Cov khoom siv feem ntau siv rau cov thawv xa khoom thiab hloov txee:

 Carbon steel phaj (galvanized hlau phaj)
Cov pa roj carbon steel phaj yog ib qho ntawm cov khoom siv ntau tshaj plaws rau lub plhaub ntawm lub thawv xa khoom thiab hloov cov khoom. Nws yog pheej yig, weldable, cuttable, thiab yooj yim rau txheej txheem. Qhov saum npoo muaj qee qhov kev tiv thaiv corrosion tom qab electrostatic txau.
 Stainless hlau phaj
Stainless hlau phaj muaj zoo corrosion kuj thiab zoo nkauj, thiab muaj peev xwm tiv taus kub thiab muaj zog acid thiab alkali ib puag ncig. Stainless hlau phaj yog kim thiab nyuaj rau txheej txheem, yuav tsum tau cov khoom siv thiab kev ua haujlwm.
 Aluminium alloy phaj
Aluminium alloy phaj yog lub teeb hauv qhov hnyav, siab zog, ruaj khov, thiab tuaj yeem tau txais kev tiv thaiv corrosion zoo tom qab kev kho oxidation. Aluminium alloy phaj muaj zoo conductivity thiab kub dissipation kev ua tau zoo, thiab yog haum rau high-power hloov txee. Txawm li cas los xij, tus nqi ntawm aluminium alloy phaj yog tus nqi siab.
 Yas phaj
Yas phaj yog lub teeb yuag, insulating plhaub cov khoom uas yooj yim rau txheej txheem thiab yooj yim rau kev tsim. Yas phaj muaj cov dej tsis zoo thiab corrosion tsis kam, tab sis tsis muaj zog thiab tsis yooj yim los tiv thaiv qhov kub thiab qhov cuam tshuam sab nraud.
 Cov iav fiberglass phaj
Cov iav fiberglass phaj yog cov khoom siv insulating zoo heev nrog cov khoom zoo heev thiab kev tiv thaiv corrosion. Nws tuaj yeem ua tau raws li qhov xav tau ntawm cov hluav taws kub, noo noo thiab corrosion ntawm cov khoom siv hloov pauv, tab sis nws yog kim thiab yuav tsum muaj cov cuab yeej tshaj lij thiab kev ua haujlwm.
 Cov khoom siv sib xyaw
Cov ntaub ntawv sib xyaw yog tsim los ntawm ntau yam khoom siv thiab tuaj yeem coj mus rau ntau yam kev ua tau zoo, xws li lub zog, conductivity, corrosion resistance, nplaim retardancy, thiab lwm yam. Cov ntaub ntawv sib xyaw yog qhov nyuaj rau kev tsim khoom thiab kuj kim heev.
 Steel-aluminium composite phaj
Steel-aluminium composite phaj yog ib qho kev sib xyaw ntawm stainless hlau thiab txhuas phaj. Nws muaj qhov corrosion kuj ntawm stainless hlau phaj thiab lub teeb thiab conductivity ntawm txhuas phaj. Nws yog haum rau loj thiab high-power hloov txee. Txawm li cas los xij, kev ua haujlwm ntawm steel-aluminium composite phaj yog qhov nyuaj thiab yuav tsum tau ua cov txheej txheem kev tshaj lij.
