Tuam Tshoj Galvanized Tube Square Carbon Steel Yeeb Nkab

Galvanized yeeb nkab yog cov khoom siv hauv tsev uas muaj ntau yam kev siv. Txawm li cas los xij, vim yog ib puag ncig,cov kav hlauyog nquag xeb, deformation los yog puas thaum thauj. Yog li ntawd, nws yog ib qho tseem ceeb rau kev ntim khoom kom raug thiab thauj cov kav dej galvanized. Kab lus no yuav piav qhia yuav ua li cas ntim cov kav dej galvanized thaum thauj.

1. Ntim cov cai

(1). Qhov saum npoo ntawm cov yeeb nkab steel yuav tsum huv thiab qhuav, tsis muaj roj, plua plav lossis lwm yam khib nyiab.

(2). Cov yeeb nkab steel yuav tsum tau ntim nrog ob txheej txheej yas-coated ntawv, nrog rau txheej txheej txheej nrog cov ntaub yas nrog lub thickness tsis tsawg tshaj li 0.5 hli thiab cov txheej sab hauv them nrog pob tshab polyethylene yas zaj duab xis nrog lub thickness tsis tsawg tshaj li 0.02 hli.

(3). Cov yeeb nkab steel yuav tsum tau cim tom qab ntim khoom. Cov ntsiab lus cim yuav tsum suav nrog cov qauv, specification, batch naj npawb thiab hnub tsim khoom ntawm cov yeeb nkab steel.

(4). Cov kav hlau yuav tsum tau muab faib thiab ntim raws li ntau pawg xws li cov lus qhia tshwj xeeb, qhov loj me, thiab qhov ntev kom yooj yim thauj khoom, tshem tawm thiab khaws cia.

2. Cov txheej txheem ntim khoom

(1) Ua ntej ntim cov yeeb nkab galvanized, qhov saum npoo ntawm cov yeeb nkab yuav tsum tau muab ntxuav kom huv si thiab qhuav kom tsis txhob xeb thiab lwm yam teeb meem thaum lub sij hawm thauj mus los.

(2) Thaum ntim cov kav dej galvanized, yuav tsum tau them nyiaj rau kev tiv thaiv cov kav hlau. Liab cork plywood yuav tsum tau siv los txhawb ob qhov kawg ntawm cov kav hlau kom tsis txhob deformation thiab kev puas tsuaj thaum ntim thiab thauj.

(3) Cov khoom ntim ntawm cov kav dej galvanized yuav tsum tsis txhob ya raws, tsis muaj dej thiab xeb pov thawj kom ntseeg tau tias cov kav dej steel yuav tsis ntub los yog xeb thaum thauj.

(4) Tom qab ntim, cov kav dej galvanized yuav tsum tau tiv thaiv los ntawm ya raws thiab tshav ntuj kom tsis txhob raug tshav ntuj ntev los yog qhov chaw ntub dej.

3. Ceev faj

(1) Thaum ntim cov kav dej galvanized, yuav tsum tau them nyiaj rau tus qauv ntawm qhov loj thiab ntev kom tsis txhob khib nyiab thiab poob vim qhov loj me tsis sib haum.

(2) Tom qab ntim khoom, cov kav dej galvanized yuav tsum raug cim thiab muab faib rau lub sijhawm rau kev tswj hwm thiab khaws cia.

(3) Thaum ntim cov kav dej galvanized, yuav tsum tau them nyiaj rau qhov siab thiab ruaj khov ntawm cov khoom kom tsis txhob tilting lossis stacking siab dhau los ua kev puas tsuaj rau cov khoom. Cov saum toj no yog cov txheej txheem ntim ntawm cov kav dej galvanized thaum lub sijhawm thauj mus los, suav nrog kev ntim khoom, kev ntim khoom thiab kev ceev faj. Thaum lub sij hawm ntim thiab kev thauj mus los, cov kev cai yuav tsum nruj me ntsis ua raws li kev tiv thaiv cov kav hlau thiab xyuas kom cov khoom tuaj txog ntawm lawv qhov chaw nyab xeeb.
