For use with emulsion (fat content minimum 8%). Application: Tapered pipe threads (NPT) to ANSI B1.20.1, for threads with seala nts. See the table for the specified minimum size of the tapping hole. Recommendation: Tapping hole 0 A: Pre-drill a plain hole, do not use a reamer. Tapping hole 0 B: Pre-drill a plain hole then ream it using a 1:16 taper reamer. The taper bore 0 can then be checked laterally by reference to the Dmn check dimension (see table). Variant B for drilling the tapping hole offers the best process reliability for the tapping operation. 138100 Suitable for/ v( m/min Alu plastics vS3SL> Alu wo . cast “ 3 > 10% Si X < 500 N X < 750 N 3C < SOON X < 1100 N X <1400 N XXX <55 HRC <60 HRC <65 HRC X X IN0X <67 HRC <70 HRC < 900 N INOX >900 N Ti > 850 N Graphite GRP CRP Uni 6 i ISO code T N P H N 138100 23 13 7 NPT 138100 Machine taps HSS-E-PM TiAIN 121.28 121.28 153.95 192.06 304.92 450.45 Threads per TP inch 27 18 18 14 14 11.5 mm 90 100 100 125 140 160 mm 7 11 12 16 20 25 mm 5.5 9 9 12 16 20 U3 Tapping hole 0 Tapping hole 0 Thread gauge 0 Tapping hole mm 8.5 11 14.5 17.85 23.2 29 B mm 8.25 10.75 14.1 17.5 22.7 28.6 Dm„ + 0.05 mm 8.74 11.36 14.8 18.32 23.67 29.69 minimum depth mm 12 17.5 17.6 22.9 23 27.4 138090 187
