The present invention is an elastic (mechanically stretchable), sanitizing pouch configured to receive and hold an Electronic Device of a predetermined configuration. The elasticity of the fabric used maximizes surface contact with the Electronic Device and the closeness of the fabric of the invention with the outside surfaces of the Electronic Device. A liftable and removable cover flap on the front of the invention is used to hold and access the inside of the invention. The back of the invention includes at least one pocket. The invention further includes a pull tab to help lift an Electronic Device out of the invention. While inside the invention, the silver ions are released in the fabric and inhibit the colonization of bacteria, viruses and fungus on the Electronic Device.

The invention relates to a hydraulic proof test assembly comprising at least a valve (1) with parallel seats (102). It comprises:

a shut-off member (2) with parallel plates (20, 21), connected by connecting means for regulating their separation, to make them go from a first position in which this separation is sufficient to enable the shut-off member (2) to be introduced into said valve (1) to a second position where said separation is greater, this separation making it possible to apply them firmly against said parallel seats (102);

a device (3) for inserting said shut-off member (2) into said valve (1) which comprises at least a “U” shaped tool, configured to be introduced into said valve (1), its parallel arms forming guides, while its base forms a support for retaining said shut-off member (2);

a “dummy stem” (4).

A structure including: a straight pipe made of a polyolefin-based material; a pair of ridges made of a polyolefin-based material, extending in a circumferential direction along an outer surface of the straight pipe, and spaced apart from each other in an axial direction of the straight pipe; a piping material including a plurality of metal-made separate cases, which are separated from each other in the circumferential direction of the straight pipe and enclose a portion of the straight pipe; and a pair of engagement portions formed on at least one of the separate cases and engaging respectively with the pair of ridges.

A trench-less plug assembly having a fluid release element, further including: a top retaining ring, a bottom retaining ring, a plurality of rods vertically connecting the top retaining ring to the bottom retaining ring. A retaining plug is adapted to traverse vertically along the plurality of rods, and a main fitting adapted for receiving the bottom retaining ring. A gasket is disposed between the main fitting and the retaining plug. The plurality of rods engage the retaining plug with threads, whereby the retaining plug is positioned vertically between the top retaining ring and the bottom retaining ring by rotational movement of the retaining plug. The main fitting is adapted to attach to a main pipeline, and the main fitting is adapted to receive a riser enclosing the fluid release element. In one example, the main fitting attaches to a main pipeline using a saddle.

The present disclosure provides an isolation tool for isolating a section of pipe or a vessel and methods for isolating a section of a pipe or a vessel. In particular, the present disclosure provides a double isolation and bleed (DIB) isolation tool, for use in line-stopping operations and methods of line isolation employing the isolation tool.

A pipeline plug includes a plug body. The plug body includes an outer housing. The interior of the outer housing defines a pressure vessel. The pipeline plug includes a pressure head coupled to the plug body, a seal assembly, a gripper assembly, a movable head, and an actuation mechanism. The actuation mechanism includes a leadscrew, the leadscrew coupled to the movable head. The actuation mechanism includes a captive nut, the captive nut positioned within the pressure vessel. The actuation mechanism includes a motor, the motor operatively coupled to the captive nut and adapted to rotate the captive nut.
