Fittings For Pipes, And Presses For Installing The Fittings To Pipes
A fitting for a pipe generally includes a saddle for coupling the fitting to the pipe and a tap for establishing fluid communication between the fitting and the pipe. The saddle defines a channel extending generally longitudinally through the saddle, and the channel is free of threads. And, the tap is configured to fit within the channel of the saddle for establishing the fluid communication between the fitting and the pipe.
Systems and methods for valve insertion and linestopping
The present embodiments provide systems and methods for valve insertion and linestopping. In one embodiment, the system comprises a sealing housing having a lower housing portion and an upper housing portion that are each dimensioned to partially surround an exterior surface of an existing pipe in an airtight state. In one embodiment, an integral valve assembly is disposed at least partially within an integral valve housing section of the upper housing portion. The integral valve assembly comprises a valve movable between an open position in which the valve provides an open pathway through an opening in the upper housing portion, and a closed position in which the valve provides a seal adjacent to the opening. The upper housing portion may be adapted to selectively receive each of an adapter plate for a cutting machine, a valve bonnet, and a blind flange. Optionally, the valve bonnet and the gate may be removed from engagement with the upper housing portion when the valve of the integral valve assembly is in the closed position, and a blind flange may be secured to the upper housing portion after the valve bonnet and the gate are removed. Therefore, the user advantageously has an option of whether to leave the valve bonnet and the gate coupled to the sealing housing for certain applications, or may remove the valve bonnet and the gate for other applications.
ARTICULATING DRILL METHOD AND APPARATUS FOR CUTTING OPENINGS IN NESTED STRINGS OF UNDERWATER PIPING AND OR TUBING FOR OVERTURNED WELLS OR PLATFORMS
A method and apparatus for angularly drilling during a tapping procedure 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.
Fittings for pipes, and presses for installing the fittings to pipes
A fitting for a pipe generally includes a saddle for coupling the fitting to the pipe and a tap for establishing fluid communication between the fitting and the pipe. The saddle defines a channel extending generally longitudinally through the saddle, and the channel is free of threads. And, the tap is configured to couple to the saddle within the channel of the saddle. A press for installing the fitting to the pipe generally includes a housing configured to releasably couple to the fitting, and a spike configured to releasably couple to the housing and extend at least partly through the fitting for piercing the pipe to thereby allow at least part of the fitting to be inserted into the pipe through the piercing in the pipe to thereby establishing fluid communication between the fitting and the pipe.
SPRAY NOZZLE MOUNTING FOR RECEIVING FLUID FROM DISTRIBUTION PIPE
A spray nozzle body has an upper end provided with a clamp arrangement comprising upper and lower clamp halves tightly clamped onto a fluid supply tube having a preselected first diameter. A removable tubular fluid delivery stem is received in a receiver hole extending vertically into the nozzle body from a clamping surface of the lower clamp half and has an upper end portion tightly received in a fluid outlet hole, of preselected size, provided in the supply tube. The clamp arrangement may be reconfigured for being clamped onto a smaller fluid supply tube by providing a replacement upper clamp half and a pipe-size adapter, each having appropriately sized clamping surfaces, with the adapter being seated within the clamping surface of the lower clamp half The pipe-size adapter incorporates a suitably dimensioned fluid delivery stem.
