[Procedure Explanation] Repair Method for Steam Piping Using Heat-Resistant Repair Putty

Repair Procedure Overview

Here are the steps for repairing a hole in steam piping with heat-resistant repair putty (photos are at the bottom of the page). 【Repair Process】 1: Surface Preparation Remove rust and old paint using scraping, and degrease with acetone or similar to eliminate oil, moisture, and dirt. 2: Filling the Hole Pre-fill the hole and prepare the surface. 2.5: Preparation of Glass Tape (if necessary) Used when the leakage pressure is high or when increased strength is desired. Cut to the required length in advance. 3: Application of Heat-Resistant Primer Apply around the repair area to reduce adhesive strength loss at high temperatures. 4: Preparation of Heat-Resistant Repair Putty (for two-component types) Mix in the specified ratio until the color and consistency are uniform. 5: Application of Heat-Resistant Repair Putty (First Application) For the first application, apply thinly and work it into the surface to enhance adhesion. 6: Use of Glass Tape Saturate the tape with heat-resistant repair putty and wrap it tightly with strong tension. 7: Application of Heat-Resistant Repair Putty (Second Application) For the second application, build up to approximately 5-6mm thick. 8: Shaping After gelation, lightly smooth the surface with a gloved finger dipped in a small amount of solvent. *For more details, please refer to the illustrations at the bottom of the page.
