A: Inconel 625 nwere nickel dị elu (58% nkeji vs 38-46%), molybdenum dị elu (8-10% vs 2.5-3.5%), ma nwee niobium (3.15-4.15%). O nwere ike dị elu karịa (415 MPa mmepụta vs 240 MPa), iguzogide pitting dị elu karịa (PREN 45-50 vs 30-35), na ikike okpomọkụ dị elu karịa (980°C vs 550°C). Incoloy 825 dị ọnụ ala karịa ma zuru oke maka ọtụtụ ọrụ acid; A na-eji Inconel 625 maka ọnọdụ kachasị njọ (mmiri oké osimiri dị elu, ọrụ gbara ụka nwere H₂S dị elu, asịd okpomọkụ dị elu).
A: Ọ dị mkpa ka a na-eme ka ọkpọkọ Inconel 625 sie ike?
A: Ee, dịka ASTM B705 si kwuo. Alloy 625 nwere ike ịmepụta usoro intermetallic na-emebi emebi (delta, Laves) na mpaghara okpomọkụ metụtara ma ọ bụrụ na oyi adịghị nwayọ. Ịkwụsị ngwọta na 1120-1180°C wee gwụchaa mmiri na-agbaze usoro ndị a ma weghachi nguzogide nchara na ductility. Womic na-arụ ọrụ nrụzi zuru oke na paịpụ niile ejiri welded Alloy 625 mee.
A: Enwere ike iji Inconel 625 mee ihe n'ime mmiri oké osimiri?
A: Ee, Inconel 625 nwere ezigbo iguzogide nsị na mmebi oghere n'ime mmiri oké osimiri, ọbụlagodi n'ọnọdụ okpomọkụ dị elu (okpomọkụ olulu dị oke njọ karịa 100°C). A na-ejikarị ya eme ihe maka mgbapụta mmiri oké osimiri, sistemụ mmiri ọkụ, na ihe ndị dị n'okpuru mmiri n'ime ubi miri emi. Maka ọtụtụ ojiji mmiri oké osimiri, super duplex 2205 ma ọ bụ 2507 zuru oke; Alloy 625 dị maka ọnọdụ kachasị njọ (okpomọkụ dị elu, chlorination dị elu, ọrụ gbara ụka yana mmiri oké osimiri).
Q: Inconel 625 ọ dị mma maka ọrụ mmiri ara ehi (H₂S)?
A: Ee. Alloy 625 ruru eru dịka NACE MR0175/ISO 15156 si kwuo maka ọrụ gbara ụka nwere nrụgide H₂S nke ruru ogwe 10 (150 psi) na karịa, na-enweghị oke ike (ọ bụrụhaala na ejiri ngwọta ahụ mee ihe nke ọma). A na-akọwakarị ya maka ọkpọkọ mmiri dị n'okpuru ala, eriri mmiri dị n'okpuru mmiri, na ihe ndị dị n'elu olulu mmiri n'ime ubi gbara ụka nke ukwuu ebe duplex na super duplex ezughị oke.
Q: Kedu okpomọkụ ọrụ kachasị elu maka Inconel 625?
A: Inconel 625 nwere ezigbo iguzogide oxidation ruo 980°C (1800°F) n'ikuku. Maka ngwa ndị nwere nrụgide, a na-enye nrụgide ndị a na-ekwe ka ha dị na Nkebi nke VIII nke ASME ruo 815°C (1500°F). Maka okpomọkụ dị elu (karịa 980°C), enwere ike ịchọ alloys ndị ọzọ dị ka Inconel 600, 601, ma ọ bụ 617.
Q: Kedu ihe eji eme ihe mkpuchi ọkụ ka akwadoro maka Inconel 625?
A: AWS A5.14 ERNiCrMo-3 (Inconel 625 ihe ndochi) bụ ihe ndochi dabara adaba maka ịgbado ọkụ N06625. Maka ijikọ Alloy 625 na alloys ndị ọzọ (dịka ọmụmaatụ, carbon steel, duplex), a na-ejikarị ERNiCrMo-3 eme ihe. Womic na-eji ERNiCrMo-3 maka usoro EFW.
Q: Kedu oge ndu nkịtị maka ọkpọkọ ọkpọkọ UNS N06625?
A: Ụbọchị 90-120 maka ERW (obere ruo ọkara dayameta), ụbọchị 120-150 maka EFW/LSAW (nnukwu dayameta). Oge ndu dị ogologo karịa nke ígwè anaghị agba nchara n'ihi na a na-emepụta eriri/efere alloy n'obere ọnụọgụ yana oge ndu igwe ogologo (ọtụtụ mgbe izu 16-24). Nnyocha nke ndị ọzọ na-agbakwụnye ụbọchị 14-21.
Ajụjụ: Kedu ka esi egbochi mmetọ ígwè na paịpụ Alloy 625?
A: Womic na-eji ngwa eji ígwè anaghị agba nchara arụ ọrụ, ihe e ji atụgharị ihe, na ihe e ji echekwa ihe maka paịpụ nickel niile. A machibidoro ngwaọrụ ígwè carbon. A na-etinye paịpụ n'ime plastik ozugbo e mechara pịpịa ya. Maka ngwa dị mkpa n'ụsọ oké osimiri na ngwa nuklia, anyị na-enye asambodo njikwa mmetọ.

Ngụkọta:Mita 6,500, ihe dị ka tọn 97
Nkọwapụta:Ngwakọta ASTM B705 UNS N06625 a gwakọtara agwakọta ma gwerie ya, nsọtụ ya a beveled (bevel dị elu maka ịgbado ọkụ n'okpuru mmiri). Nnwale Hydrostatic na nrụgide imewe 1.5 × (nhazi 35 MPa). 100% UT (usoro nhazi) gbakwunyere 100% RT maka njikọta niile (stringent). PMI na paịpụ ọ bụla. Nnwale nchara dị mkpa dịka Usoro ASTM G48 A si dị (6% FeCl₃, 72h na 40°C) - enweghị olulu mmiri. Nrubeisi NACE MR0175 maka ọrụ utoojoo (H₂S akụkụ nrụgide 0.5 bar). Mmetụta Charpy na -46°C (spec 27J, enwetara 120-180J). Ike kachasị 30 HRC (enweta 22-26 HRC). Nlele zuru oke site na ingot ruo na paịpụ emechara. Nnyocha nke atọ site na DNV Brazil.
Ngwa:Mkpọda jumper dị n'okpuru mmiri na njikọ mmiri na-agafe agafe n'ime ubi tupu nnu (Santos Basin). Mmiri ahụ e mepụtara nwere H₂S (nrụgide akụkụ 0.5 bar), CO₂, na mmiri chloride dị elu (100,000 ppm Cl⁻) na 80°C. A chọrọ alloy na-eguzogide corrosion (CRA). A họọrọ Alloy 625 maka iguzogide pitting, SSC, na HIC n'ebe a na-eme ihe ike.
Ihe Ịma Aka na Ngwọta Teknụzụ:
1. Ọrụ dị oke njọ (H₂S dị elu + chloride dị elu + okpomọkụ dị elu)– Nchikota nke H₂S (0.5 bar) na 100,000 ppm Cl⁻ na 80°C karịrị ike nke super duplex. Alloy 625 nke nwere oke nickel na molybdenum ya na-eguzogide mgbawa nrụgide pitting na sulfide. Womic mere nnwale HIC na SSC dịka NACE TM0284 na TM0177 si dị. HIC: CLR 0%, CTR 0%, CSR 0%. SSC (Usoro A, 720h na 90% SMYS na 0.5 bar H₂S): enweghị mgbawa.
2. Asambodo ịgbado ọkụ n'okpuru mmiri maka imepụta jumper– Ndị na-agbagharị ihe ndị a chọrọ ịgbado ọkụ ubi (paịpụ ruo flange) site na iji usoro ịgbado ọkụ dịpụrụ adịpụ (hyperbaric). Womic nyere kupọọnu ịgbado ọkụ 30 yana WPS akwadoro site na iji ihe nzacha GTAW, ERNiCrMo-3, kpoo ọkụ tupu oge eruo 10-20°C, interpass ≤ 120°C, ntinye okpomọkụ ≤ 1.2 kJ/mm. Kupọọnu ndị ahụ gafere RT, PT, tensile, na Charpy na -46°C (weld 110-160J). Onye ọrụ ịgbado ọkụ nke onye ahịa mere nke ọma.
3. Ovality siri ike maka njikọ dị n'okpuru mmiri– Jumpers dị n'okpuru mmiri na-eji njikọ igwe nke chọrọ ovality ≤ 0.2% nke OD. Usoro ERW ziri ezi nke Womic jiri mee ihe na-esote eserese oyi na nhazi roller. A tụrụ ovality ikpeazụ: paịpụ 4″ 0.12-0.18%, paịpụ 6″ 0.10-0.15%, paịpụ 2″ 0.08-0.12%. Ihe niile gafere.
4. Nnwale ire ere na oke okpomọkụ (40°C na FeCl₃)– Usoro G48 Ọkọlọtọ A bụ 22°C; onye ahịa chọrọ 40°C (ka njọ karịa). Womic mere nnwale pitting na 40°C ruo awa 72 - enweghị pitting na ihe nlele ọ bụla (ígwè ntọala ma ọ bụ weld). E gosipụtara na iguzogide pitting metal ahụ bụ otu ihe ahụ na base metal.
5. Ịchọpụta site na ingot ruo na ọkpọkọ emechara– Ngwa ndị dị n'okpuru mmiri chọrọ nleba anya zuru oke nke ihe. Womic nyere nọmba paịpụ pụrụ iche ma soro paịpụ ọ bụla site na nọmba okpomọkụ ruo na nyocha ikpeazụ. Ngwugwu akwụkwọ gụnyere peeji 1,200 nke MTCs, akụkọ NDT, na nsonaazụ ule nchara. DNV nyochachara ma kwado ya.
6. Lọjistik gaa na ụlọ ọrụ mmepụta ihe na Santos Basin– E si Shanghai bufee paịpụ gaa Rio de Janeiro, wee gaa n'ebe a na-emepụta ihe na Niterói. DNV hụrụ ka e si ebu ibu. E bufere tọn 97 niile na mbupu atọ n'ime ọnwa ise. E bufere mbupu ikpeazụ ngwa ngwa iji mezuo oge ọrụ (ibu ụgbọelu maka tọn 10 nke paịpụ 2″).
Nsonaazụ:E tinyere ihe mkpuchi mmiri dị n'okpuru mmiri n'ime nkeji mbụ nke afọ 2024. Mgbe ọnwa iri na abụọ nke mmepụta gasịrị, akọpụtabeghị mmebi ma ọ bụ mgbawa ọ bụla. Onye ọrụ ahụ ahaziela ihe nlereanya na Alloy 625 maka ihe mkpuchi mmiri niile dị n'ubi tupu nnu. Womic Steel bụzi onye na-ebubata ihe ruru eru maka ihe achọrọ maka paịpụ CRA nke onye ọrụ a.
