Qib 9 Ti-3Al-2.5V Titanium Tubing rau Tsheb kauj vab ncej, Seamless
Oct 20, 2025
Vim li cas Qib 9 Titanium raug xaiv rau lub tsheb kauj vab Tubing
Qib 9 titanium (Ti-3Al-2.5V, UNS R56320) yog cov khoom siv rau siab-kawg hlau tsheb kauj vab thav duab rau ntau xyoo lawm. Yog vim li cas yog qhov sib npaug uas tsis muaj lwm yam yooj yim welded hlau xa tuaj ntawm tib qhov hnyav: qhov ntom ntawm li 4.48 g / cm3, chav tsev kub tensile lub zog ntawm 620 MPa yam tsawg kawg nkaus, kev qaug zog txwv uas yog siab txheeb ze rau nws qhov hnyav, thiab txaus txias formability yuav tsum tau kos rau hauv nyias, butted hlab. Cov hlau yog ib qho ze-alpha titanium qib uas ua rau kev tiv thaiv corrosion ntawm titanium unalloyed, yog li tus ncej liab qab yuav tsum tsis muaj xim kom ciaj sia txoj kev ntsev thiab hws.
Ncej tsim siv cov khoom siv ntau dua li sib ntaus sib tua. Vim tias titanium muaj kwv yees li ib nrab ntawm cov hlau tsis zoo ntawm cov phab ntsa zoo sib xws, cov neeg tsim qauv siv cov kab loj sab nraud thiab cov phab ntsa nyias kom rov qab khoov thiab torsional nruj thaum ua kom lub teeb pom kev zoo. Qib 9 zam qhov nyias nyias - phab ntsa geometry zoo dua li siab dua - qib titanium zog vim nws tuaj yeem ua kom txias thiab zoo li tsis tawg.

Tube yog muab los ntawm cov raj ncaj seamless los yog raws li welded-thiab-raws raj, nyob rau hauv round, oval, aero ({2}}zoo li tus lossis pob zeb diamond profiles. Round tube tseem yog tus qauv ntsuas rau lub zog ib gram, thaum zoo li tus profiles yog siv nyob rau hauv qhov chaw uas tus tsim xav kom tune lateral stiffness los yog txhim kho tuav hauv ib lub raj sib koom.
Butted thiab Tapered Phab Ntsa Design
Ib qho ncaj ncaj-gauge raj yog cov khoom siv yooj yim tshaj plaws, tab sis feem ntau cov kev ua haujlwm thav duab siv lub taub hau uas cov phab ntsa yog thicker ntawm ob qho tag nrho thiab thinner nyob rau hauv nruab nrab. Cov tuab tuab nqa cov vuam cua sov- thaj tsam cuam tshuam thiab lub sijhawm khoov ntawm qhov sib koom ua ke, thaum lub chaw nyias nyias txo cov huab hwm coj qhov kev ntxhov siab qis tshaj. Ib qho piv txwv ob -butted geometry rau lub raj sab saum toj yog 0.9 hli ntawm txhua qhov kawg thiab 0.7 hli nyob rau hauv nruab nrab, nrog rau sab nraud - txoj kab uas hla. Triple-butted tube ntxiv cov kauj ruam thib ob kom qhov kev hloov pauv maj mam thiab qhov kev ntxhov siab nyob ntawm phab ntsa hloov pauv. Cov neeg yuav khoom yuav tsum hais kom meej qhov kawg thickness, nruab nrab thickness thiab hloov ntev sib cais, vim hais tias peb tus lej txhais ob qho tib si qhov hnyav thiab lub neej qaug zog ntawm tus ncej.
Vuam thiab ncej-Vuam tu rau cov ncej Builders
Qib 9 cov raj tau koom nrog cov roj tungsten arc vuam, feem ntau tsis muaj cov khoom ntim rau ntawm nyias- cov phab ntsa mitred pob qij txha, lossis nrog ERTi-9 muab tub lim qhov sib txawv me me yuav tsum tau ntim. Titanium tsis tuaj yeem welded nyob rau hauv huab cua: lub pas dej molten thiab cov hlau kub tom qab nws nqus oxygen, nitrogen thiab hydrogen, thiab qhov sib koom ua ke poob ductility. Cov cai siv tau yog:
Tshem tawm sab hauv ntawm lub raj thiab tiv thaiv sab nraud nrog siab -purity argon; tsis txhob welding kom txog thaum lub purge tau tsav cov pa oxygen.
Khaws cov cua sov kom tsawg, siv lub lens roj, thiab cia txhua qhov vuam txias ua ntej tom ntej kom lub thav duab tsis tsim kom sov.
Npaj rau lub ci nyiaj hlaws. Kub lossis straw xim yog siv tau hauv qee lub khw, tab sis xiav lossis grey qhia tias muaj kab mob thiab yuav tsum tau txiav tawm thiab rov ua dua -welded.
Tshem tawm cov cua sov tint tshuaj los yog mechanically tom qab vuam, vim cov tinted txheej yog nkig thiab yog ib qho kev qaug zog tawg pib qhov chaw.
Yog tias qhov sib koom ua ke yuav tsum tau txo qis kev ntxhov siab rau daim ntawv thov, siv lub tshuab nqus tsev tswj lossis inert- atmosphere furnace ntawm qhov kub nruab nrab es tsis yog lub teeb.
Fatigue, Caij Zoo thiab Durability
Ncej tsis ua hauj lwm, thaum lawv tshwm sim, yuav luag ib txwm qaug zog tsis ua hauj lwm ntawm welds, tsis overload tsis ua hauj lwm nyob rau hauv lub raj lub cev. Titanium lub zog qaug zog yog qhov zoo, tab sis cov cua sov- cuam tshuam cheeb tsam thiab cov ntiv taw vuam yog cov ntsiab lus tsis muaj zog, yog li vuam zoo, raj- kawg haum- nce thiab xa tawm -weld huv si dominate kev pab cuam lub neej. Hauv cov ntsiab lus caij tsheb, qhov qis qis ntawm titanium muab cov thav duab uas cuam tshuam txoj kev vibration pom zoo piv nrog cov hlau los yog txhuas, thiab kev tiv thaiv corrosion txhais tau hais tias lub thav duab tsis degrade los ntawm sab hauv raws li cov xim hlau thav duab. Kos nyob twj ywm kom zoo nkauj vim tias cov yeeb yaj kiab oxide passive hloov kho tam sim ntawd ntawm qhov chaw raug.
Kev Ntseeg Tsis Zoo
Qib 9 tsis yog cov khoom siv titanium uas muaj zog tshaj plaws. Qib 5 (Ti-6Al-4V) muaj zog dua tab sis deb dua kom txias txias rau hauv nyias lub taub hau thiab vuam hauv lub khw me.
Anodizing thiab xim tiav yog cov tshuaj pleev ib ce; lawv tsis txhim kho lub neej qaug zog ntawm tus ncej.
Thinner tsis tau zoo dua. Hauv qab li 0.5 hli phab ntsa nyob rau hauv nruab nrab seem, dent resistance thiab buckling kuj poob sai.
Qib 9 tubing tsis hloov pauv nrog cov khoom lag luam ntshiab Qib 2 lub raj uas tsim los ntawm kev siv zog ntau dua.
FAQ
Q: Vim li cas Qib 9 siv rau cov raj tsheb kauj vab es tsis yog Qib 5?
Qib 9 sib xyaw ua ke kom muaj zog txaus nrog kev ua kom txias txias thiab weldability, uas tso cai rau nyias, pob tw raj los kos thiab koom nrog kev ntseeg siab.
Q: Ntau npaum li cas lub pob tw tubing txo tus ncej hnyav?
Qhov kev txuag yog nyob ntawm qhov profile, tab sis ob npaug -butted teeb feem ntau tshem tawm 15-25% ntawm lub raj loj piv nrog cov raj ncaj ncaj ntawm tib qhov kawg tuab.
Q: Qeb 9 puas tuaj yeem welded hauv tsev?
Nws tuaj yeem yog TIG welded, tab sis tag nrho argon purging, tsis tshua muaj cua sov input thiab post-weld tint tshem tawm yog qhov tseem ceeb; Yog tsis muaj lawv qhov sib koom ua nkig.
Q: Puas yog titanium thav duab xav tau xim?
Tsis yog. Cov zaj duab xis oxide passive tiv thaiv cov hlau, yog li cov xim pleev xim yog kev xaiv kom zoo nkauj dua li qhov yuav tsum tau muaj corrosion.
Q: Dab tsi ntawm phab ntsa thickness yog raug rau lub tsheb kauj vab sab saum toj raj?
Muab ob npaug rau- taub qab cov raj sab saum toj feem ntau khiav 0.9 hli ntawm qhov kawg thiab 0.7 hli hauv nruab nrab, nrog rau qhov profile tiag tiag los ntawm tus tsim qauv.
Q: Ntev npaum li cas lub tsheb kauj vab titanium yuav kav ntev?
Lub neej qaug zog yog tswj hwm los ntawm kev sib txuas zoo thiab haum- tsis yog los ntawm lub raj nws tus kheej; lub qhov dej - ua thav duab uas tsis txhob muaj kab mob thaum lub sij hawm vuam muaj lub neej ua haujlwm ntev heev.
