ASTM B337 Titanium Tube
ASTM B337 titanium raj no npog yim qib (gr1, gr2, gr3, gr7, gr9, gr10, gr11 thiab gr12) ntawm seamless thiab welded titanium raj npaj rau kev corrosion-tiv taus thiab siab-kub kev pab cuam.
Khoom Taw qhia
1.1 ASTM B337 titanium raj yuav ua tau los ntawm txhua txoj kev seamless (txias dov) uas yuav ua rau cov khoom ua tau raws li qhov yuav tsum tau ua ntawm cov lus qhia no.
1.2 Titanium raj yuav tsum tau ua los ntawm cov khoom siv tiaj tus dov los ntawm cov txheej txheem arc-welding uas yuav ua rau cov khoom ua tau raws li qhov yuav tsum tau ua ntawm qhov kev qhia tshwj xeeb no, Filler hlau, yog siv, yuav tsum yog qib tib yam li lub hauv paus hlau, lossis lub zog qis dua tom ntej. Qib rau vuam Qib 2 thiab 3. Rau vuam Qib 7, 9, 10, 11, thiab 12, cov hlau muab tub lim, yog siv, yuav tsum zoo ib yam li qib tau teev tseg. Welded yeeb nkab tej zaum yuav raug txo ntxiv.
1.3 Nws yuav tsum tau muab tso rau hauv annealed, tshwj tsis yog rau Qib 9, uas tej zaum yuav muaj nyob rau hauv lub annealed los yog stress-relief annealed mob, thiab Qib 10, uas yuav tsum tau kho.

ASTM B337 titanium raj tiav yuav tsum ncaj ncaj, yuav tsum muaj qhov kawg, tsis muaj burrs, thiab yuav tsum tsis txhob raug mob sab nraud thiab sab hauv tsis zoo ntawm qhov xwm txheej uas yuav cuam tshuam rau lub hom phiaj uas nws tau npaj. Cov teeb meem me me tuaj yeem raug tshem tawm muab qhov ntsuas qhov ntev ntawm cov lus hauv qab no tsis tshaj. Tshwj tsis yog tias tau teev tseg, cov yeeb nkab yuav tsum tau muab cov khoom tsis muaj qhov ntsuas.
Nws muaj lub zog thermal siab. Kev khiav hauj lwm ib puag ncig kub yog ob peb puas degrees siab dua li ntawm aluminium alloy, thiab nws tseem tuaj yeem tuav lub zog xav tau ntawm qhov nruab nrab thiab qhov sib txawv. Nws tuaj yeem txhim kho thiab ua haujlwm ntev ntawm qhov kub ntawm 450-500 degree . Kev tshawb fawb tseem muaj lub zog tshwj xeeb heev, thaum lub zog tshwj xeeb ntawm aluminium alloy tuaj yeem txo qhov pom tseeb ntawm 150 degree. Kev ua haujlwm kub ntawm alloy titanium raj tuaj yeem ncav cuag 500 degree, thaum cov khoom siv aluminium alloy qis dua 200 degree.
