Yuav ua li cas Malleable yeeb nkab fittings txawv ntawm Ordinary cam khwb cia hlau fittings?

Yuav ua li cas malleable yeeb nkab fittings txawv ntawm cov cam khwb cia hlau zoo tib yam?

Taw qhia:
Cov yeeb nkab fittings yog cov khoom siv tseem ceeb siv hauv cov kav dej los txuas cov kav dej lossis cov kav dej. Lawv tau tsim los pab txhawb cov dej ntws los yog cov pa roj los ntawm cov kav dej. Thaum muaj ntau hom yeeb nkab fittings muaj nyob rau hauv kev ua lag luam, tsab xov xwm no yuav tsom rau qhov sib txawv ntawm cov yeeb nkab fittings malleable thiab zoo tib yam cam khwb cia hlau fittings. **Malleable yeeb nkab fittings thiab zoo tib yam cam khwb cia hlau fittings txawv nyob rau hauv lawv muaj pes tsawg leeg, lub zog, raug txheej txheem, thiab haum rau ntau yam kev siv **. Kev nkag siab txog qhov sib txawv no tuaj yeem pab cov neeg siv kev txiav txim siab thaum xaiv cov fittings tsim nyog rau lawv cov kav dej xav tau.

Kev sib xyaw thiab muaj zog:
Malleable yeeb nkab fittings thiab zoo tib yam cam khwb cia hlau fittings txawv heev nyob rau hauv cov nqe lus ntawm lawv muaj pes tsawg leeg thiab lub zog. Cam khwb cia hlau fittings feem ntau yog ua los ntawm grey hlau, uas yog ib tug alloy feem ntau muaj li ntawm hlau, carbon, thiab silicon. Ntawm qhov tod tes, malleable fittings yog tsim los ntawm malleable hlau, uas yog ib hom cam khwb cia hlau uas muaj tsawg carbon thiab silicon tab sis ntau dua cov ferrite thiab pearlite. Qhov sib txawv ntawm qhov sib xyaw ua rau muaj qhov sib txawv ntawm cov hardness thiab lub zog.

Cam khwb cia hlau fittings, ua nkig ntau dua vim cov ntsiab lus carbon ntau dua, yog qhov zoo rau cov ntawv thov uas xav tau cov khoom siv ruaj khov tab sis tsis muaj kev ntxhov siab ntau dhau los yog txav mus los. Lawv feem ntau yog siv rau hauv cov kav dej, cov kav dej phwj tuaj, thiab cov ntawv siv tsis muaj zog. Malleable fittings, ntawm qhov tod tes, pom zoo ductility thiab tensile lub zog vim lawv cov ntsiab lus qis dua. Qhov no ua rau lawv zoo tagnrho rau cov ntawv thov uas muaj kev ntxhov siab, kev co, lossis kev txav mus los, xws li cov kav dej, cov kav dej, thiab cov txheej txheem kev lag luam.

Kev tsim khoom:
Lwm qhov sib txawv tseem ceeb nyob hauv cov txheej txheem tsim khoom ntawm malleable thiab cam khwb cia hlau fittings. Cam khwb cia hlau fittings feem ntau yog tsim los ntawm cov txheej txheem casting, qhov twg hlau molten yog poured rau hauv pwm thiab tso cai rau txias thiab solidify. Cam khwb cia hlau fittings tej zaum yuav muaj ib tug rougher nto tag vim cov xuab zeb pwm siv nyob rau hauv cov txheej txheem casting. Cov fittings no ces raug rau machining thiab tiav cov txheej txheem kom tau raws li qhov xav tau qhov ntev thiab qhov smoothness.

Malleable fittings, ntawm qhov tod tes, tau txais kev kho cua sov tshwj xeeb hu ua annealing. Annealing muaj cua sov cov fittings mus rau ib tug tshwj xeeb kub thiab ces cia lawv txias maj mam. Cov txheej txheem no pab hloov cov microstructure ntawm cov hlau, ua rau muaj zog ductility thiab zog. Lub annealed fittings kuj muaj ib tug smoother deg tiav piv rau cam khwb cia hlau fittings, ua rau lawv zoo dua rau cov kev siv uas ib tug zoo tsos yog xav tau, xws li pom cov kav dej sib txuas los yog kho kom zoo nkauj installation.

Haum rau kev siv sib txawv:
Qhov sib txawv ntawm kev muaj pes tsawg leeg, lub zog, thiab cov txheej txheem tsim khoom thaum kawg ua rau muaj kev hloov pauv hauv cov ntawv thov haum rau malleable yeeb nkab fittings thiab zoo tib yam cam khwb cia hlau fittings. Cam khwb cia hlau fittings, nrog lawv cov ntsiab lus carbon siab dua thiab ntau dua brittleness, yog qhov zoo tshaj plaws rau cov ntawv thov tsis muaj zog thiab ib puag ncig uas muaj kev ntxhov siab tsawg, txav mus los, lossis kev co. Lawv ua tau zoo hauv cov ntawv thov xws li tswj cov dej khib nyiab, dej phwj tuaj, lossis lwm yam dej uas tsis tuaj yeem siv tau.

Malleable fittings, ua kom muaj zog dua thiab ua kom muaj zog, feem ntau yog siv rau hauv cov tshuab siab, qhov uas lawv tuaj yeem tiv taus cov kev ntxhov siab cuam tshuam nrog cov kua dej siab lossis cov pa roj. Lawv tsim nyog rau ob qho tib si dej kub thiab dej txias, kev faib hluav taws xob, cov kab cua compressed, thiab cov txheej txheem kev lag luam uas koom nrog kev thauj cov dej hauv qab. Malleable fittings 'muaj peev xwm tiv thaiv kev vibration los yog txav tau kuj ua rau lawv haum rau cov ntawv thov hauv ib puag ncig uas cov kav dej raug nthuav tawm, kev cog lus, lossis kev ntxhov siab.

Xaus:
Nyob rau hauv xaus, malleable yeeb nkab fittings thiab zoo tib yam cam khwb cia hlau fittings sib txawv nyob rau hauv lawv cov muaj pes tsawg leeg, lub zog, raug txheej txheem, thiab haum rau ntau yam kev siv. Cam khwb cia hlau fittings, nrog rau lawv cov ntsiab lus carbon siab dua thiab brittleness, yog qhov zoo tagnrho rau cov ntawv thov tsis muaj kev ntxhov siab thiab ib puag ncig uas muaj kev ntxhov siab tsawg lossis txav mus los. Malleable fittings, nrog rau lawv cov ntsiab lus qis carbon thiab nce ductility, muaj lub zog zoo dua thiab tsim nyog rau cov tshuab ua haujlwm siab thiab ib puag ncig nrog kev ntxhov siab, kev co, lossis kev txav. Thaum xaiv cov yeeb nkab fittings rau cov kav dej, nws yog ib qho tseem ceeb kom xav txog cov kev cai tshwj xeeb ntawm daim ntawv thov thiab xaiv cov fittings tsim nyog raws li.
