Nickel Alloy Casing thiab Ntau Cov Yeeb Nkab: OCTG CRA Qib

Nickel alloy casing thiab ntau lawm tubing

Nickel alloy casing thiab tubing yog Ni-based CRA (corrosion resistant alloy) OCTG cov khoom siv hauv cov roj thiab roj qhov dej uas cov pa roj carbon steel lossis cov qib OCTG qib tsis muaj kev ntseeg txaus tiv thaiv corrosion thiab corrosion. tawg. Tsis yog tsuas yog tso siab rau kev xeb dhau, cov khoom siv no siv cov qib siab-alloy npib tsib xee-raws li qib xws li N08028, N08535, N08135, N08825 thiab N06985 raws li API 5CRA muab logic, nrog N09925 thiab N07718 xaiv cov ntawv thov. hnub nyoog hardening nyob rau hauv API 6ACRA.

Cov qib no raug xaiv rau cov xwm txheej zoo nrog H2S, CO2, chlorides, siab salinity tsim dej thiab siab kub, qhov chaw tiv thaiv sulfide stress cracking (SSC), kev nyuaj siab corrosion cracking (SCC), thiab localized corrosion, raws li zoo raws li kev tiv thaiv ntawm kev twb kev txuas tsis ua hauj lwm, yuav tsum tau kev txhawb los ntawm cov hlau txoj kev, kev xa khoom, txheej txheem tsim thiab kuaj cov ntaub ntawv pov thawj corrosion.

 

Nickel Alloy OCTG Qib Muaj

Rau API 5CRA txoj hauv kev, Ni-based alloys seem suav nrog BG2830 / UNS N08028, BG2532 / UNS N08535, BG2235 / UNS N08135, BG2142 / UNS N08825, thiab BG2250 / UNS N06985 casing, tag nrho lub cev, thiab lub cev. kev twb kev txuas lub txiv mis hauv 110/125 ksi chav kawm nrog txias hardened tus me nyuam mob. Rau API 6ACRA txoj kev, N09925 yog teev nyob rau hauv 110 ksi lub hnub nyoog hardened, thaum N07718 muaj nyob rau hauv 120 thiab 140 ksi hnub nyoog hardened nyob rau hauv bar los yog tubular daim ntawv.

Ib txoj hauv kev ua tau zoo yog cais tsev neeg qib rau hauv peb txheej xaiv. Thawj txheej yog CRA ntau lawm tubing thiab casing resistant rau acidic thiab chloride media nyob rau hauv ntau yam N08028, N08535, N08135, N08825 thiab N06985, rau cov qhov dej uas xav tau nruj corrosion tswj dua li tsawg alloy OCTG los yog txheem stainless hlau muaj peev xwm muab. Qhov thib ob txheej yog cov hnub nyoog-hardened txoj kev xws li N09925 thiab N07718, qhov twg lub zog siab dua thiab xav tau kev pab cuam ntau dua ntawm cov khoom siv yog ib feem ntawm cov lus qhia. Cov txheej thib peb yog qhov kev sib txuas thiab tso tawm pob, vim tias cov hlua hlau uas muaj txiaj ntsig zoo tseem tuaj yeem ua tsis tau ntawm cov xov, lub xub pwg nyom lossis tso tawm theem yog tias machining thiab kev soj ntsuam xyuas tsis zoo.

Cov txheej txheem tswj hwm Nickel Alloy Casing thiab cov yeeb nkab ntau lawm

Txoj kev tsim khoom muab rau cov nickel alloy casing thiab cov yeeb nkab ntau lawm yog ua raws li ISO 13680 / API Spec 5CRA, PSL-1 thiab PSL-2, nrog rau kev siv NACE MR0175 / ISO 15156-3 thiab API 5CT / ISO 11960. Qhov kev tswj hwm no tseem ceeb heev vim tias qhov loj me ntawm Nickel alloy tsis yog xaiv rau OCT, tab sis nws tseem ceeb heev vim tias qhov loj me ntawm cov nickel alloy tsis yog rau OCT. kev pabcuam hauv acidic media, chloride fluids, thiab xav tau qhov chaw downhole, qhov twg cov ntaub ntawv tsim nyog thiab tso tawm cov ntaub ntawv yuav tsum tau meej.

Hauv kev tshuaj xyuas qhov project, cov qauv no txhais tau li cas cov khoom tau teev tseg, tsim, tshuaj xyuas thiab txais kev pabcuam downhole corrosive. Nickel alloy casing thiab cov tubing ntau lawm yuav tsum raug soj ntsuam cais los ntawm cov pa OCTG, thiab tseem cais los ntawm cov tsho los yog kab CRA tubing siv rau saum npoo los yog hauv cov kav dej, vim tias cov khoom tsim, kev pabcuam kev pabcuam, thiab kev tsim nyog tau sib txawv.

OCTG hauv nickel alloy yog kim vim li cas. Cov kev xa khoom steel zeb raug qhia tias qhov no tsis yog kev yuav khoom yooj yim ntawm cov yeeb nkab seamless. Nyob ntawm qib, cov txheej txheem yuav suav nrog EAF + AOD + LF melting, ingot casting, ESR qhov yuav tsum tau, forged billet, kub extrusion los yog kub punch dov, solubilization annealing, txias dov los yog txias kos duab thiab zaum kawg soj ntsuam. Rau N09925 thiab N07718, txoj kev txuas mus rau VIM ntxiv rau ESR lossis VAR, ua raws li kev ua haujlwm kub lossis bar forging, kev daws teeb meem annealing, hnub nyoog hardening thiab tshuaj xyuas lossis machining. Cov txheej txheem ntawd yog ib qho ntawm cov nqi tsav tsheb tiag tiag tom qab muab cov nickel alloy casing thiab cov tubing ntau lawm.

Cov ntaub ntawv txheej txheem steel zeb kuj piav qhia lub hom phiaj ntawm txoj kev ntawd. Kev xyaum ua kom zoo dua qub yog siv los tswj chemistry thiab purity, txo kev sib cais, thiab khaws cov khoom tsim kev puas tsuaj. Kub extrusion thiab txias dov yog siv los txhim kho microstructural uniformity thiab seem raug.

Thib peb SCC Test Results

 

Koj tuaj yeem tshuaj xyuas SCC cov txiaj ntsig raws li cov kev pabcuam simulated hauv PDF hauv qab no: SCC cov txiaj ntsig hauv cov kev pabcuam simulated

Cov ntaub ntawv steelmaker suav nrog cov neeg thib peb SCC cov txiaj ntsig hauv kev simulated kev pabcuam rau N08028 thiab N08535, nrog rau tag nrho cov txiaj ntsig tau tshaj tawm tias "tsis muaj qhov tawg tom qab 720 teev." Cov lus suav nrog cov qhov rais tiag tiag es tsis yog cov lus qhia dav dav, ua rau nws muaj txiaj ntsig zoo rau ob tus neeg yuav khoom thiab cov kws tshuaj xyuas.

Piv txwv ntawm cov khoom siv kuaj muaj xws li N08535 ntawm 3-1 / 2″ 9.2 PPF nyob rau hauv cov xwm txheej ntawm ntau tshaj 20,000 ppm chlorides ntawm 90Â℃thiab 840 MPa rau 720 teev tsis muaj kab nrib pleb, thiab N08028 ntawm 7″ 26 PPF ntawm 0ppm ntawm chloride ntawm 0. 120º℃thiab 872 MPa rau 720 teev tsis muaj kab nrib pleb.

Qhov twg nickel Alloy casing thiab cov yeeb nkab ntau lawm yog siv

Nickel alloy casing thiab cov tubing ntau lawm feem ntau yog siv nyob rau hauv qhov chaw zoo uas H2S, CO2, chlorides thiab kev pabcuam kub ua rau cov pa OCTG tsis tshua muaj kev ntseeg siab tshaj nws txoj kev xav tau lub neej.

Cov ntawv thov muaj xws li cov qhov dej qaub qaub, cov dej salinity ntau los yog ua tiav ib puag ncig, thiab cov seem tseem ceeb hauv qhov dej uas tus nqi ntawm kev cuam tshuam kev ua haujlwm lossis kev ncua sij hawm ntau dua li tus nqi them rau qib siab OCTG CRA txoj kev. Hauv cov xwm txheej no, kev xaiv cov khoom siv yog tswj hwm los ntawm kev ncaj ncees mus ntev, kev tiv thaiv corrosion thiab kev cuam tshuam kev pheej hmoo, tsis yog kev sib piv tus nqi pib xwb.

Kev sib txuas ncaj ncees, kev tshuaj xyuas thiab cov ntaub ntawv pov thawj

Rau nickel alloy casing thiab ntau lawm tubing, alloy kev ua tau zoo ib leeg tsis txaus yog tias txoj kev sib txuas tsis raug tswj tau zoo. Txoj hauv kev muaj nyob hauv lub Hoobkas suav nrog qhov hwm BGT3 kev sib txuas, nrog rau kev ua kom zoo tshaj qhov sib khi geometry, tswj kev sib dhos tus cwj pwm thiab kev ntsuas kub ntawm API RP 5C5: 2017. Rov ua dua kev ua tub rog thiab kev tshem riam phom kuj yog ib feem ntawm kev sib txuas tus nqi rau kev thov OCTG kev pabcuam.

Kev tshuaj xyuas thiab tso tawm yuav tsum ua raws li cov ntaub ntawv pov thawj tseeb. Lub Hoobkas muaj peev xwm muaj xws li NDT, kuaj hydrostatic, kuaj tensile, kuaj hardness, kuaj metallurgical thiab cov ntaub ntawv soj ntsuam sib raug. Kev txiav txim tuaj yeem raug tso tawm nrog traceable marking, cam khwb cia thiab ntau cov cim, MTC, thiab lub Hoobkas lossis cov ntaub ntawv thib peb xav tau los ntawm qhov project.
