Titanium Tubing Rau Lub Tshuab Nqus Tsev

 

Titanium tubing rau lub tshuab nqus tsev yog qhov siab - cov khoom siv kawg siv hauv lub tshuab nqus tsev nqus tsev vacuum, muaj ntau yam khoom zoo heev uas txhim kho kev ua tau zoo thiab cov neeg siv kev paub ntawm lub tshuab nqus tsev.

Titanium tubing feem ntau yog siv nyob rau hauv siab - kawg lub tshuab nqus tsev vacuum, tshwj xeeb tshaj yog cov tsim los siv nyob rau hauv tshwj xeeb ib puag ncig, xws li industrial nqus tsev vacuum los yog cov tsim los ntxuav cov av noo los yog corrosive ib puag ncig. Tsis tas li ntawd, qee qhov siab -zoo, ntev- lub neej hauv tsev lub tshuab nqus tsev kuj tseem siv tau titanium tubing.

 

 

1) Lub teeb yuag thiab siab - lub zog:

Titanium alloy muaj qhov ceev ntawm kwv yees li 4.5 g / cm³, tsuas yog 60% ntawm cov hlau, tab sis nws lub zog yog piv rau siab - steel zoo, ua kom pom qhov zoo ntawm chav tsev. Qhov no ua rau lub titanium hose ntawm lub tshuab nqus tsev vacuum ob lub teeb yuag thiab ruaj khov, yooj yim rau cov neeg siv khiav lag luam thiab nqa, thaum tseem tiv taus lub zog ntawm lub tshuab nqus tsev thaum ua haujlwm.

2) High corrosion kuj:

A dense oxide film forms on the surface of the titanium tube, which can resist corrosion from seawater, strong acids, chloride ions, etc., and its lifespan can be more than 5 times that of carbon steel. Yog li ntawd, txawm nyob rau hauv ib puag ncig tu hnyav, titanium raj tsis yooj yim corroded, kom ntseeg tau lub neej kev pab cuam ntawm lub tshuab nqus tsev vacuum.

3) Zoo thermal stability:

Txawm nyob rau ntawm qhov kub ntawm 450-500 degree, titanium tubing tuav lub zog tshwj xeeb, deb tshaj li ntawm aluminium alloys. Txawm hais tias qhov kub thiab txias ntawm lub tshuab nqus tsev feem ntau tsis ncav cuag cov qib siab thaum lub sijhawm ua haujlwm ib txwm muaj, tshwj xeeb, xws li kev siv txuas ntxiv mus ntev lossis lub cev muaj zog ua haujlwm tsis zoo ua rau qhov kub thiab txias, qhov thermal stability ntawm titanium tubing xyuas kom meej tias nws cov kev ua haujlwm tseem tsis cuam tshuam.

4) Muaj zog tiv thaiv kev ntxhov siab corrosion:

Hauv cov tshuaj chloride- muaj ib puag ncig, titanium tubing nthuav tawm qhov ua tau zoo dua rau pitting thiab kev ntxhov siab corrosion tawg dua li cov hlau tsis muaj steel. Qhov no ua rau titanium tubing ntau txhim khu kev qha rau cov tshuab nqus tsev vacuum siv nyob rau hauv qhov chaw ntub dej lossis thaum ntxuav cov stains uas muaj ntsev.

5) Tsawg coefficient ntawm linear expansion:

Titanium tubing tsuas muaj 50% ntawm cov coefficient ntawm linear expansion ntawm steel, uas ua rau tsawg deformation thaum lub sij hawm kub hloov. Cov yam ntxwv no txo ​​qhov kev pheej hmoo ntawm kev xau ntawm cov yeeb nkab sib txuas, ua kom lub tshuab nqus tsev nqus cov foob sab hauv thiab yog li txhim kho kev nqus dej.

 

 

Ti Ntau dua lossis sib npaug li 99.5% (matrix element, balance)

Fe Tsawg dua lossis sib npaug rau 0.30 yog qhov tsis huv loj uas cuam tshuam rau plasticity.

O Tsawg dua los yog sib npaug rau 0.25 interstitial ntsiab txhim kho lub zog thiab txo cov yas.

N Tsawg dua los yog sib npaug rau 0.03 interstitial cov ntsiab lus, nrog cov ntsiab lus nruj tswj xyuas kom muaj zog.

C Tsawg dua los yog sib npaug rau 0.10 interstitial caij, kom tsis txhob tsim cov carbides nyuaj.

H Tsawg dua lossis sib npaug ntawm 0.015 nruj me ntsis tswj cov ntsiab lus hydrogen kom tiv thaiv hydrogen embrittlement.

 

 

Cov cuab yeej siv tshuab tau muab faib ua lub xeev annealed (xeem lub xeev, code M) thiab txias -lub xeev ua haujlwm. Annealed xeev yog lub xeev tseem ceeb rau kev siv cov raj xa dej, nrog kev ua haujlwm ruaj khov thiab ua haujlwm yooj yim.

Tensile zog (Rm): 400 ~ 480 MPa

Yield zog (Rp0.2): 300 ~ 350 MPa

Elongation: 25% ~ 35%

Txo thaj tsam (Z): 50% ~ 60%

Elastic modulus (E): 110 GPa

Hardness (HB): 110 ~ 150

 

 

A. Impurities thiab lawv qhov cuam tshuam:

Cov pa oxygen thiab cov ntsiab lus hlau yog cov ntsiab lus tseem ceeb uas txiav txim siab lub zog ntawm GR2. Cov ntsiab lus siab dua nce lub zog tab sis txo cov plasticity; yog li ntawd, cov ntsiab lus impurity ntau yuav tsum tau sib phim raws li daim ntawv thov scenario.

B. Kev ua tau zoo:

Annealed GR2 nthuav tawm cov yas zoo heev thiab tuaj yeem txias - khoov, stamped, thiab welded. Lub zog ntawm welded pob qij txha tuaj yeem ncav cuag ntau dua 90% ntawm cov khoom siv hauv paus, ua tau raws li cov kev xav tau ntawm cov kav dej txuas.

C. Corrosion kuj:

GR2's corrosion kuj stems los ntawm nws ntom ntom TiO₂ oxide zaj duab xis. Lub purity ntawm zaj duab xis no ncaj qha cuam tshuam nws txoj kev ncaj ncees; ntau impurities yuav txo tau localized corrosion kuj.
