We offer precise quality flanges to our local and international customers according to their requirements in different sizes, dimensions and several types such as blind, slip-on, weld-neck, orifice flanges. Our flanges are connected through Raised/Flat Face, Ring Type Joint, Large/small Male-Female, Lap-Joint, face types. Our Flanges are strong and tough to face different pressures as per the obtained class of flange. Our customers can obtain proper flanges through our collection or demand for custom-made requirements.
Navgraha Steel & Engg Company is widely spread in the global market, providing excellent quality flanges with outstanding performance. We use the best material in the formation of these flanges and offer at affordable rates. Alloy 28 Flanges are the best selected for applications in strong acids, hydrogen sulfide and chloride containing surroundings as it is excellently resistant to such a reducing media.
Alloy 28 is adaptable stainless steel with a Nickel-Molybdenum combination categorized with excellent corrosion resistance. It contains a number of surroundings, including strong acids and other harsh compounds. Alloy 28 flanges are utilized with pit free appearance and strength against cracking. It also withstands sulfuric and chloric acids. In addition, it reduces intergranular corrosion and shows excellent weldability.
Alloy 28 Flanges are super alloy flanges with excellent strength and best performance in high-temperature applications. This alloy shows outstanding resistance to oxidizing and reducing acids due to copper content. In addition, it demonstrates a good modulus of elasticity. Our Alloy 28 Flanges are used in the chemical and petrochemical processing industry and deep gas wells. It also shows usefulness in sanitary systems along with the construction, paper, chemical and automobile industries.
Navgraha Steel & Engg Company manufactures these flanges that are durable, leakproof, robust and long serviceable. We have a huge manufacturing unit with machines and tools with which we produce these flanges on a large scale. Our experienced professionals are dedicated to errorless production and meanwhile implementation of flanges. We maintain quality standards and conduct several tests to certify the flanges. We provide these flanges with timely delivery.
