My house is their own after the change of geothermal, is now paved finished, and some of the lines when the electricity to go on the ground, I am worried that there will be signs of aging caused by circuit fire. Also, if the future of the cable problems can also be re-threading the same way? Looking forward to your reply, thank you! More
Hot galvanized steel pipe: 1) color hot galvanized pipe a little white, 2) Weight: 6 meters long 65 kg (corrosion resistance, long life, the price is slightly higher); hot galvanized steel pipe white but not hair (Hot-dip galvanized steel pipe) is to make the molten metal and iron matrix reaction to produce alloy layer, so that the substrate and the coating The combination of the two Supply of hot-dip galvanized steel pipe is the first pickling, in order to remove the surface of iron and steel iron, pickled, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed water tank cleaning, And then into the hot dip bath Hot galvanized with uniform coating, strong adhesion, long life and other advantages Hot-dip galvanized steel pipe matrix and molten bath complex physical and chemical reactions, the formation of corrosion-resistant structure of a close zinc alloy layer Alloy layer and pure zinc layer, steel pipe body integration So its strong corrosion resistance
5 kg (slightly less corrosion resistance, life than hot galvanized steel pipe life is short, low price economy) The Galvanized tube white shiny and reflective, very few snow-like, two-port clean zinc-free tumor
WDZ and WDZC are the combustion characteristics of the cable, both halogen-free low smoke flame retardant cable, but the former is a single vertical flame retardant test, which is bundled combustion C class flame retardant test, but the flame retardant The requirements are not the same.
