Kev taw qhia los ntawm lub tswv yim ntawm ntsuab thiab qis- kev txhim kho cov pa roj carbon monoxide, kev tsim kho thiab kev txhim kho hauv nroog hauv nroog tau nce ntxiv hais txog eco-kev phooj ywg thiab lub neej- kev ua haujlwm ntawm cov khoom siv.Ductile hlau yeeb nkab fittings, nrog rau lawv cov khoom zoo heev, durability, thiab recyclability, ua kom pom qhov tseem ceeb ntawm daim ntawv thov nyob rau hauv ntsuab municipal engineering. Qhov tseem ceeb hauv paus ntsiab lus txhawb nqa kev tsim kho nroog kom ruaj khov.
Cov yeeb nkab hlau fittings yog tsim los ntawm spheroidal graphite cam khwb cia hlau ua cov khoom siv hauv paus, los ntawm precision casting thiab tiv thaiv - kev kho corrosion. Lawv lub zog thiab toughness yog deb tshaj li cov tsoos grey cam khwb cia hlau, nrog tensile lub zog ncav cuag 400-900 MPa thiab elongation ntawm 2% -10%. Lawv tuaj yeem nyob ruaj khov nyob rau hauv cov khoom hnyav thiab qhov sib txawv ntawm qhov kub thiab txias, txo qis kev hloov pauv thiab kev siv peev txheej vim tawg lossis deformation ntau dhau. Qhov kev ntseeg siab ncaj qha txuas mus rau lub neej kev pab cuam ntawm cov kav xa dej, txo cov pa roj carbon emissions thiab cov khoom pov tseg thaum lub sij hawm tsim kho thiab ua haujlwm, thiab ua raws li cov kev cai ntawm cov vaj tse ntsuab kom ntev - kav ntev thiab ruaj khov.
Nyob rau hauv cov nqe lus ntawm ib puag ncig adaptability, ductile hlau yeeb fittings yuav tsim ib tug ntom oxide tiv thaiv zaj duab xis nyob rau hauv tej yam ntuj tso dej thiab av media. Ua ke nrog sab hauv thiab sab nraud los tiv thaiv- cov txheej txheem corrosion (xws li cov cement mortar hauv ob sab phlu, epoxy resin txheej, thiab zinc- txhuas txheej), lawv tuaj yeem tiv thaiv corrosion ntawm noo noo, ntsev tsuag, thiab kua qaub thiab alkali impurities, tswj kev ua haujlwm ruaj khov nyob rau hauv ib puag ncig hnyav xws li cov kav dej hauv av, cov chaw ua si hauv hiav txwv, thiab cov chaw ua si. Lub neej ua haujlwm ntev txhais tau hais tias kev hloov pauv tsawg dua thiab kev siv hluav taws xob qis dua, pab txo qis kev tsim kho kev cuam tshuam thiab kev tsim khoom pov tseg, ntxiv rau kev ua kom zoo dua qub ntawm ecological hneev taw ntawm cov haujlwm hauv nroog engineering.
Kev tsim kho thiab kev siv cov peev txheej zoo sib xws yog qhov tseem ceeb. Cov yeeb nkab hlau fittings feem ntau yog siv lub qhov (socket), mechanical, lossis flange sib txuas, uas yooj yim rau nruab thiab tuaj yeem rov ua dua, ua kom lub sijhawm tsim kho thiab txo qis ntawm - qhov chaw siv hluav taws xob thiab nqi zog. Cov khoom nws tus kheej muaj zoo recyclability; Tom qab muab pov tseg, nws tuaj yeem smelted, txuag cov khoom siv hlau ore thiab txo kev siv hluav taws xob thiab emissions thaum lub sij hawm smelting. Qhov kev kaw no - tus yam ntxwv ntawm kev siv lub voj voog ua raws li cov hauv paus ntsiab lus ntawm kev lag luam ncig, muab kev lees paub rau qhov qis - carbon transformation ntawm municipal engineering tej yaam num thoob plaws tag nrho lawv lub neej voj voog.
Ua haujlwm tau zoo, cov yeeb nkab steel yeeb nkab fittings tuaj yeem siv dav hauv kev siv hauv nroog ntsuab xws li dej, dej, roj, cua sov, thiab kev tiv thaiv hluav taws. Lawv qhov kub ntawm qhov dav (-20℃txog li 350 degree) thiab kev ua haujlwm siab sealing kom muaj kev nyab xeeb thiab kev thauj mus los ntawm ntau yam xov xwm. Cov khoom siv tshwj xeeb xws li cov pob qij txha nthuav dav tuaj yeem ua rau cov thermal expansion thiab contraction, txhim kho kev ruaj ntseg thiab lub zog ua haujlwm. Los ntawm kev xaiv tsim nyog thiab kev teeb tsa, qhov sib npaug ntawm cov peev txheej engineering thiab cov txiaj ntsig ecological tuaj yeem ua tiav thaum ua kom muaj kev ruaj ntseg ntawm cov dej, kev tswj dej nag, thiab kev xa hluav taws xob huv thiab kev faib tawm.
Zuag qhia tag nrho, ductile hlau yeeb nkab fittings, nrog lawv cov txiaj ntsig zoo ntawm lub zog siab, ua haujlwm siab, kev tsim kho yooj yim, thiab rov ua dua tshiab, muab cov kev ntseeg siab thiab ib puag ncig kev phooj ywg hauv ntsuab municipal engineering. Nrog rau kev nce qib ntawm kev loj hlob hauv nroog tshiab thiab qis - cov tswv yim carbon, lawv qhov dav thiab qhov tob yuav nthuav dav ntxiv, muab kev txhawb nqa zoo rau kev tsim kom muaj kev nyab xeeb, lub zog -txuag, thiab kev ruaj ntseg hauv nroog.
