Duplex Steel Weld Neck Flanges Supplier

Weld Neck Flanges:

A weld neck flange is a type of flange. There are two designs. The normal type is used with pipes. The long type is not suitable for pipes and is used in a process plant. Weld Neck Flanges are easy to recognize at the long tapered hub, which goes gradually over to the wall thickness from a pipe or fitting. The long tapered hub provides significant reinforcement for use in a variety of applications involving high pressure and high and low temperatures.

Characteristics of our Duplex Weld Neck Flanges:

Duplex Weld Neck Flanges are excellent resists corrosion in brackish and marine water. Duplex flanges are prevents stress corrosion cracking and localized corrosion in oxidizing and reducing environments. Duplex Flanges are commonly used in acid treatment tubes, pipes, parts, oil distillation plants, bleach washers, high chloride, and marine water applications. Duplex flanges are not suitable where the temperature is above 300 degrees C. Molybdenum, and chromium content shows strength and increases pitting and consistent stress corrosion cracking resistance.

These flanges are high strength and ease of handling. On this alloy, heat treatment is done, due to this treatment improve hardness, toughness strength, and ductility of duplex weld neck flanges. These alloys have better heat conductivity and lower thermal expansion.
