Title:
SHALE GAS FRACTURING FLOWBACK DELIVERY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/056848
Kind Code:
A1
Abstract:
A shale gas flowback delivery device, said device (100) comprising hoses (110, 115) and joints (120, 125), the joints (120, 125) being used for connecting the hoses (110, 115); each of the hoses (110, 115) comprises an outer layer (330) of the hose, a middle layer (320), and an inner layer (310) of the hose, the inner layer (310) of the hose being made of a thermoplastic polyurethane material, the middle layer (320) being made of a reinforced fiber material, and the outer layer (330) of the hose being made of a polymer; and the surface of each of the joints (120, 125) is provided with an anticorrosion coating, and the material of the anticorrosion coating contains 6 wt% to 10 wt% of a nano-organotitanium polymer. According to said delivery device, the thermoplastic polyurethane material having corrosion resistance is used as the material of the inner layer of the hose, and the anti-corrosion coating is provided on the surface of the joints, so that a delivery system is not easily corroded when shale gas fracturing flowback having complicated chemical compositions is delivered therein, prolonging the service life of the delivery system.
