19 19 Does the target have a cast iron component that could fail?

Is moving pipe thicker than target pipe?

Has the interaction been geometrically analyzed, concluding target pipe damage is minimal?

Will not contribute significantly, does not warrant further investigation.

No Yes Can not conclude target pipe damage is minimal.

No Yes Is the target less than 4 NPS?

No 1

2 3

4 5

6 Has the interaction been evaluated in CCHELB SDP?

Is moving pipe normally isolated/

deenergized?

Yes No No Yes Yes No Yes AES analysis supports no target damage. Excluded from interaction set.

Not considered a piping interaction.

Excluded Exclude from SDP Exclude from this SDP
