Safety Update: High Pressure Cylinder Inspection and Testing

DNV GL has added acoustic emissions testing (AE) to its rule set, making it the preferred method for seamless steel gas cylinders’ periodic inspection and testing – is this the end of periodic hydro testing?
The hydro test can cause concerns over safety, the long time it takes and the expense.
AE testing is claimed to be faster, cheaper and safer.
This paper examines the benefits of AE over hydro testing within the regime of periodic inspections and tests.
