Description

Technical Field

[0001] The present invention relates to the technical field of pipeline application, and more particularly to a composite material pipeline. Background Art

[0002] Thermoplastic composite pipes (TCP) can be used in renewable applications such as oil production, water injection, gas lift, chemical injection, methanol (including MEG) injection, and hydrogen and carbon dioxide transportation. Due to its corrosion resistance, smooth surface, light weight, coilability and excellent field operability, it is the best solution for field oil flowlines, return oil pipes, single well oil flowlines, (quasi) static risers and offshore wind power array pipelines. Thermoplastic composite pipes (TCP) are known for their simplicity. TCP pipelines can be coiled, with cost-effective horizontal laying and minimum installation costs. In addition, due to its corrosion resistance, it reduces corrosion-related costs, such as pumping corrosion inhibitors and related cleaning. Pipeline and other costs, a special advantage of TCP is that we can terminate the pipeline at sea, another special advantage of TCP pipeline is that the pipeline can be terminated at sea, which provides extremely high flexibility for offshore laying and allows bending into a J-shaped pipe without fittings, which reduces the size and cost required for the J-shaped pipe, which is especially beneficial in brownfield applications where there is not much space on offshore platforms. The hard pipe wall is composed of a liner, a thermoplastic composite reinforcement layer and an outer coating, and is fused together to ensure that the bond between the layers is as strong and durable as the substrate. TCP is a high-performance, spoolable pipe that is corrosion-resistant, reduces the total installation cost, and has a smaller overall carbon footprint than steel.

[0012] Technical effects and advantages of the present invention: 1. After the first composite material pipe and the second composite material pipe are assembled, the user injects the liquid for sealing through the injection tube on the top of the injection ring, so that the liquid flows into the first composite material pipe and the second composite material pipe through the injection ring and the drainage ring, so that the cavity between the first composite material pipe and the second composite material pipe is filled with liquid, ensuring the sealing of the connection between the first composite material pipe and the second composite material pipe.

When the first composite material pipe is turned over as a whole and the connection matching ring is facing downward as a whole, the liquid between the first composite material pipe and the second composite material pipe flows in the cavity, driving the sealing ball to roll to the inside of the guide ring. Under the influence of the pressure of the liquid flow, the sealing ball drives the guide ring to be clamped inside the positioning ring, so that the sealing ball is blocked in the positioning ring as a whole, so that the cavity is sealed again.

When the second composite material pipe rotates on the outer wall of the first composite material pipe, the spring baffle inside the external thread presses the internal thread, so that after the external thread and the internal thread are threadedly connected, the internal thread is pressed between the external thread and the internal thread to prevent the external thread and the internal thread from loosening. A sealing ring is arranged on the outer wall of the guide ring. When the second composite material pipe and the first composite material pipe are assembled, the spring pressing ring inside the sealing ring presses the sealing ring as a whole, so that after the second composite material pipe and the first composite material pipe are assembled, the sealing ring as a whole fits the inner wall of the second composite material pipe, so that the space where the first composite material pipe and the second composite material pipe are connected is sealed.

The first composite material pipeline 1 and the second composite material pipeline 11 are connected to each other so that the cavity between the first composite material pipeline 1 and the second composite material pipeline 11 is filled with liquid to ensure the sealing of the connection between the first composite material pipeline 1 and the second composite material pipeline 11. When the first composite material pipeline 1 is turned over as a whole and the connection matching ring 15 is facing downward as a whole, the liquid between the first composite material pipeline 1 and the second composite material pipeline 11 flows in the cavity, driving the sealing ball 22 to roll to the inside of the guide ring 19. Under the influence of the pressure of the liquid flow, the sealing ball 22 drives the guide ring 19 to be clamped in the inside of the positioning ring 18, so that the sealing ball 22 is blocked in the positioning ring 18 as a whole, so that the cavity is sealed again. At the same time, under the influence of the liquid pressure, the sealing ball 22 of the turned over first composite material pipeline 1 is always clamped with the positioning ring 18 to seal the cavity connected between the first composite material pipeline 1 and the second composite material pipeline 11, so as to prevent the gas or liquid flowing inside the first composite material pipeline 1 and the second composite material pipeline 11 from leaking, which affects the normal use of the first composite material pipeline 1 and the second composite material pipeline 11.

[0023] Working principle: When the pipeline is in use, the first sealing connection ring 2 is placed on one side of the first composite material pipeline 1, and the first sealing connection ring 2 is connected to the first composite material pipeline 1 through the first connecting groove 3 inside the first sealing connection ring 2, and the connection matching ring 15 is integrally sleeved on one side of the limiting ring 14 on the outer wall of the first composite material pipeline 1, and the second composite material pipeline 11 is integrally inserted into one end of the first composite material pipeline 1. During the insertion of the second composite material pipeline 11, the adjustment block 26 on the inner wall of the second composite material pipeline 11 presses against one end of the first composite material pipeline 1, so that the first composite material pipeline 1 as a whole adjusts the insertion angle of the second composite material pipeline 11, and the second composite material pipeline 11 as a whole is rotated so that the internal thread 28 on the inner wall of the second composite material pipeline 11 is threadedly connected with the external thread 27 on the outer wall of the first composite material pipeline 1. When the second composite material pipeline 11 rotates a certain angle, the limiting ring 14 on the outer wall of the second composite material pipeline 11 is clamped on one side of the connection matching ring 15, so that the second composite material pipeline 11 as a whole is rotationally limited on the outer wall of the first composite material pipeline 1; At the same time, when the second composite pipe 11 rotates on the outer wall of the first composite pipe 1, the spring stopper 29 inside the external thread 27 presses against the internal thread 28, so that after the external thread 27 and the internal thread 28 are threadedly connected, the internal thread 28 presses between the external thread 27 and the internal thread 28 to prevent the external thread 27 and the internal thread 28 from loosening. A sealing rubber ring 8 is provided on the outer wall of the guide ring 5. When the second composite pipe 11 and the first composite pipe 1 are assembled, the spring pressing ring 9 inside the sealing rubber ring 8 presses against the sealing rubber ring 8 as a whole, so that after the second composite pipe 11 and the first composite pipe 1 are assembled, the sealing rubber ring 8 is integrally attached to the inner wall of the second composite pipe 11, so that the space where the first composite pipe 1 and the second composite pipe 11 are connected is sealed, so as to prevent the first composite pipe 1 from being connected to the second composite pipe 11. The gap causes the use of the first composite pipe 1 as a whole. Secondly, after the first composite material pipe 1 and the second composite material pipe 11 are assembled, the user injects the liquid for sealing through the injection tube 23 at the top of the injection ring 17, so that the liquid flows into the first composite material pipe 1 and the second composite material pipe 11 through the injection ring 17 and the drainage ring 20, so that the cavity between the first composite material pipe 1 and the second composite material pipe 11 is filled with liquid, ensuring the sealing of the connection between the first composite material pipe 1 and the second composite material pipe 11. Secondly, after the external thread 27 and the internal thread 28 are sealed, the internal thread 28 is pressed between the external thread 27 and the internal thread 28, so that the connection between the first composite material pipe 1 and the second composite material pipe 11 is sealed, thereby increasing the overall sealing of the first composite material pipe 1 and the second composite material pipe 11. In addition, when the first composite material pipe 1 is flipped as a whole and the connecting matching ring 15 is facing downward as a whole, the liquid between the first composite material pipe 1 and the second composite material pipe 11 flows in the cavity, driving the sealing ball 22 to roll to the inside of the guide ring 19. Through the influence of the pressure of the liquid flow, the sealing ball 22 drives the guide ring 19 to be clamped inside the positioning ring 18, so that the sealing ball 22 is blocked in the positioning ring 18 as a whole, so that the cavity is sealed again. At the same time, through the influence of the liquid pressure, the sealing ball 22 of the flipped first composite material pipe 1 is always clamped with the positioning ring 18 to seal the cavity connected between the first composite material pipe 1 and the second composite material pipe 11, so as to prevent the gas or liquid flowing inside the first composite material pipe 1 and the second composite material pipe 11 from leaking, affecting the normal use of the first composite material pipe 1 and the second composite material pipe 11.
