TUBE EXPANDERS - BOILER & CONDENSOR
Tube expanders are specialized tools, manual or powered, that mechanically deform tubes (like copper or steel) to create secure, leak-proof connections with tube sheets in heat exchangers, boilers, and HVAC systems, or to flare/size pipes for fittings, effectively replacing couplings by expanding the tube's end to fit another component. They work by rolling or pressing internal rollers outwards, pressing the tube's outer wall against a fixed surface, ensuring tight, durable bonds crucial for pressure vessels.
