Abstract
In this experimental and numerical study, an analysis of a failed steel pressure vessel is performed, along with an attempt to repair it using an optimized composite patch. Failure analysis is done using experimental non-destructive testing methods (visual and ultrasonic testing). It occurred that the failure was caused by excessive corrosion around the drain hole of the vessel. In an attempt to repair the vessel using a composite patch, numerical optimization of the thickness of the patch was performed first. A numerically optimized solution was used to build a composite repair patch and apply it to the failed pressure vessel. Experimental analysis revealed that the optimized composite patch is able to withstand the pressure set in the vessel. This type of optimization can help in reducing the costs of applying the composite patch to repair failed pressure vessels.
期刊介绍:
Pressure vessel engineering technology is of importance in many branches of industry. This journal publishes the latest research results and related information on all its associated aspects, with particular emphasis on the structural integrity assessment, maintenance and life extension of pressurised process engineering plants.
The anticipated coverage of the International Journal of Pressure Vessels and Piping ranges from simple mass-produced pressure vessels to large custom-built vessels and tanks. Pressure vessels technology is a developing field, and contributions on the following topics will therefore be welcome:
• Pressure vessel engineering
• Structural integrity assessment
• Design methods
• Codes and standards
• Fabrication and welding
• Materials properties requirements
• Inspection and quality management
• Maintenance and life extension
• Ageing and environmental effects
• Life management
Of particular importance are papers covering aspects of significant practical application which could lead to major improvements in economy, reliability and useful life. While most accepted papers represent the results of original applied research, critical reviews of topical interest by world-leading experts will also appear from time to time.
International Journal of Pressure Vessels and Piping is indispensable reading for engineering professionals involved in the energy, petrochemicals, process plant, transport, aerospace and related industries; for manufacturers of pressure vessels and ancillary equipment; and for academics pursuing research in these areas.
