Application Method:

Belzona 9611 was applied into the immediate leak area with a clamp to hold it in place during curing.

The pipe was then reinforced with Belzona 1111 to complete the repair.

 
 

Belzona Facts:

The only alternative to the Belzona solution would have been to shut down the plant, as this vessel was reducing gas pressure for the whole plant. A shutdown would have cost millions in lost production, so it was critical to keep the plant running. Conventional welding repairs were not an option due to the gas leak. Due to the good ongoing relationship the customer, they wanted to try a cold-curing repair which worked exceptionally well. The application duration was one working day and they inspected the repair by a gas detector device. The distributor had been working with this customer for 15 years and carried out many successful applications including: leak sealing, process vessel lining, pump repair, heat exchanger repair and coating. This customer’s maintenance team also use Belzona for their day-to-day maintenance applications.
