Case Study of Implementation: Pump Casing Corrosion Repair - Introduction of Repair Examples
Super Metal (Belzona 1111) Super Metal Glide (Belzona 1341)
Super Metal and Super Metal Glide are repair agents with excellent seawater resistance. They are used for repairing pump casings that have been corroded by seawater.
[Construction Method] □ Surface Preparation: Protect non-coated areas and perform roughening through blasting. High-pressure washing is recommended to avoid adhesion failure due to seawater infiltration into the casing. □ Degreasing Cleaning: Remove moisture, oil, and dirt with a cleaning solution. □ Coating 1: Areas of reduced thickness on the flange surface due to gap corrosion will be repaired with Super Metal (Belzona 1111) (see construction photos below for reference). If there are deep areas of reduced thickness inside the casing, build-up coating will be applied. □ Coating 2: Apply two layers of Super Metal Glide by brush to the inner surface of the casing. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ [We will introduce examples of pump casing repairs.] If you would like examples of repairs, please fill in "Request for Pump Casing Repair Examples" in the "Contact Us" section below and send it.
