Failure of material for low temperature?

Failure of material for low temperature?

Failure of material for low temperature?

(OP)
What is the reason that can cause the failure of drine connected to chiller and made of steel resists low temperature condition? where the failure was a longtudinal crack.

RE: Failure of material for low temperature?

Numerous possibilities - material defect, internal freeze or ice plug, internal corrosion which thinned the material.... You want a definite answer? Send the failed drain line section to a lab for metallurgical analysis.

RE: Failure of material for low temperature?

(OP)
AS you mentioned the plug, the drain is plugged with hydrocarbons how this can cause such failure?

RE: Failure of material for low temperature?

As I said, have the failed piece analyzed. We have no idea what specifically caused the axial crack without an analysis.

RE: Failure of material for low temperature?

Some pictures of the failed one and some good ones would be helpful.
