Pipefitter Rigging, Hangers, and Supports 4

Question 1

Which type of pipe support is specifically designed to allow pipe movement in one direction while restricting movement perpendicular to that direction?

Accepted Answer

Guide

Answer

A pipe guide permits axial movement along the pipe run while restraining lateral (transverse) movement.

Question 2

What is the minimum safe working load (SWL) rating a shackle must have when used to lift a 4,000 lb pipe spool?

Accepted Answer

4,000 lb

Answer

The SWL of any rigging component must be equal to or greater than the total load being lifted; 4,000 lb is the minimum acceptable rating here.

Question 3

A three-point hanger rod assembly uses a turnbuckle primarily to:

Accepted Answer

Allow fine adjustment of rod length and pipe elevation

Answer

Turnbuckles allow field adjustment of the hanger rod length to set the pipe at the correct elevation.

Question 4

When rigging a long horizontal pipe spool for lifting, spreader bars are used to:

Accepted Answer

Keep the sling legs vertical and prevent crushing the pipe

Answer

Spreader bars maintain vertical sling legs, eliminating inward compressive forces on the pipe that could cause deformation.

Question 5

Which ASME standard governs the design and selection of pipe hangers and supports in power piping systems?

Accepted Answer

ASME B31.1

Answer

ASME B31.1 (Power Piping) includes requirements for pipe support design, spacing, and installation.
