Gayatri tubes are the leading and the most prominent manufacturer, supplier, and wholesaler of SS 317 / 317L Pipes. We make these pipes in various forms and dimension that too by following all the standards which are national as well as international. The standards are followed so that we can ensure that the pipes which are supplied to the manufacturer are of the highest quality and can be put to use in various applications ion industries. Hence we ensure that the pipes we manufacture are highly durable and are capable of providing a long term work life. Furthermore, there are several grades in the pipes which give these pipes varying characteristics that make them all different from each other. The variation is in place for serving different applications in different industries. The characteristics that are included with the different grades are the resistance to corrosion due to crevices, resistance to pitting, etc. moreover; there is resistance to the corrosion which happens due to the intergranular particles. This is a highly demanded property in the industry that our pipes are capable of providing.
Our collection of SS 317 / 317L Pipes is capable of working at elevated temperatures too. In that case, they are useful for the application that requires high tensile strength and high-stress rupture properties. Hence we provide these pipes in varying shapes and sizes. We also perform several tests on our products so that we can ensure that they are of the best quality. Therefore, we perform tests like pitting resistance test, PMI, IGC test, flattening test, and a lot more. These tests are highly important for the pipes that we manufacture.
The pipes that we manufacture are the ones that pass all these tests with complete reliability. Furthermore, we serve pipes in various different forms such as welded, LSAW, EFW, ERW, and fabricated pipes. We make these pipes in a large set of shapes such as rectangular, hydraulic press, round, square, coiled, etc. they all are either threaded, plain, or have beveled ends.
