Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0015] Examples are attached figure 1 shown. The performance test device for the sealing system of marine flexible riser joints includes end glands, sleeves 5, pipe protection sleeves 6, large bolts 13 and the joints to be tested. The joints to be tested include small bolts 7, wedge seal rings 8, seal load Flange 9, support sleeve 11 and inner sheath 12 of the pipe cable. The end gland is a round cover with a groove in the middle, which is divided into front end gland 4-1 and rear end gland 4-2. The groove part of the cover 4-1 has a temperature sensor interface 1, a pressure pump interface 2 and a heater interface 3, and the pressure pump interface 2 is connected with the pressure pump. The used medium of the pressure pump is water, and the heater interface ( 3) A heater is connected, and the pressurized pump interface 2 and the heater interface 3 ...

A performance testing device of a marine flexible vertical pipe connector sealing system comprises end glands, a sleeve, a pipeline protecting sleeve, large bolts and a tested connector, wherein the end glands are round covers provided with grooves in the middles and provided with temperature sensor interfaces, booster pump interfaces, heater interfaces and pressure gauge interfaces, the peripheral positions of the end glands are evenly provided with bolt holes, and the large bolts enable the front and rear end glands to be connected. The sleeve is arranged between the front and rear end glands. The pipeline protecting sleeve is a cylinder matched with the tested connector and arranged in the sleeve. Two sealing load flanges of the tested connector are respectively and fixedly connected at two ends of the pipeline protecting sleeve through small bolts. The performance testing device has the advantages that various working conditions can be simulated, internal structure match of sealing parts can be simulated for testing; members are easy to machine, sealing is reliable, and the performance testing device has the safety, economical efficiency, practicability and universality; sealing performance testing of the sealing parts in a marine flexible vertical pipe connector at a design stage is achieved.
Description
technical field [0001] The invention relates to the technical field of testing, in particular to a sealing system performance testing device for a sealing ring, which is suitable for testing the sealing system inside a marine flexible riser joint. Background technique [0002] With the development of the world economy, the current amount of oil extraction on land is far from meeting the needs of human beings, so more and more countries are turning their attention to the ocean, which contains rich oil and gas resources. As the most commonly used equipment in offshore oil and gas transportation, the flexible riser needs to have a very well-tight connection joint in order to realize the connection with the terminal system. [0003] Before the joint is applied to the actual project, its sealing system must be evaluated. The easiest and most reliable way to check the sealing performance is the sealing test. Considering the high cost of the whole assembly test, it is more suitabl...
