Stainless Steel Reducing Flange

Reducing Flange

Manufacturer of ASME B16.5 Reducer Weld Neck Flange in India, We Supply Carbon Steel NPT Reducing Flanges with NDT Certificate

A reducing flange is a type of flange that connects piping equipment of dissimilar sizes in the industry. The Reducing Flange allows for a gradual drop in the size of the flange from the top to the bottom, allowing for easy installation with subsequent equipment in the system. A Reducing Pipe Flange allows easy room for cleaning and inspection due to its excellent design specification. These flanges are manufactured with concentric and eccentric specifications. The Concentric Flange is a cone-shaped adaptor that has a common center line that helps in connecting the pipe or tube section on a similar axial plane. A Stainless Steel Reducing Flange has enhanced corrosion resistance properties and is tolerant to chloride stress corrosion in harsh environments. Our institution is a Reducing Flange manufacturer in India who make use of the best raw materials and latest technology. All national and international standards are followed to manufacture the best products in the industry.

The Reducing Weld Neck Flange is designed with a raised face that provides support to different piping equipment. These flanges are welded using a butt-weld and can handle pressurized fluids and gases. A Reducing Blind Flange is produced without any boring center or hub. These flanges act as blanks that allow them to cut the flow of media in the system. The Reducing Slip On Flange is a flat disc that is slid on the surface of the pipe and welded using fillet welds. These flanges are very versatile and are available at reasonable prices. They can handle lower pressure and temperature applications. A Reducing Socket Weld Flange is used to typically join smaller sized pipes. These flanges have the same static strength as slip-on flanges but are welded using a single fillet weld. The Reducing Threaded Flange is one of the oldest and simplest methods to connect different piping equipment. These flanges have threads and don’t require any welding process to put them in place. A Reducing Companion Flange allows for quick assembly and disassembly of connected components. These flanges are either socket or threaded specifications to attach the pipe in the correct place. The Reducing Hub Flange is a device made up of a flat steel plate that is used to operate in significantly less space. These flanges are fitted with bolts, allowing room for an easy installation process. A 4x3 Reducing Flange has an aesthetical surface finish that provides them with good adhesion using the gaskets during the installation process.

ASME B16.5 Reducing Flanges Features

  • Reducing flanges are a little simpler to bolt up than non-reducing flanges.
  • They are the finest choice when you need to link flanges of various diameters.
  • There are several sizes and pressures available for these flanges.
  • Equal-sized flanges are joined with various connecting components by welding, glueing, or clamping to create reducing flanges.
  • They are the simplest and most affordable method of joining two flanges of different diameters.
