Alloy Profile n'omulimu gw'amakolero
Inconel 625, era emanyiddwa nga Nickel Alloy 625 oba UNS N06625, ye nickel-chromium-molybdenum-niobium alloy enywevu-solution–stronged ekoleddwa okukola emirimu awali okukulukuta n’ebbugumu erisukkiridde okubeera awamu. Kikuuma amaanyi ag’enjawulo, okuziyiza okuseeyeeya, n’obutebenkevu bw’okuwunyiriza okuva mu mbeera za cryogenic okutuuka ku diguli 1000 (1832 diguli F).
Ekika kino kikozesebwa nnyo mu byuma by’ennyanja, enkola z’okulongoosa eddagala, ebitundu ebifuga obucaafu, ebyuma ebikola ebyuma bya nukiriya, n’enkuŋŋaana z’omukka ogufuluma mu yingini z’ennyonyi-okukozesa nga obulungi bw’enzimba n’okufuga okukulukuta birina okukola mu ngeri y’emu. Bbalansi yaayo eya Ni-Cr-Mo-Nb ekola firimu ya okisayidi eyeewonya era n’enyigiriza okulumba okw’omu kitundu ne mu mbeera za asidi ne klorayidi-ezirimu.
Enteekateeka y’Eddagala n’Engeri y’Ebyuma
| Ekintu | % Ebanga | Enkola |
|---|---|---|
| Nickel (Ni) nga . | Okusinga oba okwenkana 58.0 | Matrix ya base; okukulukuta n’okutebenkera kw’ebbugumu |
| Chromium (Cr) nga . | 20.0–23.0 | Ekola passive oxide okusobola okufuga oxidation |
| Molibdenimu (Mo) . | 8.0–10.0 | Aziyiza okukulukuta kw’ebinnya n’enjatika |
| Nayiyobiyamu (Cb + Ta) . | 3.15–4.15 | Anyweza ekisengejjero ekigumu; kiziyiza okukyukakyuka kw’okuseeyeeya (creep deformation). |
| Ekyuma (Fe) . | Ekitono oba ekyenkana 5.0 | Alongoosa engeri z’okukola ebintu |
| Kaboni (C) . | Entono oba yenkana 0.10 | Afuga okutondebwa kwa carbide |
| Mn / Si / S | Ekitono oba ekyenkana 0.5 / 0.5 / 0.015 | Kuuma obuyonjo n’omutindo gwa weld |
Ekikolwa kya molybdenum ne niobium ekigatta kivaamu amaanyi amangi awatali kukaluba kwa nkuba, okusobozesa okukola okwangu n’okukola okutebenkevu mu kiseera ekiwanvu-okubeera mu bbugumu. Microstructure eno ekuuma empeke ennungi era eziyiza empeke-boundary embrittlement oluvannyuma lw’okuweta oba okufukirira.
Okwesigamizibwa kw’ebyuma wansi w’ebbugumu n’okunyigirizibwa
| Eby'obwa nannyini | Metric (eddakiika) . | Obwakabaka (eddakiika) . | Okunnyonnyola |
|---|---|---|---|
| Amaanyi g’okusika | 827 MPa | 120 ksi | Akuuma obulungi okutuuka ku diguli 870 |
| Amaanyi g’amakungula (0.2 %) . | 414 MPa | 60 ksi | Aziyiza okukyukakyuka wansi w’omugugu |
| Okuwanvuwa | Okusinga oba okwenkana 30 % . | Okusinga oba okwenkana 30 % . | Ductility ennungi ennyo oluvannyuma-okubikkulwa |
| Obukaluba | Entono oba yenkana 95 HRB | Entono oba yenkana 95 HRB | Awa obusobozi bw’ebyuma n’okukola obulungi |
Mu mbeera z’obuweereza obw’enzirukanya, Inconel 625 ekuuma amaanyi g’obukoowu n’obutebenkevu bw’ebipimo n’okufiirwa okutono mu kufuga oxidation.
Enkola y’okukola n’okulongoosa mu bbugumu
Payipu ne ttanka bikolebwa nga biyita mu kufulumya okwokya oba okusika mu nnyonta n’oluvannyuma solution annealed ku 1090–1150℃(1995–2100℃F) ne bigobererwa okuzikizibwa amangu okuzzaawo okuziyiza okukulukuta. Ebika ebiwelded bikolebwa mu nkola ya TIG oba plasma wansi w’okuziyiza ggaasi etali ya maanyi.
Okukola obulungi n’okugerageranya obunene mu nnyogovu bikuuma ekisengejjero ekimu, ate nga okusiika n’okufukirira okumasamasa biddamu okukola firimu y’okungulu eya Cr2O3 ekuuma. Okukola n’okukebera bigobereraASTM B444, B705, ne B704emitendera.
Okuziyiza okukulukuta mu mikutu gyonna
Alloy eno ekola emirimu ebiri-nickel-chromium oxide film for oxidizing conditions ne molybdenum-niobium reinforcement okukendeeza ku butonde-giwa obutebenkevu bwa kemiko obugazi:
- Amazzi g’ennyanja ne chlorides:Eziyiza okuzimba ebinnya, enjatika, n’okunyigirizibwa-okukutuka kw’okukulukuta.
- Asidi ezikola omukka (nayitiriki, chromic): .Chromium akuuma okunywerera kwa oxide ku bbugumu.
- Asidi ezikendeeza (hydrochloric, phosphoric): .Molybdenum aziyiza okulumba mu kitundu.
- Omukka omukaawa (H2S): .Stable against sulfide stress cracking ku mpeereza ya mafuta ne ggaasi.
- Okwokya okw’ebbugumu eringi-:Egumira okukutuka n'okufiirwa ebyuma okutuuka ku diguli 1000 .
Dimensional Range n’okugabira ebintu
| Okuwandiika | Ebweru Diameter | Obugumu bwa Bbugwe | Obuwanvu | Okunnyonnyola |
|---|---|---|---|---|
| Payipu Etaliiko Musono | 6–610 mm | 1–50 mm | Okutuuka ku mmita 12 | ASTM B444 / ASME SB444 |
| Payipu Ekoleddwa mu Welded | 25–1200 mm | 1.5–60 mm | Okutuuka ku mmita 12 | ASTM B705 / ASME SB705 |
| Tube (Ekiwanyisiganya ebbugumu / Ekikozesebwa) . | 6–76 mm | 0.8–10 mm | Coil / Egolokofu | ASTM B704 / ASME SB704 |
Okumaliriza okunywevu-okugumiikiriza kuliwo ku bikozesebwa n’enkuŋŋaana z’okuwanyisiganya ebbugumu ezeetaaga okutuuka obulungi n’okumaliriza kungulu.
Okugezesa, Okukakasa, n’Okukakasa Omutindo
Ebintu byonna bigezesebwa buli...ASTM B829ku butuukirivu obutali-obusaanyaawo n'obutuufu bw'ebipimo.
Okukebera okwa bulijjo kuliko okwekenneenya amazzi oba amaloboozi amangi, okukakasa PMI okuzuula ebirimu nickel, n’okugezesa okukulukuta wakati w’obutundutundu (ASTM G28 Method A/C).
Octal Pipe egaba ebikozesebwa nga...EN 10204 3.1 / 3.2 MTC, okulondoola okujjuvu, n'enkola z'okukebera ez'ekibiina eky'okusatu- (BV, SGS, TUV).
Okussa mu nkola amakolero n’okuwagira pulojekiti
Inconel 625 ekola ku bikozesebwa ebikulu omuli payipu eziri ku nnyanja mu mubisi gwa chloride, ebitundu ebifulumya omukka mu bbanga, amaato agaddamu okulongoosa nukiriya, ebyuma ebiggya omunnyo, n’ebyuma ebirongoosa obucaafu.
Octal Pipe egaba eby’okugonjoola eby’okugaba mu ngeri ya yinginiya nga zirina ebisaanyizo by’okuweta, okukwasaganya NDE, n’ebiwandiiko eby’ekikugu ebituukira ddala ku pulojekiti za EPC ne amaanyi. Okufuga enkola okutambula obulungi kukakasa okukola emirimu gy’ebyuma n’okukulukuta egy’okuddiŋŋana mu buli kibinja ky’ebbugumu.
