The objective of the PRCI MATR-3-11 Composite Repair Load Transfer Study was to evaluate the effect of internal pipe pressure during installation of composite reinforcement systems. Historically, there has been little work evaluating the effect of…
In March 2020, the Executive Assembly of PRCI approved Crack Management (CM) as a Strategic Research Priority (SRP). To help refine the scope of PRCI's crack-related research over the next few years, the MAT-8-3 project team of the Design, Materials,…
FAST Pipe is a new pipeline technology that was developed by ConocoPhillips Company (ConocoPhillips). It has been proposed as an alternative to high strength steel (grade X80 or higher) for high pressure gas transmission pipelines. FAST Pipe is…
The American Petroleum Institute (API) initiated this project through Pipeline Research Council International, Inc. (PRCI), to apprise industry consensus recommended practices regarding reasonable and prudent crack in-line inspection (ILI) response…
Evaluates the use of non-destructive surface testing (micro indentation, micro-machining, in situ chemistry, and replicate microscopy analysis) as a means to perform pipe material confirmation.
The results of this research showed that when the material is at a temperature below its fracture propagation transition temperature, the through-wall axial flaw length dynamically created by means of an explosive linear cutter was 75 to 88 percent…
The Cast Iron Fitness-For-Service model described in the main body of this report forms an ideal basis for a simulation tool that can display aggregate system performance in a geospatial database. This simulation tool can provide the operator…
This study was undertaken to determine whether it is feasible to substitute spectrographic analysis for wet analysis in performing check chemical analyses of pipe steels. The use of spectrographic techniques for check analyses has been proposed to…
The Charpy test':' provides a quick, inexpensive, and well-established measure of the fracture resistance of steels. There exists a mass of data on the relations between Charpy energy and metallurgical variables, but it is scattered. Furthermore, a…
This research program was conducted using experimental line pipe in full pipe sections to explore two objectives. The first objective was to determine whether the critical flaw size--toughness relationship developed in the A.G.A. NG-18 Research…
