Txiav threads: standard tolerances
Tapped qhov yuav tsum tau tshwj xeeb diameters, qhov tob, thiab cov cua ntsawj ntshab kom ntseeg tau tias cov khoom siv tau zoo.Draft tuaj yeem khaws cia, raws li kev tso cai 85% tag nrho xov qhov tob ntawm qhov kawg me me thiab 55% ntawm qhov kawg loj.Peb pom zoo kom siv lub txee lossis lub vojvoog los muab kev pabcuam rau cov khoom siv uas tau hloov pauv thiab ntxiv dag zog rau cov tub ntxhais hauv lub cuab yeej.
Txiav threads: tseem ceeb tolerances
Qhov loj dua qhov tseeb yog ua tau ntawm qhov tapping, tab sis nws los ntawm tus nqi siab dua.Draft tuaj yeem khaws cia, raws li kev tso cai 95% tag nrho xov qhov tob ntawm qhov kawg me me thiab qhov siab tshaj plaws me kab ntawm qhov loj kawg.
Tsim threads: tseem ceeb tolerances
Tag nrho cov tsim threads xav tau ntau dua qhov tseeb teev nyob rau hauv cov kev kam rau siab tseem ceeb.Cored qhov yuav raug tapping yam tsis tau tshem tawm cov cua ntsawj ntshab.
Cov yeeb nkab threads: standard tolerances
Cored qhov yog tsim rau NPT thiab ANPT.NPT yuav tsum tau teev nyob qhov twg ua tau, vim yog cov nqi ntxiv thiab cov kauj ruam yuav tsum tau ua.Lub 1 ° 47 'taper ib sab yog qhov tseem ceeb rau ANPT dua li NPT.
Tsis muaj cov qauv rau metric yeeb nkab threads.
