An inflatable, balloon-type catheter apparatus which is conformable to fit most all intake and exhaust systems to delivery pressure (with or without smoke) to test the fluid integrity of the fluid system. The device is configured to be inserted into the canal of the intake or exhaust system and inflated to seal off the fluid system. The pressurized smoke is passed through the inflated inlet adapter to test for leaks.

A pipeline pressure isolation system that can have a multi pressure head plug module, a hydrotest module and/or a multiwedge pipe interface.

An apparatus includes a blind flange and a clamp configured to clamp the blind flange to a pipe flange in sealing engagement. The clamp includes a body and a latch. The body is configured to extend around the blind flange and the pipe flange and includes a first portion and a second portion movable with respect to the first portion. The latch is configured to secure the body on the blind flange and the pipe flange. The clamp also includes a plurality of wedges spaced circumferentially about the body and rotatably connected thereto. The latch is selectively adjustable to move the first portion of the clamp body towards the second portion of the clamp body such that the plurality of wedges engage respective outer surfaces of the blind flange and the pipe flange to press the blind flange against the pipe flange.

A test cock is configured to connect to a test cock port. The test cock includes a body portion defining a flowpath between a distal end and a proximal end. The test cock includes an intake stem at the proximal end that has external threads to connect the test cock to the test cock port. The intake stem defines an intake opening connected to the flowpath, the intake opening having a non-circular shape, such as a hexagonal shape. The test cock also includes an extraction tool having an end forming the non-circular shape of the intake opening, the end being sized to fit within and engage the intake opening.

The disclosure relates to a gripping plug for use in a pipe wherein the pipe defines an inside radius, having: a wedge cone; a first plurality of discrete gripping devices slidably engaged with the wedge cone; a second plurality of discrete gripping devices slidably engaged with the wedge cone; a first plurality of studs connected to each of the first plurality of discrete gripping devices, where each of the first plurality of studs define a first stud length; and a second plurality of studs connected to each of the second plurality of discrete gripping devices, wherein each of the second plurality of studs define a second stud length.

Techniques for implementing and operating a system that includes a pipe segment, which has tubing that defines a bore and a fluid conduit implemented in an annulus of the tubing, and a test head. The test head includes a shell, which defines an annulus cavity, and an inflatable bladder implemented in the annulus cavity, in which the system maintains the inflatable securing bladder in a less inflated state while pipe segment tubing is not present in the annulus cavity and increases inflation of the inflatable bladder to a more inflated state when the tubing is present in the annulus cavity to facilitate securing and sealing an open end of the pipe segment in the test head to enable integrity of the tubing to be tested at least in part by flowing a test fluid into the annulus of the tubing via a testing port on the shell.

Techniques implementing and/or operating a system includes a pipe segment and a test head assembly secured to the pipe segment. The pipe segment includes tubing that defines a pipe bore through the pipe segment and a fluid conduit in a tubing annulus of the pipe segment. The test head assembly includes barrier material poly welded to the tubing of the pipe segment to facilitate sealing the fluid conduit defined in the tubing annulus from environmental conditions external to the tubing of the pipe segment and a fluid port fluidly connected to the fluid conduit defined within the tubing annulus to enable integrity of the tubing to be tested at least in part by flowing a test fluid into the fluid conduit defined in the tubing annulus via the fluid port, extracting fluid from the fluid conduit defined in the tubing annulus via the fluid port, or both.

A weld test plug has a flange; an actuator rod mounted to the flange, the actuator rod having: a part expander; an annular seal; and an axial stop; in which the actuator rod is connected to, during use, cause the part expander to actuate: the axial stop to move in a radially outward direction relative to the actuator rod; and the annular seal to radially expand and abut the axial stop. A method includes inserting an actuator rod into an open end of a vessel, the actuator rod carrying an annular seal, and an axial stop; sealing the open end of the vessel around the actuator rod; operating the actuator rod to actuate: the axial stop to move in a radially outward direction relative to the actuator rod; and the annular seal to radially expand to abut the axial stop and seal against an inner circumferential surface of the vessel.

Techniques for implementing and/or operating a system, which includes a pipe segment and a test head assembly. The test head includes an end container, in which an end of tubing of the pipe segment is disposed within the end container, an annulus seal implemented at least in part by solidifying fluid hardening material that is flowed into the end container to facilitate securing the test head assembly to the pipe segment and sealing an opening end of a tubing annulus of the pipe segment within the test head assembly, and a fluid port fluidly connected to a fluid conduit defined within the tubing annulus of the pipe segment to enable integrity of the tubing to be tested at least in part by flowing a test fluid into the fluid conduit defined in the tubing annulus, extracting fluid from the fluid conduit defined in the tubing annulus, or both.
