Hastelloy C276 Flanges

ASTM B564 UNS N10276 Slip on Flange and Nickel Alloy C276 Blind Flange Manufacturer in India

Hastelloy C276 Flanges

Hastelloy C276 Flange comprises of nickel, chromium, molybdenum alloy. The other elements of this alloy are carbon, manganese, sulfur, cobalt, iron, phosphorous, and silicon. These flanges have a high melting point thereby, allowing them to work in extreme temperatures. Apart from this, the flanges are extremely corrosion resistant and have considerable tensile and yield strength. These flanges are widely used in pharmaceutical, petrochemical industries, heat exchangers and various applications in marine industries. Over the last decade, we have been the leading Hastelloy C276 Flanges manufacturers in India. We ensure that the products we produce are top quality and available at reasonable rates to all.

The ASTM B564 UNS N10276 Slip on Flanges are the most popular and cost-effective flanges. These flanges are slid on seamless pipes and attached at the right location. The Nickel C276 Blind Flange is used to close pipelines either permanently or temporarily. The flanges allow you to clean and maintain the piping system if they are not welded onto the pipe. The Hastelloy C276 Weld Neck Flange is the first choice fitting for heavy-duty applications. It is made of a distinct hub, which provides support to other piping systems. This flange is fitted by butt-welding it onto the pipe. All our products are produced, using the latest technology and the best raw materials.

The ASTM B564 UNS N10276 Forged Flanges are manufactured via a forging process making, them stronger. The single-piece used to make these flanges provides support to various other materials in the piping system. We also produce the Hastelloy 2.4819 Plate Flanges that can be customized into different shapes and sizes as per your requirements. To know more about our flanges contact us.
