Qhov zoo ntawm lub raj tooj liab

1. Muaj kev nyab xeeb thiab txhim khu kev qha:cev toojintegrates qhov zoo ntawm cov yeeb nkab hlau thiab cov yeeb nkab tsis yog hlau.Nws yog ib qho nyuaj tshaj li cov yeeb nkab yas, nrog lub zog siab ntawm cov hlau dav hlau (txias kos tooj liab yeeb nkab lub zog thiab tib phab ntsa tuab ntawm cov yeeb nkab steel);Nws yog hloov tau ntau dua li cov hlau zoo tib yam, zoo toughness thiab siab ductility, nrog zoo heev kev co kuj, cuam tshuam kuj thiab te heave kuj.

2. Durable: tshuaj lom neeg kev ua tau zoo ntawm tooj liab tooj liab yog ruaj khov, txias tsis kam, kub tsis kam, siab tsis kam, corrosion kuj thiab hluav taws kub tsis kam thiab lwm yam ntxwv nyob rau hauv ib tug, yuav siv tau nyob rau hauv txawv ib puag ncig ntev.

3. Kev noj qab haus huv: txhua yam kev hloov pauv, tshuaj ntxiv, tshuaj ntxiv thiab lwm yam tshuaj muaj pes tsawg leeg ntawm cov yeeb nkab yas hauv cov raj tooj liab.

4. Muaj zog tooj liab tube kev sib txuas: tooj liab yeeb nkab thiab tooj liab fittings kev twb kev txuas, muaj zog firmness.

5. Tus nqi ntawm cov raj tooj liab yog kev lag luam, nyob rau hauv cov txheej txheem ntawm kev txhim kho cov yeeb nkab tooj liab yuav nco ntsoov txuag tau ntau cov ntaub ntawv, cov yeeb nkab tooj liab yog qhov yooj yim heev rau txheej txheem.Qhov zoo yog lub teeb, piv nrog lwm cov hlau dub threaded yeeb nkab ntawm tib lub puab kab uas hla, cov yeeb nkab tooj liab tsis tas yuav tsum yog tuab li cov hlau dub tuab, cov nqi tsheb thauj mus los ntawm cov yeeb nkab tooj liab installation yog qis dua, thiab nws yooj yim heev los tswj.Copper kuj muaj peev xwm hloov cov duab ntawm lub siab nyiam, yog li cov raj tooj liab tuaj yeem khoov lossis deformed thiab txuas tau yooj yim.Vim yog cov yam ntxwv uas liab tooj liab tuaj yeem deformed ntawm lub siab, liab tooj liab yeeb nkab kuj tau ua rau liab tooj liab raj fittings.Liab tooj liab kuj muaj cov yam ntxwv ntawm corrosion kuj thiab kev tiv thaiv ib puag ncig.Nws tau hais tias archaeologists tau pom ntau txhiab xyoo cov kav dej liab liab nyob rau hauv cov pyramids ntawm Egypt, thiab cov dej ntws tawm ntawm cov tooj liab tseem tuaj yeem siv tau.Yog li ntawd, qhov zoo ntawm cov yeeb nkab liab tooj liab tuaj yeem ua tiav raws li kev lag luam kev lag luam, kev sib txuas yooj yim, kev nyab xeeb, kev tiv thaiv corrosion.
