Sh. Dai, METHODOLOGY FOR PREDICTING THE OCCURRENCE OF FAILURE EVENTS FOR PRESSURE-VESSELS USED IN THE PROCESS INDUSTRY, International journal of pressure vessels and piping, 75(3), 1998, pp. 221-228
The prediction of the occurrence of failure events for pressure vessel
s used in the process industry is a newly developing technology in the
field of modem technical management of facilities. It is of great sig
nificance for ensuring safe and high efficiency operations in moderniz
ed large-scale and high parameter facilities of chemical, petrochemica
l, nuclear and electric power plants. Approximate and plausible reason
ings have been proposed in the present methodology as the main procedu
re for drawing conclusions from hypotheses or facts involving uncertai
n parameters of fuzziness. In this study, a series of new techniques f
or predicting failure probability, gravity of perniciousness of failur
e events, damage to structural materials and remaining life, etc., hav
e been developed. These techniques have met with success and have obta
ined economic benefits. A brief statement of theoretical work and actu
al case studies is given. (C) 1998 Elsevier Science Ltd. All rights re
