Consequently, they often contain discontinuities that exceed today's workmanship standards. Operators of pipeline facilities are now being required, by recent legislation and regulation, to provide a higher level of assurance of the integrity of their pipeline systems. Older pipelines present some unique challenges in meeting these requirements.\u003c\/p\u003e\n\n\u003cp\u003eThe objective of this project was to develop a technical basis for demonstrating the integrity of older pipelines at reasonable cost. This work addresses the characteristics of girth welds in older pipelines that prevent assessment of their fitness for service using standard available procedures. The present work focuses on developing a closed-form stress-intensity solution that includes the effects of weld cap size. In addition, this work improves test methodologies for measurement of appropriate material properties in low-strength girth welds.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44367621554254,"sku":"15305","price":495.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/l51936-factors-influencing-girth-weld-reliability-in-older-pipelines-1","provider":"PRCI Store","version":"1.0","type":"link"}
