Cast Iron
Feem ntau grey cam khwb cia hlau los yog ductile hlau; tus nqi qis thiab kev ntxhib los mos; tsim nyog rau cov kav dej thiab cov pa xa hluav taws xob thiab cov khoom siv tiv thaiv hluav taws hauv tsev. Cov kev tsis zoo muaj xws li lub zog nruab nrab, muaj kev cuam tshuam rau xeb, thiab lub neej ua haujlwm luv dua.
Carbon Steel
Siab zog thiab zoo machinability; tuaj yeem galvanized los txhim kho corrosion kuj; muab tus nqi zoo heev -kev ua tau zoo. Haum rau feem ntau sab hauv tsev thiab sab nraum zoov tiv thaiv hluav taws thiab siv dej / dej siv; ua tau kev ntseeg siab nyob rau hauv ib puag ncig humid tsis muaj zog corrosive agents.
Stainless hlau
Feem ntau ua los ntawm qib 304 lossis 316L; nta zoo heev corrosion kuj thiab ib tug du nto uas resists fouling; ua tau raws li cov qauv kev nyiam huv. Haum rau kev ua zaub mov, tshuaj, tshuaj, thiab lwm yam kev siv uas yuav tsum tau ua kom huv huv lossis tiv thaiv corrosion; muab lub neej ua haujlwm ntev tab sis tuaj ntawm tus nqi siab dua.
Lwm yam khoom siv tshwj xeeb
Qee qhov loj - txoj kab uas hla, hnyav- qauv ua haujlwm siv cov hlau cam los yog DZ 20# steel ua ke nrog cov yas-coated los yog hmoov- coated tiav. Cov no yog tsim los rau siab - cov kev mob siab tshaj 2.5 MPa thiab feem ntau yog siv nyob rau hauv lub nroog utility tunnels thiab hnyav -duty industrial piping systems.
