Meraki Star Metals Oil & Gas Equipment Trading L.L.C. is one of the leading Carbon Steel Flanges manufacturers India and we produce flanges in different types and material grades. The carbon steel flanges have carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum and vanadium depending on the material grade. The Carbon Steel Pipe Flange Price List varies according to the material grade as well.

The WMASS Carbon Steel Flanges have different dimensions and strengths. The tensile strength is in the range of 485MPa minimum tensile strength and 250MPa minimum yield strength. The Flange ANSI B16.5 Class 150 is a medium pressure class of the B16.5 standard flanges. The materials used for the flanges range and the pressure classes range based on the nominal bore sizes and the wall thicknesses.
