Safety hoses protected by wire mesh and an apparatus for manufacturing them are disclosed. The hose assembly has an inner flexible tube, wrapped with two helices made of ribbons of woven, wire mesh. An outer flexible tube is fitted over the helixes. The ribbon is woven from metal fibers having a diameter of less than 0.20 mm and open apertures of less than 0.45 mm. The ribbon is preferably made of bias-cut material and the pitch of the helixes is such that the warp threads of the ribbons overlap at an angle between 15 and 33 degrees. Alternately the hose may be ribbon braided, having two or more ribbons of woven wire mesh braided together over the inner tube. A modified May pole braiding machine to accomplish such ribbon braiding is disclosed.

Methods and systems for delivering a voltage signal to remote equipment associated with a hydraulic system are disclosed. One method includes actuating an output voltage from a control panel at an electronic control output electrically connected at a socket positioned on a first end of a hose assembly, the hose assembly having a conductive layer electrically connected to the socket and extending the length of the hose assembly and also electrically connected to a second socket at a second end of the hose assembly. By actuating the output voltage, the output voltage is delivered to remote equipment at the second end of the hose assembly that is electrically connected to the second socket.

A multilayer tube, particularly for fluids is provided with an internally hollow shape and includes a co-extruded sheath made of fluorinated polymers such as FEP, MFA, PFA, ECTFE and PTFE, located in the innermost layer. The sheath is constituted by an internal substrate made of non-pigmented virgin material and by an external substrate made of pigmented material.

A tube for hot food fluids includes an inner layer made of hydrogenated nitrile rubber (HNBR), one or more intermediate layers, and an outer covering layer made of elastomeric material. For example, the outer covering layer could be made of HNBR. One or more of the intermediate reinforcement layers include at least one textile reinforcement layer that is resistant to high temperatures. One or more of the intermediate reinforcement layers may further include two layers of textile reinforcement resistant to high temperatures, with the interposition of a filler layer made of elastomeric material.

A vulcanization-adhered laminate is constituted by a structure where a fluororubber layer and a synthetic rubber-containing layer are tightly adhered by vulcanization by vulcanization, and the synthetic rubber layer prior to the vulcanization-adhesion includes organic peroxide, silica, organic phosphonium salt, maleic anhydride-modified polybutadiene, and magnesium oxide.

Hoses include an inner tube, a reinforcement layer disposed outwardly from the inner tube, and a cover layer disposed outwardly from the reinforcement layer, where the cover layer and/or the inner tube include(s) a composition having a sustainable content. The composition includes one or more ethylene derived sustainable polymers. The one or more ethylene derived sustainable polymers is formed of ethylene monomer derived from one or more renewable sources. The one or more ethylene derived sustainable polymers may be one or more of PVC sustainable polymer, EPDM sustainable polymer and EPR sustainable polymer.

Provided are a hose excelling in a lightweight property and in fatigue fracture resistance, a method for manufacturing the hose, and a hydraulic pump. The hose includes a tube, an interior of the tube being hollow, continuous carbon fibers and/or continuous glass fibers wound around an outer circumference of the tube, and a thermosetting resin present external to the tube. The thermosetting resin has an elastic modulus from 0.5 to 10 MPa, and the continuous carbon fibers and/or continuous glass fibers are impregnated with at least a part of the thermosetting resin. The elastic modulus of the thermosetting resin is a numeric value determined by: heating the thermosetting resin for 2 hours at a curing temperature of the thermosetting resin; then subjecting the thermosetting resin to thermoregulation for two weeks under a condition of a temperature of 23 C. and a relative humidity of 55%; and then performing a measurement in accordance with JIS K7161:2019.

The present application relates to a fluid hose for conducting fluid, wherein the fluid hose is adapted as an at least two-layer fluid hose, which comprises an inner hose layer and an outer hose layer, wherein the inner hose layer encloses an interior of the fluid hose for receiving fluid, wherein the inner hose layer comprising an inner surface facing the interior of the fluid hose, wherein the inner hose layer is formed from a plastic, wherein a surface-modifying substance is embedded within the plastic in a diffusion-resistant manner; and wherein the surface-modifying substance is adapted to change a surface property of the inner surface of the inner hose layer, in order to prevent colonization of the inner surface by microorganisms.

Systems and methods are disclosed that include providing a tubing construction with at least one layer formed from a thermoplastic vulcanizate (TPV). The tubing construction is suitable for use in pump applications subjected to cyclic loading and unloading. The tubing construction maintains a flowrate stability of +/10% for an extended period of time to provide consistent fluid dispensing and/or dosing for an extended life of the tubing construction and/or the fluid pump.

An article such as a multilayer hose includes at least one layer formed from an elastomeric composition including one or more polychloroprene elastomer(s); and a sustainable vulcanizing agent adapted to cure the one or more polychloroprene elastomer(s), the sustainable vulcanizing agent being at least partially derived from a sustainable source of treated dregs, and having a composition comprising, in % by mass based on the sustainable vulcanizing agent: 25%-50% CaO, 2% to 20% MgO, and 20% to 40% ZnO.
