As Sjones said, it depends upon what spec you are trying to meet. If it is ASME, Section V is the rule. If not, order ASTM Volume 03.03 containing all of the standards applicable to NDT and PT. There are about eight of them for PT.

In the nuclear industry, procedures for stainless steel piping go down to about 0.237" and we don't count any bounces. If we don't have two sided access we get no credit for anything on the other side of the weld because we can't be sure the wave is even getting through the weld. Typically all...
My purpose is to find typical drawings that can be used in ultrasonic thickness testing reports (I suppose hull outlines and sections since that is where much of the testing is done) and in training programs to train personnel on ship construction.

Does anyone know of any CAD programs that come with typical/sample ship drawings already in them?

The UT sound wave enters the part at an angle, 45 degrees for example, and travels from the OD surface to the ID surface. The path it takes is called the first "leg". Following the law of reflection, the sound bounces off of the bottom at a 45 degree angle headed back toward the OD. This is...
Does anyone know of a standard or spec which describes this process? We are looking for grinding burns.

Can anyone with experience on VLCCs answer these questions?
1. Can you share some experience of climbing in these tanks eg, fixing points etc.?
2. Does the vessel supply an inflatable raft in the event of tank flooding (doing readings from the raft)?

You might try leak testing if you just trying to determine if they are leaking by or not. The equipment is cheap enough and simple to use. See these sites

If no sound hits the defect, no sound is reflected back therefore no detection. The angle of inclination varies with the probe design so you need to contact the manufacturer of your transducer to get the specifics. To learn more about transducer and UT in general visit this site...
You should probably check with your probe manufacturer. However, generally speaking, the crystals in TR probes are set in at an angle thereby "focusing" the beam at a certain depth and reducing the amount of beam spread. Normal probes with one crystal have more beam spread at a given...

ASTM 165 will explain penetrant inspection well enough to allow you to perform the inspection you are doing. I will suggest an additional technique typically used in these cases: if possible, apply the penetrant on one side and look for bleed out on the other. Bleed out indicates areas that...
