| Structural Reinforcement To Naphtha Tower With Belzona Technology | | | Industry:Oil & Gas (OILG) | | | Application: | | | Customer Location:Refinery, Brazil | | | Application Date:2012 | | | Application Situation:Naphtha Accumulator | | | Problem:Leaking naphtha due to the presence of holes in the inferior generatrix. | | | Products:Belzona 1511 (Super HT-Metal)
Belzona 1391 (Ceramic HT) | | | Substrate:Carbon Steel coated with fiberglass | | | Application Method:The surface preparation was carried out through abrasive blasting of the pre-fabricated parts and grinding of the fiberglass substrate and metal parts of the equipment. Then, Belzona 1511 was applied to the upper generatrix with a stainless steel reinforcement sheet for fastening the tie rods and sealing the plates of the lower generatrix. Belzona 1391 was injected in the lower generatrix for a better accommodation with regards to the peripheral imperfections of the fiberglass. | | | Belzona Facts:The naphtha accumulator has been previously repaired with fiberglass, a procedure that was not effective and displayed holes in the fiber. Belzona guaranteed to enclose the system with an operating temperature of 115°C and operating pressure of 400 gf/cm², exceeding several critical points, such as the location of the accumulator at the top of the tower at 86 m in height and hoisting 70 kg parts to the top. Inspection was carried out in February of 2015 and it was verified that the installed system is still working well. | | | Photographs Description
