Notes:

A) Dimensions are shown in inches (millimeters). For bolts and bolt holes, dimensions are in inches.

B) Welding neck flanges NPS 3 and smaller are dimensionally identical to Class 600 flanges and may be so marked.

C) All other dimensions are in accordance with ASME B16.5.

D) Other NPT sizes may be furnished if required.

E) For slip-on and threaded flanges, verify that TT drilling extends to inside diameter of pipe after assembly and is free from burrs.

F) Bolt lengths include allowance for orifice and gasket thickness of 6 mm (0.25 in.) for NPS 1 to NPS 12 and 10 mm (0.38 in.) for NPS 14 to NPS 24.

G) In conformance with ASME B16.5, stud bolt lengths do not include point heights.
