Minimum Setback
Setback is the distance from the entry point to where
pipe becomes horizontal (B1).
Minimum Depth
Because you must bend pipe gradually, entry pitch and
bend limits determine how deep the pipe will be when
it becomes horizontal. This is called the minimum
depth.
• To reduce minimum depth (D1), reduce entry
pitch. This also increases setback.
• To increase minimum depth (D2), increase
entry pitch. This also reduces setback.
NOTICE: If setback is too small (B2), you will
exceed bend limits and damage the pipe.
