Weld Neck Flat Face Flanges are generally used in high pressure applications, where hot or cold temperatures exist. These steel weld neck flat face flanges are circumferentially welded into the system at its neck which means that the integrity of the butt welded area can be easily examined by radiography. These weld neck flat face flanges reduce the turbulence and erosion inside the pipeline because the bores of both pipe and flange match. This also reduces high stress concentration at the base of the hub of the weld neck flat face pipe flange. Such weld neck flat face flanges are favoured in critical applications. The inside diameter of a weld neck flat face flange is machined to match the inside diameter of the pipe. Tesco Steel & Engineering manufacture a wide range of high quality Weld Neck Flat Face Flanges in India. We offer these flanges in ASME/ANSI/DIN standards.
