316L-316Ti-316Hi Pipe Yesimbi isina Stainless

Yakagadzirirwa kutsungirira hukasha hwemakemikari mamiriro, iyo316 serieszvesimbi dzisina tsvina-dzinosanganisira316L, 316H, uye 316Ti{{0}inopa kupikisa kusingaite chloride corrosion uye oxidation.

Giredhi rega rega rinoshanda zvakasiyana zvekupisa kana zvekugadzira zvinodiwa, zvichipa mainjiniya kuchinjika pane ese ekugadziridza zvidyarwa, masisitimu emagetsi, uye nharaunda dzemugungwa.

• 316L:Yakaderera{{0}kabhoni musiyano unoderedza kunaya kwecarbide panguva yewelding.
• 316H:Yepamusoro{{0}kabhoni giredhi yakagadziridzwa kuti-simba retembiricha yakakwira uye kusapinda.
• 316Ti:Titanium-yakagadzikana shanduro inonakisa intergranular corrosion kudzivirira patembiricha yepamusoro.

The alloy's18% chromium uye 12% nickelnheyo inoumba yakagadzikana austenitic chimiro, nepomolybdenum (~ 2.0–3.0%)inowedzera gomba uye kusaita ngura mukutsemuka muchloride{{0}inotakura zvinobudisa nhau.

Titanium kana kuti inodzorwa kabhoni inogadziridza inobvumira kuita kwakaenderana-kungava mu cryogenic pombi kana superheater assemblies.

Key metallurgical zvakanakira:

• Yakanakisa kuramba kune acetic, phosphoric, uye sulfuric acids
• Kusadzivirirwa kwakanyanya kuchloride{{0}kukonzera kuparara kwecorrosion stress
• Yakagadzikana oxide firimu kuumbwa kusvika ku870℃(1600℃F)
• Yakasarudzika weld kutendeseka ine kushomeka kwekunzwa njodzi

Kuvepo kwe molybdenum uye chromium mukuenzanisa kwakaenzana kunovimbisa kupikisa kwepamusoro kune oxidation uye acid corrosion, zvichiita kuti aya alloys akwane kune ese maindasitiri uye ekuvaka maapplication.

Mechanical zvinoonekwa:

316L yakanakira maassembly akasungwa uye mapaipi e-cryogenic; 316H uye 316Ti zviri nani mutembiricha yakadzikama-nekukwira kuri kuita nani.

Kugadzirwa kwe316-yakatevedzana pombi dzesimbi dzisina simbi kunoda kunyatso kudzora kwesimbi kuchengetedza kusaita ngura uye kufanana kwemagetsi.

Kusiyana nekabhoni simbi, aya austenitic alloys anoda nzvimbo dzakachena dzekunyunguduka, kudzora tembiricha yakadzikama, uye inodzorwa kutonhora mitengo kudzivirira kunzwisiswa kana kukora zviyo.

Standard production flow:

• Vacuum kana Argon Furnace Melting:Inonatsa makemikari alloy uye inoderedza kusvibiswa kwenitrogen kana sarufa.
• Kuboora Kupisa uye Kurebesa:Inoshandura mabhii akasimba kuita makomba asina musono ane gwara rekuyerera kwezviyo zvekushingirira kwepamusoro.
• Cold Kudhirowa uye Kukura:Inowana chaiyo kushivirira, yakagadziridzwa concentricity, uye inosimudzira pamusoro kutsvedzerera.
• Solution Anealing:Inoitwa pakati pe1040 dhigirii uye 1120 dhigirii, ichiteverwa nekukurumidza mvura kana mhepo kudzimwa kunyungudutsa carbides uye kudzoreredza yakazara austenitic corrosion resistance.
• Pickling uye Passivation:Inobvisa maokisijeni uye kudzoreredza chromium{{0}rich passive film yakakosha kuti irambe yakasimba muacidic kana chloride{1}}yakapfuma nharaunda.

Welded pombi dzinogadzirwa uchishandisaGTAW (TIG)kanalaser weldingine zvigadziriso zvekuzadza zvakaenderana neyakagadzika kuumbwa (ER316L kana ER316Ti).

Post-weld solution annealing and polishing inogona kushandiswa kudzoreredza kusaita ngura mukugadzwa kwakakosha semakemikari nemapombi emishonga.

Inowanikwa muannealed, pickled, kanapolishedmapedza, mapaipi aya anopihwa kune zvese zvehutsanana nepressure-giredhi rekushandisa.

Kuongorora kwakadzama kunovimbisa kuti 316{1}}yakatevedzana pombi yesimbi isina simbi inochengetedza kugadzikana kwesimbi uye kusabuda kwekuita basa risati ratumirwa.

Nzira dzekuedza dzinoenderana neASTM A312, A999, uye zvinoenderanaASME SAzvinongedzo, zvinofukidza zvese zvinoparadza ne{0}zvisingaparadzi zvinhanho zvekuona.

Macheki emhando yepamusoro:

• Hydrostatic kana Eddy-Yazvino Kuedza:Inosimbisa kuvimbika kwemukati uye inoona kusaenderera mberi kwepamusoro.
• Tensile, Kuoma, uye Flattening Miedzo:Simbisa kuenderana kwemakina pamijenya yekugadzira.
• Intergranular Corrosion Test (ASTM A262 Dzidzira E):Inosimbisa kusadzivirirwa kune carbide kunaya, kunyanya ye316L uye 316Ti.
• Positive Material Identification (PMI):Inoita kuti alloy atevedzere Cr-Ni-Mo content.
• Visual uye Dimensional Inspection:Inoyera kutwasuka, kupera kwekupedzisira, uye kufana kwemadziro nemageji chaiwo.

A2: Sarudza 316L yekugadzira yakashongedzwa uko yakaderera kabhoni inobatsira kuderedza intergranular corrosion ngozi.

Q3: Ndeipi 316H Stainless simbi pombi inosarudzwa?

A3: Sarudza 316H yekukwira-tembiricha sevhisi uko kabhoni yakakwira inonatsa kusimba.

Q4: Ndirini pandinofanira kushandisa 316Ti simbi isina tsvina pombi panzvimbo ye316L?

Q4: Ndirini pandinofanira kushandisa 316Ti simbi isina tsvina pombi panzvimbo ye316L?
