Txheej txheem cej luam ntawm ciaj ua hlau yeeb
Zas Cov Kav Hlau yog cov kav dej ua los ntawm cov hlau coo. Ntiav hlau yog spheroidized graphite pov cov hlau. Cov qib siab ntawm cov av ductab yog feem ntau yog vim nws lub zog siab, durability, thiab kev cuam tshuam thiab corrosion tsis kam. Zas cov kav hlau ib txwm siv rau kev faib dej ua dej muaj txiaj ntsig thiab tso dej ntawm slurries, dej phwj thiab ua tshuaj lom. Cov kav dej hlau yog kev txhim kho ncaj qha ntawm kev ua ntej cam khwb cia hlau kav uas nws tau tam sim no yuav luag hloov. Qib siab ntawm kev vam meej ntawm cov kav hlau zas yog vim nws ntau yam khoom zoo dua. Cov kav dej no yog qhov tseem nrhiav tau tom qab kav rau ob peb daim ntawv thov.

Peb qib tseem ceeb ntawm cov yeeb nkab hlau
V-2 (chav kawm 40) hlau grey, v-3 (65-45-45-45-45-45-45-4-4-45 (80-55-55-06) ductile hlau. Lawv muab cov khoom siv compression zoo thiab muaj peev xwm dampening muaj peev xwm dampening muaj peev xwm.
V-2 (Chav 40) Hlau Hlau, ASTM B48:
Cov qib kawm no muaj lub zog loj ntawm 40,000 psi nrog lub zog tseem ceeb ntawm 150,000 PSI. Nws lub hardness ranges los ntawm 187 - 269 BTY. V-2 yog qhov zoo tshaj plaws rau kev ncaj ncees hnav cov ntawv thov thiab muaj lub zog tshaj plaws, hardness, tsis kam mus rau hnav thiab cua sov kho hlau. Nws yog dav siv rau cov kabmob thiab cov ntawv thov bushing hauv cov hydraulic kev lag luam.
V-3 (65-45-12) Cov Hlau Zas Hlau, Astm A536:
Cov qib kawm no muaj lub zog tensile ntawm 65,000 psi, paib lub zog ntawm 45,000 psi, nrog rau 12% elongation. Lub hardness ranges los ntawm 131-220 bhn. Nws zoo ferritic qauv ua rau lub v-3 qhov yooj yim machining ntawm peb hom qib ua nws ib qho ntawm cov qhab nia zoo tshaj plaws ntawm lwm cov ntaub ntawv ferrod; Tshwj xeeb sib xyaw ua ke nrog kev sib xyaw ua ke nrog kev sib txuam zoo, nkees, hluav taws xob conductivity thiab kev sib nqus permeability cov khoom lag luam. Zas cov hlau, tshwj xeeb tshaj yog cov kav dej, feem ntau yog siv rau dej thiab dej phwj. Cov hlau no tseem muaj nyob hauv cov ntawv thov hauv tsheb thiab kev siv khoom lag luam.
V-4 (80-55-06) Zas hlau, ASTM A536:
Cov qib kawm no muaj lub zog tensile ntawm 80,000 psi, tawm lub zog ntawm 55,000 psi thiab elongation ntawm 6%. Nws yog lub zog siab tshaj plaws ntawm peb qib, raws li cam khwb cia. Qhov kev kawm no tuaj yeem yog cov kho cua sov kom 100,000 psi tensile zog. Nws muaj 10-15% qis dua kev ntsuas ntsuas dua li V-3 vim nws cov qauv PETLITIC. Nws yog feem ntau xaiv thaum lub cev siv hlau hlau.
Cov kav dej di pipes zoo dua li steel / PVC / HDPE kav dej
• DI cov kav dej tseem txuag cov nqi kev ua haujlwm nyob rau hauv ntau txoj kev suav nrog cov nqi tso twj, thiab ua tau kev puas tsuaj los ntawm lwm yam kev tsim kho, ua rau tsis ua haujlwm thiab tus nqi kho kom haum.
• Nqi ntawm di kav yog ib qho ntawm nws cov txiaj ntsig zoo tshaj plaws. Txij li nws kav rau tiam neeg, yog kev lag luam ua haujlwm, thiab yooj yim thiab ua haujlwm, nws tus nqi ntev lossis lub neej ua tau yooj yim dua li lwm cov khoom siv.
• Zas cov yeeb nkab yeeb nkab hauv nws tus kheej yog 100% siv cov khoom siv.
• Nws muaj zog tiv tau cov kev mob hnyav tshaj plaws, los ntawm cov ntawv thov kev siab tshaj plaws, kom muaj zog hauv ntiaj teb thiab cov tsheb thauj khoom, kom tsis muaj av tsis khov.
• Kev teeb tsa yog qhov yooj yim thiab muaj kev nyab xeeb rau cov neeg ua haujlwm uas tuaj yeem txiav thiab coj mus rhaub cov hlau yeeb nkab rau ntawm qhov chaw.
• Cov hlau me me ntawm cov tshuab ua yeeb nkab hlau txhais tau tias cov yeeb nkab tuaj yeem yooj yim nyob hauv av nrog cov pa yeeb nkab hauv av.
•DI cov kav dej muaj cov tensile siab dua li cov hlau me dua li cov hlau me me thiab khaws cov inherent corrosion tsis kam ntawm cam khwb cia hlau.
