Gayatri Tubes is known for manufacturing the best SS 316 / 316L / 316H Flanges all over the globe. We also supply and export these flanges to our worldwide customers. SS flanges have the same properties as that of SS 304 austenitic stainless sheets of steel. Their fabrication, physical and mechanical properties are similar. This austenitic steel contains chromium and nickel that add corrosion imperviousness to the alloy. The high carbon change in alloy offers the ability to perform in raised temperature administration. Molybdenum containing flanges improves their ability to perform in marine and chemical corrodents environments. This makes them ideally suitable in elevated temperature and superior corrosion-resistant applications.
Furthermore, in environments like inorganic and organic their resistance level is higher than others against these chemicals. Hence, food and beverage industries use SS 316 / 316L / 316H Flanges. The alloy infuses more properties to the flanges that are sustainability against high temperature and pressure load, tensile and hardness. The SS 316 flanges have more product features such as they excellently distribute stress on the load. The transition from pipe thickness to flange ends run smoothly. Also, flanges have rustproof finish, accurate dimensions, and more.
We cater to the needs of the client for SS slip-on flanges, threaded, socket weld, reducing, weld neck, blind and more types of flanges. Applications such as power plants, gas stations and thermal plants use threaded flanges. Applications where Water and air are used also prefer these flanges. However, socket weld flanges are useful in high-pressure piping. Blind SS 316L flanges are useful in applications where mechanical stress is remarkable. In pressure vessels, they are used as manholes.
Moreover, unbolting blind flanges are easier than other flanges. Operators can thus perform the activities inside the pipe terminal. We also serve uncommon types of flanges like nipoflange, weldoflange, latroflange, elboflange, and more. Less common type that is used in the industry is elboflange that branch a pipeline to a degree of 45. Industries like water management, petrochemical, other where water, oil, gas, chemical and hydrocarbons fluids are transported use swivel flanges. All the various types perform similar functions of connecting pipes but differ in the applications in which they are used.
