galvanized floor flange dn20 fittings

Galvanized flange, is to prevent the surface of the flange from corrosion, prolong its service life, coated with a layer of metal zinc on the surface of the flange, the zinc coated flange is called galvanized flange. Galvanized flange according to the production and processing methods can be divided into: hot dip galvanized flange, alloyed galvanized flange, electric galvanized flange. Galvanized flange smooth appearance, no zinc tumor, burr, silver white; The thickness is controllable, no hydrogen embrittlement, no temperature harm, can ensure the mechanical properties of the material unchanged, good corrosion resistance, surface oxidation resistance, wear resistance, simple operation, convenient installation. Galvanized flange is widely used in petroleum, chemical, food, dairy, pharmaceutical, machinery manufacturing, sewage treatment, municipal water supply pipeline, medical and other industries of pipeline connection.

1, low processing cost: the cost of hot dip galvanized rust prevention is lower than that of other paint coating;
2, durable: in the suburban environment, the standard thickness of hot dip galvanized rust prevention, can be maintained for more than 50 years without repair; In urban or offshore areas, the standard Hot-Dip Galvanized rust protection layer can be maintained for 20 years without repair;
 3.comprehensive protection: every part of the plating can be plated with zinc, even in the depression, sharp corners and hidden places can be fully protected;
