( ) wider than the width across flats of the nut.

2 The depth of the shot shall admit the nut so that there is no interference with the joining of the Flanges when bolted together without Orifice plate. PRESSURETAPS(1) Each Orifice falnge is provided with two pressure tap holes extending radially from the outside diameter of the flange to the inside diameter of the flange . Corner taps may be used on NPS 1 1/2 and smaller if space permits. Each pressure tap hole shall be equipped with a pipe plug.(2)The in. ( ) locating dimension for raised face and in. ( ) for ring joint shall be measured at the bore.(3) Each pressure tap hole shall be equipped with a pipe plug. FACINGThe finish of Contact Faces Shall Conform to the Requirements of ASME / ANSI B FLANGETHREADS(1)Theaded Flanges shall have an American Notional Standard taper pipe thread conforming to ANSI B (2)The thread shall be concentric with the axis of the flange and variations in alignment shall not exceed in ( ) per foot.

3 (3)Theflanges are madewith counterbored at thebackoftheflangeandthethreadsshallbech amferedto thediameterof the counterbore at an angle of approximately 45 degrees with the axis of the thread to afford easy entrance in making a chamfer shall be concentric with the thread.(4) In order to permit the pipe to be inserted to the flange , the threads should have full root diameters through to the face of the flange , or shall have a counterbore at the face of the flange .(5)Thegagingnotchoftheworkinggage shallcomeflushwiththebottomofthechamgeri nallthreadedflanges and shall be considered as being the intersection of the chamger cone and the pitch cone of the depth of chamfer is approximately equal to 1/2 of the pitch of the thread.(6)The maximum allowable threa variation is one turn large or small from the gaging notch. TOLERANCEST olerances on all dimensions shall be as shown ANSI except for those shown below.

4 (1)Tolerance on location of center of pressure tap hole from flange face shall be : a. Flanges smaller than nominal size 4 in ( ) b. Flanges nominal size 4 and larger in ( )(2) Bore diameter tolerance (welding neck Flanges only) is of nominal value. #05+ $ (QTIGF (NCPIGUHH yyddrraauulliicc&&OOffffsshhoorreeSSuupp pplliieessTel: +44 (0)191 549 7335 Fax: +44 (0)191 516 0004 Email: Website: / 26 CLASS 300 Orifice FLANGESANSI B Forged (t) ofBevelLENGTH THRU HUB (T)BORE (B)Raised FaceWeldingNeckSlip-on&ThreadedWeldingNe ckSlip-onDXGAR aised FaceRaised 1 1 1 :1.
