Re: AE for AST Leak Testing
Dear Mr Wegscheid,

I suggest to contact
Mr Tscheliesnig (tsc@tuev.or.at) and/or
Mr Balmer (MTIIreland@aol.com).
They should be able to provide the information you are looking for.

Re: AE for AST Leak Testing
We have extensive experience particularly with large diameter crude oil storage tanks with FRP/GRP liners typically up to 4 mm thickness.

You need to be sure that personnel testing these tanks have experience in the direct application as liners do affect threshold signals and data analysis. We have prove up data of providers.

Also you should be cautious - leaks in a GRP lined tank are not a common problem as the liner often serves as a leak containment barrier even if substantial metal thickness below the liner has corroded away.

Be cautious also with leaks in crude oil tanks. AE signal origin has to be considered as does time of monitoring. Sludge often temporarily blocks holes making leak signal appear and disappear.

For more data contact me direct.

SITEX CPSERIES

Teledyne ICM’s CPSERIES has been designed with a view to revolutionizing the handling and perfor
...
mances of portable X-Ray sets. Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI).
