A pipe section, such as a pipe elbow, coated with a ceramic coating containing a fusible link displaced within. The link includes two exposed testing leads which are connected to a sensor which sends a signal across the link. Over time, the pipe section and the coating are worn away by material flowing through the pipe. Eventually the fusible link is severed due to the wear, signaling the sensor to send an alert, notifying that the pipe section needs to be replaced. The method of manufacture includes coating a standard pipe section with a ceramic coating, displacing a fusible link therein, and curing the coating. The coating may contain any number of fusible links in any conceivable arrangement.

A sleeve, which may be used to protect against bursting from hydraulic or other pressurized hoses and tubes, is disclosed. A method of installing such sleeves and a burst protection system are also disclosed.

A cleanout cover including a mounting ring that is secured to a surface surrounding an opening in a wall or floor through which the cleanout is accessed. Said mounting ring contains means for engaging with a separate dome-shaped cover with complementary engaging locking tabs and slots. The mounting ring is first attached to the adjacent surface. Next, the cover is locked into place over the mounting ring thus forming a fully functioning cleanout cover that does not directly engage with the cleanout plug. When the user desires to access the plumbing system, they simply twist the dome cover in the opposite direction and unlock the tabs located on the cover from the complementary slots located on the mounting ring. The dome cover is thereby removed and the cleanout plug is accessible through the wall.

An apparatus for increasing the utility of gravity conduits by using their underutilized headspace for pressurized conveyance.

Example air ducts comprising pliable tubular sidewalls are provided with example internal frameworks that hold the duct in a generally expanded shape even when the duct is depressurized. The framework tensions the pliable sidewall material along the length of the ducts to keep the material taut. In some examples, the framework is restrained within the duct such that the duct's sidewall, being in tension, holds the framework in compression longitudinally. Thus, in the longitudinal direction, the duct is in tension and the framework is in compression. To prevent the framework from buckling under the compressive force, some example frameworks comprise a central longitudinal shaft with a plurality of radial spokes and rings that help hold the shaft straight. In some examples, the rings also help hold the duct radially expanded.

Pliable-wall air ducts with internal expanding structures are disclosed. An example air duct system includes a shaft to be disposed within an air duct, to extend in a longitudinal direction, and to be in longitudinal compression. The air duct system also includes a plurality of ribs to be coupled to the shaft and to engage an inner surface of the air duct and a spring to be disposed within the air duct, the spring to be coupled to the shaft. The spring under stress being a contributing factor in both the shaft being in longitudinal compression and the air duct being in longitudinal tension.

A pipe restraint assembly includes a restraint body configured to be removably attached to a portion of pipe. The portion of pipe is associated with a postulated pipe failure associated with a release of high pressure fluid. A plurality of apertures penetrate through the restraint body and are positioned proximate to a location of the postulated pipe failure. The apertures are configured to provide a number of passageways for the fluid to exit from the location of the postulated pipe failure and to be released outside of the restraint body. One or more restraint devices maintain the position of the apertures relative to the location of the postulated pipe failure.

Systems and methods herein are for hose management in a computing module. A rotatable support structure includes a moveable inset structure and is to support rotation movement of cooling hoses that are to cool underlying devices in the computing module, where the rotation movement is about an axis of the computing module to allow the cooling hoses to be moved away from the underlying devices of the computing module and where the movable inset structure is movable within the rotatable support structure to receive tension on the cooling hoses from being coupled to a manifold of the computing module.

A limit stop for limiting the effect of severe accident consequences on process equipment connected by pipelines passing through walls. The stop may be used, in particular, in the nuclear industry. The limit stop installed in a protective wall. The stop is made in the form of an anchor with horizontal grooves and an insert into the pipeline with horizontal teeth. The anchor is mounted on a protective wall. The insert is installed on the pipeline from the outer side of the protective wall. The anchor and insert are made with the possibility of locking the teeth in the grooves during torsion. The insert is provided with a postulated break site.
