Weld neck flanges excel in high-pressure/temperature pipelines. The weld neck flange’s tapered hub reduces stress in oil/gas systems. Full-penetration welds make weld neck flanges leak-proof for PN16-PN420 ratings.
RTJ/grooved-face weld neck flanges (ASME B16.5) suit sour service (NACE MR0175). Long-neck weld neck flanges minimize turbulence in cryogenic applications. All weld neck flanges include PMI test reports.
