Daim ntawv thov ntawm Titanium Alloy hauv Petrochemical Kev Lag Luam

Txij li thaum nrhiav tau ntawm titanium hlau, kev lag luam tshuaj tau siv ntau tshaj plaws. Hauv 12 xyoo dhau los, kev siv titanium hauv tsev hauv kev lag luam tshuaj tau tshaj 15, 000 tons hauv ib xyoos.
Titanium cia siab rau: titanium muaj zog dua thiab muaj peev xwm ua haujlwm ntau dua
Tsis txhob kwv yees tag nrho titanium alloy laum yeeb nkab, lub zog tshwj xeeb ntawm tus pas nrig, yog 3.5 npaug ntawm cov hlau tsis muaj steel, 1.3 npaug ntawm aluminium alloy, 1.6 npaug ntawm magnesium alloy, tib lub teeb thiab hnyav, tuaj yeem tiv taus ntau dua. thiab siab.
Nws lub zog tensile kuj tseem yog 1. , luv luv vojvoog qhov dej thiab lwm yam complex zoo tej yam kev mob.
Nyob rau hauv xyoo tas los no, txhawm rau txhim kho cov roj av rov qab, txo tus nqi ntawm cov roj thiab cov roj av, thiab txuas ntxiv kev txhim kho lub neej ntawm cov roj thiab cov roj av, muaj ntau thiab ntau cov txheej txheem cov qhov dej, xws li cov qhov dej loj loj, luv luv. lub vojvoog qhov dej, thiab cov qhov dej qub nrog qhib qhov rais sidetrack drilling kab rov tav qhov dej. Pa laum yeeb nkab tau ntsib qee qhov teeb meem nyuaj thaum siv rau hauv cov txheej txheem qhov dej no. Piv txwv li, nyob rau hauv ultra-luv vojvoog kab rov tav qhov dej, lub borehole curvature yog heev me me (<18m), which makes the conventional drill pipe generate large alternating stress. The fatigue fracture of drill pipe caused by alternating stress occurs from time to time, which brings significant losses to the oilfield. In order to solve these problems, foreign countries began to start from new materials, the development of titanium alloy drill pipe, aluminum alloy drill pipe, composite drill pipe and so on instead of conventional drill pipe.

Laboratory paub tseeb tias thaum lub cyclic kev nyuaj siab nyob rau ntawm 30, 000psi-40, 000psi, lub neej qaug zog ntawm titanium yog 10 npaug ntawm cov hlau zoo tib yam, thiab cov coefficient ntawm elasticity ntawm titanium. alloy tubing yog hais txog 16.5msi, uas yog ntau elastic dua steel laum yeeb nkab, thiab yog haum rau high-curvature zoo seem. Tam sim no, peb twb tau tsim titanium alloy laum yeeb nkab nrog kev lag luam zoo, cov khoom siv yog Ti-6Al-4V yeeb nkab lub cev tom qab kev ntxhov siab ntawm ob qho kawg thiab pob tw-welding cuab yeej pob qij txha ntawm ob qho kawg, qhov loj ntawm titanium yeeb nkab lub cev ua tau raws li API tus qauv, thiab qhov ntev yog 2 lossis 3 nyob rau hauv qhov ntau ntawm API tus qauv. Txhawm rau txo cov nqi tsim khoom, cov cuab yeej pob qij txha yog ua los ntawm cov hlau, thiab cov pob qij txha xov yog hauv av los ntawm cov khoom siv sab saud, thiab cov pob qij txha OD yog welded nrog cov kab xev hnav-tiv taus. Titanium alloy laum yeeb nkab kuj tseem siv rau hauv cov qhov dej tob tob thiab cov qhov dej loj loj. Vim qhov tsawg ntom ntom ntawm titanium alloy, nws tuaj yeem txo qhov kev sib tw loj los ntawm 30%, txo lub zog los ntawm 30-40%, txhim kho qhov tensile margin thiab kev nyab xeeb ntawm cov cuab yeej drilling, thiab txhim kho kev muaj peev xwm. nrog rau qhov nyuaj ntawm kev sib tsoo.
Nyob rau hauv ib puag ncig txhua hnub, kev pab cuam lub neej ntawm titanium alloy laum yeeb nkab yog 10 npaug ntawm cov pa steel laum yeeb nkab ntawm tib qhov tshwj xeeb; nyob rau hauv ib puag ncig corrosive, nws yog 100 npaug ntawm cov pa laum yeeb nkab.
Ntxiv nrog rau cov kav dej tho, cov kav dej tawm sab nrauv, cov khoom siv hluav taws xob, cov twj tso kua mis, cov twj, thiab lwm yam.
Piv txwv li, lub tebchaws United States of America lub North Hiav txwv roj rigs, nrog 100 titanium tshav kub exchangers; Norway's Heidrum project, nrog lub ntiaj teb thawj zaug titanium high-pressure riser raj ncej.
Titanium yog txhim khu kev qha: titanium tiv taus corrosion thiab muaj lub neej ua haujlwm ntev dua.
Offshore roj extraction platforms, lom lom paug tshwm sim los ntawm corrosion ntawm structural Cheebtsam yog heev haib. Feem ntau, cov cuab yeej ua los ntawm cov pa hlau yog sab laug "ib nrab-tuag". ......
Txawm li cas los xij, qhov saum npoo ntawm titanium muaj cov txheej txheem tsim, ntom ntom, tsis muaj zog, xeb-tiv taus, corrosion-resistant oxidized zaj duab xis, tsis tas yuav tsum tau kho ntxiv los tiv thaiv corrosion, tuaj yeem tiv taus corrosion ntawm seawater, sulfuric acid, petrochemicals.
Titanium Cheebtsam, tuaj yeem pab cov roj drilling rau hauv cov dej tob thiab qhov tob tob, nrog rau qhov kub thiab txias ntau dua (piv txwv li, ntau ntsev) ib puag ncig ntau lawm.
Nrog titanium, rigs tsuas yog tshawb nrhiav thiab tsis ntshai dab tsi!
Feem ntau ntawm Tuam Tshoj cov khoom siv roj av yog cov roj av uas muaj leej faj, xws li Tarim hauv Xinjiang thiab Sichuan Basin, ob qho tib si yog cov chaw muaj roj sulfur siab. High-muaj H2S2, C2O2 roj thiab roj teb yeeb nkab corrosion, siab kub thiab siab siab tej yam kev mob rau lub sij hawm ntev kev pab cuam yog ib tug nyuaj teeb meem ntawm cov roj thiab roj kev loj hlob, kev xaiv ntawm high-zoo corrosion-resistant cov ntaub ntawv rau cov yeeb nkab tau los ua tus qhov tseem ceeb. Titanium alloy nrog nws zoo heev tsis kam mus rau pitting corrosion, yog siv rau high sulfur ib puag ncig, tshwj xeeb tshaj yog hnyav tej yam kev mob, Cl thiab H2S cov ntsiab lus yog siab heev, dav stainless hlau, thiab txawm nickel-based alloys yog corrosion tshwm sim.
Titanium yog txhim khu kev qha: titanium yog sib dua thiab hloov tau yooj yim hauv kev ua haujlwm.
Txawm li cas los xij, titanium pas nrig muaj zog dua li cov pas nrig hlau
Txawm li cas los xij, titanium rods kuj sib dua, hnyav yuav luag ib nrab ntau npaum li cov hlau hauv tib lub ntim.
Vim hais tias titanium rods yog sib zog, lub torque ntawm drilling yog txo los ntawm ze li ntawm 50%, lub load ntawm sab saum toj tsav rau hauv av yog correspondingly me me (PS: me zog quab yuam, ntxaum thiab ruaj khov drilling), thiab cov cuab yeej tsis yooj yim rau tawg. .
Yog li, titanium rods muaj zog thiab sib zog, lawv tuaj yeem txuag tau ntau lub zog, roj thiab khoom siv.
Titanium alloy no pas nrig, siv nws, nws yog ib phau ntawv, tua ob tug kwv tij ntawm hlau!
Tshuaj titanium, titanium txhim khu kev qha!
