BSP (British Standard Pipe) imisonto kunye NPT (National Pipe Thread) imisonto yimigangatho emibini eqhelekileyo yombhobho, kunye nolunye umahluko ongundoqo:
- ImiGangatho yoMmandla neyeSizwe
Imisonto ye-BSP: Le yimigangatho yaseBritani, equlunqwe kwaye ilawulwa yiBritish Standards Institution (BSI).Bane-angle yentambo yee-degrees ezingama-55 kunye ne-taper ratio ye-1:16.Imisonto ye-BSP isetyenziswa kakhulu kumazwe aseYurophu nakwi-Commonwealth, ngokuqhelekileyo kumashishini amanzi kunye negesi.
Imisonto ye-NPT: Le yimigangatho yaseMelika, yenziwe kwaye ilawulwa yi-American National Standards Institute (ANSI) kunye ne-American Society of Mechanical Engineers (ASME).Imisonto ye-NPT ine-angle yentambo yee-degrees ezingama-60 kwaye iza kuzo zombini ezithe tye (i-cylindrical) kunye neefom ezithathiweyo.Imisonto ye-NPT iyaziwa ngokutywinwa kwayo kakuhle kwaye iqhele ukusetyenziselwa ukuthutha ulwelo, iigesi, umphunga, kunye nolwelo olusebenza ngolwelo.
- Indlela yokutywina
Imisonto ye-BSP: Ngokuqhelekileyo basebenzisa iiwasha okanye i-sealant ukufezekisa ukutywinwa.
Imisonto ye-NPT: Yenzelwe ukutywinwa kwentsimbi ukuya kwintsimbi, kaninzi ayifuni isitywina esongezelelweyo.
- IiNdawo zokuSebenza
Imisonto ye-BSP: Isetyenziswa ngokuqhelekileyo e-UK, e-Australia, eNew Zealand nakweminye imimandla.
Imisonto ye-NPT: Ixhaphake kakhulu e-United States nakwiimarike ezinxulumeneyo.
Imisonto ye-NPT:Umgangatho waseMelika kunye ne-60-degree thread angle, esetyenziswa ngokuqhelekileyo eMntla Melika kunye nemimandla ehambelana ne-ANSI.
Imisonto ye-BSP:Umgangatho waseBritani one-angle ye-55-degree thread, esetyenziswa ngokuqhelekileyo eYurophu nakwi-Commonwealth kumazwe.
