Abstract
A flexible hose comprising a composite polymeric core with a degradation-resistant liner and a thermoplastic elastomeric liner coating, the core preferably being surrounded by a protective sheath. The degradation-resistant liner is optionally a polyolefin or fluorine-containing polyolefin and can have a convoluted inside surface. The composite core can optionally include a vapor barrier and leak indicator, and a tracer can be provided to indicate twisting of the sheath.
Claims26
A flexible connector hose comprising a composite tubular core consisting essentially of an extruded tubular liner made of linear low density polyethylene surrounded by a coextruded, contacting tubular liner coating made of a thermoplastic elastomer.
A connector hose assembly comprising a tubular core consisting essentially of a polyolefinic liner made of a material selected from the group consisting of low density polyethylene, linear low density polyethylene, high density polyethylene, copolymer polypropylene, homopolymer polypropylene, and mixtures thereof, a braided protective sheath surrounding the core;
- further comprising an extruded tubular liner coating made of a thermoplastic elastomer, the liner coating being disposed between the polyolefinic liner and the protective sheath, and at least one end fitting connected to the protective sheath.
