Imicu ye-BSP (British Standard Pipe) kanye nemicu ye-NPT (National Pipe Thread) ingamazinga amabili avamile wentambo yamapayipi, anomehluko obalulekile:
- Amazinga Wesifunda kanye Nakazwelonke
Imicu ye-BSP: Lawa amazinga e-British, akhiwe futhi aphethwe yi-British Standards Institution (BSI).Zine-angle yentambo engu-55 degrees kanye ne-taper ratio engu-1:16.Izintambo ze-BSP zisetshenziswa kakhulu emazweni aseYurophu nasemazweni e-Commonwealth, ngokuvamile ezimbonini zamanzi negesi.
Imiluko ye-NPT: Lawa amazinga aseMelika, akhiwe futhi alawulwa yi-American National Standards Institute (ANSI) kanye ne-American Society of Mechanical Engineers (ASME).Imicu ye-NPT ine-engeli yentambo engu-60 degrees futhi ifika ngazo zombili izinhlobo eziqondile (cylindrical) kanye namafomu aqoshiwe.Imicu ye-NPT yaziwa ngokuvala kahle kwayo futhi ijwayele ukusetshenziselwa ukuthutha uketshezi, amagesi, isitimu, noketshezi olunamanzi.
- Indlela Yokufaka uphawu
Izintambo ze-BSP: Ngokuvamile zisebenzisa amawasha noma ama-sealant ukuze bathole uphawu.
Imicu ye-NPT: Idizayinelwe ukuvala uphawu kwensimbi kuya kwensimbi, ngokuvamile ayidingi isitywini esingeziwe.
- Izindawo Zokufaka Isicelo
Imicu ye-BSP: Ivamise ukusetshenziswa e-UK, Australia, New Zealand, nakwezinye izifunda.
Imiluko ye-NPT: Okuvame kakhulu e-United States nezimakethe ezihlobene.
Imicu ye-NPT:Izinga laseMelika eline-engeli yentambo engu-60-degree, evame ukusetshenziswa eNyakatho Melika nasezifundeni ezithobela i-ANSI.
Imicu ye-BSP:Izinga laseBrithani eline-angle yentambo engu-55-degree, ngokuvamile esetshenziswa eYurophu nasemazweni e-Commonwealth.
