Electrofusion Welding
-NUPI provides specialized electrofusion and butt fusion welding machines specifically designed for high-density polyethylene (HDPE) and polypropylene (PP-RCT) piping systems like SMARTFLEX, NIRON, and ELOFIT. Unlike standard metal welders, these units use electrical currents to heat internal resistances in pipe fittings, creating a permanent, leak-proof bond
