Hauj lwm
Xiav polyethylene zaub mov hose rau cov dej haus tsis sib haum / tshuab qhua John. Usualy siv rau cov roj cua siab. Sab hauv txoj kab uas hla 6.0 hli, txoj kab uas hla 8.0 hli. Tus nqi yog siv tau rau 1 meter ntawm lub hose.
Tsis txawj:
- Sab hauv: 6.0 hli
- Txoj kab uas hla sab nraud: 8.0 hli (5/16″)
- ambient kub tsis kam: -30 ° C txog 70 ° C
- Media kub ntau: -20 ° C txog 60 ° C
- Daim Ntawv Pov Thawj: SK, NSF
Qhov siab tshaj plaws ua haujlwm siab thiab kub:
| txheej txoj kab uas hla | puab inch | Siab ntawm 20 ° C (70 ° F) | Siab ntawm 60 ° C (140 ° F) |
| 6.35 hli (1/4 ″) | 4.0 hli | 10 bar (145 PSI) | 6 bar (87 PSI) |
| 8.00 hli (5/16 ″) | 6.0 hli | 9 bar (130 PSI) | 5 bar (72 PSI) |
| 9.5 hli (3/8 ″) | 6.7 hli | 8 bar (116 PSI) | 4.5 bar (65 PSI) |
| 12.7 hli (1/2 ″) | 9.5 hli | 7 bar (102 PSI) | 4 bar (58 PSI) |
Cov yeeb nkab polyethylene yog tsim los rau kev faib cov dej haus (dej, npias, kua txiv hmab txiv ntoo, kua txiv hmab txiv ntoo, roj thiab cawv). Lawv yog ua los ntawm cov khoom siv PE ib txheej rau zaub mov, uas yog yoog tau, huv si thiab sib xws nrog DMfit thiab John Guest cov khoom sib txuas sai.
Cov yeeb nkab no sib xws nrog DMfit thiab John Guest cov khoom sib txuas ceev ntawm cov yeeb nkab.
