Note:
All references to pipe components and tube in this section apply equally to hanger
components and rod.
The extent of the misalignment between two adjacent piping components may be measured using any of three parameters: the offset distance between their respective p-arrive and p-leave axes; the displacement angle between their respective p-arrive and p-leave axes; or the ratio of the offset to the projected distance between the arrive and leave p-points (which is equivalent to the tangent of the angle parameter). See Figure below.

TOLERANCE OFFSET ANGLE RATIO MAXANGLE
Description
The TOLERANCE commands specify the maximum offset, angle or ratio misalignments that will be allowed between adjacent components before a diagnostic message is output.
Examples |
|
|---|---|
|
TOL OFFSET 1 |
Maximum pipe misalignment is 1 mm offset |
|
TOL OFF 1/4 INCH |
Maximum pipe misalignment is 0.25 inch offset |
|
TOL ANGLE 0.0573(Default) |
Maximum angular misalignment is 0.0573 degrees (i.e. 0.01 radians) |
|
TOL RATIO 0.001 |
Maximum offset/separation ratio is 0.001 |
|
TOL ANG 1.5 |
These are equivalent angular settings, since 0.0262 is the tangent of the angle 1.5 degrees |
|
TOL DEF |
Resets all misalignment tolerances (Offset, Angle and Ratio) to their default values |
|
TOL MAXANG 90 |
Maximum permitted design angle for pulled bends and elbows can be set to values from 0° (straight tube) to 180° (U-bends). |
