Copper Nickel Flanges Manufacturer in India
CuNi Blind Flanges are available in different finishes
Prashaant Steel and Alloys are largest Copper Nickel flanges manufacturer in India. Our company carries a rich experience of manufacturing and supplying CuNi flanges and aims to deliver long-lasting, corrosion-protected, and high-performance flanges that fit the strictest industrial requirements. PSA is manufacturer of DIN 86037 Flanges in various types such as Slip on, Weld neck, blind and socket weld flanges.
Cu-Ni blind flanges are famed for their greater resistance to corrosive conditions especially seawater and conditions associated with salt content, thus becoming the most suitable for such conditions. Moreover, it is easy to work and provides high resistance to stress corrosion cracking’s SCC, pitting, and crevice corrosion, and therefore Cupro nickel alloy RTJ flanges are very viable and strong even in harsh environments. By providing high quality, long life, and reliability CuNi alloy lap joint flanges, Prashaant Steel assures quality that will remain unhampered even when the equipment is used in the most severe conditions. We offers quickest delivery in Algeria, Peru, Mexico and UAE of EEMUA 145 UNS 7060X flanges in different pressure rating. We manufacture these CuNi flanges in ASME B16.5 standard
In the manufacturing of Cunifer blind flange, the material is tested, its dimensions checked and its surface treatment follows strict specifications in order to meet its highest performance requirements. Available with world class technology our flanges pass through rigorous tests, such as hydrostatic testing, visual testing, and other non-destructive tests to ensure the quality and reliability of the product. Cupronickel Long Weld Neck Flange do not disappoint when it comes to bearing mechanical stresses and mechanical strain on piping systems. They are designed to provide a good seal and mechanical connection so as to minimize leakage or failure of essential piping systems.
This feature can be attributable to the fact that CuNi alloy Orifice Flange have optimal thermal stability which is important for operations in extremely fluctuating temperatures as seen in those structures used in desalination plants and power producing industries where high temperature fluids are used. Cupronickel Flange can also be machined therefore further adjustments can also be made and furthermore it has special configurations.
