Galvanized flanges

Use of galvanized flanges

GB flange is mainly used to connect pipes and pipes. According to the structural type, there are integral flanges, looper flanges and threaded flanges. Common flange has plain welding flange and butt welding flange. Flange fittings refer to fittings with flange (flange or flange). It can be made by casting or threaded or welded. The flange joint is composed of a pair of flanges, a gasket and a number of bolts and nuts.

Hot-dip galvanized flange has good corrosion resistance. It is made of formed rust removal and immersed in melted zinc solution, so that the steel components are coated with zinc, thus playing the purpose of corrosion protection.

The principle of hot-dip galvanizing is that the iron is cleaned, then the solvent is treated, dried and immersed in the zinc solution. The reaction between iron and molten zinc produces an alloyed zinc layer. The process is degreasing-washing-pickling-assisting plating-drying-hot dip galvanizing-separation-cooling passivation.

The technological features of galvanized flanges are:

1. optimization of sulfate zinc plating

Transformation of 2. sulfate zinc plating

3. fast deposition rate and excellent protective properties.

4. unique cleaner production

5. particularity of plating equipment.
