Odelya International Steel

Welding Neck Flanges

Odelya® Welding Neck Flanges have a long tapered hub or neck, which is gradually connect the flange with the pipeline or fitting, providing the same wall thickness in the butt welding area. Moreover, due to smooth transition of wall thickness from the neck base to the pipe or fitting, the weld neck flanges are provided with important reinforcement, matching bore of the mating line pipe as well.

Odelya® Welding Neck (WN) Flanges are used in high stress applications involving sub-zero or elevated temperatures and high pressure, as the neck or hub provides stress distribution of the piping system and excellent strong connection. Additionally, design of Odelya® WN Flanges provides reduction of corrosion, turbulence at joints and welding area can be easily examinated by radiography.
