Imikhiqizo Izigaba

2205 duplex insimbi engagqwali

Ukwakheka kwamakhemikhali: 22% chromium, 5% nickel, 3% molybdenum, kanye 0.18% nitrogen. Izakhiwo zikamshini: Amandla Aqinile:620MPa, Amandla Esivuno: 450MPa, Ukwelulwa:25%.

Ukumelana nokugqwala: Inokumelana nokugqwala okuhle kakhulu futhi ilungele imidiya edlayo ehlukahlukene, okuhlanganisa i-asidi, i-alkali, usawoti, njll. Ukumelana nokugqwala kokucindezeleka kwe-chloride kuphakeme kunensimbi evamile ye-austenitic.

Isici:

Ukumelana ne-oxidation: I-310S insimbi engagqwali inokumelana okuhle ne-oxidation futhi ingagcina uzinzo ezindaweni zokushisa okuphezulu.

Ukumelana nokugqwala: Ngenxa yokuqukethwe kwayo okuphezulu kwe-chromium ne-nickel, insimbi engagqwali engu-310S inokumelana nokugqwala okuhle futhi ifanele indawo ehlukahlukene egqwalayo.

Ubulukhuni obuphezulu be-martensitic insimbi engagqwali yepayipi yokushisela yezimboni isetshenziselwa ikakhulukazi amandla aphezulu nobulukhuni bezicelo, futhi idinga ukumelana nokugqwala okuthile. Insimbi engagqwali ye-Martensitic yethiwa ngobulukhuni bayo obuphezulu namandla ngemva kokwelashwa kokushisa, futhi ifaneleka ukwakhiwa kwamathuluzi okusika, iziphethu, ama-bearing, ama-valve, imizimba yokupompa nezinye izingxenye.

I-904L insimbi engagqwali iyinsimbi engagqwali eyi-super austenitic enokumelana nokugqwala okuphezulu kakhulu, ikakhulukazi ezindaweni eziqukethe ama-chlorides.Iyinsimbi engagqwali enengxubevange ephezulu ene-chromium ephezulu, i-nickel ne-molybdenum, kanye nenani elincane lethusi ne-nitrogen.

I-C276/S32760 (Hastelloy C-276)

Ukwakheka kwamakhemikhali: Ingxubevange ye-C276 iqukethe ingxenye ephezulu ye-nickel (cishe ama-59%), kanye ne-molybdenum, i-chromium, i-tungsten nezinye izakhi. Ifomula yayo yamakhemikhali imvamisa ichazwa ngokuthi 00Cr15Ni60Mo16W4.

I-Hastelloy GH3044

Ukwakheka kwamakhemikhali: I-GH3044 iyisisombululo esiqinile esisekelwe ku-nickel-chromium superalloy, equkethe i-chromium ephezulu ne-tungsten okuqukethwe, kanye nenani elincane le-molybdenum, insimbi, i-aluminium nezinye izakhi.

Ukwakheka kwamakhemikhali: I-Incoloy 800 iyingxubevange ye-nickel-iron-chromium equkethe ingxenye ephezulu ye-nickel (cishe 30-35%), i-chromium (cishe 19-23%) nensimbi (cishe 39-45%).Iqukethe nenani elincane lekhabhoni, i-manganese, i-silicon nethusi.

Ukwakheka kwamakhemikhali: I-NO6600 iyingxube eqinile esekwe ku-nickel-chromium-iron equkethe i-nickel, i-chromium, insimbi nezinye izakhi. Izingxenye ezithile zingafaka i-nickel (mayelana ne-margin), i-chromium (cishe 19-23%), insimbi (cishe 5-10%), nenani elincane lekhabhoni, i-manganese, i-silicon, njll.

I-TP316L Stainless steel welded pipe iwuhlobo lwe-austenitic stainless steel material, iyingxenye ye-316, lapho "L" imele ikhabhoni ephansi (Ikhabhoni Ephansi). Le nto ifaneleka ngokukhethekile ukusetshenziswa ezimweni lapho i-welding idingeka khona ngenxa yezakhiwo zayo ezinhle kakhulu zokushisela kanye nokumelana nokugqwala. TP316L Insimbi engagqwali ashiselwe ipayipi isetshenziswa kabanzi embonini yamakhemikhali, petroleum, ukucubungula ukudla, imithi, ukwenza iphepha, Marine engineering kanye nezinye izimboni.

I-TP316Ti Stainless steel welded pipe iyinsimbi engenasici ye-austenitic, ingeyochungechunge lwe-316, iqukethe i-titanium njengento eqinisayo. Lokhu okuqukethwe kulungele ukusetshenziswa ezindaweni ezishisa kakhulu nezishisa kakhulu, njengakumakhemikhali, uphethiloli, ukucubungula ukudla, ukwenza imithi nezinye izimboni. I-TP316Ti Ukuqiniswa kwe-titanium kwepayipi elishiselwe lensimbi engenasici kusiza ukuvimbela ukugqwala kwe-intercrystalline, okubangelwa ukuhlobana okuqinile kwe-titanium ne-carbon, kanye nenhlanganisela ekhethwayo nekhabhoni ukwenza i-titanium carbide ezinzile, ukuze kuvinjelwe ukwakheka kwe-chromium carbide emngceleni wokusanhlamvu nokuvikela ukumelana nokugqwala.

I-15X25T iyizinga lensimbi, "15" imele okuqukethwe kwekhabhoni cishe okungaba ngu-0.15%, "X" imele okuqukethwe kwezakhi ze-alloying, futhi "25 T" ikhombisa ukuthi insimbi iqukethe u-25% wezinto ezihlanganisiwe. Ngokwendinganiso yesiRashiya, lolu hlobo lwensimbi luyingxenye yensimbi yesakhiwo se-alloy futhi ngokuvamile lusetshenziselwa ukukhiqiza izingxenye zemishini ezimelana nemithwalo ephezulu kanye nomthelela.

I-Anti-intercrystalline corrosion: Ngenxa yokwengezwa kwe-titanium, ipayipi elishiselwe insimbi engagqwali ye-TP 321 ingamelana nokugqwala kwe-intercrystalline, okubangelwa ukuhlobana okuqinile kwe-titanium ne-carbon, okukhethekile kuhlanganiswe nekhabhoni ukuze kwakhiwe i-titanium carbide ezinzile, ngaleyo ndlela ivimbele ukwakheka kwe-chromium carbide evikela i-corrosion, i-crystal resistance corrosion.
