Nishra Overseas LLP is a renowned manufacturer, supplier, stockist, and exporte of Nickel Alloy Flanges. We supply our products to clients worldwide. Nishra Overseas manufactures these flanges in accordance with all relevant national and international quality standards and recommendations. All of our products have outstanding and precise applications since we are very accurate and precise about their size, thickness, and measurements. We provide our customers the option of customizing their orders according to their needs. Since nickel alloy flanges have minimal magnetic characteristics and great durability down to 450 degrees Fahrenheit, they are frequently used at cryogenic temperatures. In order to achieve the highest corrosion tolerance in these alloy flanges, cold-worked components must be re-annealed with an outer fiber elongation of 7% or more.
We use the best premium nickel alloys and state-of-the-art techniques to make High Nickel Alloy Flanges in accordance with industry standards. Our Ni Flanges provide high strength, corrosion resistance, durability, outstanding surface quality, chemical resistance, consistent performance, a longer functional life, and other benefits to ensure efficient performance in a wide range of industrial applications. Additionally, before being shipped, our quality professionals extensively inspect and test our nickel alloy flanges to a number of quality requirements. Oil field, offshore, water system, marine, natural gas, electric power, pipe projects, pulp and paper, research & development, mega projects, defense, development, and other industries are among the many industries that use these nickel alloy flanges.
Nickel Alloy Flanges are specifically designed for a variety of piping applications across multiple industries. We also have a reputation as one of the biggest suppliers of high-quality nickel alloy flanges, nickel alloy tube tees, nickel 200 fasteners, UNS N02201 nickel alloy flanges, nickel alloy UNS N02201, nickel alloy forged tube, and many more items. In the pipe fitting industry, nickel alloy flanges are considered to be one of the most important components. We also have a reputation as one of the top suppliers of Monel Flanges.

Every Standards have clearly requirements for steel flanges’ marking style, usually the marking words include seller’s Logo, buyer’s Logo (OEM), standard number, flange’s type, flange’s pressure, flange’s size, flange’s material, place of origin, heat number and other words for convenient to trace. If the flanges repaired by welding, it must mark on flanges showing this flange repared by welding. If the flange’s dimensions (OD, ID, PCD, Thickness, Holes number, Holes diameter, Tolerance etc) are different with the normal standard, it also must mark on flanges where it is different with normal ones. Another important place is heat number marking, it is the tracing base for every piece flange, and from the heat number we can trace to the beginning of raw material import.
Carbon Steel, Alloy Steel Flanges and Stainless Steel Slip On Flanges are delivered with or without surface protection, as determined by the manufacturer.
The company delivers Nickel Alloy Flanges in standard packaging, without surface protection or end protectors (caps). Special packaging, protective covers, and end protectors (caps) can be agreed upon.
