Unbonded reinforced plastic pipe
Pipe body for an unbonded reinforced thermoplastic pipe (uRTP), the pipe body including a fluid retaining liner, an intermediate layer located radially outwardly of the fluid retaining liner, and a protective sheath located radially outwardly of the intermediate layer. The pipe body includes an end portion for terminating the pipe body at an end fitting. At the end portion, the intermediate layer is bonded to the fluid retaining liner. Away from the end portion, the intermediate layer remains unbonded to the fluid retaining liner.
FLEXIBLE PIPE END PORTION CONNECTION STRUCTURE
A flexible pipe end portion connection structure is provided. The flexible pipe end portion connection structure includes a flexible pipe body and a joint. The joint includes a first end and a second end opposite to each other and has a channel extending through the joint in a direction from the first end to the second end. An inner sidewall of the first end of the joint has a plurality of first stepped structures, and an inner diameter of a portion of the channel corresponding to the first stepped structure gradually decreases in the direction from the first end to the second end. At least a part of an end of the flexible pipe body is inserted into the first end of the joint to fit with the first stepped structure.

Attachment device for a hose arrangement
An attachment device, comprising a first line connector with a first fluid passage and a second line connector. The second line connector surrounds the first line connector such that a second fluid passage is created between the first line connector and the second line connector. The second fluid passage is fluidically separated from the first fluid passage. The second line connector can be pushed onto the first line connector from the end thereof situated opposite the hose attachment of the first line connector. The attachment is arranged in a line comprising the attachment device connected using a corresponding connection method.

Tool for securing a clamp
A tool for securing a clamp having a band and a clip is provided. The tool includes a base member and a first handle coupled to the base member. A cinching handle is rotationally coupled to the base member adjacent the first handle. A crimping handle is rotationally coupled to the base member adjacent the first handle opposite the cinching handle. A holding means is provided for holding the clip. A tensioning means is provided for moving a tab end portion of the band through the clip, the tensioning means being operably coupled to the cinching handle. A crimping means is provided for locking the clip to the band, the crimping means being operably coupled to the crimping handle. A severing means is provided for severing the tab end portion from the band, the severing means being operably coupled to the crimping handle.
GARDEN HOSE WITH METAL SHEATH AND FABRIC COVER
A garden hose has an inner tube for conveying water at domestic water pressure from a first coupler disposed at a first end of the inner tube to a second coupler disposed at a second end of the inner tube, the inner tube being waterproof and flexible, the first coupler adapted to threadedly connect to a conventional water faucet and the second coupler adapted to threadedly connect to a conventional garden appliance. The hose has a metal sheath disposed over the inner tube and extending from the first coupler to the second coupler, the flexible metal sheath having a first shoulder near the first coupler and a second shoulder near the second coupler, the metal sheath being flexible, and a fabric sheath disposed over the metal sheath and fixed to the metal sheath by a first constricting band disposed at the first shoulder and a second constricting band disposed at the second shoulder.

Layered tube and layer for use in same
A layer for directing a hydraulic fluid includes a first fluoropolymer, a first crosslinker, and an anti-static additive. The first fluoropolymer is present in an amount greater than 60 parts by weight, the first crosslinker is present in an amount of from about 1 to about 10 parts by weight, and the anti-static additive is present in an amount of from about 0.4 to about 4 parts by weight, each based on 100 parts by weight of the layer. The layer may be included in a layered tube. In addition to the layer, the layered tube also includes an outer layer. The outer layer includes a second fluoropolymer, which is the same as or different than the first fluoropolymer. The second fluoropolymer is present in an amount greater than 60 parts by weight based on 100 parts by weight of the outer layer.
