Hloov mus rau qhov tseeb Txoj kab uas hla mus ua nom diam
Qhov yooj yim txoj kev los mus nrhiav seb cov yeeb nkab me me uas koj xav tau yog siv los ua raws li cov theem no thiab siv daim ntawv hloov pauv hauv qab no.
Rau Txiv Neej Cov Lus{{0} Nrho. Ntsuas Cov Vauv Sab Nraud (OD) ntawm koj lub yeeb nkab lossis cov yeeb nkab siv:
{{0} Nrho. Siv daim duab ntsuas ntawm nplooj ntawv no txhawm rau txhawm rau pom lub npe me (lub taub yeeb nkab loj). |  |
Rau Poj Niam Xov Xwm{{0} Nrho. Ntsuas sab hauv txoj kab uas hla (ID) ntawm koj lub yeeb nkab lossis cov yeeb nkab haum (siv tus pas ntsuas lossis pas ntsuas). {{0} Nrho. Siv daim duab ntsuas ntawm nplooj ntawv no txhawm rau txhawm rau pom lub npe me (lub taub yeeb nkab loj). |  |

Kav vs Tubing
Cov kab yeeb thiab tub luam tsis yog ntsuas tib txoj kev.Tubing yog ntsuas thiab muaj npe raws li theactual sab nraud diameterof lub raj.
PEX, lossis Hla-Txuas Polyethylene Tubing, yog lwm qhov thev naus laus zis sai dua, thiab nws yog ntsuas thiab muaj npe los ntawm txoj kab uas hla sab hauv.
Piv txwv:
Yeeb Nkab vs. Tubing | Sab Nraum Inch |
| 1 / 2 "qhov loj qhov me | 27/32” |
| 1 / 2 "qhov loj tubing | 1/2” |
Xaiv Xov Hom
Ib qho ntawm feem ntau xov hom yogThoob Ntiaj Teb Xov Xwm (NPT).Cov no muaj nyob hauv txiv neej (NPT, MPT, lossis MNPT) thiab poj niam (FPT lossis FNPT). Cov no feem ntau muaj xov xov siv rau hauv kev sib koom ua ke thiab sib txuas cov kav dej.
Lwm cov xov yogThoob Ntiaj Teb Cov Qauv Dawb Kev Haum Ncaj Ncaj Txhua Tus Yeeb Nkab Xov (NPSM)Cov. Cov xov txuas ncaj nruab nrab no feem ntau yog siv rau kev kho tshuab pob qij txha.
BSP xov daim ntawv sawv rauBritish Txheem Yeeb. Nws yog ua raws li kev lag luam loj dua li cov taub tiag.
