SAE 4340 Slip On Flange, UNS G43400 Blind Flange Exporter

Metalfed Engineering is a leading supplier, exporter, and manufacturers of a wide range of Flanges. These Flanges are available in different types such as Slip-on Flanges, Orifice Flanges, Blind Flanges, Socket Weld Flanges, Weld Neck Flanges, Ring Type Joint flanges, and more. A flange is a method of connecting pipes, valves, pumps, and other equipment to form a piping system. It also provides easy access for cleaning, inspection, or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal. In addition, flanges, like fittings and pipes, for specific purposes sometimes internally equipped with layers of materials of completely different quality as the flanges themselves, which are “lined flanges”.

Metal flanges are commonly used for industrial, commercial, and institutional application. Steel pipe flanges are available in variety of styles and pressure classes. Metal flanges are classified from 150 to 2500 # rating. In addition to specifying pressure class, certain flanges such as weld neck flange & socket weld flange also require specifying the pipe schedule. This ensures the pipe bore will match the bore of the weld neck or socket weld flange.
