Nominal pipe sizes over NPS 20“
up to NPS 1000“ on request.
L = Total length
d1 = Outer diameter of the elbow
d4 = Raised face diameter
K = Bolt circle diameter
smin = Minimum flare thickness
a1 = Minimum length with fixed flange and smin
a2 = Minimum length with loose flange and smin
Technical data valid for the pressure rating Class 150.
a1 and a2 depend on construction type and lining thickness.
