“…T standard outlines the design requirements and test criteria that LNG hoses must ful The cryogenic hoses used for LNG are divided into two main types based on the structu form: one is metal corrugated hoses and another with the wall made of polymer films a polymer braided materials wound into a multilayer wall structure called cryogenic co posite hoses [7]. The metal corrugated hoses are further categorized into reinforced m corrugated hoses and high vacuum metal corrugated hoses, specifically [20].…”

Recently, the application of cryogenic hoses in the field of cryogenic media has become a hot topic, especially in the industry of offshore liquefied natural gas and aerospace field. However, the structure of cryogenic hoses is complex, and reasonable structural properties are required due to the harsh working conditions. There is still plenty of scope for further development to improve the performance in all aspects. In this paper, the current development status of cryogenic hoses for liquefied natural gas (LNG) transportation is reviewed first, including the types, manufacturers, structural forms, performance, and key technical challenges. And then, the recent progress and prospect of cryogenic hoses for cryogenic liquid transportation (such as LNG and liquid oxygen) are summarized, including structure design, low-temperature resistant polymers, liquid oxygen compatible polymers, and leakage monitoring technologies. This paper provides a comprehensive overview of the research development and application of cryogenic hoses. Moreover, future research directions have been proposed to facilitate its practical applications in aerospace.

“…For flexible pipe, the reinforced armor layer is adopted for bearing the tension and inner pressure loads, and the winding angle is usually between 30 • and 40 • [19,20]. For cryogenic flexible hose, the reinforced armor layer mainly aims to bear the inner pressure and outer impacting loads, and the winding angle is usually between 75 • and 80 • [21]. The tensile strength of helically wound structures with a small angle is high, while the structure with an angle has a strong radial resistance capacity and is more flexible.…”

Marine flexible pipe/cables, such as umbilicals, flexible pipes and cryogenic hoses, are widely adopted in ocean engineering. The reinforcing armor layer in these pipe/cables is the main component for bearing loads, which is a typical multi-layer helically wound slender structure with different winding angles for different devices. There has been no general theoretical methodology to describe the tensile performance of these flexible pipe/cables. This paper first introduces a theory to solve the tensile mechanical behavior of a helically wound structure. Based on the curved beam theory, a solution of the tensile stress of a helically wound slender is derived. Then, the deformation mechanism of the marine flexible pipe/cables structure with different winding angles is studied. Through comparing theoretical and numerical results, the deformation characteristic of the helically wound slender structure is further explained. It is found that a sectional torsional deformation generates when the structure with a larger winding angle is under tension condition, while the sectional deformation of the structure with a smaller winding angle is mainly tension. Finally, a couple types of marine flexible pipe/cables under the tension condition are provided to analyze the mechanical performance and compare the difference between different theoretical models. The research conclusion from this paper provides a useful reference for the structural analysis and design of marine flexible pipe/cables.

“…Regier et al [20] conducted experimental research on deteriorated corrugated steel pipes, and the results showed that the corrosion level affects the bearing capacity of corrugated steel culverts. Yang et al [21] used parametric numerical simulations to simulate the mechanical behaviour of helical corrugated steel pipes under axial tension, bending, and internal pressure loads and combined the simulations with a multiobjective optimization algorithm to propose an optimization method for the structural design of liquefied natural gas cryogenic helical corrugated pipes. Guo et al [22] analysed the characteristic buckling of the concrete-infilled double steel corrugatedplate wall and studied its overall elastic buckling behaviour under axial load.…”

To ensure the safety of ships and bridges at the same time during collisions, a new type of bridge pier protection system is proposed, in which one is composed of corrugated steel plates, bolts, and corrugated steel pipes (CSP), and the other is composed of ordinary steel plates, bolts, and corrugated steel pipes (OSP). To study their anticollision performance, a pendulum impact test and numerical simulation were carried out. Comparing the test results with the simulation results, it was shown that the simulation results are basically consistent with the test results. Then, the influence curves of the impact velocity, specimen thickness, weight, and frequency are analysed to evaluate the anticollision performance of CSP/OSP and optimize their structure. When the impact energy is low, the peak values of the lateral impact force and lateral displacement of the column equipped with OSP are all smaller than those of the column equipped with CSP. When the impact energy is high, the peak values of the lateral impact force and lateral displacement of the column equipped with OSP are larger than those of the column equipped with CSP. However, under the same impact energy, the total energy peak value of the CSP specimen is larger than that of the OSP specimen. Results can provide a certain numerical analysis basis for the structural design and research of new types of corrugated steel protection system for bridge pier.
