B31.3 Severe does not allow I.P however Normal allows 1 ½" in 6" (38mm in any 150 mm of weld length) be careful of what code you are responding to.

Dear Senthil
If your code is B31.3, please refer to table 341.3.2 to get the answer. Incomplete penetration and surface porosity are not acceptable (no imperfection).
