Before electrofusing a pipe, it is important to prepare the surface of the pipe by cleaning it thoroughly. This typically involves using a special cleaning tool to scrape away any dirt, debris, or oxidation that may be present on the surface of the pipe. The pipe should then be wiped down with a clean, lint-free cloth to remove any remaining debris. After the pipe has been cleaned, it is important to check the pipe ends to ensure that they are square and free of any burrs or other irregularities that could interfere with the electrofusion process. This preparation is important to ensure that the electrofusion process creates a strong and reliable bond between the two pipes.
