Flanges
Flanges
Industrial ansi flanges for saleare a part used for connections between the ends of tubes or used at the entrance and exit of equipment for connections between two devices. A flange connection is a detachable connection connected by a combination of flanges, gaskets, and bolts as a set of combined sealing structures. Flange on saleshave holes in its eyes, and the bolts keep the two flanges close together. The flanges are sealed with a gasket and flanges are used in pairs. Different flange types' thickness varies from different pressure, and the bolts used are different accordingly. Pumps and valves, when connected to pipes, are also made into corresponding flange shapes at connection parts. As one of the professional flange manufacturersand flange suppliers, we provide high-quality and different types of flangesfor sale.

Flanges Manufacturing Process
Casting
The blank size of a casting flange is accurate, so it enjoys little processing volume. The advantage of castings is that they can produce more complex shapes and have a lower cost. But casting flange types have more casting defects (pores, crack), the internal organizational structure of the casting flanges is worse.
Forging
Let's take a look at the production process for forging flanges:
The forging process is generally composed of the selection of high-quality billet material, heating, forging, cooling. Forging methods include free forging, mold forging. When producing, forging methods are selected according to the size and the number of flanges to be produced.
The advantage of forged flanges for sale is that the internal organization structure is uniform, and there are no pores, impurities, and other harmful defects;
Forged flanges can withstand higher shear and tensile forces than casting flanges.
The disadvantage is that forged flanges cost much more than casting flanges.
Cut Flanges
This method is to directly cut out the outer diameter of the flanges on the steel plate with suitable thickness, and then process the bolt holes and water lines. The maximum diameter of such flanges is limited to the width of the steel plate. The advantage of this method is low cost and the disadvantage is that only plate/blind flanges can be made by this method.
