### 1. Dab tsi yog qhov sib txawv ntawm square thiab hloov cov yeeb nkab steel?
Thawj qhov sib txawv ntawm lawv tus ntoo khaub lig - seem ntawm cov duab, uas ua rau cov qauv sib txawv thiab cov ntawv thov.
* ** Dua cov yeeb nkab puag ncig: ** Muaj ib puag ncig hla - seem. Nws yog inherently ua kom muaj zog tiv thaiv ib qho kev nyuaj siab los ntawm txhua cov lus qhia, ua kom zoo tagnrho rau cov kua thauj (xip, pipelines) thiab cov ntawv thov yuav tsum tau siv lub zog siab (sib ntswg) lub zog. Nws tseem yooj yim dua rau khoov tsis muaj kinking.
* ** Square Yeeb Nkab: ** muaj ib lub tiaj tiaj, xwm fab xwm txheej - seem. Nws cov tiaj tiaj ua rau nws yooj yim dua rau weld, ntsia liaj qhov rooj, thiab txuas rau cov phiaj tiaj lossis lwm cov qauv. Nws muaj qhov siab dua mus rau khoov rau hauv ib qho kev taw qhia (los ntawm tiaj tus (los ntawm cov tiaj tiaj) thiab yog ntau dua pawg tau thiab ruaj khov rau kev cia. Nws yog feem ntau siv rau cov qauv txheej txheem, txhawb nqa, thiab ua laj kab.

### 2. Peb Hom Hlau Hlau Yog Dab Tsi?
Cov yeeb nkab steel tuaj yeem faib ua ntau hom kev, tab sis peb hom kev sib xws ntawm kev tsim khoom yog:
1. ** Ua Seamless Yeeb: ** Ua los ntawm cov khoom me me hlau Billet uas yog rhuab thiab chob los ntawm lub chaw uas tsis muaj nqaws lossis welds. Nws muaj zog dua thiab ntau txhim khu kev qha rau high- qhov kev thov siab (piv txwv li roj thiab roj thiab cov roj av, tshuab hydraulic).
2. ** WELDED YEEB (ERW): ** Tsim los ntawm dov ib lub raj hlau tiaj (skelp) rau hauv lub raj thiab vuam cov leeg ua ke, feem ntau siv cov hluav taws xob vuam (ERW). Nws yog ntau tus nqi -}} siv rau qis - hillaging zoo li cov dej, fencing, thiab siv cov qauv txheej txheem.
3. ** Galvanized Yeeb: ** Qhov no tsis yog hom kev tsim khoom tab sis ua tiav cov txheej txheem. Nws hais txog cov yeeb nkab steel (uas tuaj yeem yog seamless lossis welded) uas tau muab tso nrog ib txheej ntawm zinc los tiv thaiv nws ntawm corrosion. Nws yog yooj yim pom los ntawm nws cov nyiaj, crystalline- zoo li cov qauv, tes, thiab cov dej pabcuam.

### 3. Dab tsi yog cov duab ntawm cov yeeb nkab steel?
Thaum lub sij hawm feem ntau muaj thiab cov qauv txheem rau cov yeeb nkab steel yog ** ncig (ncig) **, nws yog tsim nyob rau hauv ntau cov duab. Cov duab nquag muaj xws li:
* Puag ncig (ncig)
* Square
* Cov plaub hau
Lwm yam cov duab tsawg dua yog oval, elliptical, thiab txawm tias kev cai kev lag luam zoo.

### 4. Dab tsi yog qhov sib txawv ntawm cov yeeb nkab ncaj thiab duab sib dhos?
Qhov no zoo ib yam li cov xwmfab vs. Hloov kev sib piv, tsom mus rau lub tiaj tiaj - eded cov duab sib dhos.
* ** Roundrular Yeeb Nkab: ** Muaj lub zog muaj zog nyob rau hauv txhua cov lus qhia thiab yog qhov ua tau zoo heev ntawm muaj kev nce sab hauv. Nws yog tus qauv rau kev txav roj av thiab kua. Nws txoj kev nkhaus yog qhov yooj yim rau cov kev sib txuas tiaj.
* ** HLOOV HLAU: ** muaj ob sab ntev thiab ob sab tsheb luv. Nws muab cov siab tiv thaiv rau khoov hauv nws cov xim muaj zog (qhov yooj yim dua) thiab yog qhov yooj yim heev los sib xyaw ua ke, cov vaj tse, thiab thav ntawv. Nws yog feem ntau xaiv rau cov vaj tse tsim vajtse thiab kev zoo nkauj, xws li cov qauv tuav niaj hnub thiab cov khoom lag luam muaj zog, qhov twg yog qhov zoo tshaj plaws, Sleek saib yog qhov xav tau.

### 5. Qhov twg muaj zog dua cov yeeb nkab lossis cov yeeb nkab sib txawv?
"Muaj zog dua" yog nyob ntawm hom kev thauj khoom thov.
* ** Rau torsional (twisting) loads: ** A ** ROUND yeeb nkab ** yog muaj zog dua. Nws cov duab sib txawv muab cov uniform tsis kam rau torsion.
* ** Rau dabtsi yog khoov loads (los ntawm ib qho kev taw qhia tshwj xeeb): ** Square Yeeb Nkab "feem ntau muaj qhov hnyav me ntsis thaum lub nra tau thov mus rau nws lub ntsej muag tiaj tus. Qhov no ua rau nws pib tiv taus kev khoov rau hauv qhov kev taw qhia tshwj xeeb.
* ** TXHEEJ TXHEEM TXHEEJ TXHEEM: ** ROIN ROIDE muaj zog dua * rau nws qhov hnyav dua vim nws muaj qhov muaj zog tshaj ob qho kev khoov thiab Buckling los ntawm ntau cov lus qhia.
Hauv cov ntsiab lus: puag ncig muaj zog rau torsion thiab tag nrho cov xwm txheej, thaum square tuaj yeem muaj zog rau kev tshwj xeeb, kev puas yog khoov.
