Abstract
A dielectric fitting (10, 10′, 110) assembly includes a hose (14, 114) connected between two end fittings (12, 121, 112), and a structural reinforcement portion having at least an inner layer (26, 26′,126) formed of a first composite material having a high strength and a second composite material having a high electrical resistance. The first and second composite materials cover the assembly and provide a smooth transition of radial stiffness as the inner layer transitions from a high strength portion to a high electrically resistant portion.
Claims20
A dielectric fitting assembly comprising:
- an assembly including a hose connected between two end fittings;
- and
- a structural reinforcement portion having at least an inner layer formed of at least different first and second composite materials, the first composite material having a high strength relative to the second composite material and the second composite material having a high electrical resistance relative to the first composite material, the first and second composite materials covering the assembly and providing a smooth transition of radial stiffness as the inner layer transitions from a high strength portion to a high electrically resistant portion.
A dielectric fitting assembly comprising;
- an assembly including a hose connected between two end fittings, each end of the hose connected to the fittings by a crimped socket;
- and
- a structural reinforcement portion having at least an inner layer and an outer layer, the inner layer formed of at least different first and second composite materials, the first composite material having a high strength relative to the second composite material and the second composite material having a high electrical resistance relative to the first composite material, the first composite material surrounding the socket of each fitting and extending axially toward the other fitting, the second composite material surrounding the first composite material and surrounding the hose at least between the axially extending portions of the first composite material, the outer layer formed of non-conductive fibres.
A dielectric fitting assembly comprising:
- an assembly including a hose connected between two end fittings, each end of the hose connected to the fittings by a crimped socket;
- and
- a structural reinforcement portion having at least an inner layer and an outer layer, the inner layer formed of carbon fibre reinforced plastic and glass fibre reinforced plastic, the carbon fibre reinforced plastic surrounding the socket of each fitting and extending axially toward the other fitting, the glass fibre reinforced plastic material surrounding the carbon fibre reinforced plastic and surrounding the hose at least between the axially extending portions of the glass fibre reinforced plastic, in which the axially extending portions of the carbon fibre reinforced plastic are positioned bending radially outward from a longitudinal axis of the fitting as the portions extend axially from each socket.
