According to the national standards of oil and gas pipeline fire test in China (GB13347—92), six DN50 crimped ribbon deflagration arrestors belonging to Group ⅡA were tested by experiments, and the flameproof velocity of every single arrestor was obtained. The experimental results show that the expansion ratio, the length of the narrow channel and the cross-section of the narrow passage are the three dominant factors that influence the flameproof velocity. Based on this analysis, the relation between the flameproof velocity and the expansion ratio, the thickness of the crimped ribbon element and the cross-section of the narrow passage were presented. The results indicate that the flameproof velocity is proportional to the length of the narrow channels and the square of expansion ratio, whereas it is inversely proportional to the feature size of the cross-section. This study can provide guidance in the design and manufacture of crimped ribbon deflagration arrestors.
