Lub luj tshib 90℃uas tsis phim cov yeeb nkab ntawm qhov chaw txhais tau hais tias rov ua haujlwm, ncua sij hawm, thiab tsis nco qab qhov tseem ceeb - thiab nws feem ntau pom tsuas yog tom qab lub thawv twb tau muab tshem tawm lawm. GNEE yog lub chaw tsim khoom txhuas nrog 18 xyoo ntawm kev xa tawm, muab ASTM B361 / ASME B16.9 aluminium taub qab-weld fittings nyob rau hauv ntau yam ntawm cov alloys rau distributors, fabricators, thiab engineering cog lus nyob rau hauv ntau tshaj 100 lub teb chaws.
Ua ntej ntim peb rov- xyuas qhov tseem ceeb haum qhov ntev - sab nraud txoj kab uas hla, phab ntsa, thiab bevel - tawm tsam daim duab pom zoo, yog li qhov tsis sib xws raug ntes hauv peb lub rooj cob qhia, tsis yog ntawm koj qhov chaw nres nkoj txais. Peb aluminium 90℃ntev vojvoog luj tshib muab rau koj lub teeb yuag, corrosion-resistant, weldable hloov ntawm kev taw qhia rau cov kav dej, muaj nyob rau hauv 6061, 6063, 6082, 5083, 5052, 3003, thiab 1050/1060, yog li koj tuaj yeem phim cov kev pabcuam.
Dab tsi yogAluminium 90℃Ntev Radius Luj Tshib?
Aluminium 90℃ntev vojvoog lub luj tshib yog lub pob tw -weld yeeb nkab haum uas tig lub raj xa dej los ntawm 90 degrees siv lub voj voog nruab nrab ntawm 1.5 × lub nominal yeeb nkab txoj kab uas hla (1.5D). Lub vojvoog ntev (LR) profile ua rau lub ntsej muag maj mam dhau lub vojvoog luv luv (1D) lub luj tshib, uas ua rau qis qis, txo qhov poob siab, thiab txwv tsis pub khiav tawm -vim kev co. Rau feem ntau cov txheej txheem thiab cov kav dej siv hluav taws xob, LR lub luj tshib yog lub neej ntawd tshwj tsis yog qhov chaw teeb tsa raug txwv.
Aluminium yog xaiv los ntawm cov pa roj carbon steel thaum hnyav, corrosion, lossis tsis yog - tus cwj pwm tsis zoo ua rau tus qauv tsim. Ntawm ib ncig ntawm ib qho -peb qhov ntom ntawm cov hlau, aluminium luj tshib txiav tuav thiab txhawb nqa thiab tiv thaiv atmospheric corrosion tsis muaj txheej. Txoj cai alloy nyob ntawm qhov kev pab cuam: 6xxx qib rau lub zog thiab weldability, 5xxx rau marine lub luag hauj lwm, thiab 3xxx thiab 1xxx rau formability thiab purity.

Corrosion Resistance
Aluminium ua tus kheej -kho oxide txheej uas tiv thaiv cov huab cua feem ntau. Kev ua tau zoo los ntawm ib puag ncig:
Atmospheric:Zoo nyob rau hauv kev nyob deb nroog, nroog, thiab muaj huab cua; kev pabcuam sab nraum zoov yog niaj hnub nrog lossis tsis muaj txheej.
Tubrog nkoj:5xxx qib (5083/5052) tiv taus dej hiav txwv immersion zoo tshaj; 6xxx suits atmospheric marine thiab topside lub luag hauj lwm. Cais tawm ntawm cov hlau / tooj liab hauv kev pabcuam ntub dej.
Galvanic:Aluminium yog anodic rau hlau thiab tooj liab alloys. Siv cov dielectric cais los yog txheej txheej uas cov hlau sib txawv sib ntsib hauv cov dej noo.
Kev ntxhov siab corrosion cracking (SCC):Tsawg susceptibility nyob rau hauv 6xxx thiab 5xxx piv rau 7xxx; zam kom tsis txhob muaj zog tensile ntxiv nrog rau ib puag ncig nruj.
Nrog tiav:Anodizing lossis hmoov txheej txuas ntxiv lub neej thiab txhim kho cov tsos ntawm kev txhoj puab heev lossis tu cev.
Fabrication
Vuam:Join with GTAW (TIG) or GMAW (MIG). Pom zoo fillers yogTIAB SA 4043kom zoo txaus thiab ze dua ncej-anodize xim match, los yogTIAB SA 5356qhov twg siab dua ncej-weld zog yuav tsum tau. Tsim nyog tus txheej txheem; cia siab tias HAZ lub zog poob hauv 6xxx.
Machining:Aluminium lub luj tshib tshuab huv si nrog tus qauv carbide cuab yeej rau qhov kawg tig ntsej muag, drilling, thiab flange nta.
Formability:6xxx hauv O/T4 thiab 3xxx/1xxx/5xxx nyob rau hauv mos tempers daim ntawv yooj yim; Lub luj tshib feem ntau yog tsim los ntawm cov raj tom qab hnub nyoog (6xxx) lossis nkag rau hauv qhov xav tau.
Kev soj ntsuam zoo
Thaum lub luj tshib tuaj txog tsis sib haum lossis nrog qhov tsis zoo ntawm qhov sib tsoo, tus nqi tiag tiag tsis yog qhov - nws yog lub sijhawm poob, cov neeg ua haujlwm rov ua haujlwm, thiab qhov tseem ceeb uas koj nco ntawm qhov chaw. Peb kho qhov kev kuaj ua ntej - zaub mov xa tuaj raws li cov kauj ruam uas tiv thaiv koj, tsis yog kev cai.
Ua ntej ntim, txhua lub luj tshib raug kuaj xyuas cov duab pom zoo thiab koj cov kev xav tau. Rau kev tsim cov welded peb txheeb xyuas qhov vuam profile thiab khiav qhov kev ntsuam xyuas pom raws li cov txheej txheem pom zoo, thiab siv zas xim -penetrant (PT) lossis ultrasonic (UT) kuaj qhov project qhia nws. Qhov tseem ceeb haum qhov ntev - sab nraud txoj kab uas hla, phab ntsa thickness, bevel kaum sab xis, thiab nruab nrab -rau-kawg (A) - yog ntsuas kom lub luj tshib zaum ntawm koj cov yeeb nkab thawj zaug.
Kev lees txais raug txiav txim tawm tsam daim duab kos, qauv, lossis koj qhov kev xav tau, tsis yog qhov "pass." Yog tias qhov loj me lossis qhov tshwm sim weld ntog sab nraum qhov txwv, peb cais cov khoom ntawd los ntawm cov khoom siv, rov- xyuas nws nrog ob txoj hauv kev, thiab txiav txim siab rov ua dua lossis hloov ua ntej nws tuaj yeem txav mus rau txheej txheem tom ntej. Cov teeb meem nyob hauv peb lub rooj cob qhia; lawv tsis ntws mus rau koj qhov chaw nres nkoj txais.
Rau aluminium yeeb nkab fittings no ua raws li ASTM B361 thiab ASME B16.9, thiab cov ntaub ntawv pov thawj tau xa nrog EN 10204 3.1 daim ntawv pov thawj zeb xeem.
