API 650 clarification

API 650 clarification

API 650 clarification

As per the image attached , In the code API 650 , item , there is a phrase " the lap need not exceed 25 mm " , so does this mean if we exceeds the 25 mm there is no problem ? Also if the weld is single-welded lap joint and the lap is 50 mm is that accepted ?

RE: API 650 clarification

If the lap is longer than 25mm, there is no problem.
If a single-welded lap joint is 50mm, that is okay.
It is common practice to dimension laps wider than the minimum to allow for tolerances in plate dimensions and in plate placement.

ok thank you
