There is data in the new book, Guidelines for Initiating Events and Independent Protection Layers, 2015, CCPS/AIChE. (It is finally published as of January 8, 2015.) The failure rate is presented in probability of failure (due to damage mechanism such as corrosion) per meter of pipe. Two different values (for different diameter ranges) are presented for piping in non-materials sensitive service and two for material-sensitive service. In material sensitive service (for instance, where alloys are used), the use or lack thereof of positive material identification (PMI) plays a pivotal role in the failure rate (without 100% PMI of as-welded, the result could be 10 to 100 times the failure rate with 100% PMI).
