Titanium Grade 7 Flanges Manufacturer in India
Grade 7 Flanges made of titanium are characterized by a high resistance to corrosion coupled with high strength performance and an aggressive industrial environment. Titanium Grade 7 is an excellent choice as it has an enhanced resistance to reducing acids, and this is added with palladium; hence, it is used in severe chemical and marine environments. These flanges become very common in piping systems where performance, durability, and cost are critical issues. Titanium Grade 7 Flanges are used in chemical processing plants, desalination plants, offshore platform, power generation units, heat exchangers, pharmaceutical industries and oil and gas installations to ensure American leak-free connections and prolonged service.
What Are Titanium Grade 7 Flanges?
The Titanium Grade 7 is manufactured to ASTM B381 / UNS R52400 by using forged and rolled Ti-0.2Pd alloy. They have good mechanical performance, high corrosion resistance and consistent performance in high pressure and high temperature applications. These flanges are also light but very strong and can be used in important piping applications in chemical processing, marine engineering, offshore, power plants and other industries where safety, structural integrity and extended service life are the most important factors.

Application uses of Titanium Grade 7 Flanges
Titanium Grade 7 Flanges are commonly used in different industries because of their good resistance to corrosion, high strength and their ability to withstand severe conditions. They deal with very corrosive fluids in refineries, thus compromising the long-lasting performance of the pipeline. They are used in the oil and gas industry in offshore and onshore pipelines, valves and pressure vessels where the resistance to seawater, sour gas and high pressure is very important. They find application in heat exchangers, condensers and cooling systems in the generation of power and offer thermal stability as well as minimized maintenance. Their chemical resistance and the quality of ensuring the state of sanity in processing lines make pharmaceutical equipment useful. They are also used in the pulp and paper industry in digesters, bleaching plant and chemical processing systems that have to handle high-acidic and chloride environments. All of these and more challenging application needs are met with Titanium Grade 7 Flanges, which are a reliable and long-lasting solution.
Frequently Asked Questions (FAQ)
They are used in chemical processing, refineries, oil & gas, power plants, pharmaceutical, and pulp & paper industries, where corrosion resistance and durability are critical.
Grade 7 contains palladium, giving it better corrosion resistance in oxidizing and acidic environments compared to other grades like Grade 2.
They have excellent resistance to corrosion, especially from chlorides, acids, and seawater, making them ideal for harsh chemical environments.
Yes, they can be used in high-pressure piping systems, although the design should consider temperature and pressure limits.
The Grade 7 flanges are more corrosion-resistant due to palladium content, while Grade 2 is less expensive but suited for less aggressive environments.
