Weld Neck Flanges

This steel weld neck flanges is circumferentially 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 favoured in critical applications. The various types of steel weld neck flanges are:

• Weld Neck Flat Face Flanges
• --Raised Face Weld Neck Flanges
• Stainless Steel
