A multilayered nonwoven insulating barrier with an integral pocket for installation of a component to be insulated. The insulating barrier has nonwoven layers that overlap one another and are stitched to one another by first pair of seams to form an integral pocket therebetween. An elastic member is secured to one end of the insulating barrier to facilitate wrapping the end around and forming a seal. A second elastic member is secured to an opposite end of the insulating barrier to facilitate wrapping the second end around and forming a seal. A releasable member is secured along a first lateral side of the insulating barrier and a mating releasable member is secured along an opposite second lateral side of the insulating barrier and the releasable members facilitate releasable wrapping of the insulating barrier about and forming a seal with the component.

The intersection connection of locomotive cryogenic systems includes a flexible double-wall corrugated pipeline having two corrugated pipes made of cold-resistant steel, which are arranged one inside the other and separated by elastic inserts. There are end adapter flanges fixed to the end walls of the locomotive adjacent sections, and an elastic bar connected to the flexible double-wall corrugated pipeline with suspensions. The intersection connection can be provided with an elastic bar aligned relative to the inner corrugated pipe with centering elastic inserts.

A line coupling having a housing which has a tube connection piece and a housing head. A passage duct extends from a first opening, which is formed by the tube connection piece, to a second opening, which is formed by the housing head. A tube connection structure is arranged in the passage duct. The tube connection structure is connected in a form-fitting manner via first coupling means to a first end of an inner tube which extends out of the housing head through the second opening. The section of the passage duct between the first opening and tube connection structure and inner tube form a flow duct for fluid. A container is also disclosed having a container housing which forms a container hollow space and a container opening. The container opening is formed by an outwardly projecting connection piece, and has a line coupling.

An apparatus for sealing an opening in a metal sheath surrounding an insulated pipe is provided, the apparatus including a base comprising an outer flange securable within the opening, and defining an inner passage therethrough, the base having an annular ridge extending into the inner passage; a flexible waterproof body positionable within the inner passage, the body having a periphery therearound and a groove located within the periphery adapted to engage around the annular ridge; and a flexible metal element within the base.

An apparatus and method for sealing an end cap on an insulated pipe system is provided. A flexible body having a top, a bottom, a first side and a second side acts to prevent the ingress of moisture into an insulated pipe system at the connection between the end cap and the pipe. The top of the flexible body has an end cap receiver. The bottom of the flexible body circumferentially engages the pipe. The flexible body is sealable to the pipe by a sealant. The end cap receiver accepts an edge of an end cap. A flexible band circumferentially engages the flexible body to hold the flexible body on the pipe.

A three-way pipe connector set for connecting pipes such as corrugated insulated pipes used for transporting hot water such as in central heating systems. The connector set can accommodate pipes of different diameter, and comprises a mating pair of a lid piece and bottom piece, each having three semi-circular edge portions that mate with the respective corresponding portions in the mating piece to form circular holes, the circular holes having adjacent edge grooves forming circular grooves when the pieces mate. The set includes at least two top hat pieces, each comprising a cylinder portion and a flange portion, the flange portion having an edge groove to fit an O-ring and configured to fit in a circular groove of the connector. Pipe gaskets are provided for each top hat piece that fit around a suitable pipe to form a tight seal between the pipe and connector.
