Major NE Coast Oil Refinery Cat Cracker
Date: February 2006
Location: Northeast USA
Industry: Oil and Gas/Refineries
Challenge
A corroded and leaking underground 25” carbon steel cooling water pipe. Due to the leak, the cat cracker was not operational. Every day the Cat Cracker is not operational results in an approximate loss of one million dollars.
Solution
An effective yet efficient solution was required so the refinery could return the cat cracker to service. After digging up the pipe a belly clamp was constructed to encapsulate the damaged pipe section.
The clamp had a 4” stand off from the damaged section of pipe. Due to occasional temperature spikes between 250°F and 300°F SC5400 paste was used to seal the clamp. After the clamp to the pipe was sealed and the clamp was filled with the SC5400 paste and allowed to set.
As an extra layer of protection, the entire clamp was then wrapped with a cloth mesh fabric infused with SC5400. The corroded, leaking pipe was repaired and restored and the cat cracker was returned to service in record time.
The Novocoat team saved the refinery millions in lost revenue.
