“…Corrosion is a persistent problem for many modern high-precision applications, such as automotive 1 and aerospace [2][3][4] or speciality gas handling. [5][6][7][8] Components for these applications require many high-purity precision parts and instruments, which are commonly manufactured from steel or aluminium alloys. As such, these parts need to be protected by dense and defect-free coatings to prevent corrosion.…”

“…Because of the extensive use of steel cylinders and the particularity of safety, many scholars have studied the safety performance of steel cylinders. Akhtar et al [1] have developed an acoustic emission test method that can distinguish between general corrosion product signals and mainly crackrelated signals. The sensitivity of this method can guarantee the inspection interval of natural gas cylinders once every five years during the service period.…”

Gas cylinders are widely used in industrial production and daily life. Due to the complexity of the medium contained in the cylinder and the unsafe factors in the use and management, cylinder accidents occur more frequently. This paper analyzes the cause of a burst accident in the liquid ammonia cylinder. The results show that the chemical composition and mechanical properties of cylinder materials basically meet the requirements of relevant standards. No obvious defects were found on the weld and fracture surface during NDT. The outer surface of the gas cylinder is severely corroded, especially in the weld area, where there is a lot of pitting corrosion.

“…In recent research works, a lot of works were goaled to achive the criteria. For the example, AE testing results can be evaluated to grade the cylinder condition [7,8], CNG-1 metal type, was done to evaluate the acceptance of the cylinder, and the other type cylinders were interested to study by AE during felicity effect occurred before cylinder broken [9]. Most research works should study and understand the character of acoustic sources therefore an acoustic signal characteristic and acoustic emission parameters were analyzed for acoustic source identification and noise seperation.…”

The objective of this paper is to study the different acoustic emission (AE) activities from material integrity and leakage which were obtained from CNG steel cylinder during pressurization. CNG type I cylinders were employed to test by hydrostatic stressing. The pressure was continuously increased to over 1.1 time of operating pressure or leakage occurrences. AE sensors, resonance frequency of 150 kHz, were mounted on the outside cylinder wall to detect the AE activities throughout the testing. AE activities were compared between AE of material expansion and leakage by amount of AE signals detected then analyzed by AE parameters. AE parameters including Amplitude, Count, Energy (MARSE), Duration and Rise time were analyzed to distinguish the AE data. The AE wave form in time and frequency domain were also considered in analysis process. The location of AE sources were located by the calculation the arriving differenced time of 2 or more sensors to indicate the position of cylinder faults. The results showed the AE signals of material expansion were randomly detected throughout the pressurization until the Enegy and Amplitude of detected signals were increased by high incresing rate where was leakage occurrences. AE parameters of Amplitude and Energy can be significantly represented the difference between material expansion and leakage. Addition, the Hit rate monitoring cloud be a notice activity before cylinder leaks. The benefits of this work are the AE characterization of the material expansion, leakage and noise for improvement of Type-1 CNG cylinder tests.
