Stainless Steel Flanges

Welding Neck (WN, WNRF, WNRTJ) Flanges are used for high-pressure applications to reduce the concentration of stress, this type of flange has a neck that is welded to the base of pipes. One of the most popular options for high-pressure systems, the tapered hub offers strength and flexibility.
These flanges are easy to recognize at the long tapered hub, that goes gradually over to the wall thickness from a pipe or fitting.
The long tapered hub provides an important reinforcement for use in several applications involving high pressure, sub-zero and / or elevated temperatures.
We can provide Welding Neck (WN, WNRF, WNRTJ) flanges of size ½ inch to 60 inch (DN15 to DN2000) with nominal pressure rating(NPS) of ANSI Class 150, 300, 600, 1500, 2500, DIN N6, PN10, PN16,P N25, PN40, PN64, PN100, PN160 & surface treatment of Anti-rust Oil, Transparent/Yellow/Black Anti-rust Paint, Zinc, Hot dipped Galvanized with export packing done with No Fumigate or Fumigate Plywood/Wood Pallet or Case and is used in applications of Oil Field, Offshore, Water System, Shipbuilding, Natural Gas, Electric Power, Pipe Projects etc.
