One aspect of the invention provides a system including: a length of energy-dissipative tubing; a first sealing device coupled to a first end of the length of energy-dissipative tubing; and a second sealing device coupled to a second end of the length of energy-dissipative tubing. Exposure to one or more selected from the group consisting of: fault currents or lightning strikes at an exposure point along the length of energy-dissipative tubing will produce arcs at the exposure point and at least one of the first end and the second end.

Disclosed is a fitting (1) for use with corrugated tubing (2) having a series of peaks (3) and valleys (4). The fitting (1) comprises a nut (5) having a passage (6) therethrough for receiving the tubing (2) and at least one retainer (7) arranged in the nut (5), wherein the retainer (7) has a retainer sealing surface (8) for placement in a valley (4) of the corrugated tubing (2). The fitting (1) further comprises a body (9) having a pointy annular body sealing edge (10) arranged so that the apex (11) of the body sealing edge (10) is pressed against the retainer sealing surface (8) when the nut (5) and the body (9) are forced toward each other. A method for connecting corrugated tubing (2) to a fitting (1) comprising a nut (5), a retainer (7) and a body (9) and use of a fitting (1) is also disclosed.

A pipe joint and elongated cementitious pipe is formed by joining abutting ends of adjacent pipe sections with a fiber reinforced composite material without the need for the pipe sections to have other connection means, such as the standard bell and spigot end connections. Also disclosed is a cementitious pipe including at least two cementitious pipe sections having ends that are joined together with a fiber reinforced polymer composite material. The cementitious pipe sections and resulting cementitious pipe may have a substantially uniform wall thickness and substantially uniform inner and outer diameters near the opposite ends of the pipe sections. Also provided is a method for joining cementitious pipe sections with a fiber reinforced composite material to manufacture an elongated cementitious pipe, such as an elongated concrete pipe.

A method for installing pipeline segments within a conduit. The method includes a step of securing a first pipe segment of the pipeline segments at a top end of the conduit, a step of aligning a main axis of a second pipe segment of the pipeline segments with the main axis of the pipeline, a step of lifting the second pipe segment from a first position associated with a bottom end of the conduit to a second position adjacent to the first pipe segment, a step of abutting a top rim of the second pipe segment against a bottom rim of the first pipe segment, and a step of attaching the top rim of the second pipe segment to the bottom rim of the first pipe segment.

A toilet assembly includes a toilet, a non-vitreous fluid delivery component, and a connector assembly. The non-vitreous fluid delivery component is coupled to, and in fluid communication with, the toilet. The connector assembly couples the non-vitreous fluid delivery component to the toilet in a substantially watertight manner. The connector assembly includes a connector body, a nut adjustably coupled to the connector body, and a sealing member disposed on the connector body. The nut is configured to be adjusted relative to the connector body to cause the connector body to compress the sealing member against a portion of the toilet, such that the sealing member creates a substantially watertight seal between the toilet and the connector body.

A hose assembly includes a corrugated metal tube having a plurality of corrugations and an outer cuff portion extending from an endmost one of the plurality of corrugations, radially outward of an inner diameter of the endmost corrugation, an end connection having an outer end defining a fluid connector and an inner end defining a nose portion received in the outer cuff portion of the corrugated metal tube, and a collar surrounding the outer cuff portion of the corrugated metal tube and the nose portion of the end connection. The collar, the outer cuff portion, and the nose portion are welded together.

A coupling apparatus for a corrugated hose, having a receptacle part for receiving the corrugated hose and a locking part, mounted on the receptacle part, for locking the corrugated hose in the coupling apparatus, wherein the locking part has a resiliently deformable engaging element for interlocking engagement in a corrugation of the corrugated hose, the receptacle part having a receptacle region for receiving the engaging element, wherein the coupling apparatus can be brought by means of a movement of the locking part relative to the receptacle part from an unlocked state, in which the engaging element is arranged outside of the receptacle region, into a locked state, in which the engaging element is arranged within the receptacle region such that the receptacle region blocks a movement of the engaging element in a radial direction of the coupling apparatus, and vice versa.

A pipe device includes a pipe and a connection element. The pipe has a pipe jacket that has an inner surface and an outer surface and forms a flow channel. The connection element forms a through-channel that extends from a connection piece consisting of a first material (M1) and having a first opening to a second opening. The pipe jacket is positioned on the connection piece with a first pipe end consisting of a second material (M2). A bonded connection is formed between the first material (M1) and the second material (M2) in a contact region between the inner surface of the pipe jacket and a peripheral surface of the connection piece.

A pipe joint connecting a first pipe having conductivity and being grounded and a second pipe including a corrugated metallic pipe member and a conductive layer having lower electric resistance than metal forming the pipe member and covering the pipe member, the pipe joint including a connection part that has conductivity and is connected to the first pipe, a housing part that has conductivity, is engaged with the connection part, and houses the second pipe inside the housing part by insertion of the second pipe along an axis direction of the second pipe, and a conductive member that includes a first part in contact at least partially with the housing part and a second part exposed to an outside of the housing part to be in contact with the conductive layer.

A flanged duct blank has a male part defined by lead notches formed at each side of a leading end and has a female part defined by trail notches formed at each side of a trailing end. The male part includes a lock tab. The female part includes a leg part and a Z-bend. The Z-bend includes a leg part and a gap. The duct blank is repeatedly clamped and bent by a pivoting wiper to form a duct portion. The pivoting wiper includes a clench tool that has a retractable rib and a retractable roller. With the lock tab inserted into the Z-bend and the retractable rib engaged with the Z-bend, the retractable roller clenches the leg part over the lock tab to lock the male and female parts together in a duct seam.
