Weld Neck Flanges are drilled(machined) with the wall thickness of the flange having the same dimensions of the matching pipe, the lighter the pipe is, the larger the bore, conversely, the heavier the pipe, the small the bore, they are normally used for highpressure, cold or hot temperature.

This flange is circumferentially welded into the system at its neck which means that the integrity of the butt welded area can be easily examined by radiography. The bores of both pipe and flange match, which reduces turbulence and erosion inside the pipeline. The weld neck is therefore favoured in critical applications.
The various types of weld neck flanges are:

  • Weld Neck Flat Face Flanges
  • Raised Face Weld Neck Flanges


We manufacture and export a wide assortment of flanges that are available in all sizes, pressure ratings and in all the common configurations. Our range comprises of weld neck flanges, slip on flanges, blind flanges, lap joint flanges, threaded flanges, din flanges, socket weld flanges and more. Fabricated using best grade raw material, these are known for their dimensional accuracy, high strength and durability. Further, our range comply with various national and international standards.

These are available in all types and pressures and are widely used for pipe-to-pipe connections. The reducing flange includes a flange with one specified diameter having a bore of a different and smaller diameter. Except for the bore and hub dimensions, the reducing flange will have dimensions of the larger pipe size. To increase the size of the flange, these are used at the outlet side of the expansion joint. It is the most economical method to make a transition in size.
