Umhlinzeki Wamashubhu Ensimbi E-Carbon E-ERW E-ASTM A178
Okwe-Boiler & Superheater Service – I-OD 6~204mm | WT 1~18mm
Uhlolojikelele Lomkhiqizo
Okwethu I-ASTM A178 / I-ASME SA178 amashubhu e-carbon steel ahlanganiswe (ERW) aklanyelwe ngokukhethekile insiza yebhoyela nokushisisa ngaphezulu ekucindezelweni okuphansi kuya kokumaphakathi. Akhiqizwa ngokushisela ukumelana nogesi (ERW) ngaphandle kokwengeza insimbi yokugcwalisa, lawa mashubhu anikeza enye indlela engabizi kakhulu kumashubhu e-boiler angenamthungo kwizicelo ezingabalulekile.

Ukukhetha Ibanga
| Izinga | Ukutholakala Kwekhabhoni | Izinga Lamandla | Ukusetshenziswa Okungcono Kakhulu |
|---|---|---|---|
| A | Okuphansi (0.06-0.18%) | Izinga | Ukunakekela kwe-boiler okujwayelekile |
| C | Okuphakathi (≤0.35%) | Phezulu | Ama-boiler okushisa okuphezulu |
| D | I-Carbon-Manganese | Okuphezulu kakhulu | Insiza yokushisisa ngaphezulu edingekayo |
💡 Ibanga A liyona elonga kakhulu ukusetshenziswa kwe-boiler evamile. Ibanga C no-D linikeza amandla aphezulu ezinhlelweni ezidinga kakhulu.
Ukwakheka kwamakhemikhali
| Isici | Ibanga A | Ibanga C | Ibanga D |
|---|---|---|---|
| Ikhabhoni (C) | 0.06-0.18% | ≤0.35% | ≤0.27% |
| I-Manganese (Mn) | 0.27-0.63% | ≤0.80% | 1.00-1.50% |
| I-Phosphorus (P) | ≤0.035% | ≤0.035% | ≤0.030% |
| Isibabule (S) | ≤0.040% | ≤0.035% | ≤0.015% |
Izici Zemishini
| Ibanga | Amandla Okuqina (MPa) | Amandla Okukhiya (MPa) | Ukunwebeka (%) |
|---|---|---|---|
| C | ≥415 | ≥255 | ≥30 |
| D | ≥485 | ≥275 | ≥30 |
📌 Izakhiwo zemishini zisebenza kumaGrade C no-D. IGrade A ivamise ukusetshenziselwa umsebenzi ojwayelekile lapho izidingo zamandla athile zingabalulekile.
Inqubo Yokukhiqiza – ERW (Ukushisela Ukumelana Nogesi)
Izinhlobo Eziyinhloko Zenqubo ye-ERW:
-
Ikhoyili lensimbi – Into yokuqala i-carbon steel strip esezingeni eliphezulu
-
Ukubumba – Umugqa ugotshwa ube umumo oyisilinda
-
Ukushisela kwe-ERW – Ukushisela ukumelana nogesi okungenaza-frequency ephezulu (akukho insimbi yokugcwalisa)
-
Ukwelashwa ngokushisa – Kushiswa kabusha ngemva kokushisela – kukhulula ingcindezi emthonjeni wokushisela
-
Ukulinganisa – Ububanzi bokugcina bufinyelelwa ngokudlula kuma-sizing rolls
-
Ukuhlolwa kwe-NDT okungu-100% – Ukuhlolwa komthungo wokushisela nokuhlolwa kwe-hydrostatic
I-ASTM A178 ngokuqhathanisa namashubhu e-boiler angenamthungo (SA192/SA179)
| Isici | ASTM A178 (ERW) | Okungenamthungo (SA192/SA179) |
|---|---|---|
| Ukukhiqiza | I-ERW ishisiwe (ngaphandle kwensimbi yokugcwalisa) | Ezingenamthungo |
| Izindleko | Phansi (konga kakhulu) | Phezulu |
| Isilinganiso sokucindezela | Maphakathi | Eliphakeme Kakhulu |
| Umthungo wokushisela | Kukhona (kushiswe ngokukhethekile) | Akukho mthungo wokushisela |
| Kungcono Kakhulu | Okungabalulekile, okubiza imali | Ukucindezela okuphezulu okubucayi |
💡 Khetha i-ASTM A178 kumaphrojekthi anesabelomali esilinganiselwe lapho izidingo zokucindezela zilingene futhi amashubhu angenamthungo engacaciswanga.
