Vim li cas titanium alloys dhau los ua cov ntaub ntawv tseem ceeb rau cov xwm txheej hnyav hauv roj thiab roj rho tawm?

Roj thiab roj rho tawm tau txav mus rau hauv qhov chaw huab cua xws li dej hiav txwv sib sib zog nqus thiab qhov dej tob los ntawm kev xav tau lub zog thoob ntiaj teb. Corrosive media, kub siab, siab siab, thiab complex stresses impose stringent yuav tsum tau rau kev ua tau zoo ntawm cov khoom siv.Titanium alloys,nrog rau lawv cov khoom zoo heev, tau tshwm sim los ua cov kev daws teeb meem tseem ceeb, ua kom muaj kev nyab xeeb, muaj txiaj ntsig zoo, thiab ntsuab kev loj hlob ntawm cov roj thiab roj extraction.

 

 

Titanium alloysmuaj kev tiv thaiv corrosion los ntawm qhov ntom ntom, ruaj khov, thiab tus kheej - kho oxide zaj duab xis ntawm lawv qhov chaw.

Kev tiv thaiv corrosion heev: haum rau ib puag ncig nrog siab Cl⁻, H₂S, CO₂, thiab dej hiav txwv.

 

Strong adaptability ntawm txhua yam khoom: High tshwj xeeb lub zog txo qhov hnyav thiab load; low elastic modulus txhim khu kev qaug zog tiv thaiv, yoog rau alternating load tej yam kev mob.

Kev lag luam ntau dua tag nrho- lub neej voj voog: Kev pabcuam lub neej txuas ntxiv mus rau ntau dua 15 xyoo, txo cov nqi los ntawm 30%-40%.

 

 

1. Sib sib zog nqus / Ultra- Qhov tob tob thiab siab -Acid Gas Well Extraction

Sib sib zog nqus/ultra- qhov tob tob thiab siab - cov dej kua qaub yog qhov tseem ceeb ntawm kev tshem tawm roj thiab roj.

 

Cov kev ua haujlwm muaj xws li kub thiab siab, nrog rau kev sib xyaw ua ke los ntawm H₂S, CO₂, thiab Cl⁻, ua rau hydrogen embrittlement thiab kev ntxhov siab tawg hauv cov ntaub ntawv ib txwm muaj.

 

Titanium alloys (feem ntau Gr5 / Gr7 / Gr12) yog tsim rau cov roj casings, tubing, laum kav, thiab cov cuab yeej downhole. Nrog muaj zog corrosion kuj, muaj zog tshwj xeeb, thiab qaug zog tsis kam, lawv tuaj yeem tiv taus cov khoom hnyav thiab txo cov kev pheej hmoo ntawm cov yeeb nkab hlua tawg thiab ua kom zoo.

Cov khoom siv tsis pom kev xeb lossis xau rau 5 xyoos tom qab thov hauv qhov chaw siab -acid gas field, txo kev txij nkawm thiab xa cov txiaj ntsig zoo heev.

 

2. Sib sib zog nqus-Hiav txwv roj thiab roj kev txhim kho

Cov ntsiab lus mob ntawm ntug dej hiav txwv roj thiab roj platforms: Ntau yam kev hem thawj corrosion, xav tau cov qauv kom muaj zog thiab lub teeb yuag.

Ob daim ntawv thov loj ntawm titanium corrosion-resistant alloys:

 

Core platform qauv: Txo qhov hnyav thiab tiv taus cua thiab nthwv dej.

Cov cuab yeej tseem ceeb, Qib Gr2 / Gr7 / Gr5.

Qhov zoo: Lub neej kev pabcuam ntawm titanium alloy seawater heat exchangers yog 8-10 xyoo, nrog kev ruaj khov thiab kev saib xyuas tsawg.

Adaptability rau subsea pipelines: Tiv thaiv seawater corrosion thiab stress corrosion cracking (SCC). Nws tuaj yeem tiv thaiv kev xau thiab txo cov pa phem hauv hiav txwv.

 

3. Short-Radius Kab rov tav Wells thiab Coiled Tubing Operations

Short/ultra- luv luv vojvoog kab rov tav qhov dej: Mainstream rau nruj / shale gas txoj kev loj hlob, nce kev sib cuag cheeb tsam thiab tus nqi rov qab.

 

Qhov yuav tsum tau muaj: Cov qhov dej loj loj curvature, yuav tsum tau laum cov kav dej / coiled tubing kom muaj kev yooj yim thiab qaug zog; Kev ua haujlwm xav tau kev tiv thaiv rau cov kua qaub thiab tawg ua kua corrosion.

Haum titanium alloy qib: Gr5, Ti-6Al-4V ELI.

Qhov zoo: Kev ua haujlwm txias txias zoo heev, lub neej qaug zog siab, thiab muaj zog corrosion kuj.

Cov khoom siv: Coiled tubing lub cev, pob qij txha, thiab cov tshuaj txhaj.

Ntxiv kom zoo dua: Lub teeb tsim tsim kom muaj kev sib txhuam thiab ua kom zoo, txhim kho kev ua haujlwm ntawm kev sib sib zog nqus zoo.

 

4. Siab -Npauj Valves thiab Fasteners

Cov ntsiab lus tseem ceeb: Siab - lub siab li qub thiab fasteners hauv cov roj thiab cov tshuab hluav taws xob ncaj qha cuam tshuam rau kev ruaj ntseg sealing.

Titanium alloy: Qib Gr5 / Ti-15Mo / Gr7, haum rau valve bonnets, stems, thiab bolts, featuring tsis kam mus siab siab, corrosion, thiab hydrogen embrittlement, kom ruaj khov sealing.

Cov txiaj ntsig ntawm daim ntawv thov: Tus nqi xau poob thiab nws txo qis txhua xyoo los ntawm 200 tons. Nws tseem tuaj yeem ua tiav ob qho kev txhim kho hauv kev nyab xeeb thiab kev lag luam.

 

 

Kev xaiv kev tshawb fawb ntawm titanium corrosion-cov qib resistant alloy raws li kev ua haujlwm yog qhov tseem ceeb kom ua tiav qhov kev ua tau zoo ntawm kev ua tau zoo thiab tus nqi hauv cov roj thiab roj extraction:

 

Gr2: Tus nqi- ua haujlwm tau zoo nrog kev tiv thaiv kev xeb dav dav, haum rau qis- lub zog xav tau qhov xwm txheej xws li cov chaw pabcuam ntawm ntug dej hiav txwv, thiab cov kav dej / kev txhawb nqa nyob rau hauv ib puag ncig corrosive zoo tib yam.
