"T" must be at least - 1.25 times pipe wall thickness
for full pressure rating.
One bolt length is used for each pipe diameter for all DR's.
"T" is constant using DR 11 (or lowest available DR
by size)
The face diameter fits inside bolt-circle to promote alignment
and concentricity, with sealing.
"H" must be long enough to allow butt-fusion in all
applicable fusion machines, size on size or larger. Consult fusion
machine manufacturers for their required minimum length.
"R" must be matched to the radius of the metal back-up
ring.
Corrosion protected convoluted Ductile-Iron back-up rings are
recommended.
OD dimensions and tolerances machined in compliance with specifications
of ASTM F714.
Flange adaptor wall thickness is 10% thicker than pipe to accommodate
pipe end toe-in and out-of-roundness, while assuring virtually
100% butt-fusion contact.
Flange adaptors may be fused to same DR and to one standard
DR higher (i.e., DR17 to DR21)
