1. Cov khoom siv qib thiab cov qauv kev ua haujlwm
Stainless hlau fittings yog haum rau lawv corrosion kuj thiab lub zog. Kev nkag siab txog cov qib khoom sib txawv yog thawj kauj ruam hauv kev ua kom muaj kev sib raug zoo ntawm qhov project.
304 / 304L Stainless hlau: Cov txheej txheem ntau tshaj plaws, muab kev tiv thaiv corrosion zoo heev rau ib puag ncig. Nws yog dav siv nyob rau hauv architectural decorations thiab kev thauj mus los. Raws li cov ntaub ntawv kev lag luam tsis ntev los no, 304 stainless nyias- cov kav dej uas muaj phab ntsa tsis pom muaj xeb hauv 3-xyoo kev kuaj pom sab nraum zoov, nrog lub zog tensile ntau dua lossis sib npaug li 520MPa.
316 / 316L Stainless hlau: Nrog rau qhov sib ntxiv ntawm molybdenum, qib no muaj kev tiv thaiv zoo rau chlorides thiab acidic ib puag ncig. Nws yog qhov kev xaiv zoo tshaj plaws rau thaj chaw ntug hiav txwv, cov nroj tsuag tshuaj, thiab siab - cov dej huv huv. Piv txwv li, 316L fittings tau pom zoo tshwj xeeb rau qis -kub cua sov tshuab nyob rau sab qaum teb huab cua vim lawv zoo heev tsis kam mus rau qis - kub corrosion.
Tshwj xeeb Alloys: Rau siab - kub thiab siab - cov ntawv siv siab, cov ntaub ntawv tshwj xeeb xws li 20G, 16Mn, thiab 12Cr1MoV yog siv hauv cov haujlwm xws li petrochemicals thiab lub zog tsim hluav taws xob.
2. Thawj hom thiab kev sib txuas yees
Kev ntseeg siab ntawm cov kav dej feem ntau nyob ntawm txoj kev sib txuas. Cov kev nce qib niaj hnub no tau hloov kev tsom xam los ntawm kev sib tsoo ib txwm siv mus rau kev sib txuas ua haujlwm zoo dua.
A. Nias -Fitting Types
Xovxwm-fitting thev naus laus zis tau hloov kho qhov nrawm thiab kev ntseeg tau.
Ob Chav Xovxwm (Daim Ntawv Xovxwm) Fittings: Siv cov cuab yeej hydraulic, cov khoom siv thiab cov yeeb nkab raug kaw ua ke, tsim cov tshuab foob. Cov thev naus laus zis no tau raug pov thawj los tiv thaiv 1.6MPa dej siab yam tsis muaj qhov xau, ua rau nws zoo tagnrho rau siab - siab tiv thaiv hluav taws.
Ntiv Nplhaib Fittings: Siv cov txheej txheem txias extrusion, cov yeeb nkab kawg yog deformed rau embed rau hauv lub sealing zawj. Txoj kev no muab cov khoom sib khi zoo ib yam nrog kev tiv thaiv - rub quab yuam ntau tshaj 1500N, kom ntseeg tau ntev - lub sij hawm ruaj khov.
B. Grooved Fittings
Grooved fittings yog tus qauv rau loj - txoj kab uas hla. Lawv tshem tawm qhov xav tau ntawm vuam, yog li tsis txhob vuam cov pa taws thiab hluav taws kub.
Qhov zoo: Kev txhim kho kev ua tau zoo yog txhim kho los ntawm 40% piv rau cov tsoos vuam. Lawv siv EPDM roj hmab ntsaws ruaj ruaj uas muaj peev xwm tiv taus qhov kub ntawm -40℃txog 120 degree, haum rau kev tiv thaiv hluav taws thiab HVAC systems.
C. Flanges
Flangesyog qhov tseem ceeb rau kev sib txuas cov kav dej rau cov khoom siv los yog cov khoom siv. Cov tuam txhab ua lag luam tsim cov flanges hauv ntau cov ntaub ntawv (xws li 20G, 16Mn) kom tau raws li cov kev cai tshwj xeeb hauv kev lag luam roj thiab roj.
3. Cov ntawv thov tseem ceeb thiab kev pom kev lag luam
Stainless hlau fittings pab ib tug dav spectrum ntawm sectors, txhua yam uas nws xav tau.
Kev tiv thaiv hluav taws thiab cua sov
Lub durability ntawm fittings hauv cov tshuab no yog qhov tseem ceeb.
Kev sib tw Corrosion: Kev txheeb xyuas qhia tau tias 32% ntawm cov hluav taws xob xa hluav taws xob sib tsoo tshwm sim los ntawm qhov tsis txaus corrosion ntawm fittings, thiab 26% ntawm cov cua kub tsis ua haujlwm yog vim kev laus thiab xeb.
Kev daws: Replacing traditional carbon steel (which has a lifespan of 5-8 years) with stainless steel solutions (lifespan >70 xyoo) txo tus nqi txij nkawm los ntawm 75%. Piv txwv li, Nanjing Metro Kab 10 qhov hluav taws xob kho dua tshiab tau siv 304 stainless hlau xovxwm fittings los tawm tsam cov av av av, ua tiav xoom tsis ua haujlwm dhau 3 xyoos.
Municipal thiab Architectural Engineering
Hauv cov phiaj xwm hauv nroog, kev zoo nkauj thiab kev ncaj ncees ntawm cov qauv sib koom tes.
Daim ntawv thov: Kev sib cais ntawm txoj kev thaiv, choj guardrails, thiab lub tsev tuav.
Kev kho kom haum: Cov neeg muab khoom tam sim no muab siab -precision customization rau nyias- cov kav dej uas muaj phab ntsa, nrog rau sab nraud ntawm 6mm mus rau 219mm thiab kam rau ua tswj nyob rau hauv ± 0.03mm kom haum cov qauv tsim vaj tsev.
Kev siv dej haus thiab kev huv huv
Nrog cov kev cai nruj dua ib puag ncig, cov khoom siv rau cov dej haus yuav tsum ua raws li cov qauv kev nyiam huv. Cov khoom lag luam yuav tsum dhau qhov kev ntsuam xyuas kev nyab xeeb rau cov dej haus. Ob daim ntawv pov thawj ISO14001 ib puag ncig kev tswj hwm thiab cov ntawv tso cai tshwj xeeb hauv lub tebchaws tam sim no yog cov qauv tsim nyog rau cov neeg xa khoom raws cai.
4. Kev Tshawb Fawb thiab Kev Ua Raws Cai rau xyoo 2026
Thaum muab khoomstainless hlau yeeb nkab fittings, tshwj xeeb tshaj yog rau cov haujlwm thoob ntiaj teb, xav txog cov kev ua raws li hauv qab no:
Ntawv pov thawj Barriers: Cov ntaub ntawv luam tawm thoob ntiaj teb qhia tau hais tias 42% ntawm kev txiav txim raug txwv vim tsis muaj lub hom phiaj kev ua lag luam ntawv pov thawj. Cov ntawv pov thawj tseem ceeb suav nrog:
EU: CE Daim Ntawv Pov Thawj
Teb chaws USA: UPC ntawv pov thawj
Australia: WaterMark Certification.
Eco-Kev ua raws cai: Ua raws li REACH cov cai (txheej txheem ntau dua 1000 yam phom sij) yog qhov yuav tsum tau xa tawm mus rau Tebchaws Europe [[2]].
Muaj peev xwm muab khoom: Evaluate suppliers based on their ability to provide third-party testing data, inventory scale (e.g., >1000㎡ tiav warehouses), thiab cov ntaub ntawv tshwj xeeb xws li subway lossis tsev kho mob tej yaam num.
Xaus
Stainless hlau yeeb nkab fittings muab unmatched durability thiab versatility. Txawm hais tias rau kev tiv thaiv hluav taws tseem ceeb lossis cov ntawv thov kev tsim vaj tsev zoo, kev hloov pauv mus rau qib siab - cov ntaub ntawv qib siab xws li 316L thiab cov kev sib txuas siab tshaj plaws xws li xovxwm thiab zawj thev naus laus zis txhais cov qauv kev lag luam. Los ntawm kev ua ntej cov ntaub ntawv pov thawj thiab hom kev sib txuas tsim nyog, cov neeg muaj feem cuam tshuam tuaj yeem ua kom muaj kev nyab xeeb thiab siv tau ntev ntawm lawv cov kav dej.
