Cov pa roj carbon steel
Nws yog steel alloyed feem ntau nrog carbon. Lub zog siab thiab hardness nce nrog cov ntsiab lus carbon, qis melting point, thiab ductility. Qhov no yog qib khoom siv tshaj plaws.
Hlau alloy
Nws yog steel alloyed nrog ib lossis ntau lub ntsiab lus uas hloov lossis txhim kho cov khoom ntawm cov hlau. Cov alloys muaj xws li chromium, molybdenum, nickel, vanadium, thiab manganese.
Stainless hlau
Nws yog hlau alloyed nrog chromium nyob rau hauv cov nyiaj saum toj no 10%. Chromium ua rau cov hlau tsis muaj steel muaj kev tiv thaiv corrosion ntau dua li cov hlau uas xeb tau yooj yim los ntawm huab cua thiab ya raws.
Cam khwb cia hlau
Hlau thaum nws yog alloyed nrog silicon, carbon, thiab ntau lwm yam alloys ua cam khwb cia hlau. Silicon rog carbon tawm ntawm cov hlau thiab tsim ib txheej graphite dub rau sab nrauv ntawm cov hlau. Cam khwb cia hlau muaj zoo machinability, castability, thiab fluidity.
Aluminium
Nws yog qhov tsawg-ceev, ductile, thiab malleable hlau nrog nruab nrab lub zog. Nws muaj kev tiv thaiv corrosion zoo dua piv rau lwm yam alloy thiab carbon hlau. Nws yog qhov tseem ceeb tshaj plaws thaum siv flange uas yuav tsum muaj qhov hnyav thiab lub zog.
tooj dag
Nws yog ib qho alloy ntawm zinc thiab tooj liab thiab feem ntau tuaj nrog cov ntsiab lus ntxiv xws li tin lossis txhuas. Nws yog tus cwj pwm los ntawm kev ua haujlwm zoo, txias ductility, high-temperature ductility, thiab lub zog zoo.
PVC
(Ceeb toom peb tsis muab cov ntaub ntawv qib polymer tab sis tau sau rau lawv rau koj cov txiaj ntsig hauv qab no)
Polyvinyl chloride los yog PVC yog ib qho thermoplastic polymer uas yooj yim sib sau ua ke, ruaj, thiab pheej yig. Nws yog resistant rau biological thiab tshuaj corrosion. Qhov sib ntxiv ntawm plasticizers ua rau nws yooj yim dua thiab mos.
Kev ua haujlwm nta
Cov yam ntxwv ua tau zoo yog cov khoom flange uas yuav nyob ntawm ntau lwm yam tab sis yog qhov tseem ceeb rau kev xav. Cov khoom muaj xws li cov hauv qab no:
Durability
Nws yog qhov toughness lossis lub zog ntawm cov yeeb nkab flange nyob rau hauv siab los yog kev ntxhov siab. Durability yog nyob ntawm flange compatibility thiab flange tsim nrog cov kav dej thiab cov khoom siv zog.
Yooj yim ntawm kev sib dhos
Nws yog ib qho kev ntsuas zoo ntawm qhov ua tau zoo ntawm cov txheej txheem disassembly thiab kev sib dhos. Rau cov ntawv thov nrog flange siv los kho lossis txuas ib ntus, qhov yooj yim ntawm kev teeb tsa thiab tshem tawm yog qhov tseem ceeb.
Qhov hnyav
Nws yog qhov hnyav lossis hnyav ntawm flange. Nws nyob ntawm cov khoom siv ntom ntom thiab loj. Cov neeg yuav khoom lag luam yuav tsum xav txog lub zog ntawm cov yeeb nkab lossis cov yeeb nkab txhawb nqa thaum ua haujlwm nrog cov flanges siab lossis loj-density.
