The invention relates to a test system for simulating thermal insulation performance of a pipeline under deepwater environment, the system is capable of respectively simulating deepwater pressure, deep sea seawater temperature by simulating a hydraulic pressure system, a constant temperature water-bath system and an insulating pipeline cycle heating system and capable of conveying a thermal medium to simulate the pipeline conveying of the crude oil, a heat radiation loss test system realizes real-time signal acquisition, so that medium temperature, external surface temperature of heat-insulation layer of a test pipeline sample as well as external surface hot-fluid density of the heat-insulation layer in test pipeline sample for conveying the thermal medium under simulation of deep sea seawater environment temperature and deepwater pressure environment can be recorded, thereby thermal insulation performance of the test pipeline sample under simulation condition can be understood, and change condition of physical property which can be compressive strength and aging resistance performance of a pipeline insulation material is tested under simulation test of long time condition operation.
Description
technical field [0001] The invention relates to the technical field of pipeline thermal insulation performance testing in deep water environments, in particular to a pipeline thermal insulation performance test system for simulating deep water environments, which is used to test thermal insulation structural performance of oil pipelines in deep water pressure and temperature environments. Background technique [0002] As my country's demand for oil and gas is increasing, in order to reduce the gap between oil and gas supply and demand and the dependence on foreign imports, the development of deep-sea oil and gas resources has become an important part of my country's energy strategy and has been vigorously developed. Different from shallow sea oil production, deep sea oil pipelines put forward higher requirements both in terms of performance and installation process. [0003] The deep-sea subsea environment has low temperature and high water pressure, and the temperature of d...
