Ukuqalisa
Le khasiI-ASTM A312 UNS S30815 253MA I-PIPELOS E-STARINLELORIngabe i-alloy yensimbi esebenza kakhulu ye-auntenitic engenasici eyaziwa ngokumelana kwayo okuphezulu kwi-oxidation ephezulu yokushisa, ukugqwala, kanye nezindawo ezinhle kakhulu zemishini ezindaweni zokushisa eziphakeme.253AYakhelwe ngqo insizakalo kuzicelo ezidinga ukuqina okuphezulu kokushisa, ikakhulukazi esithandweni sokwelashwa okushisa kanye nokushisa. Ukumelana kwaso okuvelele ekulinganiseni, ukuthuthuka, kanye ne-oxidation ejwayelekile kwenza kube yinto ethembekile yezindawo ezedlulele.
Leli banga lensimbi engenasici lisetshenziswa kabanzi kuzinhlelo zokusebenza zezimboni eziphakeme kakhulu futhi lilungele izinhlelo zokusebenza lapho amandla aphezulu kanye nokumelana oxidation kubucayi.
Amazinga nokucaciswa
Le khasiI-ASTM A312 UNS S30815 253MA I-PIPELOS E-STARINLELORyenziwa ngokwezindinganiso ezilandelayo:
- I-ASTM A312: Ukucaciswa okujwayelekile kwe-seamless, ama-weldicled, kanye namapayipi ama-autenitic aututenitic angenasici
- Us s30815: Uhlelo lokufaka izinombolo oluhlanganisiwe lwezinto zokwakha luhlonza lokhu njengebanga eliphakeme lensimbi engenasici.
- En 10088-2: Izinga le-European ngensimbi engenasici, ukumboza izidingo zalolu hlobo lwezinto, izakhiwo zemishini, nokuhlola.
Ukwakheka kwamakhemikhali(% ngesisindo)
Ukwakheka kwamakhemikhali kweI-253MA (ANS S30815)yakhelwe ukuhlinzeka ngokumelana kahle ne-oxidation kanye namandla aphezulu okushisa. Ukwakheka okujwayelekile kungokulandelayo:
| Isithako semvelo | Ukwakheka (%) |
| Chromium (cr) | I-20.00 - 23.00% |
| Nickel (NI) | 24.00 - 26.00% |
| Silicon (si) | I-1.50 - 2.50% |
| IManganese (MN) | 1.00 - 2.00% |

| Phosphorus (p) | ≤ 0.045% |
| Isibabule (s) | ≤ 0.030% |
| Nitrogen (n) | 0.10 - 0.30% |
| Iron (FE) | Ukuzimelela |
Izakhiwo ezibonakalayo: Izici ezibalulekile
253A(Ama-S30815) ahlanganisa amandla aphezulu okushisa aphezulu ngokumelana ne-oxidation. Lokhu kwenza kube kuhle ukuthola izicelo ezindaweni ezingejwayelekile, njengezindela nokushintshaniswa kokushisa. Izinto eziqukethwe zinokuqukethwe okuphezulu kwe-chromium nokuqukethwe kwe-nickel, ukuhlinzeka ngokumelana okuhle ne-oxidation emazingeni okushisa afinyelela ku-1150 ° C (2100 ° F).

Inqubo yokukhiqiza: ubuciko bokunemba
Ukukhiqizwa kweAmapayipi ensimbi engagqwaliIlandela izindlela zokukhiqiza zakamuva ukuqinisekisa ikhwalithi ephezulu nokuqina:
- Ukukhiqizwa kwepayipi kwe-Seamless: Kukhiqizwe ngokuxoshwa, ukubhoboza okujikelezayo, nezinqubo ezibucayi ukudala amapayipi angenamthungo anobukhulu obudongeni.
- Inqubo ebandayo yokusebenza: Kusetshenziswa izinqubo zokudweba noma zokushayela izimbambo zokuthola ubukhulu obuqondile kanye nezindawo ezibushelelezi.
- Ukwelashwa okushisa: Amapayipi abhekene nokwelashwa okushisa emazingeni okushisa athile okuthuthukisa izakhiwo zawo zemishini nokusebenza okushisa okuphezulu.
- Ukuthatha nokuhamba: Amapayipi athathwa asuswe ukuze asuse amafilimu akwa-oxide kanye nama-oxide futhi aqhume ukuze aqinisekise ukumelana nokuqhubeka kokugqwala.
Ukuhlola nokuhlola: Ukuqinisekiswa kwekhwalithi
I-Wovic Steel ilandela iphrothokholi yokuhlola eqinile yokuqinisekisa ikhwalithi ephezulu kakhuluAmapayipi ensimbi engagqwali:
- Ukuhlaziywa Kwamakhemikhali Ukuhlaziywa: Kuqinisekisiwe kusetshenziswa amasu we-spectroscopic ukuqinisekisa ukuthi i-alloy ihlangabezana nezingoma ezibekiwe.
- Ukuhlolwa Kwemishini: Tensile, ubunzima, kanye nokuhlolwa komthelela ukuqinisekisa ukusebenza okubonakalayo emazingeni okushisa ahlukahlukene.
- Ukuhlolwa kweHydrostatic: Amapayipi ahlolwe ukuqina kwengcindezi ukuqinisekisa ukusebenza kwamahhala okuvuzayo.
- Ukuhlolwa okungelonakalisa okubhubhisayo (NDT): Kubandakanya ukuhlolwa kwe-ultrasonic, i-Eddy yamanje, kanye nokuhlolwa kwedayi
- Ukuhlolwa okubonakalayo nosayizi: Ipayipi ngalinye lihlolwe ngokubonakalayo kokuqedwa komhlaba, futhi ukunemba okubucayi kuhlolwe ukucaciswa.
Ngeminye imininingwane noma isilinganiso sangokwezifiso, thintana nensimbi ye-Womec namuhla!
