Hastelloy Slip On Flanges Manufacturer and Supplier in India

Hastelloy slip-on flanges are a kind of flanges made from Hastelloy alloys, which are known for their remarkable corrosion resistance properties. Slip-on flanges are potrayed by a slightly larger inner diameter than the outer diameter of the pipe they are connected to, allowing the pipe to slide into the flange. Hastelloy slip-on flanges are circular flanges with a bore that is slightly larger than the outer diameter of the pipe. They have a raised face on the interior, which provides a sealing surface when the flange is bolted to a matching flange or piece of machinery. These flanges commonly have a fillet weld on the interior and exterior to fasten them to the pipe and provide structural strength and support. High corrosion resistance, high strength and cost-effectiveness are some of the benefits of these slip on flanges. The applications where Hastelloy slip on flanges come into use are oil and gas exploration, pollution control, chemical processing, food and beverage processing, and many others.
