Tutorial 2: Drilling tubes and hollow parts to galvanize them properly

When hot-dip galvanized, tubes and hollow bodies are immersed in molten zinc. If the tubes are not open, the part may explode in the zinc bath. The air contained in the hollow body can not escape. At the time of immersion in the bath of zinc at 450 ° the pressure rises and the room may burst! The piece can float on the zinc bath. The air trapped inside the room prevents it from entering the bath. Galvanization can not be performed. So what to do? For hot dip galvanizing, tubes and hollow parts it will be necessary to make holes of good size, in the right places that will allow the zinc and surface treatment liquids to circulate freely, and air to escape! So it’s up to you! Consult the Guide of Good Practices. And for personalized advice, contact the nearest GALVA UNION group site.
