Imingcele yomkhiqizo wepayipi lensimbi engenamthungo ye-ASTM A333/A333M kanye nokwethulwa kwezinto ezibonakalayo
Ukubuka Okujwayelekile
I-ASTM A333/A333M iyindinganiso "yepayipi lensimbi elingenamthungo nelihlanganisiwe lokushisa okuphansi" eyakhiwe yi-American Society for Testing and Materials, efanelekela izinhlelo zamapayipi okucindezela ezindaweni eziphansi lokushisa.
Amapharamitha omkhiqizo
Ububanzi bosayizi
Ububanzi bangaphandle: 1/8" (10.3mm) ~ 26" (660mm)
Ubukhulu bodonga: SCH 10 ~ SCH 160
Ubude: ngokuvamile 5.8m ~ 12.2m (ubude obungaguquki noma ubude obungaguquki)
Izidingo zokusebenza kwemishini
| Ibanga | Amandla okudonsa (i-MPa) | Amandla okukhiqiza (i-MPa) | Ukwelulwa (%) | Izinga lokushisa lokuhlolwa komthelela |
| Isigaba 1 | ≥380 | ≥205 | ≥35 | -45℃ |
| Isigaba 3 | ≥450 | ≥240 | ≥30 | -100℃ |
| Isigaba 4 | ≥415 | ≥240 | ≥30 | -110℃ |

| Isigaba 7 | ≥485 | ≥315 | ≥30 | -100℃ |
| Isigaba 8 | ≥690 | ≥515 | ≥20 | -195℃ |
| Isigaba 9 | ≥435 | ≥315 | ≥30 | -110℃ |
| Isigaba 10 | ≥450 | ≥260 | ≥30 | -75℃ |
Izidingo zenqubo
Inqubo yokukhiqiza: engenamthungo noma ehlanganisiwe (kodwa i-Gr.6 ngokuvamile idinga engenamthungo)
Ukwelashwa ngokushisa: ukwenza kube ngokwejwayelekile noma ngokwejwayelekile kanye nokushisa
Ukuhlolwa okungabhubhisi: Ukuhlolwa kwamanje kwe-ultrasonic noma kwe-eddy okungu-100%
Ukuhlolwa kwengcindezi ye-Hydraulic: ngokuvamile ingcindezi yokusebenza ephindwe ka-1.5
Ukuhlukaniswa kwezinto
I-ASTM A333/A333M iqukethe amamaki amaningi ezinto ezibonakalayo, futhi ukwakheka kwamakhemikhali kwebanga ngalinye kuhlukile:
1. Isigaba 1
Ikhabhoni (C): ≤0.30%
I-Manganese (Mn): 0.40-1.06%
I-Phosphorus (P): ≤0.025%
Isibabule (S): ≤0.025%
I-Silicon (Si): ≥0.10%
2. Isigaba 3
Okuqukethwe kwe-nickel (Ni) cishe kungama-3.5%, kanye nokuqina okungcono kwezinga lokushisa eliphansi
3. Isigaba 6
Ikhabhoni (C): ≤0.30%
I-Manganese (Mn): 0.29-1.06%
I-Phosphorus (P): ≤0.025%
Isibabule (S): ≤0.025%
I-Silicon (Si): ≥0.10%
4. Isigaba 8
Izinto zensimbi engagqwali zase-Austenitic, ngokuvamile ezingama-304 noma ezingama-304L
5. Isigaba 9
Okuqukethwe kwe-nickel (Ni) cishe ku-1.5%, phakathi kwe-Gr.3 ne-Gr.6
6. Isigaba 10
Insimbi ephansi ye-alloy equkethe i-molybdenum (Mo) ukuthuthukisa ukumelana nokugqwala
Ububanzi bokushisa obusebenzayo bebanga ngalinye
| Ibanga | Izinga lokushisa eliphansi lokusebenza |
| Isigaba 1 | -45℃ |
| Isigaba 3 | -100℃ |
| Isigaba 4 | -110℃ |
| Isigaba 6 | -45℃ |
| Isigaba 7 | -100℃ |
| Isigaba 8 | -195℃ |
| Isigaba 9 | -110℃ |
| Isigaba 10 | -75℃ |
Incazelo eyengeziwe
1. I-Gr.6 iyibanga elisetshenziswa kakhulu, elifaneleka kakhulu ezindaweni eziphansi zokushisa njenge-LNG (-162℃)
2. Ukukhethwa kwamabanga ahlukene kuncike ekushiseni komklamo, izici eziphakathi kanye nokucatshangelwa kwezindleko
3. Zonke izinhlobo zamapayipi ensimbi zihlolwa ngokushisa okuphansi ukuqinisekisa ukuqina kwawo
4. Kumapayipi ensimbi ahlanganisiwe, ukwelashwa kokushisa okufanele kuyadingeka ngemva kokushisela ukuze kubuyiselwe izakhiwo zezinto ezibonakalayo
5. Uma uthenga, izinga lezinto ezifanele kufanele likhethwe ngokuya ngendawo ethile yokusetshenziswa, futhi isitifiketi sezinto kanye nombiko wokuhlolwa kufanele kuqinisekiswe ngokuqinile.
