Vishal Tube Industries is one of the leading Manufacturer of Inconel flanges in india, We are ISO Certified and best quality product Exporter of Inconel Alloy flanges in india. The resistance of the Inconel flanges to various oxidising substances such as nitrates, nitric acid, and oxidising salt is large. These flanges are helpful against localised corrosion, such as pitting, intergranular corrosion, corrosion of the crevice, and corrosion cracking due to stress. In combination with sufficient heat treatment, the addition of titanium to the alloy helps to stabilise the ASTM B564 Inconel Slip On Flange alloy against intergranular corrosion sensitisation. When exposed to moderate to high temperatures, even with a hot working temperature ranging from 1600o F to 2150o F, the nickel based Inconel Weld Neck Flange has strong mechanical properties. Inconel Blind Flanges have been used in the seamless tubing of the solar receivers by solar power stations using super-heated salt (potassium and sodium nitrate). In chemical process facilities handling mixed acids, both oxidising and reducing, these Inconel Socket Weld Flanges are used. Inconel Alloy Flanges resists a broad assortment of seriously polluted environments and is resistant to pitting and crevice corrosion.


Inconel Lap Joint Flanges are also used in chlorination plants up to 1000 degrees F and in plants with titanium dioxide. Our Inconel Ring Style Joint Flanges are certified to many different national and global specifications. Inconel Orifice Flanges are quickly manufactured (hot or cold) and can be attached using normal processes of welding, brazing, and soldering. A superalloy based on nickel is the alloy used to make Inconel flanges. In a wide variety of conditions, this superalloy not only exhibits outstanding oxidation resistance but also superior corrosion resistance. In addition, the Inconel Flanges could be used at temperatures ranging from cryogenic to a high temperature of 2000 ° F, since this alloy has excellent tensile strength and toughness properties. Compared to many other strongly alloyed nickel based materials, Inconel flanges have a high degree of formability, thus showing better weldability. Since these Inconel Weld Neck Flanges are likely to work, hardening should only be used at low cutting speeds and the cutting tool should be used at all times.
