Guaranteed on time delivery
Gayatri Tubes is one of the best manufacturers, suppliers, and wholesalers of SS 316 / 316L / 316H Pipes. We fabricate these pipes in different dimensions according to the standards of national as well as international importance. Such standards ensure the quality of pipes to be used in various industrial settings. Therefore, durability and long term service of these pipes are ensured. Moreover, the grade we use ensures that the pipes offer great characteristics that are in demand by the various industries. These characteristics include the crevice corrosion ability, pitting and corrosion resistance. The resistance against intergranular corrosion is required in some critical applications which are ensured by using proper manufacturing practices.
Even at elevated temperature, our SS 316 / 316L / 316H Seamless Pipes are useful because of high-stress rupture and tensile strength properties. Therefore, we serve patrons different dimensional pipes that vary in their thickness and sizes. However, the desired quality of pipes is assured after proper testing after production. All the pipes undergo various tests like PMI, pitting resistance test, flattening and IGC tests that are mandatory for the pipes. Only 100 percent of tested pipes are delivered to the clients. We also serve LSAW, welded, ERW, and EFW, seamless and fabricated pipes. Various shapes are available at us such as rectangular, coiled tubes, hydraulic, square, round and more. All the pipes either have threaded, beveled or plain end.
The pipe is made from marine-grade stainless steel that is SS 316 / 316L / 316H. SS 316 is the standard version whereas the other two are its subcategory that has a varied composition of carbon. This different composition gives different properties to each grade making them suitable in different industries. The low carbon content steel that is SS 316L offers high corrosion-resistant ability. However, the superior resistance against IGC is also offered which is not seen in SS 316 pipes.
Other properties like tensile strength, hardness, oxidization resistance are also served by the pipes. Hence, the pipes are useful in industries like oil and gas, thermal, nuclear reactor, LNG, chemical, petrochemical, pharmaceutical industries. For longer service and safe delivery, we pack the SS pipes in good quality materials.
