Abstract: The present invention regards a barrier plug system (3) for sealing off a pipe (1), comprising a plug body, a first and a second end plate surface (11, 31) arranged on opposite sides of the plug body and at least one circumferential sealing means (6) and means (8) for setting the plug system (3). The plug body comprises at least two separate plug body elements (10, 30) movable relative each other and the at least one sealing means (6) is arranged abutting two opposite annular pressing surfaces (12, 32) formed by the plug body, which are moved towards each other during setting of the plug system (3). The pressing surfaces (12, 32) are limited in the movement against each other by stop means and pre-tensioned to move toward each other by at least one tensioning device (7).

Abstract: A pipe plug comprised of two, pivotally connected plugging heads, each plugging head having a sealing element, which work in combination to double block and bleed a pipe. The first sealing element prevents flow of product in the pipe and the second sealing element captures any leakage past the first sealing element and forces that leakage out through a fitting. A stabilization pad, connected to a flange on a nosepiece of each plugging head, prevents deformation of the sealing elements. A spring-loaded pivot arm connected to the second plugging head allows the yoke that connects the two plugging heads to rotate freely. An outward-facing raised taper projection on the pivot arm, along with a guide wheel connected to the first plugging head, prevent the yokes and plugging heads from becoming entrapped during their installation in or removal from the pipe.

Abstract: A dual-purpose engine fitting is provided that may be used both during engine testing and during engine use, for vehicles with vacuum assisted brakes and for those without. The fitting has a body portion configured to fit within an opening in the manifold and defining a passage having opposing first and second ends. The fitting has a seal portion enclosing the first end of the passage. The second end of the passage is open to the manifold when the body portion is fit within the manifold. A thinned wall joins the body portion and the seal portion, establishing a predetermined fracture region at which the seal portion will separate from the body portion when sufficient torque is applied to the seal portion to thereby open the first end of the passage. A method of assembling vehicles is also provided.

Abstract: A pipe filter and closure assembly comprises a support member in the form of an annular collar or sleeve. In use the collar is positioned wholly within the pipe at some distance from an open (upper) end of the pipe. A filter element in the form of a strainer is releasably mountable to the collar so as to inhibit the passage of solid material through the pipe, whilst allowing the passage of fluids (liquids and gases) therethrough. A closure member in the form of a plug in use is mountable inside the collar to be seated at the strainer. In use when the plug is in place, the flow of material through the pipe is blocked. The location of the assembly or part thereof arrangeable wholly within the pipe reduces the ease of access to and presents significant difficulties for an operator seeking to tamper with the assembly.

Abstract: In a protector for protecting a trapezoidal female thread of a pipe formed to an end thereof, the protector has a male thread formed thereto so as to be threaded with the female thread as well as the height of the thread of the male thread is made larger than the height of the thread of the female thread. With this arrangement, a surface treatment applied to the surface of the female thread or a male thread formed to the end of the pipe can be prevented from being damaged, and in particular, a surface treatment applied to a guide flank surface, a load flank surface, a corner portion, and the like of the thread can be prevented from being subjected to wear, damage, and the like.

Abstract: A vacuum sealing-structure for a heat-sinking conduit/chamber which suits an upright heat-sinking conduit (thermal tower or thermal column), a laying flat heat-sinking chamber (thermal chamber or vapor chamber) and other like devices. The structure comprises: a hollow pipe (or chamber) of which one end is open; a sealing lid for covering the opening, the sealing lid having a hole thereon; and a screw for sealing to lock in the hole of the sealing lid. Therefore, when in slight screwing in of the screw to snuggle to the hole, air in the hollow pipe (or chamber) can be drawn out by an externally connected vacuum-forming equipment, after the hollow pipe (or chamber) is drawn to form the vacuum, the screw can be screwed in to tightly seal the opening of the hollow pipe (or chamber).
