Uyini Umehluko Phakathi Kwe-NPT Ne-NPSC Thread | I-PASSIONHOSE

I-NPT (National Pipe Taper) kanye ne-NPSC (National Pipe Straight Coupling) yizindinganiso ezimbili ezihlukene zezintambo zamapayipi e-United States. Umehluko omkhulu phakathi kwezintambo ze-NPT kanye ne-NPSC usekumeni kwazo kanye nezinhlelo zokusebenza ezihlosiwe.

Imicu ye-NPT iyancipha, okusho ukuthi ububanzi bentambo buyancipha kancane kancane ngasekugcineni. I-taper isiza ekudaleni ukuvala okuqinile phakathi kwemicu yesilisa neyesifazane uma iqiniswa ndawonye. Imicu ye-NPT ivame ukusetshenziswa ezinhlotsheni lapho ukuxhumana okumelana nokuvuza kubalulekile, njengepayipi, izinhlelo ze-hydraulic, kanye nemigqa yegesi.

Ngakolunye uhlangothi, imicu ye-NPSC iyimicu eqondile, okusho ukuthi ububanzi buhlala bufana nobude bentambo. Ngokungafani nemicu ye-NPT, imicu ye-NPSC ayinikezi umsebenzi wokuvala wodwa. Ngokuvamile idinga ukusetshenziswa kwezindlela ezengeziwe zokuvala njenge-thread sealant, i-tape, noma ama-gasket ukuvimbela ukuvuza. Imicu ye-NPSC ivame ukusetshenziswa ezisetshenziswayo lapho ukuvala okuqinile kungadingeki, njengezingxenye zesakhiwo noma izinhlangano zemishini.

Ngakho-ke, umehluko omkhulu phakathi kwezintambo ze-NPT ne-NPSC yile:

1. Isimo: Imicu ye-NPT inciphile, kuyilapho imicu ye-NPSC iqondile.

2. Ukuvala: Imicu ye-NPT inikeza umsebenzi wokuvala ngenxa ye-taper yayo, kanti imicu ye-NPSC idinga izindlela ezengeziwe zokuvala.

3. Izicelo: Izintambo ze-NPT zisetshenziswa ezinhlelweni zokusebenza ezidinga ukuxhumeka okumelana nokuvuza, kuyilapho izintambo ze-NPSC zisetshenziswa ezinhlelweni zokusebenza lapho ukuvala kungabalulekile noma lapho kungasetshenziswa khona ezinye izindlela zokuvala.

4. Kubalulekile ukuqaphela ukuthi lezi zindinganiso ziqondene ngqo ne-United States, futhi amanye amazwe angase abe nezindinganiso zemicu ehlukene.
