This is a continuous spiral groove. Flanges sizes 12” and smaller, are produced with a 1/16” round-nosed tool at a feed of 1/32” per revolution. For sizes 14” and larger, the finish is made with 1/8” round-nosed tool at a feed of 3/64” per revolution.SPIRAL SERRATED OR PHONOGRAPHIC:This finish is produced by using a 90 DegreeCelsius included-angle《V》tool, making a spiral grove 1/64” deep with a feed of 1/32”.CONCENTRIC SERRATED:This finish a produced by using a 90 Degree Celsiusincluded-angle 《V》tool, making concentric groove 1/64” deep and 1/32” apart.SMOOTH FINISH:This finish is produced by several shapes of tools cutting at speeds andfeeds which leave no definite tool marks apparent to the naked eye.1. RAISED FACE, AND LARGE MALE AND FEMALEEither a serrated-concentric or serrated-spiral finish having from 24 to 40 grooves per inch is used.The cutting tool employed has an approximate 0.06 in. or large radius. The resultant surface finish has a 500 microinch (12.5 µm) appropriate roughness.2. TONGUE AND GROOVE, AND SMALL MAKE AND FEMALEThe gasket contact surface does not exceed 125 microinch (3.2µm) roughness.3. RINGJOINTThe inside wall surface of gasket groove does not exceed 63 microinch (1.6µm) roughness.4. BLINDBlind flanges need not be faced in the center if, when this center part I raised, its diameter is atleast 1 in. smaller than the inside diameter of fittings of the corresponding pressure class. When the center part is depressed, its diameter is not greater than the inside diameter of thecorresponding pressure class fittings. Machining of the depressed center is not required.

Similarly, when the greaterthickness is provided on the inside of the flange, it shall be taper-bored from the welding end at a slopw not exceeding 1 to 3.When flanges covered by this standard are intended for services with light wall, higher strength pipe, the thickness of the hub at the bevel may be greater than that of the pipe to which the flange is joined. Under these conditions a single taper hub may be provided and the outside diameter of the hub at the base (Dimension X) may also be modified.The additional thickness may e provided on either inside or outside or partially on each side, but the total additional thickness shall not exceed one-half times the nominal wall thickness of intended mating pipe.Notes:(1) When the materials joined have equal minimum specified yield strength, there shall be no restriction onthe minimum slope. (2) Neither t 1, t 2, nor their sum (t 1+t 2) shall exceed 0.5t.(3) When the minimum specified yield strengths of the sections to be joined are unequal, the value of t Dshall at least equal t times the ratio of minimum specified yield strength of the pipe to minimum specified yield strength of the flange.W HILE EVERY EFFORT HAS BEEN M ADE, TO ENSURE THAT THE INFORMATION GIVEN ON THIS PAGE IS ACCURATE, LUDA FLANGES DOES NOT ACCEPTNotes:(1) Expect flanges with Small Male/ Female Face (on pipe end), threaded flanges, have an American National Standard taperpipe thread conforming to ANSI B2.1(2) The thread is concentric with the axis of the flange and variations in alignment do not exceed 0.06 in. per foot (0.5 percent).(3) Class 150 flanges are made without counterbore. The threads are chamfered approximately to the major diameter of thethread at the back of the flange at an angle of approximately 45 degrees with the axis of the thread. The chamfer isconcentric with the thread and included in the measurement of the thread length.(4) Class 300 and higher pressure flanges are made with a counterbore at the back of the flange. The threads are chamferedto the diameter of the counterbore at an angle of appropriately 45 degrees with the axis of the thread. The counterbore andchamfer are concentric with the thread.(5) The minimum length of effective thread in reducing flanges is at least equal to dimension Q of the corresponding class ofthreaded flange as shown in the above tables. Threads do not necessarily extend to the face to the flange.THREADWhile every effort has been made, to ensure that the information given on this page is accurate.
