Texas Flange offers a full range of galvanized flanges for our customers. Galvanization is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of molten zinc. For this reason, we stock a line of hot dip zinc galvanized flanges to ASTM A123 and ASTM A153, and we can provide many custom items with this protective coating as well. Here are a few noticeable advantages to galvanization:
Protection from Elements
Galvanized flanges are superior to exposure to the elements versus painted carbon steel. They offer longer life cycles in many cases as well, due to their resistance to corrosion from rain and other naturally occurring weather/climate issues.
You will often have more use and shelf life from galvanized flanges in comparison to uncoated carbon steel and ductile iron, due to the metallurgical bond present between the zinc coat and the actual steel. This provides excellent protection from physical damage to the flange in question.
Limited Base Exposure
A zinc hot dip coating on flanges and steel components per ASTM standards is superior to regular plating, which may leave exposure for crevices, machined surfaces, and some difficult to reach portions of the flange in question. The process provides noticeably more zinc coating than regular plating.
Commodity hot dip galvanized flanges can provide a good alternative to stainless and chrome alloys from a cost benefit perspective. This depends, though, on your specific application. If the superior chemical requirements of certain jobs do not apply, they are an excellent alternative to standard carbon steel flanges.
However, there are some possible disadvantages to galvanization.
Some steel pieces are too tiny or too huge to be hot-dipped, and it doesn’t make sense to galvanize them using other methods.
Zinc can tend to be temperamental during the actual galvanization process. It’s important to take enough time to let galvanized steel cool down, so that the zinc doesn’t peel off. Galvanization isn’t as effective if the zinc is not binding to the steel. The right coating thickness must be applied.
