The disclosure includes a method and apparatus for protecting an air vent pipe. In one or more embodiments, a cover can include a plurality of sidewalls and a pipe portal disclosed through at lease on of the side walls. The distal end of an air vent pipe can be disposed through the pipe portal and into the internal volume of the cover. A clamp can secure the cover to the air vent pipe. An access door disposed in a side wall can give access to the clamp and distal end of the air vent pipe and closing and locking the access door with a locking mechanism can prevent unauthorized users from accessing the distal end of the air vent pipe.

In embodiments, a connector for setting a layout of a brake hose includes a first coupling member coupled to one end of the brake hose; a second coupling member disposed to be spaced apart from the first coupling member, and coupled to the caliper housing or the frame of the master cylinder; and an adjusting unit connected at one end thereof to the first coupling member, connected at other end thereof to the second coupling member, and configured to adjust a shortest length between a bottom surface of the first coupling member and an outer circumferential surface of the second coupling member and to adjust a line passing through a center of the first coupling member with respect to the second coupling member to be positioned in one of up/down/left/right directions, in a test for setting the layout of the brake hose.

An in-line inspection tool for a pipeline includes a body that is propelled through the pipeline and a plurality of sensor assemblies mounted to the body. The sensor assemblies are distributed circumferentially about a central axis of the body with each sensor assembly configured to move through a range of radial positions in a respective radial direction. A first sensor assembly of the plurality of sensor assemblies includes a first elongate arm, a first sensor carried by the first arm, and a first spacer that extends from the first arm. A second sensor assembly of the plurality of sensor assemblies includes a second elongate arm and a second sensor carried by the second arm. The first spacer contacts the second arm and maintains an expected circumferential spacing between the first arm and the second arm over the range of radial positions as the body is propelled through the pipeline.

A pipe joint includes first and second sleeves having fluid flow paths communicating with each other; an annular gasket interposed between abutting end surfaces of the sleeves; a male screw member having a through hole into which the first sleeve is inserted; and a female screw member having a through hole into which the second sleeve is inserted, the sleeves being joined by screwing the male screw member with the female screw member, wherein the pipe joint has a leak port opened at a portion of the outer peripheral surface of the male screw member not covered by the female screw member and communicates with a gap between the male screw member and the first sleeve to detect a leak fluid leaked from gaps between the sleeves and the gasket.

The invention relates to an evaluation tool and method for inspecting the integrity of any physical industry connections (hereinafter fittings). The tool comprises a first component (21) provided with a recess (23) to facilitate its engagement with a fitting to be evaluated (see FIG. 10); and a second component (20) connected to, and moveable relative to, the first component (21). Movement of the second component (20) relative to the first component (21) establishes a measurement between two surfaces (32, 33 in FIG. 10) of a fitting (34) to be evaluated, e.g. between an adjustable ferrule or nut (32) and a fixed part (33) of a fitting (34). The measurement is directly (27, 28), or indirectly, indicative of one or more predetermined connection conditions (e.g. over or under tightening of the adjustable component). The predetermined connection conditions may be read directly from the tool, remotely via an electronic device, or by late cross-referencing against entries in a database.
