Guaranteed on time delivery
Gayatri Tubes is one of the trustworthy exporter, manufacturer, supplier, and wholesaler of high quality SMO 254 Flanges. We provide flanges in all dimensions, diameters, lengths, thicknesses, radius, and also in all shapes and sizes as per our client’s requirement. We manufacture flanges by using international standards and specifications. SMO 254 grade is austenitic steel comprised of many chemical contents, chromium, nickel, nitrogen, molybdenum. This chemical composition is a super austenitic and has many properties like resistance to corrosion cracking, impact toughness, pitting corrosion resistance, crevice corrosion resistance, heat resistance. Because of molybdenum content, these flanges can easily work at the high temperature and shows strength. SMO 254 Flanges are available in different types such as welded flanges, forged flanges, and threaded flanges, weld neck flanges, weld long neck flanges, socket weld flanges, etc.
Flanges are designed to connect two pipe’s equipment together like a pump, valve, tubes, etc. SMO 254 Flanges are used in many industries and provide highly corrosive resistance. Spectacle blind SMO 254 Flanges have a titanium and nickel element and because of this element increases flanges’ property. The weld socket flanges have higher copper alloy compare to AL- 6XN alloy. The ring joint SMO 254 Flanges have a little amount of copper that provide resistance to corrosion in reducing atmosphere and also resistance to stress chloride. The weld neck flanges are easily worked at the hydrochloric environment and sulfuric acids because it is not affected very easily by acids. Threaded flanges have many features of heat resistance, rust-free, reliability, weldability, fabricability, easy to install, resistance to corrosion, etc. SMO 254 Flanges are used in number of industries like chemical industry, pulp and paper industry, marine industry, offshore and oil drilling industry, food process, gas process, oil and gas industry, petrochemical industry, etc. These flanges are also used in seawater application, boiler equipment, surgery equipment, because of its highly resisting property.
We apply many tests to ensure that our product quality like macro and micro test, chemical test, mechanical test, positive material test, hardness test, toughness test, impact test, eddy current test, strength test, flaring test, flaring test, etc. We provide different types of packaging facility according to our customer’s requirement.
