Piping Offsets

Question 1

The travel is always ___ times longer than either the offset or the run.

Answer 1

1.414

Question 2

The ratio between the distance of the run and the offset are always ___ for any 45 degree piping offset

Answer 2

The ratio between the distance of the run and the offset are always equal for any 45 degree piping offset

Question 3

Equal distance between the pipes throughout the offset is known as ___

Answer 3

Equal spread

• Fittings will not line up vertically or horizontally.
• Fittings line up angularly 22 1/2 degrees

Question 4

Different differences between the travels and the straight run entering and leaving the offset is known as ____

Answer 4

Unequal spread.

• Fittings will line up horizontally or vertically
• Relies on basic 45 degree triangle

Question 5

*22.5 degree offsets
Side opposite = side adjacent(run) x \_\_\_
Side adjacent = side opposite(rise) / \_\_\_
Travel = rise x \_\_\_
Travel = run x \_\_\_
Or use Pythagoras

Answer 5

*22.5 degree offsets
Side opposite = side adjacent(run) x 0.414
Side adjacent = side opposite(rise) / 0.414
Travel = rise x 2.613
Travel = run x 1.082
Or use Pythagoras
