment such as an operation valve device or an installation device of a fluid control valve.

A cut warning system can include a valve sleeve defining a cavity, the valve sleeve defining a bottom sealing surface within the cavity; a pipeline extending through the cavity; a drilling machine including a shell cutter, the shell cutter defining a bottom edge, the drilling machine configured to axially advance the shell cutter from a pre-engagement position towards the bottom sealing surface, the pipeline positioned between the shell cutter and the bottom sealing surface in the pre-engagement position; and a signaling element positioned within the cavity, the signaling element configured to produce a signal when the shell cutter reaches a post-engagement position, the bottom edge being axially positioned between the pipeline and the bottom sealing surface.

Systems, apparatus and methods for hot tapping into pressurized, coated duct systems for transporting corrosive substances are disclosed. A branch line may be installed in such systems without shutting down or depressurizing the system using the disclosed systems, apparatus and methods without compromising the system coating or resistance to corrosion from the transported substances. Cut edges created when ductwork is cut to install a branch line are captured and sealed between two gaskets, avoiding the need for recoating with difficult to apply corrosive protection materials such as fluoropolymer coatings.
