Uyini Umehluko Phakathi Kwe-NPT Ne-NPTF Thread?

NPTkanye nezintambo ze-NPTF zombili ziyizindinganiso zentambo yepayipi enciphile esetshenziselwa ukudala ukuxhumana okuvimbela ukuvuza, kodwa ziyahlukahluka ngendlela yazo yokuvala:

I-NPT ( I-National Pipe Taper ): Lena intambo yenhloso ejwayelekile encike ku-sealant, njenge-Teflon tape noma i-pipe dope, ukuze kufezwe uphawu olungavuzi. Izintambo ngokwazo zakha i-joint eqinile, kodwa i-sealant igcwalisa noma yiziphi izikhala ezincane kakhulu futhi ivimbele ukuvuza.

I-NPTF ( i-National Pipe Taper Fuel ): Lena intambo ye-dryseal, eyenzelwe ukwakha uphawu lomshini ngaphandle kokudinga noma yisiphi isivalo esengeziwe. Umehluko omkhulu usempandeni kanye ne-crest yentambo. Izintambo ze-NPTF zinezimbobo ezibukhali kancane kanye nezimpande ezisicaba uma kuqhathaniswa ne-NPT. Uma ziqinisiwe, lokhu kuguquguquka kudala uphawu lwensimbi nensimbi ukuze kube nokuxhumana okuqinile okuvikela ukuvuza. Izintambo ze-NPTF zihlukaniswa ngezigaba ezimbili:

Isigaba 1: Sinikeza isivalo esiqinile sokucindezela okuphezulu.

Isigaba 2: Sihlinzeka ngokulinganisela okuhle phakathi kwamandla esivalo kanye nokulula kokuhlanganiswa/ukuhlukaniswa.

Nasi ukuqhathanisa okusheshayo:

Ngamafuphi, sebenzisa i-NPT ekusetshenzisweni okuvamile lapho ukuvala okuhle okune-sealant kwanele. Khetha i-NPTF ezimweni ezinomfutho ophezulu, ezishisa kakhulu, noma lapho ufuna ukugwema ukungcola kwe-sealant.
