Mibvunzo Inowanzo bvunzwa (Mibvunzo Inowanzo bvunzwa) - ASTM B705 UNS N06625 Welded Pipe

Mubvunzo: Musiyano uripo pakati peInconel 625 (N06625) neIncoloy 825 (N08825) ndeupi?
A: Inconel 625 ine nickel yakakwira (58% min vs 38-46%), molybdenum yakakwira (8-10% vs 2.5-3.5%), uye ine niobium (3.15-4.15%). Ine simba rakakwirira (415 MPa yield vs 240 MPa), inodzivirira makomba zvakanyanya (PREN 45-50 vs 30-35), uye inokwanisa kupisa zvakanyanya (980°C vs 550°C). Incoloy 825 inochengetedza mari uye yakakwana kune akawanda maasidhi; Inconel 625 inoshandiswa mumamiriro ezvinhu akaipisisa (mvura yegungwa inopisa zvakanyanya, sevhisi yakaoma ine H₂S yakakwira, acids inopisa zvakanyanya).

Mubvunzo: Kuisa mvura inonyungudutswa kunosungirwa here papombi yeInconel 625 yakasungirirwa?
A: Ehe, zvichienderana neASTM B705. Alloy 625 inogona kugadzira zvikamu zvinokuvadza zvepakati pesimbi (delta, Laves) munzvimbo ine kupisa kana kutonhora kuchinonoka. Kunyungudutsa kwemvura pa1120-1180°C kunoteverwa newater quench kunonyungudutsa zvikamu izvi uye kunodzoreredza kuramba kwengura uye ductility. Womic inoita annealing yakazara yemvura pamapombi ese eAlloy 625 akasungirirwa.

Mubvunzo: Inconel 625 inogona kushandiswa mumvura yegungwa here?
A: Ehe, Inconel 625 inodzivirira ngura kubva mugomba kusvika mumipata mumvura yegungwa, kunyangwe pakupisa kwakanyanya (kupisa kwakanyanya kwegomba kusvika pa100°C). Inowanzo shandiswa pamapombi ekusimudza mvura yegungwa, masisitimu emvura yemoto, uye zvikamu zvepasi pegungwa munzvimbo dzakadzika. Kune akawanda mashandisirwo emvura yegungwa, super duplex 2205 kana 2507 yakakwana; Alloy 625 yakachengeterwa mamiriro ekunze anotyisa (kupisa kwakanyanya, chlorination yakakwira, sevhisi yakaoma pamwe chete nemvura yegungwa).

Mubvunzo: Inconel 625 yakakodzera kushandiswa pakugadzira sour service (H₂S) here?
A: Ehe. Alloy 625 inokodzera zvichienderana neNACE MR0175/ISO 15156 yekushandira sour service ine H₂S partial pressures inosvika 10 bar (150 psi) zvichikwira, isina miganhu yekuomarara (chero bedzi mhinduro yakanyungudutswa zvakanaka). Inowanzo tsanangurwa kune downhole tubes, subsea flowlines, uye wellhead components muminda ine sour yakawanda uko duplex ne super duplex zvisina kukwana.

Mubvunzo: Ndeipi tembiricha yepamusoro yebasa reInconel 625?
A: Inconel 625 ine simba rakanaka rekudzivirira oxidation kusvika 980°C (1800°F) mumhepo. Pakushandisa zvine simba, kumanikidzwa kunobvumirwa paASME Section VIII kunopiwa kusvika 815°C (1500°F). Pakupisa kwakanyanya (kupfuura 980°C), mamwe ma alloys akadai seInconel 600, 601, kana 617 anogona kudiwa.

Mubvunzo: Ndeipi simbi yekuzadza welding inokurudzirwa paInconel 625?
A: AWS A5.14 ERNiCrMo-3 (Inconel 625 filler) ndiyo filler inoenderana ne welding N06625. Pakubatanidza Alloy 625 kune mamwe ma alloys (semuenzaniso, carbon steel, duplex), ERNiCrMo-3 inowanzoshandiswawo. Womic inoshandisa ERNiCrMo-3 pakuita EFW.

Q: Ndeipi nguva yakajairika yekuendesa pombi yeUNS N06625 yakasungirirwa?
A: Mazuva 90-120 eERW (dhayamita diki kusvika pakati), mazuva 120-150 eEFW/LSAW (dhayamita hombe). Nguva dzemutobvu dzakareba zvakanyanya kupfuura dzesimbi dzisina ngura nekuti chidimbu chemutobvu/plate chinogadzirwa muhuwandu hudiki nenguva refu dzemutobvu (kazhinji mavhiki 16-24). Kuongorora kwechitatu kunowedzera mazuva 14-21.

Mubvunzo: Munodzivirira sei kusvibiswa kwesimbi pamapaipi eAlloy 625?
A: Womic inoshandisa maturusi ekubata simbi isina ngura, maroller, uye ma racks ekuchengetera mapombi ese e nickel alloy. Maturusi esimbi yekabhoni haabvumirwi. Mapombi anoputirwa mupurasitiki mushure mekubikwa. Kune zvakakosha pakushandiswa kwemvura nenyukireya, tinopa chitupa chekudzivirira kusvibiswa.

Chirevo chePurojekiti - Mutsetse wemvura yakadzika pasi pegungwa wemunda weH₂S/High Chloride (Brazil)

Nyika:Brazil (Santos Basin, munda wemunyu usati watanga, kudzika kwemvura 2200m)
Standard & Giredhi:ASTM B705 UNS N06625 (Inconel 625) – pombi yakaputirwa (yakagadzirwa neAlloy 625, kwete alloy yakazara yepurojekiti iyi – asi isu tinopa pombi yakazara alloy yemajumpers) – purojekiti chaiyo: majumper epasi pegungwa anoshandisa N06625 isina musono asi tinoshandisa pombi yakasungirirwa. Kugadzirisa: purojekiti inoshandisa N06625 yakasungirirwa yemajumpers madiki ane dhayamita (4″ uye 6″).
Zviyero & Huwandu:

● OD 114.3mm (4″) × Purogiramu 80S (8.56mm WT) – 2,000 metres (anenge matani 25) – Maitiro eERW (inodhonzwa inotonhora mushure mekusveta kuti ikwanise kushivirira)

● OD 168.3mm (6″) × Purogiramu 80S (10.97mm WT) – 1,500 metres (anenge matani 38) – Maitiro eERW

● OD 60.3mm (2″) × Purogiramu XXS (11.07mm WIT) – 3,000 metres (anenge matani 34) – Maitiro eERW
Huwandu:Mamita 6,500, anenge matani 97

Magadzirirwo:ASTM B705 UNS N06625 mhinduro yakanyungudutswa uye yakakangwa, yakachekwa (bevel yepamusoro yekuwelding pasi pegungwa). Kuedza kwemvura pa1.5× dhizaini yekumanikidza (dhizaini 35 MPa). 100% UT (phased array) pamwe ne100% RT yewelds dzese (dzakasimba). PMI papombi yega yega. Kuedzwa kwekuora kunosungirwa paASTM G48 Nzira A (6% FeCl₃, 72h pa40°C) - hapana gomba. Kutevedzera NACE MR0175 kwekushandira sour (H₂S chikamu chekumanikidzwa 0.5 bar). Charpy impact pa -46°C (spec 27J, yakawanikwa 120-180J). Kuoma kwakanyanya 30 HRC (yakawanikwa 22-26 HRC). Kugona kuteverwa zvizere kubva kuingot kuenda kupombi yakapedzwa. Kuongorora kwechitatu-bato neDNV Brazil.

Kushandiswa:Mapombi epasi pegungwa anodhonza mvura uye zvinobatanidzwa mumutsara wemvura mumunda une munyu usati waiswa (Santos Basin). Mvura inogadzirwa ine H₂S (0.5 bar partial pressure), CO₂, uye mvura ine chloride formation (100,000 ppm Cl⁻) pa80°C. Chidimbu chinodzivirira ngura (CRA) chinodiwa. Chidimbu 625 chakasarudzwa nekuda kwekudzivirira kwayo kugomba, SSC, uye HIC munzvimbo iyi ine hukasha.

Matambudziko ehunyanzvi nemhinduro:

1. Basa rakanyanya kuoma (H₂S yakakwira + machloride akakwira + tembiricha yakakwira)– Musanganiswa weH₂S (0.5 bar) uye 100,000 ppm Cl⁻ pa80°C haugoneke se super duplex. Alloy 625 ine nickel ne molybdenum yakawanda inodzivirira kupwanyika kwegomba uye sulfide stress. Womic yakaita bvunzo dzeHIC neSSC zvichienderana neNACE TM0284 neTM0177. HIC: CLR 0%, CTR 0%, CSR 0%. SSC (Method A, 720h pa90% SMYS mu0.5 bar H₂S): hapana kupwanyika.

2. Chitupa chekushongedza pasi pegungwa chekugadzira majumper– Majumpers aya anoda ma "field welds" (pipe to flange) achishandisa nzira dzekusveta dziri kure (hyperbaric). Womic yakapa makuponi makumi matatu e "weld" pamwe neWPS inokurudzirwa uchishandisa GTAW, ERNiCrMo-3 filler, preheat 10-20°C, interpass ≤ 120°C, heat input ≤ 1.2 kJ/mm. Makuponi akapfuura RT, PT, tensile, uye Charpy pa -46°C (weld 110-160J). Kontrakita we "weld" wemutengi ndiye akakwanisa kuita izvi.

3. Kureba kwakasimba kwezvinobatanidza zvepasi pegungwa– Majumper epasi pegungwa anoshandisa michina inosanganisa denderedzwa inoda ovality ≤ 0.2% yeOD. Womic yakashandisa nzira yeERW chaiyo ichiteverwa nekudhirowa kunotonhora uye kutwasanudza maroller. Ovality yekupedzisira yakayerwa: 4″ pombi 0.12-0.18%, 6″ pombi 0.10-0.15%, 2″ pombi 0.08-0.12%. Zvese zvakapasa.

4. Kuedzwa kwengura pakupisa kwakakwira (40°C muFeCl₃)– Nzira yeG48 A standard i22°C; mutengi aidiwa 40°C (yakanyanya kuoma). Vakadzi vakaita bvunzo yekuisa makomba pa40°C kwemaawa makumi manomwe nemaviri – hapana kuisa makomba pane chero sampuli (simbi yesimbi kana weld). Kudzivirira makomba kwesimbi yeweld kwakasimbiswa kuti kwakaenzana nesimbi yesimbi yesimbi.

5. Kukwanisa kuteverwa kubva ku ingot kuenda kupombi yakapedzwa– Mashandisirwo epasi pegungwa anoda kuteverwa kwakazara kwezvinhu. Womic akapa nhamba dzemapaipi dzakasiyana uye akateedzera pombi yega yega kubva panhamba yekupisa kusvika pakuongororwa kwekupedzisira. Pakeji yemagwaro yaisanganisira mapeji 1,200 eMTCs, mishumo yeNDT, uye mhedzisiro yekuyedzwa kwekuora. DNV yakaongororwa uye yakatenderwa.

6. Kutakura zvinhu kuenda kuSantos Basin fabrication yard– Mapaipi akatumirwa kubva kuShanghai kuenda kuRio de Janeiro, ndokuzoendeswa kunzvimbo yekugadzira zvinhu muNiterói. DNV yakaona zvinhu zvichizadzwa. Matani ese 97 akatumirwa muzvikamu zvitatu mukati memwedzi mishanu. Kutumirwa kwekupedzisira kwakakurumidziswa kuti kusvike pakupera kwechirongwa (kutakura zvinhu nendege kwematani gumi emapaipi e2″).

Mhedzisiro:Majumper epasi pegungwa akaiswa muQ1 2024. Mushure memwedzi gumi nemiviri yekugadzira, hapana ngura kana kutsemuka kwataurwa. Mushandi weAlloy 625 akajairwa paAlloy 625 kune ese majumper ebasa rakaoma munzvimbo dzine munyu usati waiswa. Womic Steel ikozvino ndiyo mutengesi akakodzera wezvinodiwa zveCRA pombi yemushandi uyu.
