Chav kawm 150 thiab 300 li 12-nti thiab me zog yog cov khoom ua ntu zus raws li qhia hauv ob daim duab. Tshwj tsis yog tias muaj lwm yam kev paub meej, hnub xaus yog dhuav kom phim sij hawm 40 yeeb nkab rau hauv cov nplaum 10-nti thiab me thiab txheem txheem cov yeeb nkab yeeb nkab (0.37 ~ tuab) hauv 12-ntom li qub.
Orders for Class 150 thiab 300 taub qab vuam tshuab 14-nti thiab loj dua. Thiab rau chav kawm 400 thiab ntau dua qub hauv txhua qhov ntau thiab tsawg, Yuav tsum qhia kom meej hauv lub taub hau ntawm cov yeeb nkab uas yuav siv cov khoom qub, thiab hom nraub qaum ris. Lwm hom kev npaj ntub kawg nkaus tuaj yeem muab luam tawm thaum teev.
Nco Ntsoov:
A = Sab Nraud (Kev Sib Hlaub Hlau Li) B = Nominal sab hauv ntawm cov yeeb nkab
C = B + 0.25t-0.041 ~ t = Nominal Yeeb Phab Thawv Ntsuas
C = B + 0.25t-0.041 ~ 0.09 = 3/32 ~ 0.75 = 3/4 ~ 0.12 = 1/8 ~ 0.88 = 7/8
0.03 = 1/32 ~ 0.16 = 5/32 ~ 0.06 = 1/16 ~ 0.38 = 3/8

Nco Ntsoov:
1. NPS 24 ~ thiab me dua los ntawm ANSI B16.5, NPS 26 thiab ntau dua los ntawm MSS SP-44.
2.Class 150 thiab Class 300 flange cov thickness thickness nrog 0.06 inch convexity.
