When furnished with raised face or flat face, Futawa's USAS flanges may have any type of the gasket surface finishes. Unless
otherwisespeclfled by the purchaser, theSPIRAL SERRATED FINISH will be furnished.

SPIRAL SERRATED FINISH:

is a continuous spiral groove. The groove is 0.001" to 0.006" deep and is 20 t o 50 per inch.

IFINISH FINISH

The following details should be noted:
a) Ciasket surface is always square with axis of pipe.
b) Bolt holes are multiple-drilled with extreme accuracy.
c) Spot facing or back facing is not done, if the back of flange is parallel to the flange face within 1 degree.
d) The fillet radius at base of hub is designed to provide enough clearance so that socket wrenches can be used.

3) INSPECTION:
After machln~ng,finished flanges are individually checked as to all details, and mlll's Inspection certlf~cateshall submit you
upon request I f necessary, independent inspector's inspect~oncan be applied at purchaser's account.

4) Marking:

Each flange is either run through a marking machine or hand stamped along the outside diameter for complete and permanent

identification. The stamping is done for the pressure rating, the nominal pipe size, the material specification and the

trademark of FUTAWA. . -.-s ,

5) Cleaning and coating:
Finished flanges are washed thoroughly with thinner then dipped in synthetic enamel.

METHODS OF ATTACHMENT Although recommended practice in attaching Slip-on type flanges is to weld
both at the flange hub and the pipe end, for mild service conditions only one is
sometimes employed. In this case the weld is normally made at the pipe end.

METHODS OF ATTACHMENT

Lap Joint Flanges are most frequently,used with lap Joint Stub Ends, although
in some cases the lap is formed on the pipe end. Since they are free to rotate or
swivel there is no problem of bolt hole alignment. Such joints may be readily
broken for inspection, cleaning, etc. The radius at the ID of the flange face
accommodates that at the back of the lap, thus permitting more uniform
applicationof loading.

In attaching Socket Welding Flanges, the pipe end is inserted into the socket and
then welded at the flange hub. An inside weld at the pipe frequently made for
greater strength or, with grinding, to provide a smooth bore without pockets or
