6-5/8" Drill pipe minimum bevel diameter

[Maciam]

Challenging the DS1-CAT 3-5 Inspection findings that is failing most of our nearly new Drill pipe.
DS1 CAT 3-5 is the inspection criteria that's being used to inspect our drill string of 6-5/8" FH 34.2 lbs/ft VM-140 drill pipe.
8-1/2" OD tool joints 0.522 wall thickness tube.
Pin ID 4.25" Box ID 4.75".
Does anyone have the minimum bevel OD criteria? TH Hill specs not 100% capturing the pipe specifications.
Drill pipe bevel wear, even though the bevel is an angle, the wear on the bevel can effect the connection seal face and is measured in OD.

Can you provide some translation of this please?

What is DS1-CAT 3-5 failure?

What code / spec are you using? API 5L CT?

Bevel is an angle, not an OD.
Can you sketch out what the missing data is please? Or indeed what your question / problem is.

which bevel are you referring to?

I've always found that drill pipe is a strange place dependent on bespoke vendor specs.

The DS1 inspection is an industry standard, but which standard is 3-5? Is it 3 or 5?

What exactly is it failing on? The DS1 simply says to measure things, not what the pass/ go measurement is.

That can only come from the vendor of the connection, which you don't specify.

You should be able to work out the OD at the bit where it says see detail A using the slope and the pin nose diameter plus a bit for the thread.
