lack of penetration is straight rejection as per asme sec VIII. But in api 1104 it is having acceptance limits. Is there any other defect for example which may lead to change as per code.
Is this for UT acceptance criteria?...and if so, is height relevant to acceptance... doesn't Code state that any Individual indication with a height greater than 25% of material thickness a defect?...and if so, would length no longer matter?
Clause 7.8.2 states "At no point shall the crown surface fall below the outside surface of the pipe, nor should it be raised above the parent metal by more than 1/16 in. (1.6 mm)." Low cap can be called: A. If the above clause is not met. B. As shown in a customer specification that complies with 7.8.2. Also note that the phrase 'nor should it be raised above the parent metal by more than 1/16 in. (1.6 mm)' is a recommended practice and not a requirement.

I've seen company specifications limit cap height to 0.100" or 0.125" for fatigue purposes.
Hi isn’t section 13.8.4 showing that “outside diameter weld reinforcement shall not be raised above the parent material by more than 3mm”. 2mm if its the root.

For cross country pipeline which standard is used
API 1104
Sir could you share your email ID
as per api 1104 cap hight how much mm?
Clause 7.8.2 states "At no point shall the crown surface fall below the outside surface of
the pipe, nor should it be raised above the parent metal by more than 1/16 in. (1.6 mm)."
Low cap can be called:
A. If the above clause is not met.
B. As shown in a customer specification that complies with 7.8.2.
Also note that the phrase 'nor should it be raised above the parent metal by more than 1/16 in. (1.6 mm)' is a recommended practice and not a requirement.
Thank you sir. Please tell us about capping/reinforcement as per API-1104.
With Reference no. Thanks again
