dunta BSP (British Standard pipe) dunta iyo NPT (National Pipe Thread) duntu waa laba heer oo dunta tuubbada oo caadi ah, oo leh faraqyo muhiim ah:
- Heerarka Gobolka iyo Qaranka
Dufanka BSP: Kuwani waa halbeegyo Ingiriis ah, oo ay dejisay oo ay maamusho Hay'adda Heerarka Ingiriiska (BSI). Waxay leeyihiin xagal dun ah oo ah 55 darajo iyo saamiga taper ee 1:16. Dufanka BSP ayaa si weyn looga isticmaalaa Yurub iyo wadamada Barwaaqo-sooranka, sida caadiga ah warshadaha biyaha iyo gaaska.
NPT Threads: Kuwani waa halbeegyo Mareykan ah, oo ay habeeyeen oo ay maamulaan Machadka Heerarka Qaranka Mareykanka (ANSI) iyo Bulshada Mareykanka ee Injineerada Makaanikada (ASME). Dufanka NPT waxay leeyihiin xagal dun ah oo ah 60 darajo waxayna ku yimaadaan labadaba si toos ah (cylindrical) iyo foomamka duuban. Dufanka NPT waxaa lagu yaqaanaa wax qabadkooda xirida wanaagsan waxaana badanaa loo isticmaalaa in lagu qaado dareerayaasha, gaaska, uumiga, iyo dareerayaasha haydarooliga.
- Habka xiridda
Xargaha BSP: Caadi ahaan waxay isticmaalaan weel-dhaqista ama shaabadeynta si ay u gaaraan xirid.
Xargaha NPT: Waxaa loo qaabeeyey xiridda birta-ilaa-birta, badanaa uma baahna xirmooyin dheeri ah.
- Goobaha Codsiga
Xargaha BSP: Inta badan laga isticmaalo UK, Australia, New Zealand, iyo gobollada kale.
NPT Threads: Ku badan Maraykanka iyo suuqyada la xidhiidha.
Xargaha NPT:Heerka Ameerika oo leh xagal dunta 60-degree ah, oo inta badan laga isticmaalo Waqooyiga Ameerika iyo gobollada ANSI u hoggaansan.
Taxanaha BSP:Heerka Ingiriiska oo leh xagal dunta 55-degree ah, oo sida caadiga ah laga isticmaalo Yurub iyo wadamada Barwaaqo-sooranka.
