Note: You can make more or less holes on the round flange as needed. Flanges can also be made without holes.

 

Production

Strip flanges are obtained by cold rolling the strip through the rolls of the machine. The flange may consist of a single piece of strip, or of halves, or of several parts. All parts of the flange are securely welded together. Flanges with a diameter of 225 mm or more are made in the following way: the corner is cold rolled between the rollers of the machine. Next, the ends of the corner are fastened by welding.

Using a punching machine, oval holes are made on the flange (along the circumference). The finished flange is covered with primer.

Flanging

The process of attaching a flange to a duct or fitting is called flanging. The quality of a flanged product depends on the reliability of the connection between the product and the flange. To flange a round part, a ridge is made along its diameter at a distance of 15-20 mm from the edge. The flange is put on the product in such a way that it rests on the ridge. The metal emerging from the top of the flange is tapped in a circle, thus firmly pressing the flange.

Installation

Round flanged products are connected to each other using a bolted connection. The flanges of the products are aligned so that the holes match. Next, fix the connection with a bolt and nut. It is recommended to use sealant between flanges.
