Imikhiqizo Izigaba

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.

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

Insimbi engagqwali ye-310S ifaneleka ngokukhethekile ukusetshenziswa ezindaweni ezishisa kakhulu, isibonelo ezinhlelweni ezifana neziko zokushisa ukushisa, amakamelo omlilo, ama-boilers, izinto zamakhemikhali, izishintshisi zokushisa, namashubhu esithandweni somlilo.

Ukwakheka: 409 insimbi engagqwali iyinsimbi engagqwali ye-austenitic enokuqukethwe okuphezulu kwe-chromium (cishe u-10.5-11.7%) kanye nokuqukethwe kwekhabhoni ephansi.Lokhu kwakheka kwenza insimbi engagqwali engu-409 ingabi-zibuthe futhi imelane nokugqwala.

I-904L iyinsimbi engagqwali eyi-super-austenitic enokumelana nokugqwala okuphezulu kakhulu, ikakhulukazi ezindaweni eziqukethe ama-ion e-chloride. Le nto iqukethe i-nickel ephezulu kanye nokuqukethwe kwe-molybdenum, kanye nenani elilinganiselwe lethusi, elinikeza ukumelana nokugqwala okuhle kakhulu ezindaweni ezine-acidic, alkaline, ne-saline.904L insimbi engagqwali isetshenziswa kabanzi embonini yamakhemikhali, i-petroleum, ukwenza iphepha, ukucubungula ukudla, ubunjiniyela basolwandle kanye nezinye izimboni.

I-Hastelloy C-276 iyingxubevange esekelwe ku-nickel equkethe izakhi ezifana ne-molybdenum, i-chromium ne-tungsten, eyinikeza ukumelana nokugqwala okuhle kakhulu ezindaweni ezigqwalile ezihlukene, ezifanele ukusetshenziswa ezindaweni eziqukethe i-chloride. I-S32760 (Eyaziwa nangokuthi i-Super Dual-phase Steel 2507) iyinsimbi engagqwali enezigaba ezimbili ehlanganisa okuhle kwe-austenite nensimbi engagqwali yomzimba, enamandla aphakeme kanye nokumelana nokugqwala okungcono kwamabala kanye nokumelana nokugqwala kwegebe.

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.

I-TP304L Inguqulo yepayipi yensimbi engagqwali engu-304L, iyinsimbi engagqwali ene-carbon austenitic ephansi, ingeyezinga le-ASTM A312. Insimbi engagqwali engu-304L iyinguqulo ye-carbon ephansi ye-304 yensimbi engagqwali, futhi okuqukethwe kwayo kwekhabhoni kulawulwa ngaphansi kuka-0.03%, okukunikeza ukumelana nokugqwala okungcono kwe-intercrystalline ngesikhathi se-welding.304L insimbi engagqwali isetshenziswa kabanzi ezinhlelweni ezidinga ukumelana nokugqwala nokumelana nokushisa okuphezulu, njengamakhemikhali, i-petroleum, ukucubungula amandla ekhemisi, i-nuclear energy processing, i-nuclear

I-TP304 iyinsimbi engagqwali ye-austenitic yochungechunge lwe-300 yensimbi engagqwali futhi isetshenziswa kabanzi emikhakheni yezimboni, ikakhulukazi ezinhlelweni ezidinga ukumelana nokugqwala kanye nokumelana nezinga lokushisa eliphezulu. I-TP 304 insimbi engagqwali iqukethe u-18% we-chromium kanye ne-nickel engu-8%, eyinika ukumelana nokugqwala okuhle kanye nezakhiwo ezinhle zokusebenza. Ipayipi elishiselwe le-TP 304 insimbi engagqwali lisetshenziswa kakhulu embonini ukuthutha uketshezi, igesi kanye nesitimu, kanye nezinto zokwakha embonini yamakhemikhali, kaphethiloli, ekucubunguleni ukudla, ezimbonini zezemithi nezenuzi.
