Werner Flanges Inc. is one of the prominent exporters and suppliers of ASME B16.47 Class 300 Series B Welding Neck Flanges, which can be forged, hot-upset and impact extruded. As a known ASME B16.47 Class 300 Series B Flange Manufacturers in India, these are always important to assess the suitability of a particular with a full knowledge of the corrosive environment. Our range of ASME B16.47 Class 300 Series B Weld Neck Flanges Dimensions are widely used as heat exchangers in refinery industries, petrochemical plants, Pulp & Paper industries, Beverage & Sugar industries, and more.

As a Distributor of ASME B16.47 Class 300 Series B Weld Neck Flanges, it is stabilized against chromium carbide formation by the addition of columbium and tantalum. Since these elements have a stronger affinity for carbon than chromium in B16.47 ASME Class 300 Series B Flange Welding Neck Flange, columbium – tantalum carbides precipitate within the grains instead of forming at the grain boundaries.

Series B Class 300 Weld Neck Flanges should be considered for applications requiring intermittent heating between 800 Degree F (427 Degree C) and 1650 Degree F (899 Degree C) or for welding under conditions which prevent a post – weld anneal. Weld Neck Flanges ASME B16.47 Class 300 is non-magnetic and is stabilized by the addition of columbium and tantalum.
