Bending limiter with heat dissipation function

Abstract

The invention relates to a bending limiter with a heat dissipation function. The bending limiter is used for protecting a flexible vertical pipe and comprises a heat dissipation module unit and a connecting module unit, wherein the heat dissipation module unit comprises two semi-arc-shaped inner modules, and the inner diameter of each inner module is matched with the pipe diameter of the flexible vertical pipe; each inner module comprises a main inner module body located in the middle portion and end bosses arranged at the two ends respectively; heat dissipation holes are formed in the main inner module bodies; the two inner modules wrap the outer surface of the flexible vertical pipe to form a heat dissipation module unit; the connecting module unit comprise two semicircular outer modules which are connected with each other, and the flexible vertical pipe and the inner modules can be wrapped by the two outer modules after the two ends of the two outer modules are connected with each other; and each outer module comprises a middle part, two side parts and two ends, the inner diameter of the middle part is matched with the pipe diameter of the flexible vertical pipe, two side grooves are symmetrically distributed in the two side parts along the inner wall of the middle part, and the size of the side grooves is matched with the size of the bosses at the end parts of the inner modules.

Description

technical field [0001] The invention relates to a split-type bending limiter with heat dissipation function, which belongs to the field of submarine cable protection in offshore platforms. Background technique [0002] As the exploitation of offshore resources tends to be scarce, the exploitation of oil and gas resources has gradually entered the deep sea in recent years. It is imminent to improve the independent design and construction technology of deep-sea oil and gas development equipment and the design ability of large-scale offshore engineering equipment. The deep-sea flexible riser is a bridge between the offshore platform and the subsea oil field, and is a key part of the deep-sea oil and gas production system. Compared with the traditional rigid riser, the flexible riser has lower rigidity, stronger plasticity, and is more adaptable to the harsh deep-sea environment, so it is widely used in deep-sea oil and gas exploitation. Its bending ability is strong, and it is...

Problems solved by technology

The flexible riser is usually composed of multiple layers of different materials, and the maximum working temperature that different materials can withstand is different. The flexible riser is easy to exceed the maximum working temperature that a certain layer of material can withstand under the condition of high temperature continuous operation, resulting in the riser The structure of this layer fails, which affects the service life of the flexible riser
