HI

There is no reference in the API 1104, but you have to got permission from the existing pipeline owner, who can give direction about the clearance between new and existing pipeline, because of pipeline details such as pressure, velocity, kind of medium and exiting pipeline coating systems to be given by them. those all times shall be considered during the excavation. 

Kindly get advise from your designer... 

Thanks and regards,

When crossing an existing pipeline, best practice demands that the new pipeline should be crossed below the existing to avoid upheaval buckling of the new pipeline since the top soil is already tampered. In that case a minimum safe distance should be maintained.
