Txheej txheem cej luam ntawm Ductile Iron Pipe
Ductile Iron pipes yog cov kav dej uas ua los ntawm cov khoom siv hlau. Ductile hlau yog spheroidized graphite cam khwb cia hlau. Cov qib siab ntawm kev cia siab ntawm cov khoom siv hlau yog feem ntau vim nws lub zog siab, ua haujlwm ntev, thiab cuam tshuam thiab corrosion kuj. Cov kav hlau kav dej feem ntau yog siv rau kev faib dej thiab siv cov slurries, dej phwj tuaj thiab txheej txheem tshuaj. Cov kav hlau hlau no yog kev txhim kho ncaj qha ntawm cov kav hlau cam ua ntej uas nws tau tam sim no yuav luag hloov. Cov qib siab ntawm kev cia siab ntawm cov kav hlau yeeb nkab yog vim nws cov khoom zoo heev. Cov kav dej no yog cov kav dej uas nrhiav tau tshaj plaws rau ntau daim ntawv thov.

Peb Cov Qib Tseem Ceeb ntawm Casted Iron Pipe
V-2 (chav kawm 40) Grey Iron, V-3 (65-45-12) Ductile Iron, thiab V-4 (80-55-06) Ductile Iron. Lawv muab lub zog compression zoo heev thiab muaj peev xwm vibration dampening.
V-2 (chav kawm 40) Grey Iron, ASTM B48:
Qib no muaj lub zog tensile siab ntawm 40,000 PSI nrog compression zog ntawm 150,000 PSI. Nws hardness ranges ntawm 187 - 269 BHN. V-2 yog qhov tsim nyog rau kev siv ncaj qha thiab muaj lub zog siab tshaj plaws, hardness, tsis kam hnav thiab kub kho cov lus teb rau cov hlau tsis muaj hlau. Nws yog dav siv rau kev siv bearing thiab bushing hauv kev lag luam hydraulics.
V-3 (65-45-12) Hlau Hlau, ASTM A536:
Qib no muaj lub zog tensile ntawm 65,000 PSI, yield zog ntawm 45,000 PSI, nrog 12% elongation. Lub hardness ntawm 131-220 BHN. Nws cov qauv zoo ferritic ua rau V-3 qhov yooj yim machining ntawm peb qib hlau ua rau nws yog ib qho ntawm cov machiniability superior cov qhab nia ntawm lwm cov ntaub ntawv ferrous; tshwj xeeb ua ke nrog kev pom kev cuam tshuam, qaug zog, hluav taws xob conductivity thiab magnetic permeability zog. Cov Hlau Hlau, tshwj xeeb tshaj yog cov kav dej, feem ntau yog siv rau cov kav dej thiab cov kav dej phwj tuaj. Cov hlau no kuj pom muaj nyob rau hauv cov khoom siv tsheb thiab kev lag luam.
V-4 (80-55-06) Hlau Hlau, ASTM A536:
Qib no muaj lub zog tensile ntawm 80,000 PSI, yield zog ntawm 55,000 PSI thiab elongation ntawm 6%. Nws yog lub zog siab tshaj plaws ntawm peb qib, raws li cam khwb cia. Qib no tuaj yeem kho cua sov rau 100,000 PSI tensile zog. Nws muaj 10-15% qis machiniability ntsuam xyuas dua V-3 vim nws cov qauv pearlitic. Nws yog feem ntau xaiv thaum steel lub cev xav tau.
DI Pipes zoo dua cov kav hlau / PVC / HDPE
• DI Pipes tseem txuag cov nqi khiav lag luam hauv ntau txoj hauv kev suav nrog cov nqi siv hluav taws xob, cov nqi tapping, thiab kev puas tsuaj los ntawm lwm yam kev tsim kho, ua rau tsis ua haujlwm thiab cov nqi kho feem ntau.
• Cov nqi ntawm lub neej ntawm DI Pipes yog ib qho txiaj ntsig zoo tshaj plaws. Txij li nws kav ntev mus rau tiam neeg, yog kev lag luam, thiab yooj yim thiab siv tau zoo thiab ua haujlwm, nws cov nqi mus sij hawm ntev lossis kev ua neej nyob tau yooj yim qis dua lwm yam khoom siv.
• Cov yeeb nkab hlau hauv nws tus kheej yog 100% cov khoom siv rov ua dua tshiab.
• Nws muaj zog txaus los tiv taus cov xwm txheej hnyav tshaj plaws, los ntawm kev siv lub zog siab, mus rau lub ntiaj teb hnyav thiab kev thauj mus los, mus rau cov av tsis ruaj khov.
• Kev teeb tsa yooj yim thiab nyab xeeb rau cov neeg ua haujlwm uas tuaj yeem txiav thiab coj mus rhaub Cov Yeeb Nkab Hlau rau ntawm qhov chaw.
• Cov yam ntxwv ntawm cov yeeb nkab Iron Pipe txhais tau hais tias cov yeeb nkab tuaj yeem yooj yim nyob hauv av nrog cov khoom siv cov yeeb nkab.
•DI kav dej muaj lub zog tensile siab dua li cov hlau me me thiab khaws cov khoom siv los ntawm cov hlau cam khwb cia.
