Embonini yamapayipi,I-API 5Lkuyindinganiso egcina konke kuhlangene. Kodwa uma ubhekisisa imininingwane, akuyona idokhumenti ethi “usayizi owodwa ufanelana nakho konke”. Ukukhetha phakathi kwe-I-API 5L Ibanga BkanyeI-API 5L X70, noma ukunquma ukuthi iphrojekthi iyayidinga ngempela i-PSL2, yilapho ubunjiniyela buba nzima khona.
Isisekelo: I-PSL1 vs. I-PSL2
Isinqumo sokuqala kunoma iyiphi inqubo yokuthenga yizinga lokucaciswa komkhiqizo.I-API 5L PSL1ilungele izinhlelo zokusebenza eziyisisekelo, i-API 5L PSL2 iyisilwane esihlukile ngokuphelele. Yenzelwe izindawo lapho izingozi ziphakeme khona, njengemigqa yegesi enomfutho ophezulu noma amapulatifomu asogwini lolwandle.
| Fukudla | I-PSL1 | I-PSL2 |
|---|---|---|
| Ukuhlolwa Komthelela We-CVN Okuphoqelekile | No | Yebo |
| Uphahla Oluqinile Lokukhiqiza | Akukho | Okuphoqelekile (Kunciphisa amandla angaphezu kwavamile) |
| Isilinganiso Sokukhuphula Okuphezulu | Akukho | Ngokuvamile 0.93 |
| Ukulandelela | Okuyisisekelo | Kudingeka Ukulandelela Okugcwele |
| Umugqa Wokushisela i-NDT | Okuyisisekelo | Okuphoqelekile (i-Radiographic noma i-Ultrasonic) |
I-Chemistry: Ukudlulela Ngale “kobumsulwa”
Uma abantu bekhuluma “ngekhwalithi” ye-PSL2, bavame ukukhuluma ngekhemikhali. Imikhawulo ye-Phosphorus ne-Sulfur iqine kakhulu ku-PSL2 ngoba lokhu kungcola yikona okuholela ekwehlulekeni emkhakheni.
Nansi indlela i-chemistry evame ukuwohloka ngayo ngamamaki ambalwa avamile:
| Isici (Ubuningi %) | Ibanga B le-PSL1 | Ibanga B le-PSL2 | I-PSL2 X70 |
|---|---|---|---|
| Ikhabhoni (C) | 0.26 | 0.22 | 0.22 |
| I-Manganese (Mn) | 1.20 | 1.20 | 1.65 |
| I-Phosphorus (P) | 0.030 | 0.025 | 0.025 |
| I-Sulfur (S) | 0.030 | 0.015 | 0.015 |
Into eyodwa okufanele uyiqaphele yi-CEV. Ku-PSL2, i-CEV akuyona nje isiphakamiso; iwumkhawulo oqinile oqinisekisa ukuthi ipayipi lingashiselwa ensimini ngaphandle kokuqhekeka. Uma ikhabhoni iphansi kakhulu, umshini uzoshintshela kufomula ye-Pcm ukuze unikeze isithombe esinembile sokushiselwa.
Ukusebenza Kwemishini Namandla
Igama lebanga likutshela amandla okukhiqiza amancane kakhulu. Ipayipi le-X52 linomthamo omncane kakhulu we-psi ongu-52,000. Kodwa ku-PSL2, amandla okukhiqiza "aphezulu" abaluleke kakhulu njengomthamo omncane kakhulu. Uma ipayipi liqinile kakhulu noma liqinile kakhulu, lilahlekelwa amandla okuguquguquka adingekayo ukuze liphathe ukunyakaza komhlabathi noma ukucindezela.
| Ibanga | Inzuzo Encane (i-MPa) | I-Max Yield (MPa) | I-Min Tensile (MPa) | Ukuqina Okuphezulu (i-MPa) |
|---|---|---|---|---|
| Ibanga B | 245 | 450 | 415 | 760 |
| X52 | 360 | 530 | 460 | 760 |
| I-X60 | 415 | 565 | 520 | 760 |
| X70 | 485 | 635 | 570 | 760 |
Ukuhlolwa Kokucindezela: Ifomula Ye-Hydrostatic
Yonke inhlanganisela yepayipi le-API 5L kufanele iphumelele ukuhlolwa kwamanzi. Kuwubufakazi obuphelele bokuthi umshini wokugaya wenze umsebenzi wawo. Ingcindezi esetshenzisiwe akuyona inombolo engahleliwe; ibalwa ngokusekelwe ezicini zomzimba zepayipi kusetshenziswa ifomula elandelayo:
Kulesi sibalo,Pingcindezi yokuhlola,tukujiya kodonga, futhiDububanzi bangaphandle. I-variableSimele ukucindezeleka kwefayibha, okuvame ukuba phakathi kuka-60% no-90% wamandla amancane okukhiqiza ipayipi acacisiwe. Ku-PSL2, ukuhlolwa kuvame ukugcinwa isikhathi eside ukuqinisekisa ukuthi umthungo wokushisela uphelele.
Isevisi Emnandi
Uma ipayipi lakho liphethe igesi "emuncu" (H2S), amamaki ajwayelekile ngeke akuqede. Kufanele ubheke izijobelelo ze-“MS” noma ze-“NS”, njenge-X52MS. Lawa mapayipi ahlolwa ukuhlolwa kwe-HIC. I-chemistry lapha idlulele kakhulu, amazinga e-Sulfur avame ukucindezelwa afike ku-0.003% ukuvimbela igesi ukuthi ingadli insimbi ngaphakathi nangaphandle.
Icebiso Lokuhlola Elisebenzayo
Uma ulinganisa ipayipi, khumbula ukuthi i-API 5L ivumela ukubekezelelana kancane kobukhulu bodonga. Kodwa-ke, ku-PSL2, lezo zibekezelelano ziqinile kakhulu. Sebenzisa i-geyiji yobukhulu be-ultrasonic elinganisiwe futhi uqiniseke ukuthi awulinganisi kahle onqenqemeni olusikiwe lapho isaha lingase lishiye khona i-burr. Ukuthola ukufundwa okunembile kude nokuphela kwepayipi kuyindlela kuphela yokuqinisekisa ukuthi uthola insimbi oyikhokhele.
