2. Yuav ua li cas peb hom tooj liab dej raj?
Tawv-kos tooj liab raj: Annealed (rhuab los txo cov brittleness) thiab tom qab ntawd txias-kos rau txoj kev ncaj, tsis muaj kev haum rau kev sib sau ua ke uas yuav tsum muaj tsawg dua khoov rau ....
Ib nrab-nyuaj tooj liab raj: Moderately yoog raws, tso cai me ntsis khoov thaum lub sij hawm cov cuab yeej tshwj xeeb yog qhov xav tau, xws li cov chaw sib luag me lossis ib puag ncig ntawm cov kav dej tsis muaj cov kav dej {}}
Mos (annealed) tooj liab raj: Kev hloov pauv yooj yim los ntawm tes lossis nrog cov cuab yeej siv cov kab tub yees, lossis cov ntawv xov tooj ntawm cov kab tub yees lossis cov pa tub yees lossis cov pa roj caring.
3. Dab tsi yog qhov muaj zog tshaj plaws ntawm tooj liab yeeb nkab?
Siab dua tsis kam (txog li 1, 000+ psi hauv hom diamet me me) piv rau cov hom l thiab m.
Ntau dua kev ruaj khov tiv thaiv sab nraud, xws li cov rog hauv av hauv av sib sau lossis kev sib txawv hauv kev lag luam {}}
Enhanced corrosion tsis kam, raws li cov tuab tuab nyob hauv kev tsis muaj teeb meem hauv qhov chaw hnyav (e {}}}} {{{2}
Hos lwm cov qib yuav ua rau cov ntawv thov kev ntxhov siab, hom K yog mus rau lub tshuab uas yuav tsum tau muaj zog thiab ntev.
4. Vim li cas tooj liab tubing yog kim?
Cov Khoom Siv Raw Khoom Noj: Tooj liab yog cov khoom siv tsis txuas ntxiv, siv tau thiab ua kom zoo dua qub}}
Raug kev lag luam: Hloov pauv tooj liab mus rau hauv tubing cuam tshuam nrog kev tsis sib haum, kos duab, uas yuav tsum tau siv cov khoom siv tshwj xeeb thiab kev ua haujlwm ua haujlwm .
Qhov Zoo: Tooj liab txoj kev tawm tsam, thermal conductivity, thiab biostatic cov khoom (e} gibable}, nce nws cov nqi kho mob .
Kev Lag Luam Dynamics: Cov nqi hloov pauv nrog cov khw muag khoom thoob ntiaj teb, thiab muab cov khoom sib txuas, kev xa khoom qeeb, xa khoom qeeb) tau cov nqi ncua ib ntus).
5. Yog tooj liab tubing 100% tooj liab?
C10200 (Oxygen-Dawb Tooj Liab): Muaj tsawg dua lossis sib npaug ntawm 0 {{{{}} 003% pa, siv hauv kev siv pa purity xws li kev kho mob lossis hluav taws xob qhov twg oxidation qhov kev txhawj xeeb.
C12200 (Dehoxidized Tooj Liab): Xws li cov tshuaj phosphorus me me kom tshem cov pa thaum tsim tawm, txhim kho ductility thiab weldability thiab hvac .
C11000 (electrolytic tawv tawv tooj liab): Cov qib feem ntau, nrog ~ 99. 9% tooj thiab kab oxygen (0.04-0.06%), haum rau cov kav dej thiab hluav taws xob.
Qhov seem 1-0 {. 1% muaj cov kab ua haujlwm yooj yim (e. .
