In the late 1960s and early 1970s, a study was completed in which a series of burst tests was conducted on 41 pipes ranging from 8 to 42 inches in diameter and representing API Specification 5L Grades A through X65. In this study, only 2 of the 41 materials studied had a yield-to-tensile ratio greater than 0.9, and these were artificially created. With the advent of the X70 and X80 steels, higher yield-to-tensile ratios have developed as the yield strength increased. A re-examination of this question in terms of the higher strength materials is presented herein. The objective of this research is to determine if the high yield-to-tensile ratio of X70 and X80 line-pipe steels in any way restricts such operating practices as hydrostatic testing, operating stress level, and flaw behavior.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44362021273678,"sku":"14960","price":349.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/l51562-a-study-of-the-yield-tensile-ratio-and-its-effect-on-line-pipe-behavior","provider":"PRCI Store","version":"1.0","type":"link"}
