What is Nickel Flange?
The Nickel Slip-on Flange is well suited to low-pressure as well as temperature applications, with the flange placed on the pipe and fillet and then welded on the inside and outside. High-nickel-alloy slip-on flange is made in a way that it possesses a hole on itself with an identical outside diameter of pipe through which a pipe can pass.
