| Objectives | The project consists: Complete offsite trials and onsite live trails of the reinforcement clamp. Complete SGN/PM/G23 for reinforcement clamp. Removal of stud bolts using reinforcement clamp on live site. Complete a variety of offsite testing to calculate the corroded cross sectional area and the remaining strength of the stud bolts. Development of a screening tool documenting evidence from offsite testing. This will be developed into a user guide based on bolt conditions, operating parameters and all other relevant details. Development of a bolt replacement procedure and training instructions. Submission of a final project report with full details of the work and testing done throughout the project. The aim of this project is to carry out investigation to develop an understanding of how corrosion affects the strength of a stud bolt and to see if it can be approximated by the cross-sectional area of the uncorroded material. In order to determine the replacement extension for bolt within plants and pipelines, a screening tool will identify the high risk bolts to replace. To do this, specimens will be removed from site using the Hydratight Reinforcement Clamp, and will be subjected to various tests. These tests will determine the remaining strength left in a corroded bolt and cross referenced to understand if there is a visible trend. The objectives of this project are to: Complete offsite trials and onsite live trails of the reinforcement clamp. Complete a variety of offsite testing to calculate the corroded cross sectional area and the remaining strength of the stud bolts. To give a quantitative measure for the corrosion as a percentage of metal loss or cross sectional area. Development of a screening tool documenting evidence from offsite testing. This will be developed into a user guide based on bolt conditions, operating parameters and all other relevant details.Understand how the corrosion affects the remnant strength and life in the bolt. Develop a bolt replacement procedure and training instructions. | |
