Yeeb nkab yeeb nkab yog nyob rau hauv cov tub ntxhais ntawm kev siv vaj tse, cov vaj tse thaj chaw, thiab cov loj {{| ntsuas txoj haujlwm. Thaum cov kav dej tau tsim los ua kom ntev rau xyoo tas los, ib qho ntawm feem ntau cov kev sib tw ntsib thoob plaws kev lag luam yogYeeb Nkab NyiasCov. Kev xau tsis yog cuam tshuam rau kev ua haujlwm tab sis kuj tuaj yeem ua rau siv tau kev tsim kho, phom sij, thiab cov khoom siv khib nyiab. Ntawm cov laj thawj ntau yam tom qab tsis muaj teeb meem, ob qho ntawm cov ntsiab lus tseem ceeb tshaj plaws yogKhoom Zoothiabib puag ncig ib puag ncigCov. Nkag siab tias cov khoom tsis ua yeeb yam tsis ua tau tuaj yeem pab cov engeters, cov neeg yuav tau txiav txim siab thaum xaiv cov kav hlau hlau xws liERW kav, carbon cov kav hlau, thiab hlau kav hlau me me.
Qhov tseem ceeb ntawm cov yeeb nkab khoom zoo
Qhov zoo ntawm cov yeeb nkab cov ntaub ntawv ncaj qha rau nws tiv thaiv nws txoj kev tiv thaiv, kev hloov pauv kub, thiab hnav tshuab. Cov kav dej tau tsim siv cov txheej txheem tsis raug lossis cov txheej txheem tsis raug ntau dua yuav muaj peev xwm tsim kho kom dhau sijhawm. NtawmHUAYANG STEEFF YEEB NKAB, cov qauv kev xaiv thiab cov qauv kev tsim khoom siv tau nruj me ntsis tswj kom ntseeg tau tias txhua qhov yeeb nkab tswj xyuas cov qauv txheej txheem kev ntseeg siab.
High - Cov kav dej zoo tau raug ntxias kom nruj kev soj ntsuam rau lub zog tensile, hardness, thiab tshuaj lom neeg. Cov kev ntsuas no ua kom cov hlau tuaj yeem tiv thaiv cov chaw muaj kev lag luam tsis muaj kev txwv lossis tsim micro- cov kab nrib pleb uas tom qab tig mus rau hauv cov dej xau. Piv txwv li,ERW kavthiabRab pom kavtsim raws li cov qauv thoob ntiaj teb xws liASTM, API, thiab enXa tau zoo nyob ntev - lo lus kev ntseeg tau sib piv rau qhov tsis - cov qauv khoom.
Cov khoom tsis zoo los ntawm cov khoom tsis zoo
Cov kav dej ua nrog qis - qib lossis rov ua dua cov hlau feem ntau muaj cov impurities uas cuam tshuam rau lawv cov kev ua haujlwm tsis txaus ntseeg. Cov vuam tsis tiav, tsis sib thooj phab ntsa tuab, lossis cov galvanization tsis txaus ntxiv kom muaj kev pheej hmoo ntawm cov to. Hauv qab no yog cov xwm txheej nquag cuam tshuam nrog cov khoom siv tsis zoo thiab lawv cov kev rau txim uas muaj peev xwm:
| Qhov tsis xws luag hauv cov ntaub | Muaj peev xwm ua rau muaj kev sib tw |
|---|---|
| Tsis sib haum Phab Ntsa Thickness | Kev tsis sib haum siab muab faib ua cov kab nrib pleb |
| Impurities hauv kev sib xyaw cov hlau | Nce penneness thiab txo lub zog |
| Pluag vuam seams | Thaum ntxov to feakage ntawm pob qij txha thiab kev sib txuas |
| Tsis muaj kev tiv thaiv txheej | Ua kom nrawm corrosion thiab xeb |
| Cov Txheej Txheem Ntsuas Tsis Muaj Zog | Undetected tsis muaj zog cov ntsiab lus thaum ntau lawm |
Cov thawj coj ntawm cov neeg yuav khoom thiab cov thawj tswj haujlwm yuav tsum nco ntsoov xyuas kom cov kav dej lawv tsim cov tshuab tswj nruj zoo.
Cawv ntawm ib puag ncig cov khoom siv
Txawm tias cov kav dej tau ua nrog rau saum -}}}} Cov kev mob ib puag ncig tseem tuaj yeem cuam tshuam lawv qhov kev ua tau zoo thiab ua rau xau. Kev hloov dua tshiab, raug rau cov tshuaj corrosive, av zoo, thiab vaum txhua lub luag haujlwm tseem ceeb hauv cov kav dej.
Piv txwv li, cov raj xa khoom tau nruab rau hauv av hauv av acidic lossis alkaline cov av ntsej muag sai sai yog tias tsis tau siv kom raug. Ib yam li ntawd, kav dej raug rau cov tshuaj lim dej ib puag ncig lossis cov tshuaj muaj zog tsis txaus siab piv rau cov neeg siv hluav taws xob hluav taws xob. Paub cov kev ntxhov siab ib puag ncig thiab xaiv txoj cai tiv thaiv txheej txheem lossis tus qauv hlau yog qhov tseem ceeb los txo cov kev lom zem.
Corrosion thiab nws cov kev cuam tshuam
Ib qho ntawm feem ntau ib puag ncig ua rau xau yogkev ua cev tubCov. Thaum cov kav dej tau raug rau cov pa oxygen, noo noo, lossis tshuaj lom neeg, oxidation pib demrade cov hlau nto. Sij hawm dhau mus, xeb ua kom xeb tsis muaj zog lub tshuab
Cov pa roj carbon kav hlau, thaum muaj zog thiab raug nqi -}}}}}}} Zoo tshwj xeeb, yog qhov tsis yooj yim rau kev xeb yog tias tsis muaj kev tiv thaiv. Vim li no ntau kev lag luam sivgalvanized steel kavlos yog thov epoxy txheej txheem kom txuas tau ruaj khov. Ntawm Huayang, cov neeg yuav khoom xaiv los ntawm ntau cov coated thiab uncoated steel kav nyob ntawm cov kev xav tau ib puag ncig ntawm lawv cov phiaj xwm.
Qhov kub thiab kub variations
Cov kav dej yeej nquag tau hloov pauv hauv sab hauv siab thiab ntsuas kub. Tam sim ntawd nce hauv dej siab, hu uaTso dej rauj, tuaj yeem ua cov kav dej tsis muaj zog kom tawg ntawm pob qij txha lossis khoov. Ib yam li ntawd, huab cua sov heev - puas muaj cov kev mob siab los yog siab}} yuav ua rau cov hlau ua kom nthuav dav lossis cog lus. Rov ua dua cov thermal cycling muab kev ntxhov siab rau cov yeeb nkab phab ntsa, ua rau nkees nkees thiab kev lom zem.
Vim li noTeem 40 kav hlauThiab lwm yam qauv tuab cov pawg yog qhov tseem ceeb. Xaiv qhov tseeb phab ntsa thickness kom ntseeg tau tias cov yeeb nkab tuaj yeem tiv thaiv ob qho tib si sab hauv thiab sab nraud tsis muaj kev ua tsis tiav.
Kev sib txheeb ntawm kev ua tau zoo thiab ib puag ncig
Nws yog ib qho tseem ceeb kom nkag siab qhov ntawdCov khoom siv zoo thiab ib puag ncig feem ntau ua haujlwm ua ke los txiav txim siab seb puas yuav xau dejCov. Txawm tias cov yeeb nkab uas muaj zog tshaj plaws yuav swb yog tias raug rau ib puag ncig uas muaj ib puag ncig uas tsis muaj kev tiv thaiv kev tiv thaiv. Hloov siab, txawm tias ib puag ncig me me tuaj yeem ua rau xau yog tias cov yeeb nkab nws tus kheej yog tsim tau zoo.
Piv txwv li, siv tsawg {{- Zoo Welded Kave tsis yog qhia tsis muaj zog ntawm cov nqaj tsis muaj zog tab sis kuj tseem ua rau cov nqaj hlau tsis muaj xeb. Ntawm qhov tod tes, ib qho zoo {- Cov pa roj carbon steel nrog anti {{Corrosion txheej tuaj yeem ua rau muaj kev sib raug zoo hauv ntau xyoo.
Kev Tiv Thaiv Tiv Thaiv Tawm Tsam
Txhawm rau txo cov kev phom sij Qee qhov kev coj ua tseem ceeb muaj xws li:
Xaiv cov kav hlau hlau tsim raws liASTM, API, thiab En Cov Qauv.
Tshuaj XyuasTeem Yug 40 Cov Yeeb Nkab LojThiab xaiv qhov tseeb phab ntsa tuab rau cov ntawv thov siab.
Ua ntaub ntawv thovZinc Txheej, Epoxy, lossis lwm cov khaubncaws sab nraud povtseglos tiv thaiv corrosion.
UaKev Saib Xyuas Kev Ncaj NceesTxog thaum ntxov nrhiav tau ntawm kev xeb lossis tawg.
Txhim kho cov kav dej nrog cov kev tsim nyog thiab kev txhawb nqa kom txo qis kev ntxhov siab.
