An example shut-off device includes a valve body to surround a section of a pipe and form a chamber about the section of the pipe. The example shut-off device also includes a first flange bearing on a first side of the chamber. The first flange bearing in a closed position forming a first seal between the pipe and the chamber. The example shut-off device also includes a second flange bearing on a second side of the chamber. the second flange bearing in a closed position forming a second seal between the pipe and the chamber. The example shut-off device also includes a cutting blade in the chamber. The cutting blade tightens against the pipe to cut through the pipe and at least partially seals an opening in the cut pipe. The cutting blade is configured to operate as a gate valve.

An adaptive sealing device for pipeline porous leakage. The device includes a pressure protection device and an encircling sealing rubber cover. The pressure protection device is used to pressurize and seal the pipeline by the encircling sealing rubber cover. The device further includes a control mechanism connected with the pressure protection device for adjusting the sealing pressure of the pressure protection device on the pipeline. The device further includes an anti-retraction mechanism connected with the pressure protection device and the control mechanism for limiting the pressure protection device and/or the control mechanism.

A device for repairing pipelines comprises a sleeve adhered to a pipeline, said sleeve being made of a cured composite material in the form of a truncated cone with a cylindrical passage passing along an axis, the diameter of the passage being equal to the outer diameter of the pipeline being repaired, and a side wall, the inner surface of the side wall corresponding to the outer surface of the sleeve, wherein the side wall is made of a cured composite material. The invention provides improvement of performance reliability of the repaired pipeline.

The present invention provides an adjustable clamp apparatus having curved arms which pivot/articulate relative to each other. The distance between pivot points can be adjusted via specially configured couplers having nuts and threaded rods. The curved arms can be locked together with a rod placed in a slot, and then squeezed by rotation of threaded rod. In the interior of the curved arms there can be a plurality of projections or contact points. A strap can be connected to a selected adjustable clamp (e.g., by a pair of padeyes) and used to raise and lower the clamp. When being lowered onto a pipe to be repaired, the curved arms can be open wide and when their upper portions make contact with the pipe to be repaired, this contact will tend to cause arms to close around the pipe relative to each other. Once clamped against the pipe with the clamps, the repair members can be welded together.

A crimping ring is used for securing a fitting within a tube. The crimping ring comprises a metallic ring and an indicator. The metallic ring has a radially inward surface and a radially outward surface. The indicator is applied to at least a portion of the radially outward surface of the metallic ring and visually indicates a dimensional state of the crimping ring to a user.

Seal assembly 100, useful for repairing an uncontrolled surface such as pipeline 110, comprises seal 102 which is subjected to pressure and temperature and remains operable under, e.g., subsea conditions. Seal assembly 100 is capable of sealing pipelines of diameters up to 48 inches. Seal assembly 100 is actuated/energized by axially compressing/loading seal assembly 100 between one or more controlled surfaces and an uncontrolled surface and can be used for repairing and providing sealing in flowline or pipelines of either subsea or other petrochemical industries where the pipelines. Spool assembly 700 comprising seal assembly 100 may be used to repair a damaged pipeline section after the damaged section is removed to provide a sealed replacement fluid path for the pipeline.

Some embodiments of the present disclosure include a tool set for the installation and removal of a gasket from a hose. The tool set may include a gasket insertion tool configured to install a gasket on a hose, the gasket insertion tool being self-centering and having a plunger foot configured to install the gasket onto the hose. The tool set may also include a gasket removal tool configured to remove a gasket from a hose, the gasket removal tool being self-centering and including at least one blade configured to grab onto the gasket to remove the gasket from the hose.

The present disclosure describes a device for leak containment, including a set of compression plates, which respectively contain fixed thereto a plurality of fixing clamps for anchoring the device, and a plurality of tightening elements including screws and nuts, at least one filling element, a set of hollow tubular elements, and a tensioning cable passing inside the set of hollow tubular elements. A tensioning of the tensioning cable, together with a tightening of the plurality of tightening elements, presses the set of hollow tubular elements and compresses at least one filling element.

A clamp saddle for attachment to a pipe clamp that allows the clamp to be used for plugging leaks in different diameters of pipe is disclosed. The clamp saddle includes a semi-circular main body that is conformed to a specific pipe diameter. An attachment mechanism on the main body that interchangeably connects to an arm of a clamp. A different diameter clamp saddle may replace the initial saddle to allow the clamp to be used for a different diameter pipe.
