How to Stop and Repair a Tank Live Leak

#Liveleaks and through-wall defects present major safety concerns to asset owners. This video demonstrates how live leaks on tanks operating at low pressures can be stemmed effectively by using Belzona 9611 (ES Metal). This rapid-curing epoxy is packaged as a stick and has been designed specifically to seal live leaks. The solution is then completed by bonding of a plate over the stemmed leak to achieve a permanent repair. This video mainly focuses on #howtobondmetaltometalwithoutwelding.

Leakage of potentially harmful solutions into the environment can prove problematic to both personnel and equipment in the immediate vicinity. 

Eliminating the health and safety risks associated with conventional cut and weld hot work, #Belzona cold-applied metal repair composites are simple to apply in situ without the need for specialist equipment meaning they can be easily applied by your maintenance team.

Materials Used:

To stop the leak, we used Belzona 9611 (ES-Metal) then to bond on a plate we used Belzona 1161 (Super UW-Metal)

How-to Guide:

Step 1: Prepare the surface using a simple grinding file.
Step 2: Clean the area to remove any dirt, grease and other contaminants.
Step 3: Cut off the required amount of Belzona 9611 and knead until a uniform color is achieved.
Step 4: Force the mixed material into the hole and apply pressure with a ratchet strap until the material hardened.
Step 5: After approximately an hour or once the material has fully cured, remove the ratchet strap.
Step 6: Roughen the entire area of the tank where a plate will be bonded using a grinder. 
Step 7: Again, clean the area to remove any dirt, grease and other contaminants.
Step 8: Mix Belzona 1161 as per the IFU until a uniform material was achieved.

Step 9: A Firmly apply the mixed Belzona material to the prepared area of the tank with a stiff bristled brush. Additionally, the material should be applied to the plate, pressing well into the surface and creating a sufficient build up in the center.
Step 10: Position the plate and firmly press it onto the repair area.
Step 11: Remove the excess material from each of the ladder’s feet and remove the masking tape to finish the application.
