GLV-Galvanization

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. 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.

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.

Material-SS400

SS 400 Is A Structural Hot Rolled Steel For General Structural Applications. Its Designations Defined In JIS G3101 Standards.

“JIS” Stands for Japanese Industrial Standard and are published by the Japanese Standards Association (JSA) Provided in JIS2K, JIS5K, JIS10K, JIS16K, JIS20K, JIS30K, JIS40K and JIS63K pressure classes, it can be offered in Slip On, Blind, and Weld Neck varieties in Raised Face or Flat Face configurations.

Face Type-Flat Face

The Flat Face flange has a gasket surface in the same plane as the bolting circle face. Applications using flat face flanges are frequently those in which the mating flange or flanged fitting is made from a casting.

Flat face flanges are never to be bolted to a raised face flange. When connecting flat face cast iron flanges to carbon steel flanges, the raised face on the carbon steel flange must be removed, and that a full face gasket is required. This is to keep the thin, bittle cast iron flange from being sprung into the gap caused by the raised face of the carbon steel flange.
