| Belzona Saves Refinery $50,000 | | | Industry:Fluid Flow (FLOW) | | | Application:Heat Exchangers (HEX) | | | Customer Location:Refinery - Sweeny, Texas USA | | | Application Date:January 2003 and January 2008 | | | Application Situation:Multiple heat exchanger components severely damaged by erosion/corrosion. | | | Problem:Galvanic corrosion and erosion resulting in loss of thickness and gasket sealing surfaces. This allows for working fluid to bypass portions of the multi-pass exchanger thereby greatly decreasing the efficiency of the heat exchanger. | | | Products:Belzona® 1111 (Super Metal)
Belzona® 1321 (Ceramic S-Metal) | | | Substrate:Carbon Steel | | | Application Method:Belzona® 1111 and Belzona® 1321 were applied in accordance with Belzona Know-How System Leaflet HEX-2. | | | Belzona Facts:Conventional repair involves weld build up followed by the machining of new gasket surfaces at a cost of $2,500-$5,000 per dollar plate. The Belzona solution costs less than half of the conventional repair. This results in cost savings of more than $50,000 per unit turnaround. | | | Photographs Description
