Ultrasonic testing and Monitoring of Hydrogen blistering and Hydrogen-induced Cracking of LPG Storage Tanks

Abstract

Due to the presence of various corrosive chemicals in LPG (liquefied petroleum gas, or propane) storage tanks, it is very likely to cause different degrees of corrosion in the tank and derive various defects. This article analyzes the main characteristics and types of defects found in storage tanks and provides an overview of ultrasonic testing and monitoring of defects such as hydrogen blistering and hydrogen-induced cracking.
