Ukwakheka kwamakhemikhali
| Isici | Imfuneko | Ukubaluleka |
|---|---|---|
| Carbon (C) | 0.06% – 0.18% | Ilinganiselwe ukuze ibe namandla futhi iweldwe kalula |
| I-Manganese (Mn) | 0.27% – 0.63% | Inikeza amandla, ilawula i-hardenability |
| I-Phosphorus (P) | ≤0.035% | Okuphansi ukuze kube nokushisela okuhle |
| Isulfure (S) | ≤0.035% | Aphansi ukuze akwazi ukubunjwa kahle |
💡 Ukulawulwa kwekhabhoni ne-manganese iqinisekisa izakhiwo zemishini ezihambisanayo nokushisela okuhle kakhulu ekwakheni ama-boiler.
Izici zemishini
| Impahla | Inani | Ukubaluleka kwe-Boiler Service |
|---|---|---|
| Amandla Okuqina | ≥325 MPa (47,000 psi) | Kulungele ukucindezela okuphezulu |
| Amandla okuvumela (Yield Strength) | ≥180 MPa (26,000 psi) | Ukulinganisela okuhle kwamandla nokuguquguquka |
| Ukunwebeka | ≥35% | Ukuguquguquka okuhle kokwakha |
| Ukuqina (HRB) | ≤77 | Iqinile kancane kune-SA179 ukuze imelane nokucindezela okuphezulu |
Ukubekezeleka Kobukhulu – Kudonswe Kubanda
| OD (mm) | Ukubekezelela (mm) | WT (mm) | Ukubekezelela (mm) |
|---|---|---|---|
| <25.4 | ±0.10 | <2.0 | ±0.10 |
| 25.4 – 38.1 | ±0.13 | 2.0 – 3.0 | ±0.12 |

Inqubo Yokukhiqiza – Cold Drawing
Inqubo Yokudonsa Okubandayo Yamashubhu E-Boiler:
-
Amashubhu agingqikwe ashiswa ahlanzwa ukuze kususwe isikali
-
Ukudonsa okubandayo linciphisa ngqo ububanzi – likhulisa amandla
-
Ukuthambisa (Annealing) (ukujwayela) – kubuyisela ukuqina, kuqinisekisa ukwakheka okufanayo
-
Ukuqondisa – iqinisekisa ukuthi i-boiler ime ngqo
-
Ukusika okunembile – ngokwezidingo eziqondile zobude bekhasimende
-
Ukuhlolwa okungu-100% kwe-NDT kanye ne-hydrostatic – iqinisekisa ubuqotho
ASME SA192 vs ASME SA179
| Isici | ASME SA179 | I-ASME SA192 |
|---|---|---|
| Ukusetshenziswa Okuyisemqoka | Ama-heat exchanger, ama-condenser | Ama-boiler omfutho ophezulu |
| Ububanzi be-OD | 1/8″ – 3″ | 1/8″ – 7″ (inkulu) |
| Ubukhulu Bodonga | Ukuncane (0.5-3mm) | Maphakathi nokusinda (1-15mm) |
| Ukuqina (HRB) | ≤72 | ≤77 |
| Izinga lokucindezela | Phansi kuya kokumaphakathi | Phezulu |
| Ukusetshenziswa | Imishini yokudlulisa ukushisa | Ama-boiler, ama-superheater |
💡 I-SA192 yakhelwe ukusebenza kwama-boiler omfutho ophezulu ngamandla okusekela udonga olusindayo nobubanzi obukhulu.
Izinhlelo Zokusebenza Eziyinhloko
| Ingxenye Yebhoyila | I-OD Ejwayelekile | Ububanzi be-WT | Izinga lokushisa lokusebenza | Ukufaneleka |
|---|---|---|---|---|
| Amashubhu odonga lwamanzi | 2″ – 3″ | 4.0 – 6.0mm | 500-700°F | Kuhle kakhulu |
| Amashubhu e-Economizer | 1.5″ – 2.5″ | 3.0 – 5.0mm | 400-600°F | Kuhle Kakhulu |
| I-superheater yokushisa ephansi | 1.5″ – 2.5″ | 4.0 – 6.0mm | 700-850°F | Kuhle |
| Amashubhu e-downcomer | 3″ – 7″ | 5.0 – 10.0mm | 400-600°F | Kuhle Kakhulu |
💡 I-SA192 ihlanganisa izicelo eziningi zamashubhu ama-boiler angaphansi kwe-subcritical – izindonga zamanzi, ama-economizer, nama-superheater asezingeni eliphansi lokushisa.
Kungani Ukhetha Amashubhu Ethu E-ASTM A192?
