摘要： A fracturing liquid delivery hose for recovery of shale oil and gas, and manufacturing method and co-extrusion mold thereof are provided. The method includes extrusion of a cover layer with a first adhesive layer and an inner lining layer with a second adhesive layer, formation of an enhancement layer, heating and pressurizing for bonding between the cover layer and the enhancement layer and between the inner lining layer and the enhancement layer, so that the formed fracturing liquid delivery hose has resistance at least to high pressure and chemical corrosion. The cover layer and the inner lining layer can use different types of materials.

摘要： A non-penetrating multi-layer continuous hose and a preparation method thereof are provided. The hose includes an outer coating, a reinforcement layer, and an inner coating. The inner coating and the outer coating can have one or more layers with different materials and have an adjustable thickness. The hose is prepared by simultaneously performing extrusion coating inside and outside the reinforcement layer rather than penetrating the fiber reinforcement layer. The hose exhibits improved layer-to-layer adhesion and has high strength, and continuous production can be achieved to meet the length requirement in various kinds of construction, which has high applicability.
