BSP (British Standard Pipe) shinda uye NPT (National Pipe Thread) shinda mbiri dzakajairika pombi shinda, ine mimwe misiyano yakakosha:
- Dunhu uye National Standards
BSP Threads: Aya ndiwo mazinga eBritish, akagadzirwa uye anotungamirirwa neBritish Standards Institution (BSI). Vane tambo angle ye55 degrees uye taper reshiyo ye1:16. BSP tambo dzinoshandiswa zvakanyanya muEurope uye Commonwealth nyika, kazhinji mumaindasitiri emvura uye gasi.
NPT Threads: Aya ndiwo maAmerican standards, akagadzirwa uye anotungamirwa neAmerican National Standards Institute (ANSI) uye American Society of Mechanical Engineers (ASME). Tambo dzeNPT dzine tambo yekona ye60 madhigirii uye dzinouya mune zvese zvakatwasuka (cylindrical) uye tapered mafomu. Tambo dzeNPT dzinozivikanwa nekuita kwayo kwekuvhara kwakanaka uye dzinowanzo shandiswa kutakura zvinwiwa, magasi, chiutsi, uye hydraulic fluid.
- Kuisa Chisimbiso
BSP Threads: Ivo vanowanzo shandisa washer kana sealant kuwana chisimbiso.
NPT Threads: Yakagadzirirwa simbi-kune-simbi yekuisa chisimbiso, kazhinji haidi yakawedzera chisimbiso.
- Nzvimbo dzekushandisa
BSP Threads: Inowanzo shandiswa muUK, Australia, New Zealand, uye mamwe matunhu.
NPT Threads: Zvakawanda zvakajairika muUnited States uye misika ine hukama.
NPT Threads:Chiyero cheAmerica chine 60-degree thread angle, inowanzoshandiswa muNorth America uye ANSI-inoenderana nematunhu.
BSP Threads:Chiyero cheBritish chine 55-degree thread angle, chinowanzo shandiswa muEurope nenyika dzeCommonwealth.
