Question regarding inspection of vessels/tanks,..
(OP)
Hi everybody,
For API 597 ( Fitness For Service), and I believe also in API 510, 653 There are two options for making thickness measurements.
Option 1 : thickness readings with a digital device.
Option 2: thickness profile.
My question , is since I am not an inspector is:
With which device can you make these profiles measurements ??
Please send adresses and sites of possible suppliers and makers of these devices.
Thanks
Fathi

To my understanding ( unless I am mistaking ) these Krautkramer gauges and other similiar gauges are for
THICKNESS READINGS (Thus one reading at a time).
My Question is and was: Which devices are used for making
Thickness PROFILES ???
is there a software which has to be added ??
RE: Question regarding inspection of vessels/tanks,..
Thickness readings are used to evaluate whether thickness is uniform, indicating general corrosion. If there are large differences in the thickness readings, the thin area is located, and a thickness profile is used to characterize the remaining thickness and size of the region of metal loss.

I assume the software you are talking about can
calculate the "tm" and "tam" (average and minimum) as defined n section 4 of API579 .

Your best course of action would be to contact a local sales engineer for Krautkramer (or other) equipment. He (or she) would be happy to give you a demonstration.

i have used both Panametric and KK; prefer the KK DataMate, to do headers up to 4" thick, tubes as thin as .120", and tanks (coated & uncoated) slightly less than both.
condition (internal & external) of the tanks you are looking to inspect also play a large part in knowing which type of device to use (single or dual trace) and size of transducer.
again, refer to my first sentence. after that do a google search for nde inspection companies, there are a bunch out there.
i have managed inspection projects that used various companies with satisfactory results. TEC, FiveStar, MQS to name a few.
