AWWA C207-07 ASTM A182 SS 316L Çelik Halkalı Flanş 48″ Sınıf F (300 psi)

Tip: Steel-Ring Flange
Material: F316L (UNS S31603)
Size: DN1200 （48″）
Standard: AWWA C207
Ends: Flat Face

AWWA Flange Standards differ from ANSI (American National Standards Institute) and ASME (American Society of Mechanical Engineers) certifications in a variety of ways, the most important being their specificity: AWWA standards evaluate properties that particularly affect potable water use, as opposed to broader industrial flange applications. American Water Works Association (AWWA) is an international non-profit, scientific and educational association founded to improve water quality and supply. Established in 1881, it has a membership (as of 2012) of around 50,000 members worldwide.

Notlar:
1. The inner diameter of the Ring type flanges can be increased or chamfered to accommodate the outer diameter of the pipe that exceeds the nominal value.
2. Metric Conversion:
  Nominal Pipe Size [in] x 25 = [mm]
  Dimensions [in] x 25.4 = [mm]
  Pressure [psi] x 6,895 = [kPa]
