In the process of shale oil and gas development, TPU layflat hoses are widely used in key areas such as high-pressure fluid transportation, fracturing operation auxiliary pipelines, and equipment connections due to their excellent wear resistance, oil resistance, and flexibility. Scientific selection is an important prerequisite for ensuring the safe operation of the system and improving operational efficiency. Firstly, it is necessary to clarify the operating conditions, including the type of conveying medium (such as fracturing fluid, diesel, water-based or oil-based mud), working pressure range, environmental temperature changes, and the presence of chemical corrosive substances. Polyurethane materials have good resistance to hydrocarbon solvents, but may swell or experience performance degradation under long-term exposure to strong polar solvents or high temperature environments. Therefore, material compatibility should be evaluated based on the actual composition of the medium. Secondly, work pressure is a key parameter that determines the thickness of the hose wall and the structure of the reinforcement layer. Multi layer woven steel wire or aramid fiber is usually used as a reinforcing skeleton to withstand high voltage pulses and instantaneous impacts. When selecting, it should be ensured that the rated working pressure of the hose is not less than 1.5 times the maximum operating pressure of the system, and the fatigue effects caused by pressure fluctuation frequency and duration should be considered. The bending radius is also an important factor that cannot be ignored. When laying pipes in narrow spaces or frequently moving equipment, it is necessary to choose hoses with a smaller minimum bending radius to avoid inner wall wrinkles, delamination, or outer layer cracking caused by excessive bending. In addition, the length of the hose should balance flexibility and pressure drop control. If it is too long, it will increase flow resistance and affect pumping efficiency; If it is too short, it will limit the range of device movement. In terms of connection methods, existing joint standards should be matched to ensure reliable sealing and easy disassembly. Common forms include quick couplings, threaded connections, and flange connections. During installation, attention should be paid to avoiding twisting, stretching, and friction damage. It is recommended to install protective sleeves or guiding devices to extend the service life. Regularly inspect the surface of the hose for scratches, bulges, hardening, or delamination, replace aging components in a timely manner, and prevent sudden leaks from causing safety accidents. Overall, the performance requirements for TPU layflat hoses in the shale oil and gas field are extremely strict. Selection must be based on comprehensive technical evaluation and systematic matching with actual on-site conditions in order to achieve efficient, safe, and sustainable operational goals.
