En 10255 gi cov yeeb nkab

Tianjin Linfe Industrial Co., Ltd yog ib qho kev paub txog cov neeg tsim thiab cov chaw muag khoom ntawm en 10255 gi cov yeeb nkab hauv Suav teb. Thov koj xav tau kev xav tau zoo rau 10255 gi yeeb nkab los ntawm peb lub hoobkas. Cov kev pabcuam zoo thiab tus nqi tsim nyog muaj.

En10025 GI Pipes sib xyaw ua ke cov hlau uas ua raws li cov txheej txheem hlau loj steel (GI)

Thaum ntsib txoj kev en10025 gi kav ntawm cov sib txawv sib txawv, koj tuaj yeem xav txog cov hauv qab no los xaiv qhov tsim nyog:

• Qhia kom meej rau daim ntawv thov cov xwm txheej:

Ua ntej, txiav txim siab lub hom phiaj tseem ceeb ntawm cov raj xa dej. Puas yog siv rau kev txhim kho tsev, kho tshuab tsim, lossis rau thauj cov kua xws li dej thiab roj? Cov kev siv sib txawv muaj cov kev ntsuas sib txawv ntawm lub zog, kev ua kom tawv, corrosion tsis kam thiab weldability ntawm kav dej.

• Ntsuam xyuas ib puag ncig siv:

Cov raj xa dej yuav zoo li cas? Nyob sab hauv tsev lossis sab nraum zoov? Koj puas tau nkag mus rau hauv kev sib cuag nrog corrosive media lossis tau nyob rau hauv lub siab - av noo ib puag ncig? Qhov no yog hais ncaj qha rau ntau npaum li cas corrosion - tiv taus galvanized txheej koj xav tau thiab seb koj puas yuav tsum xav txog cov tshiab hlau ua cov txheej txheem hauv EN10025-5.

• Txiav txim siab cov khoom siv tshuab:

Raws li tus tsim qauv, txiav txim siab tawm los lub zog (xws li S235, xws li cuam tshuam rau JR, J2, J2, thiab lwm yam) ntawm qhov yuav tsum tau pipeline.

• Xav Txog Kev Tsim Kho Tshuab:

Puas yog cov yeeb nkab yuav tsum tau ua ntxiv xws li puas yog khoov thiab vuam? Qhov no yuav tsum tau kom koj them sai sai rau cov pa roj carbon sib npaug (cev) los xyuas kom ntseeg tau zoo weldability thiab nws muaj peev xwm.

En10025 GI Yeeb sib xyaw ua ke rau En10025 Cov Qauv Steel nrog Galvanized Hlau (GI) ant {

Tus tub ntxhais ntawm EN10025 GI cov yeeb nkab dag nyob hauv ib txhij ntsib cov kev cai ntawmKhoom Siv Kev Ua Tauthiabanti - corrosion kev ua tau zoo.

• Hais txog EN10025 Txuj Ci:

EN10025 yog European txheem rau cov qauv hlau qauv, npog ntau ntu. Cov khoom siv uas nquag siv rau cov yeeb nkab gi tsis- ale allo style cov hlau hauv en 10025-2, xws li S235jr, thiab S355jr. Cov qib kawm muaj lub zog zoo thiab solderability. Tus qauv qhia kom meej meej stipulates cov tshuaj lom neeg muaj pes tsawg leeg (xws li cov khoom siv roj carbon (xws li muaj zog ntxiv, ua kom muaj zog ntxiv, tensile zog rm, elongation).

• Hais txog galvanization (GI):

Lub galvanized txheej yog tus yuam sij rau anti - corrosion. Muaj ntau txoj kev:

1. Pre6 - Galvanized:Cov kav dej tau ncaj qha dov thiab welded los ntawm galvanized steel ib daim. Cov txheej txheej zinc feem ntau yog cov nyias nyias, txog 40 mus rau 80 grams ib square meter.
2. Kub - dip galvanized: Galvanizing dub kav los ntawm raus lawv hauv Molten zinc. Lub zinc txheej yog cov tuab, feem ntau 200 rau 600 grams ib square {{3} corrosion muaj peev xwm thiab yog ntau ruaj khov.

• Lwm cov ntsiab lus qhia:

Rau cov kav dej, kev saib xyuas yuav tsum tau them rau qhov ntev ntev, xws li cov ntawv sib txuas zoo xws li kev ntsuam xyuas dej siab lossis kev ntsuam xyuas.

EN10025 GI Yeeb yog dav siv nyob rau hauv: Vim nws cov qauv teeb tsa thiab corrosion tsis kam

• Architecture thiab cov qauv tsim qauv:

Feem ntau siv nyob rau hauv cov qauv thav duab hlau ntawm cov chaw tsim khoom thiab cov chaw khaws khoom, cov trusses, kev tsim kho thiab cov neeg tiv thaiv, thiab lwm yam.

• Tsheb Thauj Mus Los:

Nws yog siv rau kev thauj cov dej xws li dej, roj av, thiab qis {{{{}} lub sam roj hluav taws xob, thiab lwm yam khoom siv thiab lwm yam.

• Hauv thaj teb kev tsim kho thiab kev lag luam:

Nws pabcuam ua tus muaj casing, nkhaus, thiab feem ntawm conveying system rau cov khoom siv kho txhua yam, thiab tseem siv nyob rau hauv cov khoom siv ntawm cov nroj tsuag tshuaj thiab kev lag luam min.

• Ua liaj / teb thiab Horticulture:

Feem ntau siv los ua cov qauv qauv rau lub tsev tsev cog khoom ua.

Lwm yam siv: nws kuj tseem tuaj yeem pom hauv cov chaw hloov chaw, lub cim tsheb sib tw, teeb lub teeb lub teeb, thiab lwm yam.

Thaum xaiv thiab siv En10025 GI Yeeb, muaj ob peb lub ntsiab lus uas xav tau kev saib xyuas tshwj xeeb:

1. Qhia kom meej:

Xaiv cov kev siv zinc tsim nyog ntawm cov galvanizing ntawm cov galvanizing raws li kev corrosiveness ntawm kev siv kev pab hauv ib puag ncig (sab nraud, huab cua ib puag ncig). Xaiv lub zog tsim nyog ua haujlwm (xws li S235jr) thiab phab ntsa tuab ntawm cov yeeb nkab raws li cov qauv tsim qauv.

2. Ua tib zoo rau Weldability:

Yog tias vuam yuav tsum tau, them sai sai rau cov pa roj carbon sib npaug (cev) ntawm cov hlau. Tus nqi siab CEV yuav cuam tshuam kev vuam ua haujlwm thiab nce kev pheej hmoo ntawm kev tawg.

3. Xyuas cov ntaub ntawv zoo:

Thaum kev yuav khoom, thov cov ntawv pov thawj ntawv (MTC) los ntawm tus xa khoom kom ntseeg tau tias cov khoom lag luam ua raws li cov kev xav tau. Ib feem peb -} Kev tshuaj xyuas tog yuav thov thaum tsim nyog.

4. Cia thiab Plahaum:

Sim ua kom tsis txhob ua pob thiab ua kom puas rau cov txheej zinc. Yog hais tias lub zinc txheej kos tau kos, nws yuav tsum tau kho nyob rau hauv lub sij hawm nrog tshwj xeeb zinc {{1} Rich Corrosion Pleev xim kom tswj tau tag nrho cov tshuaj tiv thaiv corrosion- corrosion nyhuv.

EN10025 Gi cov yeeb nkab yog cov khoom lag luam hlau uas sib txuas lus thiab anti anti {1} Corrosion muaj peev xwm, thiab yog qhov yuav tsum muaj zog.
