What Is A High Hub Blind Flange?


High Hub Blinds Flanges are considered to be an ideal choice, particularly because it offers excellent chloride ion stress related corrosion and chloride pitting corrosion. In addition to this, duplex stainless steel grade flanges provide a higher tensile strength in comparison to standard austenitic stainless steel High Hub Blinds Flanges, which although are more cost efficient and versatile have lower corrosion resistant properties. Although in the stainless steel categories, alloy grade 316 is referred to as marine grade by high hub blind flange manufacturers in India, due to its ability to resist corrosion when exposed to brine, sea water as well as marine environments.

What Is A Tapped Blind Flange?

Tapped Blind Flange are predominantly used to close ends of a piping system. This Drilled Tapped Blind Flanges is a type of a round plate without a centre hold, although these flanges are produced with all the proper bolt holes. Tapped Hub Blind Flange are used in order to provide positive closer at the ends of pipes, valves as well as equipment nozzles. These Tapped Blind Flange, we produce are available across the market in various sizes and different materials. This can be customised depending on the client’s needs or the specification the Series A & B Tapped Blind Flanges have been ordered in. For instance, Nickel Alloy 200 Tapped Blind Flange is used when the application’s primary requirement is exceptional resistance to corrosion from caustic alkalis at varying concentrations and temperatures, especially at elevated temperature settings.
