Ukwakheka Kwekhemikhali – P235GH
| Element | C | Si | Mn | P max | I-S max | I-Al |
|---|---|---|---|---|---|---|
| Imfuneko | ≤0.16 | ≤0.35 | 0.60-1.20 | 0.025 | 0.015 | ≥0.020 |
💡 I-phosphorus ne-sulphur ephansi iqinisekisa ukuqina nokuhambisana okuhle kokushiselwa emsebenzini wemishini yengcindezi. I-Aluminiyamu (≥0.020%) ihlinzeka ngokucolisiswa kwezinhlamvu ukuze kuthuthukiswe izakhiwo.
Izici Zomshini
| Impahla | Inani | Ukubaluleka |
|---|---|---|
| Amandla Okudonsa | 360 – 500 MPa | Ilungele imishini yengcindezi |
| Amandla Okuvumela | ≥235 MPa | Amandla amahle okucindezela okuvamile |
| Ukunwetshwa | ≥25% | Ukuqina okuhle ekubumbeni |
| Umthelela we-Charpy (TC2) | 27J ubuncane ku-0°C | Ukuqina okushisayo okuphansi okuqinisekisiwe |
I-TC1 vs I-TC2 – Amazinga Ekhwalithi
| Isici | I-TC1 | TC2 |
|---|---|---|
| Ukuhlolwa Komthelela kwe-Charpy | Akudingekile | Kuyadingeka (27J ku-0°C) |
| Izidingo ze-NDT | Okujwayelekile | Ukwamukelwa okuqinile |
| Ukusetshenziswa Okujwayelekile | Imishini ejwayelekile yengcindezi | Izicelo ezibucayi, ukuqala okushisayo okuphansi |
| Izindleko | $ | $$ |
💡 Khetha i-TC2 uma kudingeka ukuqina komthelela – ngokuvamile icaciselwa izimo zokuqala ezingeni lokushisa eliphansi noma imishini yomfutho ebucayi.
Inqubo Yokukhiqiza – Ukudonsa Okubandayo
Inqubo Yokudonsa Ebandayo Yamashubhu Engcindezi:
-
Amashubhu agingqiwe ashisayo ayahlanzwa nge-pickle ukuze kususwe isikali
-
Ukudonsa okubandayo linciphisa ngqo ububanzi – likhulisa amandla
-
Ukuthambisa (ukujwayela) – iqinisekisa ukwakheka kwezinhlayiya ezinhle, ibuyisela ukuvumeka
-
Ukuqondisa – iqinisekisa ukuqondakala kokufakwa
-
Ukusika ngokunemba – ukuze kufane ubude obunembile bekhasimende
-
Ukuhlolwa kwe-NDT okungu-100% nokuhlolwa kwe-hydrostatic – iqinisekisa ubuqotho
-
Ukuhlolwa komthelela kwe-Charpy (TC2) – iqinisekisa ukuqina kwezinga lokushisa eliphansi
Amandla Okuvumela Izinga Lokushisa Eliphezulu (I-Rp0.2 MPa min)
| Temp (°C) | 50 | 100 | 150 | 200 | 250 | 300 | 350 | 400 |
|---|---|---|---|---|---|---|---|---|
| I-P235GH | 190 | 180 | 170 | 155 | 145 | 135 | 130 | 120 |
💡 I-P235GH igcina amandla amahle kuze kufike ku-400°C – ngaphezu kwale izinga lokushisa, sebenzisa i-16Mo3 noma i-13CrMo4-5 alloy grades.
Izicelo Eziyinhloko
| Imboni | Ukusetshenziswa | Ikhwalithi Enconyiwe |
|---|---|---|
| Ukukhiqiza Amandla | Amashubhu e-boiler, umusi womfutho ophansi | TC1, TC2 |
| Imithelela Yomfutho | Izigubhu, ama-accumulator, ama-headers | TC1, TC2 |
| Ama-Boiler Ezimboni | Ama-steam generator, ama-economizer | I-TC1 |
| Izishintshi Zokushisa | Ama-Shell nama-tube assemblies | I-TC1, I-TC2 |
| I-Petrochemical | Ukuhambisa ipayipi lokushisa okuphezulu | TC2 |
💡 I-TC2 inconyulwa ukusetshenziswa ezinhlelweni ezibalulekile edinga ukuqina komthelela ezimweni zokuqala ezingashisi.
Inkomba Yokuhlangana ye-DIN 17175
