PA effectiveness in corrosion and thickness survey

We paln to buy a PA equipment with 16:64 or 16:128 configurations for using in a production (GAS) platform offshore for corrosion analysis of equipments as well as thickness readings in piping. Can some one advise the PA system's effectiveness or is it worth to buy a PA system for this purpose?

As always, whether you use PA or conventional UT depends on your specific application. PA will give you a B-scan-type image which may help, and will also give you a high pulse density, which may be useful if you are looking for pinhole-style corrosion. If you want to automate the scanning, you will need a PA unit that is encoded. On the other hand, PA is more expensive and more demanding to set-up.

My recommendation would be to check the relevant PA manufacturers' web sites for equipment, and also manufacturers for corrosion meters etc. Then ask the sales reps to visit you.
