ABSTRACT:
A high tensile strength and high abrasion resistant removable hose covering and method of construction is described for fabricating a reusable, removable hose covering adapted to surround an inner hose by which high tensile strength in the longitudinal direction may be imparted to the combination of the inner hose and removable hose covering and in addition, extreme high resistance to environmental abrasion is obtained. The inner hose is constructed by conventional methods. The removable hose covering is constructed by firstly locating a hooking type separable closure mechanism on opposite sides, placing under tension parallel high tensile strength longitudinal cables between the closure mechanisms, encompassing the longitudinal cables with elastomeric hose materials, placing under tension transverse hose reinforcement materials between the separated closure mechanisms, adding additional layers of elastomeric materials as needed covering the transverse hose reinforcement, adding a hose covering material, and finally vulcanizing the elastomeric materials of the removable hose covering. The removable hose covering is placed around the inner hose, the closure mechanism engaged, and the combination held between two distant points. The longitudinal cables provide both the high tensile strength and the extreme resistance to environmental abrasion and damage.
