5.6 SLIP-ON FLANGES

Slip-on flanges, when permitted, shall be double welded and vented though thehub with a 3mm diameter pre-drilled vent hole. The flanges shall be positioned sothat the distance from the face of the flange to the pipe shall be about equal to thenominal pipe wall thickness plus 3 mm. The welds shall be applied in a mannerthat will not require re-facing of the flange.

5.7 FABRICATION TOLERANCES

PIPING CONTRACTOR is responsible for fabricated dimensions that agree withpiping drawingsand applicable codes.

Where not otherwise specified, dimensional tolerances shall conform to thoseshown in table 1

All angular dimensions of bends and branches shall be maintained within + 1degree.
