Stainless Steel Weld Neck Flange

We are engaged in delivering high end Weld neck flange (WNRF) which is tested for its durability and stability by our expert supervisors. The usage of this product is well defined and the product is widely used accordingly. Our Weld neck flange has a long pointed focal point hub and thus becomes easy to distinguish it. Weld-Neck flanges or welding-neck flanges are best suited for severe service conditions, whether loading conditions are substantially constant or fluctuate between wide limits.

This product is dimensionally accurate and exhibits great levels of accuracy and precision. We ensure that the product delivers maximum output and comes within the budget of our clients. Our product designers ensure that they communicate with the clients and understand the various problems faced by them. This enables our team to manufacture products that may fulfill the various technological aspects. The product is exported to places near and far which speak volumes of the technological sophistication of our product. Further on to elaborate on the technical aspect of our product. Weld neck Flanges are drilled (machined) with the wall depth of the flange having the similar 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.



Features:
  • Easy usage
  • Beneficial
  • Low maintenance

Stainless Steel Welded Flange

Suitable for petrochemical applications, the Stainless Steel Welded Flange is specially designed for sustaining severe service conditions caused due to sub-zero, high pressure or high temperature. Constructed with a long tapered hub, there is a gradual transition of thickness in the area of butt weld joining to the pipe.  Ensuring no restriction to the flow of liquid, this type of welded flange can be easily bored as to match the inner diameter of the mating pipe. This results in the reduction of erosion, thus preventing turbulence at the joint.

Features:
  • Long & tapered hub
  • Resistant to dishing
  • Can sustain high pressure & temperature load
  • Rust proof finish
  • Smooth transition from flange thickness to pipe
  • Ensure excellent stress distribution
  • Can be easily radio graphed for flaw detection
  • Can be easily welded to a pipe or fitting with a single full penetration

Technical specifications:
  • Flanges form : Stainless steel ASTM A 182, A 240
  • Flanges size : 1/8" NB TO 48"NB
  • Flanges class : 150, 300, 400, 600, 900, 1500 & 2500
  • Flanges grade : F 304, 304L, 304H, 316, 316L, 316Ti, 310, 310S, 321, 321H, 317, 347, 347H, 904L
