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…
The objective of the research presented in this report was to investigate the performance of patch-type composite repairs on pressure vessels with through-wall defects. The most common repair geometry for bonded composites is the full-encirclement…
A testing program was conducted to evaluate the effects of internal pressure during the installation of composite and steel sleeves repair systems on pipelines with plain dents. The testing program included cyclic pressure testing a group of…
In this study, two severe dent and gouge defects were repaired and submitted to both fatigue and burst pressure in order to investigate on the consistency of using composite sleeves on mechanical damage. The two defects were created on a X63 OD 24''…
Composite materials installed on pipelines where damage generated by corrosion or erosion that begins as a wall-loss defect that can transition to a through-wall defect. Critically, the damage generated by the process tends to have a region of…
PHMSA guideline for using composite repair materials in both onshore and offshore pipeline applications. Based on knowledge and full-scale testing. Includes instruction for properly using composite materials based on the pipeline defects, design a…
Composite reinforcement systems have seen extensive use in the pipeline industry over the last two decades as solutions to address a range of pipeline integrity threats. Despite their widespread use, few options exist for reliable inspection of…
In the current extension of the work, three additional inspection trials were successfully completed by two NDE vendors, Sonomatic Ltd and Testex, Inc. The Sonomatic inspection team used two advanced ultrasonic techniques, M-skip and Dynamic Response…
This document, Guidelines for Using Composite Systems to Repair High Pressure Gas and Liquid Transmission Pipelines, was prepared for the Pipeline Research Council International, Inc. to provide direction for operators of high pressure transmission…
The objective of this project is to evaluate reinforcing technologies, specifically, the use of composite materials for the MAOP determination of high-pressure gas or liquid transmission pipeline systems. Reinforcing a pipeline using composite…
