Cleaning the fusion surface is a critical step in preparing
socket fusion HDPE fittings for welding to ensure proper fusion and a leak-free joint. Here's what is typically done to clean the fusion surface:
Deburring: HDPE fittings are manufactured with clean, smooth surfaces to facilitate fusion bonding. However, minor imperfections such as burrs or rough edges may still be present due to the manufacturing process. Prior to fusion welding, these imperfections are removed through deburring using a suitable tool, such as a deburring knife or scraper. This helps to ensure a uniform mating surface without any irregularities that could interfere with the fusion process.
Cleaning with Solvent: After deburring, the fusion surface of the HDPE fitting is cleaned using a compatible solvent or cleaner to remove any contaminants, dirt, or grease that may be present. This step is essential for promoting proper adhesion between the fitting and the pipe during fusion welding. The solvent is applied to the fusion surface and wiped clean using a lint-free cloth or disposable wipe to ensure a clean and dry surface.
Visual Inspection: Once the fusion surface has been deburred and cleaned, it undergoes a visual inspection to ensure that it is free from any visible defects, contaminants, or foreign particles. Any remaining debris or imperfections are removed using additional cleaning methods as necessary to achieve a clean and smooth fusion surface.
Preparation of Pipe End: In addition to cleaning the fusion surface of the HDPE fitting, the corresponding end of the HDPE pipe is also prepared in a similar manner. The pipe end is deburred, cleaned with solvent, and visually inspected to ensure it is free from any contaminants or irregularities that could affect the fusion process. Both the fitting and pipe end must have clean and smooth fusion surfaces to achieve a strong and leak-free fusion joint.
By properly cleaning the fusion surface of socket fusion HDPE fittings and preparing the pipe end, installers can ensure optimal fusion bonding and the creation of a strong and reliable joint that is resistant to leaks and other defects.
