Alloy Steel Weld Neck Flanges

We are offering alloy steel weld neck flanges. This alloy steel weld neck flanges is circumferential welded into the system at its neck which means that the integrity of the butt welded area can be easily examined by radiography. The bores of both pipe and flange match, which reduces turbulence and erosion inside the pipeline. The weld neck is therefore favored in critical applications.
