Kencotube is a manufacturer & whole-seller for high quality Super Duplex Steel Flanges, which are recommended in order to obtain a weld metal with optimum corrosion resistance and mechanical properties. The presence of corrosive water and high temperatures means that Super Duplex Steel Pipe Flanges is the ideal material for desalination plants, making them easier and cheaper to build to the scale required. The starting force in these Super Duplex Steel Slip On Raised Face Flanges needed for bending is slightly higher than for standard austenitic stainless steels, where normal expanding methods can be used, but the expansion requires higher initial force and should be undertaken in one operation. Super Duplex Steel Blind Raised Face Flanges are useful for storing and handling acetic acid, especially in solutions where it is combined with formic acid and when aeration is not present.
Super Duplex Steel Weld Neck Raised Face Flanges is exposed to stronger bases such as sodium hydroxide at high concentrations and high temperatures will likely experience some etching and cracking, especially with solutions containing chlorides such as sodium hypochlorite. The difficult and damaging conditions frequently encountered when drilling for oil or gas mean that Super Duplex Steel Socket Weld Raised Face Flanges is the ideal material to manufacture vital components. The combination of strength, corrosive resistance and an ability to withstand the damaging effects of pitting and crevice corrosion in these Super Duplex Steel Lap Joint Flanges lead to a life expectancy far in excess of that achieved by standard steels.
