|---|---|---|
| Amandla Okuqina | 360 – 500 MPa | Kufanelekile emishinini yokucindezela |
| Amandla Okuvumela | ≥235 MPa | Amandla amahle okucindezela okujwayelekile |
| Ukunwebeka | ≥25% | Ukunwebeka okuhle kakhulu kokubumba |
| Umphumela we-Charpy (TC2) | 27J min ku-0°C | Ukuqina okuqinisekisiwe ekushiseni okuphansi |
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 okuvamile | Imishini ejwayelekile yokucindezela | Izimo ezibucayi, ukuqala ekushiseni okuphansi |
| Izindleko | $ | $$ |
💡 Khetha i-TC2 lapho kudingeka ukuqina komthelela – ngokuvamile kucaciswa izimo zokuqala ezingeni lokushisa eliphansi noma imishini ebucayi yokucindezela.
Inqubo Yokukhiqiza – Ukudonsa Okubandayo
Inqubo Yokudonsa Okubandayo Yamashubhu Okucindezela:
-
Amashubhu agingqwe ashiswa (Hot rolled tubes) zihlanjululwa ukuze kususwe i-scale
-
Ukudonswa okubandayo (Cold drawing) linciphisa ngokunembile ububanzi – likhulisa amandla
-
Ukushiswa (ukujwayela) – iqinisekisa ukwakheka kwezinhlayiya ezinhle, ibuyisela ubumnene
-
Ukuqondisa – iqinisekisa ukuqondakala kokufakwa
-
Ukusika okunembile – ubude obunembile bokukhetha kwekhasimende
-
Ukuhlolwa okungu-100% NDT kanye nokuhlolwa kwe-hydrostatic – iqinisekisa ubuqotho
-
Ukuhlolwa komthelela kwe-Charpy (TC2) – iqinisekisa ukuqina ekushiseni okuphansi
Amandla Okuvumela Ezingeni Lokushisa Eliphakeme (Rp0.2 MPa min)
| Izinga lokushisa (°C) | 50 | 100 | 150 | 200 | 250 | 300 | 350 | 400 |
|---|---|---|---|---|---|---|---|---|
| P235GH | 190 | 180 | 170 | 155 | 145 | 135 | 130 | 120 |
💡 I-P235GH igcina amandla amahle kuze kufike ku-400°C – ngaphezu kwaleli zinga lokushisa, sebenzisa i-16Mo3 noma i-13CrMo4-5 alloy grades.
Izicelo Eziyinhloko
| Umkhakha wezimboni | Ukusetshenziswa | Ikhwalithi Enconyiweyo |
|---|---|---|
| Ukukhiqiza Amandla | Amapayipi e-boiler, umusi wokucindezela ophansi | I-TC1, i-TC2 |
| Imithwalo Yokucindezela | Amadrum, ama-accumulator, ama-header | TC1, TC2 |
| Amabhoyela Ezimboni | Ama-steam generator, ama-economizer | TC1 |
| Ama-Heat Exchangers | Ama-shell nama-tube assemblies | I-TC1, I-TC2 |
| I-Petrochemical | Ukusetshenziswa kwamapayipi okushisa okuphezulu | TC2 |
💡 I-TC2 inconywa ukuthi isetshenziselwe izinhlelo ezibalulekile okudinga ukuqina komthelela ezimweni zokuqala ezishisayo eziphansi.
I-DIN 17175 Cross-Reference
| I-EN 10216-2 | DIN 17175 (Ihoxisiwe) |
