Their objective is to ensure an acceptable level of quality, and implicitly, operational safety. They seek to achieve this by imposing workmanship standards which prescribe the allowable size and frequency of various discontinuities. These standards are largely arbitrary and thus highly conservative in most situations. However, the potential for economic benefit, an increasing demand for safety, and the development of fracture mechanics technology have motivated the inclusion of optional fitness-for-service (FFS)-based flaw acceptance criteria. Two major objectives of the present work were to educate those unfamiliar with structural reliability concepts, particularly as they apply to pipeline integrity, and review the worldwide codification of LRFD for industries that fabricate and maintain welded structures. The final objective was to develop a library of PSFs for pipeline girth weld flaw assessment thereby aligning girth weld fitness-for-service assessment procedures with emerging LRFD codes for transmission pipelines.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44367556214862,"sku":"15728","price":195.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/l51779-reliability-based-fitness-for-service-assessment-of-welds-1","provider":"PRCI Store","version":"1.0","type":"link"}
