• Kev kub siab kuj: Cov txheej txheem duplex stainless hlau ruaj khov nyob ruaj khov rau cov boilers thiab kev hloov cua sov.

Stainless Hlau Hollow Profiles yog dav siv nyob rau hauv cov teb hauv qab no vim tias lawv cov khoom muaj kev nkag siab:

• Vaj tse thiab cov choj: xws li ntaub pua rooj sib xyaw phab ntsa txhawb nqa qauv phab ntsa (ultra
• Neeg kho tshuab tsim: Raws li lub tshuab hluav taws xob hydraulic, neeg hlau pob txha, thiab lwm yam, yuav tsum tau tiv thaiv cov thauj khoom siab thiab muaj kev ntxhov siab.
• Zog thiab cov tshuaj lom neeg: Kev sib pauv cov leeg yas, cov hlab ntsha tsis kam rau corrosion tsis kam thiab kub tsis kam.
• Kev kho mob thiab khoom noj: huv si stainless hlau leeg yog siv los thauj cov kua dej tsis muaj menyuam lossis cov khoom noj muaj zaub mov.
• Kev tsim kho ib puag ncig: loj-licia phwj kav dej kav thiab dej hiav txwv dealishing, tiv taus corrosive kev tawm xov xwm.
