... Abstract Large storage tanks are commonly used to store liquefied petroleum gas, liquefied natural gas, etc. In actual service process, the storage tank is not only vulnerable to foundation settlement, but also prone to structural damage caused by accidental loads such as earthquakes...

.... Keywords: Ultrasonic phased array; Imaging technique; Storage tank; Double curved surface; Welding seam. 1. INTRODUCTION In recent years, most industries have already adopted the ultrasonic phased array imaging techniques for non-destructive testing [1,2]. Phased arrays enable separate firings of multiple...

... Abstract Ultrasonic testing is one of the most common non-destructive testing (NDT) methods for periodic inspection of crude oil storage tanks. Ultrasonic phased array system can effectively and efficiently image different types of defects in the structures through direct contact method...

... Abstract Wind actions are important to consider when performing fitness for service assessment on storage tanks with damage. Tank design codes typically have rules where a design wind velocity is used to determine required dimensions and spacing of wind girders, and a uniform wind pressure...

... Abstract In recent years, with the rapid development of solar thermal power technology in China, the key equipment molten salt storage tank is widely used. Instability is the primary failure mode for these large thin-walled structures. Thus, stability design for the molten salt storage tanks...

... between the resonant response and the input velocity pulse. This paper aims to describe the test plan in detail, and it consists of (1) design of the scaled storage tank and water depth, (2) selection and processing of the input motions including the original near-fault ground motions, extracted velocity...

... Acoustic emission technology is mostly used in corrosion detection of the atmospheric vertical storage tank bottom, but the evaluation results are always affected by the complex sound sources. In this paper, wavelet neural network is used to identify the acoustic emission signals from different...

... for a present target of e.g. 75kWel fuel cell cars aiming at a 400km driving distance with 4 kg of hydrogen. This necessitates a gravimetric storage density of over 6 wt. per cent. The present paper will address the hydrogen storage tank system for on-board applications including storage tank materials, system...
