This welding 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. Weld Neck Flanges are a very common type of pipe flanges used in various industrial applications. They have a long tapered hub and are often used for high pressure applications.
Weld neck flanges are drilled (machined) with the wall thickness of the flange having the same dimensions of the matching pipe. The lighter the pipe is, the larger the bore, conversely, the heavier the pipe, the small the bore. Our range weld neck flanges, welding neck flanges are normally used for high-pressure, cold or hot temperature. We specialize these flanges in different dimensional and material specifications based upon the requirements of the clients. Highly resistant to corrosion and abrasion, our weld neck flanges, is available in different grades of material. In order to ensure quality, we follow international standards of quality and safety to manufacture these flanges. Use of qualitative material provides them spectacular durability and excellent strength. Our collection of flanges is resistant to corrosion and are available in different dimensions and configurations to suit the need of our esteemed clients.
