How to Setup a Rigid Hanger

Pipe hangers can withstand the load of the pipe and avoid friction loads associated with resting supports. Designed at an appropriate length that keeps angulation due to horizontal movements within an acceptable range, they are very versatile and there can be found many installation solutions.

Basic Setup

Before proceeding, check Understanding Support Datasheet topic for a better knowledge on information architecture.

Step 1: Enter basic data

• First of all, select ‘Rigid Hanger‘ on ‘Type of Support’ combo box.
• Define ‘Single/Double Type’ configuration (if double, select how you will enter loads on ‘Load Calculations’ field, by support or spring).
• Enter ‘Operational Load (Hot Load)’ value.
• Enter ‘Vertical Movement (+/-)’ value. Positive or negative values are allowed.

Advanced Setup

When a rigid hanger is appropriate

A rigid hanger carries the load without accommodating vertical movement. It is the right choice where the vertical thermal displacement is negligible — and the wrong choice where it is not, because it will resist the movement rather than follow it.

If the vertical movement is anything other than very small, use a spring support.

Rod capacity

The rod size follows from the operating load.

Hydrostatic test

The check compares the hydrotest load directly against the rigid hanger allowable for that thread size. On a double support in per support mode, both the operating load and the hydrotest load are halved before comparison.

See Hydrostatic test check.

Long rods

Above a threshold length the rod is supplied in sections joined by couplings. Each split adds a coupling and two hex nuts to the bill of materials, doubled on a double support.

See Rods, take-outs and weights.

Deviation angle

Rigid hangers hang, so the deviation angle applies. If the pipe has horizontal movement, check the angle warning before accepting the design.

See Vertical deviation angle.
