### 1. Kuv yog dab tsi "sws" txhais tau?
"Ssaw" sawv rau ** Kauv submerged arc welded ** {}}}} nws siv cov submerged arc vuam (pom) txheej txheem.

### 2. Cov yeeb nkab ssaw yog dab tsi?
Ib tug ** ssaw Yeeb (muab kauv subwerged arc welded yeeb nkab) ** yog cov kauv vuam ib ncig ntawm cov roj av hauv lub ntsej muag (pip)} Vim yog lawv txoj kab uas diameters loj thiab lub zog .

### 3. Dab tsi yog qhov sib txawv ntawm ERW & Seamless Yeeb Nkab?
- ** ERW (hluav taws xob tiv thaiv welded) yeeb nkab: **
- Ua los ntawm dov hlau coils rau hauv ib lub cylindrical puab thiab vuam lub seam siv hluav taws xob siv hluav taws xob.
- tsis muaj cov muab tub lim hlau siv hauv vuam .
- feem ntau pheej yig dua thiab haum rau cov ntawv thov tsawg rau-nruab nrab nruab nrab {}}
- pom weld seam, uas tuaj yeem yog qhov tsis muaj zog yog tias tsis kho kom raug kho.
- ** SEAMLESS YEEB: **
- Ua los ntawm extruding ib qho khoom noj billet rau hauv lub raj hollow tsis muaj vuam .
- Tsis muaj nqaws, muab cov khoom sib txuam zoo thiab cov siab zoo tshaj plaws .
- kim kim tab sis zoo tagnrho rau kev siab siab, siab-ntsuas kub (e {} g}, roj, tshuaj tsuag cov nroj tsuag).

### 4. Cov yeeb nkab dsaw yog dab tsi?
A ** DSAWW cov yeeb nkab (ob npaug subderged arc Welded yeeb nkab) ** Yog ob zaug (sab hauv) txheej txheem (sab hauv
- ** Longitudinal Dsaw (LSAWW): ** LUB CAIJ NTUJ: ** LUB CAIJ NTUJ: ** LUB CAIJ DUA) Raws li qhov ntev ntawm cov yeeb nkab .
- ** KAUV DSAW (SSAW): ** Cov khaub hlab khaub hlab ib ncig ntawm cov yeeb nkab .
DSAW Kav tau paub txog lub zog siab thiab siv nyob rau hauv cov ntawv thov xav tau xws li roj & roj kis {}}

### 5. Dab tsi yog qhov sib txawv ntawm dsaw thiab lsaw?
- ** DSAW (Ob Chav Submerged Arc Welded): **
- tuaj yeem yog ** ntev ntev (LSAWWRY (LSAW) ** lossis ** KAUV (SSAW) ** .
- welded ** ob zaug ** (sab hauv & sab nraud) rau lub zog siab dua .
- siv rau cov kab uas loj loj, cov raj luj taws siab .
- ** LSAWW (Longitudinal submerged Arc Welded): **
- A ** Hom DSAW ** Qhov twg Weld leeg khiav ncaj nraim raws cov yeeb nkab ntev .
- Ua los ntawm dabtsi yog khoov hlau hlau thiab vuam lub longitudinal seam .
- muaj zog tshaj li ERW tab sis feem ntau kim dua .
- feem ntau siv nyob rau hauv cov roj & roj, txheej txheem, thiab cov ntawv thov hnyav.
** TSEEM CEEB TSHUAJ: **
- ** LSAW-Seamed **, Thaum ** ** DSAWW tuaj yeem yog qhov ncaj (LSAWW) lossis KAUV) ** .
- ** DSAWW ** NTXIV TXOG ** OB CHAV VUAM Txheej Txheem **, Whereas ** Forgetudinal Seam Hom ** .
