Slip On Flanges

Slip On Flanges

We offer an extensive range of Slip on Flanges, which is a very popular type of pipe flanges. These flanges slide over the end of piping and then welded in place, ie Welding Slip On Flanges. Slips on Flanges are perfect for lower pressure applications and can be easily fitted & welded into different pipes. The welding helps to reduce the fabrication costs of these pipes.


There are two types of Slip on Flanges:-

  • Slip on Flanges with Hub
  • Slip on Flanges without Hub






Flat Face Flanges

Flat Face Flanges

The flat face flange has a gasket surface in the same plane as the bolting circle face. Applications using flat face flanges are frequently those in which the mating flange or flanged fitting is made from a casting.

Flat face flanges are never to be bolted to a raised face flange. ASME B31.1 says that when connecting flat face cast iron flanges to carbon steel flanges, the raised face on the carbon steel flange must be removed, and that a full face gasket is required. This is to keep the thin, bittle cast iron flange from being sprung into the gap caused by the raised face of the carbon steel flange.





Blind Flanges

Blind Flanges

A Blind Flange has no bore, and is primarily used to close ends of piping systems. The unique design of the flange permits easy access to a line ones it has been sealed. Our range of blind flanges, steel blind flanges, stainless steel blind flanges can be machined to accept a pipe of the nominal Size to which reduction is being made. The reduction can be either threaded or welded based upon the requirements of the client.

Types of Blind Flanges:-





Weld Neck Flange

Weld Neck Flange


Welding neck flanges are distinguished from other types by their long tapered hub and gentle transition of thickness in the region of the butt weld joining them to the pipe. The long tapered hub provides an important reinforcement of the flange proper from the standpoint of strength and resistance to dishing.

 

the smooth transition from flange thickness to pipe wall thickness effected by the taper is extremely beneficial under conditions of repeated bending, caused by line expansion or other variable forces and produces an endurance strength of welding neck flanged assemblies equivalent to that of a butt welded joint between pipes, which, in practice, is the same as that of unwelded pipe.

thus this type of flange is preferred for every severe service condition, whether this results from high pressure or from sub-zero or elevated temperature, and whether loading conditions are substantially constant or fluctuate between wide limits.

Socket Weld Flanges

Socket Weld Flanges
Socket weld flange is a device that is welded to the end of pipe so that the pipe can be bolted to another pipe with a similar flange. Stainless steel socket weld flanges enable a pipe to be disconnected and reconnected with ease. Available in a spectrum of shape and sizes, our forged light weight steel socket weld flanges are manufactured using superior grade material such as stainless steel socket weld flanges, carbon steel socket weld flanges and known for their durability and performance.




Spectacle Blind Flanges

Spectacle Blind Flanges
We offer spectacle blind flanges in varied dimensions and shapes that are widely in demand in a number of industries such as
  • Petroleum(oil & gas)
  • Chemical
  • Nuclear power plant
  • Ship building
  • Pressure vessel
  • On-off shore plant




Long Weld Neck Flanges

Long Weld Neck Flanges
We offer long weld neck flanges in alloy and non-alloy materials. These alloy long weld neck flanges are offered in various diameters and sizes. Long weld neck flanges are machined with the wall thickness of the flange having the same dimensions of the matching pipe.

The lighter is the pipe, the larger will be the bore and vice verse. These flanges are equally suitable for high-pressure, cold or hot temperature applications.

Blind Ring Joint Flanges

Blind Ring Joint Flanges


Our range of stainless steel ring joint flanges is highly appreciated for strength, durability, reliability, corrosion resistance and close tolerances. These stainless steel ring joint flanges conform to various Indian and international quality standards. Used in a number of industries, these stainless steel ring joint flanges are supplied in various dimensional specifications.

For specific requirements, we also custom design ring joint flanges in preferred specifications.






Weld Neck Ring Joint Flange

Weld Neck Ring Joint Flange

Weld neck Ring Joint Flanges are designed for use in changing diameters in a piping system. A Weld neck Ring Joint Flange comprises 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. These flanges are used at the outlet side of the expansion joint to increase the size of the flange. This is considered to be an economical method to make a transition in size.

Materials used:

  • Carbon steel   
  • Stainless steel  
  • Alloy steel  
  • Brass             
  • Cast Iron          
  • Bronze      
  • Aluminum
