Gayatri tubes is a prominent manufacturer of all ferrous and non ferrous product with high quality. We are supplier, exporter, and wholesaler of SS 316 / 316L / 316H Pipe Fittings and other products as well. We supply pipes fitting in all dimensions, diameters, thicknesses, lengths, according to our customer’s demand. We used international standards and specifications during the manufacture of our product. The stainless steel grade 316 is a nickel-chromium wit includes austenitic and molybdenum. This addition of chemical content increases its corrosion resistance to pitting chloride; improve strength, at high temperature. And also resistance to many acids like sulfuric, acetic acids, and alkaline chloride. The grade 316l is an updated version of grade 316 and has low carbon content with austenitic chromium-nickel steel. Grade 316h has high carbon content and used in high-temperature applications. Because of higher carbon alloy, the grade 316h improves yield and tensile strength and shows high toughness at the cryogenic temperature.
The pipes fittings are used to join two pipes and tubes of the same dimension and sizes. Pipes fitting have many types like elbow pipe fitting, reducer, forged pipe fitting, butt weld pipe fitting, reducer pipe fitting, elbow pipe fitting, type T pipe fitting, etc. All types of pipes fitting are used in different application and have different properties. We manufacture Stainless Steel S31600, S31603, S31609 Pipe Fittings in all sizes and shapes and have excellent corrosion resistance property in reducing the environment. The stainless steel 316/316s/316h pipe fitting has many properties like corrosion resistance, resistance to chloride cracking, heat resistance, reliability, easy to use, weldability, formability, etc.
The SS 316 / 316L / 316H Pipe Fittings have many applications like used in many industries such as chemical industry, oil, and gas industry, petrochemical industry, paper, and pulp industry, nuclear industry, and many others industry. The pipe fittings are used in many processes like gas process, chemical process, food process, seawater application, marine industry, and so on. We offer the best packaging facility in different forms like polybag, plastic wrap, carton box, wooden box, etc. We apply many tests like a mechanical test, chemical test, hardness test, toughness test, destructive test, impact test, etc.
