| Ibanga le-10 | ≥450 | ≥260 | ≥30 | -75℃ |
Iimfuno zenkqubo
Inkqubo yokuvelisa: engenamthungo okanye edibeneyo (kodwa i-Gr.6 idla ngokufuna engenamthungo)
Unyango lobushushu: ukulungisa okanye ukulungisa kunye nokulungisa
Uvavanyo olungonakalisiyo: Uvavanyo lwe-100% ye-ultrasonic okanye ye-eddy current
Uvavanyo loxinzelelo lwe-hydraulic: luhlala luphindwe kayi-1.5 uxinzelelo olusebenzayo
Ukuhlelwa kwezinto
I-ASTM A333/A333M ineeklasi zezinto ezahlukeneyo, kwaye ukwakheka kweekhemikhali zeklasi nganye kwahlukile:
1. Ibanga 1
Ikhabhoni (C): ≤0.30%
IManganese (Mn): 0.40-1.06%
I-Phosphorus (P): ≤0.025%
I-Sulfur (S): ≤0.025%
I-Silicon (Si): ≥0.10%
2. Ibanga lesi-3
Umxholo weNickel (Ni) umalunga ne-3.5%, kwaye ukuqina kobushushu obuphantsi kungcono.
3. Ibanga lesi-6
Ikhabhoni (C): ≤0.30%
IManganese (Mn): 0.29-1.06%
I-Phosphorus (P): ≤0.025%
I-Sulfur (S): ≤0.025%
I-Silicon (Si): ≥0.10%
4. Ibanga lesi-8
Izinto zentsimbi engenasici zase-Austenitic, zihlala ziyi-304 okanye i-304L
5. Ibanga lesi-9
Umxholo weNickel (Ni) umalunga ne-1.5%, phakathi kweGr.3 kunye neGr.6
6. Ibanga le-10
Intsimbi ethambileyo ene-molybdenum (Mo) ukuphucula ukumelana nokugqwala
Uluhlu lobushushu olusebenzayo lwebanga ngalinye
| Ibanga | Ubuncinci bobushushu bokusebenza |
| Isigaba 1 | -45℃ |
| Isigaba 3 | -100℃ |
| Ibanga lesi-4 | -110℃ |
| Isigaba 6 | -45℃ |
| Ibanga lesi-7 | -100℃ |
| Kuhle | -195℃ |
| Isigaba 9 | -110℃ |
| Ibanga le-10 | -75℃ |
Ingcaciso eyongezelelweyo
1. I-Gr.6 yeyona grade isetyenziswa kakhulu, ifanelekile ngakumbi kwiindawo ezinobushushu obuphantsi ezifana ne-LNG (-162℃)
2. Ukukhethwa kwamanqanaba ahlukeneyo kuxhomekeke kubushushu boyilo, iimpawu eziphakathi kunye nokuqwalaselwa kweendleko
3. Zonke iintlobo zeepayipi zentsimbi zivavanywa kubushushu obuphantsi ukuqinisekisa ukuqina kwazo
4. Kwiipayipi zentsimbi ezidityanisiweyo, unyango olufanelekileyo lobushushu luyafuneka emva kokudityaniselwa ukubuyisela iipropati zezinto ezibonakalayo
5. Xa uthenga, kufuneka kukhethwe umgangatho wezinto ezifanelekileyo ngokwendawo ethile yesicelo, kwaye isatifikethi sezinto kunye nengxelo yovavanyo kufuneka ziqinisekiswe ngokungqongqo.
