PN 63 EN 1092-1 Type 11 Weld Neck Flanges are generally used in high pressure applications, where hot or cold temperatures exist. These steel PN 63 EN 1092-1 Type 11 weld neck 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 pn 63 type 11 weld neck 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 PN EN 1092-1 weld neck pipe flange. Such weld neck are favoured in critical applications. The inside diameter of a #63 Type 11 weld neck flange is machined to match the inside diameter of the pipe. Tesco Steel & Engineering manufacture a wide range of high quality PN 63 EN 1092-1 Type 11 Weld Neck Flanges in India.
