AWWA C207-18 STEEL PIPE FLANGES FOR WATERWORKS SERVICE—SIZES 4 IN. THROUGH 144 IN. (100 MM THROUGH 3,600 MM)

The AWWA C207  is an American National Standard for steel pipe flanges for waterworks service, sizes 4″ through 144″ (100 mm through 3600 mm). The AWWA is the abbreviation of “American Water Works Association”. The origin of AWWA C207 can be dated back to year 1942 when a paper proposing standards for slip-on steel-ring flanges for welding to steel water pipes. This standard was necessary because the lowest pressure ratings for steel flanges at that time were those having cold-water pressure ratings of 275 psi (1896 KPa). The ratings are far higher than those ordinarily needed for water service (150 psi / 1034 KPa) primary pressure rating.
