Combination Rolling Offset
Unlike a regular rolling offset, the entry and exit ttings for a
combination rolling offset are on different planes and therefore
have different tting angles from each other.
Horizontal to Vertical
Find the pipe length, and entry and exit tting angles for a
combination rolling offset with a vertical pipe exit, given a
Roll of 23”, Offset of 15”, and Advance of 29”. Use the box in
Diagram 1 to review the entry and exit pipe perspectives.
