Cov raj tooj liab (tseem hu ua cov raj tooj liab liab) feem ntau siv hauv cov kav dej, cua sov thiab cua txias kav hauv ntau qhov chaw. Kev sib xyaw ua ke ntawm qhov zoo ntawm ob qho tib si hlau thiab tsis yog xim hlau tubing, tooj liab tubing yog qhov zoo tshaj plaws kev sib txuas rau cov dej kub thiab txias. Copper tubing yog hluav taws kub thiab kub tiv taus, khaws nws cov duab thiab lub zog ntawm qhov kub thiab txias yam tsis muaj kev laus.
Copper tubing yog ob peb lossis ntau ntau lub sij hawm siab dua li cov yas thiab aluminium-yas tubing, thiab tuaj yeem tiv taus cov dej siab tshaj plaws hauv cov tsev niaj hnub no. Nyob rau hauv ib puag ncig dej kub, nrog rau kev txuas ntxiv ntawm kev pab cuam lub neej, lub siab muaj peev xwm ntawm cov yeeb nkab yas poob qis, thaum cov khoom siv hluav taws xob ntawm cov yeeb nkab tooj liab tseem tsis hloov pauv hauv tag nrho cov thermal kub ntau, yog li nws lub siab tsis kam yuav tsis txo, thiab yuav tsis muaj kev laus tshwm sim.
Lub linear expansion coefficient ntawm tooj liab yeeb nkab yog me me, yog 1/10 ntawm cov yeeb nkab yas, yuav tsis ua rau muaj kev ntxhov siab qaug zog rupture vim ntau thermal expansion thiab contraction.
Cov yeeb nkab tooj liab muaj zog dua, txhawm rau txhawm rau txhawm rau ua kom muaj txiaj ntsig zoo hauv txoj kab uas hla, sab nraud txoj kab uas hla yog me dua, haum rau faus.
Txawm koj xav taucov kav dej tooj liab, tooj liab ,tooj liab daim hlau, peb muaj cov khoom thiab kev txawj ntse kom tau raws li koj xav tau.
