NEHA METAL AND ALLOYS is a Professional steel flanges and forgings manufacturer in India, specialize in manufacturing steel valve, flanges bolts, steel flanges, steel forgings range of flange and forging types and sizes

Weld Neck Flanges (WNRF 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 high-pressure, cold or hot temperature
Tube OD sizes: 3/8 to 36 inches
Uses of weld neck flanges (WNRF FLANGES):

• The weld neck flange (WNRF FLANGES) is very resistant to dishing and has a very sturdy connection because it has the pipe along with the tapered hub.The flanges are ideal for extreme fluctuations of temperature.

• They are ideal in environments where there may be a lot of bending and handling of the flanges.
• Preferred in an environment with extreme temperature conditions.
• This type of flange is preferred for every severe service condition - resulting from high pressure or from sub-zero or elevated temperature.
• They are used in situations where loading conditions are substantially constant or fluctuate between wide limits.This is probably the best welding flange available because of its high, heavy neck.
• Highly recommended wherever a sound welded joint connection is needed.

Stainless Steel Socket Weld Flanges

Stainless Steel Socket Weld Flanges

Approx. Rs 250 / Kilogram

The Socket Welding Flanges offered by us have counter bore, which is slightly larger than the outer diameter of the matching pipe, allowing the pipe to be inserted. A restriction is built into the bottom of the bore, which acts as a shoulder for the pipe to rest on, and has the same id of matching pipe. The innovative design of flanges ensures that flow is not restricted in any direction. We offer socket welding flanges, steel welding flanges, stainless steel welding flanges in variety of specifications for application in different industries.


Socket Weld Flange
Socket welding flange, a popular type of pipe flange, was initially developed for use on small-sized high- pressure piping. The fabrication of this type of flange is similar to that of a slip-on flange. However, the internal pocket of a socket weld flange allows for a smooth bore and better fluid flow. When provided with an internal weld, the static strength of this flange is equal to slip-on flange, but the fatigue strength is 50% greater than double welding slip-on flanges. Smooth bore conditions in such a flange can easily be attained without having to bevel the flange face and, after welding, to reface the socket weld flange as would be required with slip-on flanges. For this reason, the internally welded flange is popular in chemical process piping.

Materials used:
  • Alloy steel
  • Carbon steel
  • Stainless steel
  • Cast iron
  • Rubber
  • PVC
  • Thermoplastics
  • Aluminum
  • Brass
  • Bronze etc.
Key Features:The recess on the inside diameter of the socket weld flange allows for a good fit of the pipe allowing for a smooth flow of liquid.
Socket welding flanges work well for smaller sizes and higher pressure temperature conditions. They are similar to slip-on flanges, but must specify the schedule of the pipe where they will be used for with socket welds.
