Titanium Gr 5 Gr 7 Gr 9 Ncaj Yeeb Nkab kom zoo dua
(1). Raws li tus neeg siv khoom daim ntawv thov teb, cov qauv sib txawv tuaj yeem ua rau hauv cov duab disc, puag ncig, raj, coil lossis profile.
(2). Tag nrho cov titanium raj yog ua tiav, uas txo cov kev sib txuas ncaj qha ntawm lub raj thiab ruaj khov dua.
(3). Raws li ib puag ncig siv, siv cov kav dej sib txawv thiab cov tuab kom tau raws li cov neeg siv khoom xav tau rau qhov loj tshaj plaws.
(4). Muaj zog corrosion kuj.

Yog, nrog rau kev xaiv hlau muab tub lim tsim nyog:
Gr5 rau Gr5: ERTi-5 muab tub lim
Gr5 rau Gr7: ERTi-5 lossis ERTi-7 (sib tham daim ntawv thov)
Gr5 rau Gr9: ERTi-9 feem ntau haum
Q2: Dab tsi yog qhov siab tshaj plaws ntsuas rau titanium kav?
Kev ntsuas siab nyob ntawm qib, qhov loj, phab ntsa thickness, thiab kub. Nrog ASME B31.3 rau cov txheej txheem piping lossis cov lej tsim tshwj xeeb. Raws li cov lus qhia, Teem caij 10S Qib 5 yeeb nkab tuaj yeem ua haujlwm 2000-4000 psi nyob ntawm txoj kab uas hla.

Feem ntau yog, tab sis nrog kev txwv:
Qib 5: Kev txwv tsis pub dhau, yuav xav tau kev txiav txim siab tshwj xeeb
Qib 7: Kev tiv thaiv zoo heev rau sulfide kev ntxhov siab tawg
Qib 9: Kev ua haujlwm zoo, feem ntau teev rau kev pabcuam qaub
Q4: Dab tsi nto tiav muaj rau siab -purity daim ntaub ntawv?
Rau kev siv tshuaj, semiconductor, thiab zoo sib xws:
Electropolished sab hauv (Ra tsawg dua lossis sib npaug rau 0.4μm)
Ntxuav thiab passivated
Muab ob npaug rau -bagged nyob rau hauv lub cleanroom tej yam kev mob
