Gayatri Tubes is the worldwide manufacturer, supplier and exporter of the SS 317 Fasteners.We are providing the fasteners in various specifications. Some of the specifications in which they are available are dimensions, shape, size, surface finish, end finish, and many others. We are also providing them in the cut made specifications given by the clients. National and international quality standards are also performed with the manufacturing of the fasteners in wide ranges. Fasteners are the hard devices that are used in the piping systems to attach various parts of the industrial applications. This is the great connector that affixes two parts together so that they perform the same task. However, these are the tools that are removed with the help of hand tools or power. The common fasteners that are used are the screws, bolts, and nuts. These are the best fasteners that connect the two parts of piping systems. They are also used to connect the two pipes with the help of pipe fittings.
SS 317 is the carbon version of stainless steel that is used for making the industrial used pipe fittings and fasteners. They are having good stability in the elevated temperatures. The fasteners are used in various industrial applications. Some of the industries in which the fasteners are used are petrochemical, pharmaceuticals, oil and gas, pulp and paper and many others. Even the threaded fasteners are also having many mechanical properties. They are having a good tensile strength that is good at supporting the parts piping systems. Along with the presence of alloy also provides the SS 317 Fasteners with many features. Some of the characteristic features that are there in the fasteners are corrosion resistance ability, great ductility, high weldability, tensile strength, and many more. Because of these characteristics, the fasteners are widely used in the industries. The clients also prefer to buy the fasteners that are manufactured by Gayatri Tubes.
SS 317 Fasteners are also tested by various tests. Some of the tests that are performed are hardness, hydrostatic, micro, macro, ultrasonic, positive material identifications, and intergranular corrosion resistance tests. The fasteners are also packed as per the expectations of the clients.
