### 1. Dab tsi yog qhov txawv ntawm ERW cov yeeb nkab thiab muab kauv yeeb nkab?
Tus yuam sij sib txawv lus dag nyob rau hauv kev taw qhia ntawm Weld Seam txheeb ze rau cov yeeb nkab lub axis.
** ERW (hluav taws xob tiv thaiv welded) yeeb nkab: ** Weld Seam yog ncaj thiab tig mus rau yeeb nkab lub axis. Nws yog tsim los ntawm kev tsim cov hlua khi ntawm cov hlau rau hauv ib lub cylindrical puab thiab tom qab ntawd vuam lub longitudinal seam siv hluav taws xob tsis siv hluav taws xob.
** Muab kauv yeeb (tseem hu ua hlaw oraw): ** Weld Seam yog nyob hauv ib tug kauv lossis helical los yog helical ib ncig ntawm cov yeeb nkab. Nws yog tsim los ntawm coiling ib sawb ntawm cov hlau ntawm kaum sab xis thiab txuas ntxiv vuam cov leeg ua kom zoo.
Lub ntsiab cuam tshuam yog:
* ** ERW ** Feem ntau yog siv rau me dua mus rau nruab nrab diameters thiab yog qhov ua tau zoo heev rau siab {}}} nplej ntau lawm ntawm cov qauv ntau thiab tsawg.
* ** KAUV HLAU ** yog qhov zoo dua rau kev ua kom cov diameters loj los ntawm nqaim sawb ntawm cov hlau. Tus Spiral duab kuj tseem tuaj yeem pab faib kev ntxhov siab sib txawv.

### 2. Dab tsi yog qhov txawv ntawm Erd thiab LSAWW PIPES?
Thawj qhov sib txawv yog kev tsim khoom lag luam thiab qhov tshwm sim loj thiab lub zog ntawm cov kav dej.
** ERW (hluav taws xob tiv thaiv welded) Yeeb: ** Cov yeeb nkab yog tsim los ntawm cov hlau nplaum uas txias, thiab nws txoj phuam yog welded yam tsis muaj kev siv cov khoom siv cev qhuav. Lub vuam vuam yog ua tiav los ntawm kev thov hluav taws xob tam sim no rau cov npoo, uas ua kom lawv mus txog thaum lawv fuse ua ke hauv siab.
** LSAW (Longitudinal submerged arc welded) yeeb nkab: ** Cov yeeb nkab no yog tsim los ntawm cov hlau nplaum steel (skelp). Lub phaj yog khoov thiab tsim rau hauv lub tog raj kheej, feem ntau siv ib tug u - e (uing, thiab nthuav dav). Nws ntev, ncaj seeam yog tom qab ntawd welded sab hauv thiab sab nraud siv cov submerged arc vuam (uas siv cov hlau glux thiab kev txuas ntxiv hlau electrode.
Lub ntsiab cuam tshuam yog:
* ** ERW ** yog feem ntau siv rau qhov tsawg rau nruab nrab cov ntawv thov zoo li cov khoom xa dej, fencing, thiab scaffolding. Nws muaj nyob rau hauv me me diameters.
* ** LSAW ** yog muaj zog dua, siv rau qhov loj dua qub thiab cov ntawv thov tseem ceeb, cov ntaub ntawv tseem ceeb, thiab roj teeb. Lub submerged arc weld yog thicker thiab muaj kev ntseeg siab dua.

### 3. Dab tsi yog qhov txawv ntawm ERW thiab HFW YEEB?
Tsis muaj cov kev sib txawv ntawm qhov sib txawv. ** HFW (High zaus welded) yeeb nkab yog hom ntawv ntawm ERW. **
** ERW (hluav taws xob tiv thaiv welded) yeeb nkab: ** Nov yog qeb dav dav rau cov kav dav hlau siv hluav taws xob siv hluav taws xob. Keeb kwm, nws siv qis - zaus.
** HFW (High zaus Welded) Yeeb: ** Qhov no yog cov qauv niaj hnub no rau ERW kav. Nws siv lub siab - cov hluav taws xob hluav taws xob tam sim no (ntau dua 70,000 HZ) kom mloog cov cua sov heev ntawm cov npoo ntawm cov sawb raug welded. Qhov no ua rau muaj kev kub siab ntau dua weld nrog ib qho kub me dua {{5 5}} cov impurities piv rau cov laus tsawg {zaus erw txoj kev.
Hauv kev xyaum hnub no, thaum tib neeg xa mus rau ** ERW ** YEEB NKAUJ, lawv yuav luag txhais tau tias txhais tau ** HFW ** yeeb nkab. HFW yog cov thev naus laus zis, cov thev naus laus zis rau cov hluav taws xob ua haujlwm vuam.

### 4. Dab tsi yog qhov sib txawv ntawm LSAW thiab hsaw kav?
Qhov sib txawv yog qhov qhia ntawm Weld Seam.
** LSAW tawm (Longitudinal submerged arc welded) Yeeb): ** Cov yeeb nkab no muaj ib leeg ncaj weld seam uas khiav mus sib dhos rau cov yeeb nkab lub axis. Nws yog tsim los ntawm ib lub phaj steel uas tsim thiab tom qab ntawd welded raws nws qhov ntev.
** hsaw (helical submerged arc welded) yeeb nkab: ** Qhov no yog lub npe ntawm ** kauv yeeb nkab **. Nws muaj kev txuas ntxiv weld seam uas koj kauv ib ncig ntawm cov yeeb nkab lub cev. Nws yog tsim los ntawm Helically Whing hlau coil thiab vuam cov leeg siv cov submermed arc txheej txheem.
Lub ntsiab cuam tshuam yog:
* ** LSAWW ** yog paub rau nws txoj kev raug thiab qhov raug thiab kev kub siab tiv taus. Nws yog qhov kev xaiv uas nyiam tshaj plaws rau feem ntau tus ntoo khaub lig- Lub teb chaws roj thiab roj pipelines.
* ** HSAWW / KAUV STABL ** yog qhov zoo heev rau kev tsim cov diameters loj heev. Txawm li cas los xij, lub sijhawm ntev, Kauv Weld tuaj yeem yog qhov muaj peev xwm ua rau muaj kev ntxhov siab hauv qee qhov kev ntxhov siab los ua kom ncaj.

### 5. Dab tsi yog qhov sib txawv ntawm DSAW thiab LSAWW PIPES?
** DSAW (ob npaug submerged arc welded) yeeb nkab ** yog hom tshwj xeeb ntawm ** lsaw ** Yeeb.
** LSAW tawm (Longitudinal submerged arc welded) Yeeb): ** Lo lus no muaj nws txoj kev ntev (ncaj) khi siv cov submerged ARC cov txheej txheem. Nws tuaj yeem hais txog cov kav dej nrog ib leeg.
** DSAW (Ob Chav Submered Arc Welded) Yeeb) Txhais tau hais tias lub sijhawm ntev heev txhais tau tias qhov kev sib tw ntev ntawm ob qho ** sab nraud ** siv cov txheej txheem arc. Qhov no ob chav vuam tsim ib lub zog heev thiab txhim khu kev qha weld sib koom ua ke, uas yog qhov tseem ceeb rau kev siv ntxhov siab.
Hauv cov ntsiab lus, txhua daim kav dej dwsaw yog lsaw kav, tab sis tsis yog txhua lsaw kav yog hais kom meej meej hu ua dsaw. Txawm li cas los xij, hauv kev coj ua niaj hnub no rau loj {1} rsw kab kab uas yuav luag ua rau ob sab, ua cov lus cog tseg feem ntau siv sib hloov pauv. "DSAW" yog siv los hais txog kev ua tau zoo dua ntawm ob {{3} {sided weld.
