Stress Analysis on New Multilayer Cylinder With Use of Thin Inner Shell and Cross-Helical Wound Shaped-Steel Ribbon for Pressure Vessels

In this paper, a stress analysis on a new type of multilayer cylinder using thin shell and cross-helically interlocked shaped-steel ribbon wound layers is carried out under the action of internal pressure based on the elastic and elastic-plastic mechanics.

Stationary Flat Steel Ribbon Wound Vessels for Storage of High Pressure Hydrogen

High pressure gaseous hydrogen (HPGH2) storage offers the simplest solution in terms of infrastructure requirements and has become the most popular and highly developed method. HPGH2 storage vessel is the key equipment for HPGH2 storage system. China issued the first national standard on HPGH2 storage vessel named “stationary flat steel ribbon wound vessels for storage of high pressure hydrogen” in 2011. Some crucial technical points are involved in this standard, such as material selection, design method for the shell’s thickness, mehod for determining the winding parameters and detection techniques for the attaching quality between the flat steel ribbon layers. In this paper, a brief introduction is given to the aforementioned technical points.

Construction of Pressure Vessel Using Thin Inner Shell Wound Cross-Helically by Interlocking Strips

This paper describes the construction of a new type pressure vessel using thin shell cross-helically wound interlocking steel strip, based on the technologies of interlocking strip-wound developed by Germany and flat steel ribbon wound by China which are code cases listed in ASME BPVC. Analysis and comparison between the new and the traditional structure types, and discussion on issues such as their stress characteristics, operation safety and manufacturing methods etc. are presented. It shows this new method of pressure vessel construction is feasible, cost effective, and well deserved of further studies.

Heat-transfer analysis of flat steel ribbon-wound cryogenic high-pressure vessel

In the past 40 years, more than 7000 layered vessels using flat ribbon-wound cylindrical shells have been manufactured in China. Theoretical as well as experimental investigations show that there are distinct economical and engineering advantages in using such vessels. In this paper, based on the analysis of the heat transfer process in a flat steel ribbon-wound liquid hydrogen high-pressure vessel, a heat transfer model of the walls of the shell and head has been set up. The temperature difference among the interfaces, the heat transfer through the shell and head, and the evaporation rate of the vessel under a steady heat-flow condition has been calculated. The numerical calculations show that such a structure meets the design requirements.

Optimal Winding Conditions of Flat Steel Ribbon Wound Pressure Vessels With Controllable Stresses

Stress analysis of flat steel ribbon wound pressure vessels (FSRWPVs) is very difficult because they have a special discrete structure and complex pretensions exit in the flat steel ribbons, which are wound around the inner shell layer by layer. An analytical multilayered model for stress analysis is presented in this paper, which involves the effect of prestress in every flat steel ribbon layer as well as in the inner shell. Based on this model, an optimal design method for FSRWPV is suggested, which can assure a reasonable stress level and distribution along the wall thickness during the operation. A practical example of a large FSRWPV is finally given for illustration.
