Gayatri Tubes is one of the leading manufacturer and supplier of Alloy Steel F1 Flanges. We are an exporter and wholesaler of all types of flanges with different grades. We provide flanges alloy steel in different types, sizes, shapes, dimensions, diameters, specifications, with different lengths, thicknesses. To manufacture our product we used international and national standards and specifications.
Alloy steel is a combination of many chemical contents like chromium, nickel, molybdenum, zinc, cobalt, copper, titanium, etc. The combination of the chemical element the alloy steel provides good mechanical properties. The alloy steel is divided into two parts on the basis of its chemical content low alloy steel and high alloy steel. There are many types of Alloy Steel F1 Flanges available like weld neck flanges, socket weld flanges, long neck weld flanges, reducer flanges, socket weld flanges, forged flanges, welded flanges, threaded flanges, etc.
Alloy Steel F1 Flanges are basically designed to connect two pipes and their equipment together which have the same or different dimensions. The alloy steel F1 slip-on flanges are totally depended on the chromium element for corrosion resistance. Threaded alloy steel flanges have maximum chromium content and it is easily worked up to 870 C degrees temperature. Weld neck flanges bear acid attack and used in an acidic environment and also it is used in high temperature and pressure application. The forged alloy steel flanges offer many features that are corrosion resistance, resistance to crevice corrosion, heat resistance, pitting resistance, durability, easy formability, weldability, and many more. Blind flanges provide high strength and toughness at the low temperature and at the cryogenic to high temperature.
Alloy Steel F1 Flanges are used in various industries like chemical and petrochemical industry, pulp and paper industry, food process, boiler equipment, seawater application, offshore and oil drilling company, etc. The alloy steel flanges are also used in surgery equipment, marine application, power generation, heat exchanger, gas processing, and many more.
We conduct various types of tests like a chemical test, mechanical test, hardness test, toughness test, strength test, impact test, eddy current test, flaring test, flattening test, and many other tests. We offer the best packaging facility like polybag, bundle form, carton and wooden box, etc according to customer’s requirement.
