1. ** Rau 10217-7} cov khoom siv: **
En 10217-7 Tshaj tawm cov tseev kom muaj rau ** welded stainless tus hlau ti ** rau lub siab lub hom phiaj. Cov ntaub ntawv them tau yog ** Austenitic ** thiab ** Austenitic-Ferritic-ferritic (duplex) stainless hlau **. Cov qib kawm muaj suav nrog 1.4301 (304), 1.440 (3120), 1.4462 (2205)
2. ** Qhov loj me ntawm en 10217-2 yeeb nkab: **
En 10217-2 Cov Npog} Cov Npe * Welded Tsis-Alloy thiab Alloy Steel Leeg Nrog Cov Khoom Kub Thiab Kub Thiab .. Qhov ntau thiab tsawg txhais tau los ntawm ** sab nraum lub qhov taub (OD) ** thiab ** Phab ntsa tuab **, yoog raws li ** EN 10216 series 4 tus qauv seem. Cov tau muaj ntau haiv yog ** 21.3 hli rau 1219 hli ** (DN 15 rau DN 1200). Qhov loj me nyob ntawm cov kev tsim lub raj (piv txwv li, txoj kab uas hla \/ thickness sib xyaw).
3. 4 Qhov sib txawv ntawm HDPE thiab Hlau Yeeb: **
| ** Khoom **|** HDPE YEEB **|** steel yeeb nkab ** |
| ** cov khoom siv **|High-ceev polyethylene (thermoplastic)|Carbon \/ Alloy \/ Hlau Stainless (Nws Yog Xim Hlau) |
| ** Corrosion Kuj **|Zoo heev (immune rau electrochemical corrosion)|Nquag mus rau xeb \/ tshuaj corrosion (xav kom cov txheej txheej) |
| ** Luj npluav **|Lub teeb yuag (tuab ~ ~ 0. 95 g \/ cm³)|Hnyav (ntom ~ 7.85 g \/ cm³) |
| ** Plaab **|Hloov tau; Fusion-welded pob qij txha|Tsis yeem; Threaded \/ Welded \/ Flanged Joints |
| ** Max. Thaum txias **|Feem ntau tsawg dua li lossis sib npaug rau 60 degree (140 degree f)|Tau tshaj 500 degree (932 Qib F) |
| ** Siab ntsuam xyuas **|Txo (haum rau nruab nrab \/ tsis tshua muaj siab)|Siab dua (leeg cov tshuab siab siab) |
| ** Cov ntawv thov **|Dej \/ Roj faib tawm, pleev xim|Roj \/ roj, siab-temp \/ siab, qauv |
4. ** Phab ntsa tuab ntawm en 10217-1}: **
En 10217-1 Cov Npog} Cov Npe Tsis yog-alloy steel leeg nrog chav tsev teev cov khoom kub **. Phab ntsa tuab yog ** tsis yog tus nqi ruaj ** tab sis nyob ntawm:
- ** TUBE sab nraud ntawm lub cheeb (OD) **
- ** Kev tsim qauv ** (piv txwv li, T1, T2, T2, T4, T4 cov chav kawm siab)
Thicknesses range from **≈1.8 mm (small OD)** to **>40 hli (loj od) **. Cov kev ntseeg tshwj xeeb yog tabulated nyob rau hauv tus qauv raws li OD thiab kev tsim qauv.
5. **
Qhov tsawg kawg nkaus phab ntsa tuab nyob ntawm:
- ** Tsim Tsim Nyog ** Thiab ** Kub **
- ** Cov Yeeb Nkab Khoom Siv Zog ** (tawm \/ tensile)
- ** Cov qauv kev nyab xeeb \/ cim rau ** (piv txwv li, ASME B31.3, thiab 13480)
- ** Qog \/ Kev Txawj Ntse \/
Tus qauv dav dav yog:
\\ [t _ {min} {= \\ cdot d} {\\ cdot e + p \\ cdot y)} + a \\]
Qhov twg:
- \\ (p \\): tsim kev tsim
- \\ (d \\): Yeeb Nkab OD
