Qhov txawv ntawm LSAW thiab SSAW Steel Pipes yog dab tsi?

Hauv lub ntiaj teb loj thiab nyuaj ntawm kev tsim cov yeeb nkab steel, ob hom welded kav feem ntau tuaj rau hauv kev txiav txim siab rau cov haujlwm loj -: Longitudinally Submerged Arc Welded (LSAW) kav thiab Kauv Submerged Arc Welded (SSAW) kav. Ob leeg yog tsim los siv cov txheej txheem Submerged Arc Vuam (SAW), paub txog nws cov qib siab - zoo welds. Txawm li cas los xij, lawv txoj kev tsim khoom sib txawv ua rau muaj qhov sib txawv loj hauv lawv cov khoom, kev siv, thiab tus nqi -kev ua tau zoo. Kev nkag siab txog cov kev sib txawv no yog qhov tseem ceeb rau cov engineers thiab cov thawj tswj xyuas qhov project los xaiv cov yeeb nkab zoo rau lawv cov kev xav tau tshwj xeeb. Yog li, qhov txawv ntawm LSAW thiab SSAW steel kav yog dab tsi? Hebei Huayang Steel Pipe Co., Ltd., yog ib lub chaw tsim khoom ntawm LSAW thiab SSAW kav, muab cov ncauj lus kom ntxaws sib piv.

Nkag siab txog LSAW Steel Pipes

LSAW steel yeeb nkab yog tus yam ntxwv los ntawm ib qho, ncaj nraim longitudinal weld seam uas khiav parallel mus rau cov yeeb nkab axis. Lawv feem ntau yog tsim los ntawm ib lub phaj hlau, uas yog thawj zaug tsim rau hauv cov duab cylindrical (feem ntau siv cov txheej txheem JCOE: J-ing, C-ing, O-ing, Expanding) thiab tom qab ntawd welded sab hauv thiab sab nraud siv cov txheej txheem SAW. Tom qab welding, cov yeeb nkab feem ntau ua rau cov neeg kho tshuab nthuav dav kom ua tiav qhov ntev thiab txo cov kev ntxhov siab sab hauv.

Cov yam ntxwv tseem ceeb ntawm LSAW Pipes:

•Seam: Ib qho ncaj longitudinal weld seam.

• Raw Khoom: Ib leeg hlau phaj.

•Diameter Range: Feem ntau loj dua diameters, feem ntau ntawm 406mm (16 ntiv tes) mus txog 1422mm (56 ntiv tes) lossis loj dua.

• Phab ntsa Thickness: Muaj peev xwm tsim cov phab ntsa hnyav heev, feem ntau tshaj 80mm.

• Daim ntawv thov: nyiam rau siab - siab, siab - lub zog, thiab cov ntawv thov tseem ceeb xws li ntev - cov kav dej thiab cov roj xa mus, cov kav dej tawm ntug dej, cov txheej txheem piling, thiab tob - cov dej num.

Nkag siab txog SSAW Steel Pipes

SSAW steel kav, tseem hu ua Helical Submerged Arc Welded kav los yog HSAW kav, muaj ib tug kauv weld seam uas khiav helically raws li ntev ntawm cov yeeb nkab. Lawv yog tsim los ntawm spirally forming steel coil (strip) rau hauv cov yeeb nkab zoo thiab ces welding ob sab hauv thiab sab nraud ntawm kauv seam siv cov txheej txheem SAW. Lub kaum sab xis tuaj yeem hloov kho kom tsim tau ntau yam yeeb nkab diameters los ntawm ib qhov dav ntawm steel kauj.

Cov yam ntxwv tseem ceeb ntawm SSAW Pipes:

•Seam: Ib qho txuas txuas txuas txuas txuas txuas.

•Raw Khoom: Hlau coil (strip).

•Diameter Range: Muaj peev xwm tsim tau ntau txoj kab uas hla los ntawm qhov nqaim steel coil, feem ntau ntawm 219mm (8 ntiv tes) mus txog 3048mm (120 ntiv tes) lossis ntau dua.

• Phab ntsa Thickness: Feem ntau txwv rau nruab nrab phab ntsa tuab piv rau LSAW, txawm tias cov phab ntsa hnyav tuaj yeem ua tau.

• Daim ntawv thov: Siv dav rau kev xa dej, kev tso dej, kev siv cov qauv, kev sib txuas, thiab cov kav dej tsis tshua muaj roj thiab roj.

Qhov Tseem Ceeb Qhov Sib Txawv: Kev Sib Piv Kev Ntsuas

Thaum ob leeg LSAW thiab SSAW kav siv SAW vuam txheej txheem, lawv txoj kev tsim khoom ua rau muaj qhov sib txawv uas cuam tshuam rau lawv qhov tsim nyog rau ntau yam haujlwm.

1. Cov txheej txheem tsim khoom thiab cov khoom siv raw

•LSAW: Pib nrog ib lub phaj steel loj. Lub phaj yog tsim thiab ces welded longitudinally. Cov txheej txheem no yog qhov nyuaj dua thiab xav tau cov khoom siv loj dua, tshwj xeeb dua.

•SSAW: Pib nrog steel kauj (strip) uas yog spirally tsim thiab welded. Qhov no tso cai rau kev tsim khoom tas mus li thiab ua kom yooj yim dua nyob rau hauv txoj kab uas hla los ntawm ib lub coil dav.

2. Weld Seam Orientation thiab Ntev

• LSAW: Nws muaj ib leeg, ncaj longitudinal weld seam. Qhov ntev ntawm lub vuam seam yog sib npaug rau qhov ntev ntawm cov yeeb nkab.

• SSAW: Nws muaj ib tug kauv weld seam. Qhov ntev ntawm lub vuam seam yog qhov ntev dua li cov yeeb nkab ntev, vim nws spirals nyob ib ncig ntawm cov yeeb nkab.

3. Txoj kab uas hla thiab phab ntsa Thickness muaj peev xwm

•LSAW: Excels hauv kev tsim cov diameters loj heev nrog cov phab ntsa hnyav, ua rau nws zoo tagnrho rau kev siv siab -siab.

• SSAW: Muaj ntau txoj kab uas hla, feem ntau loj dua LSAW, tab sis feem ntau pheej yig dua rau nruab nrab phab ntsa thicknesses. Txawm hais tias muaj cov kab loj loj tuaj yeem ua tau, cov phab ntsa hnyav hnyav tuaj yeem nyuaj lossis raug nqi tsawg dua - siv tau.

4. Internal Stress Distribution

• LSAW: Lub longitudinal weld seam yog perpendicular rau cov yeeb nkab lub ntsiab kev nyuaj siab (hoop stress) nyob rau hauv lub siab. Cov txheej txheem nthuav dav siv tshuab pab daws cov kev ntxhov siab sab hauv.

• SSAW: Lub kauv vuam seam yog faib raws cov yeeb nkab, thiab nws txoj kev ntxhov siab tsis yog perpendicular rau qhov kev ntxhov siab loj. Tej zaum qhov no tuaj yeem ua rau muaj kev sib txawv ntawm kev ntxhov siab.

5. Tus nqi -Kev ua tau zoo

•LSAW: Feem ntau cov nqi tsim khoom ntau dua vim yog siv cov hlau loj loj thiab cov txheej txheem tsim ntau dua. Txawm li cas los xij, nws qhov kev ua tau zoo tshaj plaws qhia txog tus nqi rau cov ntawv thov tseem ceeb.

•SSAW: Feem ntau tus nqi ntau dua - siv tau rau ib txoj kab uas hla, tshwj xeeb tshaj yog rau cov phab ntsa nruab nrab, vim yog cov khoom siv txuas ntxiv los ntawm cov coils thiab cov cuab yeej tsim tsis tshua muaj.

6. Kev Tswj Xyuas Zoo thiab Kev Tshawb Fawb

• Ob hom yeeb nkab tau dhau NDT nruj. Txawm li cas los xij, txoj hlua ncaj nraim ntawm LSAW kav qee zaum tuaj yeem ua kom yooj yim rau qee cov txheej txheem NDT piv rau cov kauv vuam ntawm SSAW kav.

Kev Xaiv Ntawm LSAW thiab SSAW: Daim Ntawv Thov -Txoj Kev Txiav Txim Siab

Kev xaiv ntawm LSAW thiab SSAW kav feem ntau yog nyob ntawm cov kev cai tshwj xeeb ntawm qhov project:

• Xaiv LSAW thaum:

• Kev kub siab sab hauv thiab cov khoom thauj sab nraud tau xav txog (piv txwv li, siab - cov kav dej siab / cov pa roj, qhov tob - cov kav dej tawm ntug dej hiav txwv).

• Heavy phab ntsa thickness thiab txoj kab uas hla loj yuav tsum tau.

• Qhov siab tshaj ntawm cov qauv kev ntseeg siab thiab kev ntseeg siab yog qhov tseem ceeb.

•Qhov project xav tau qhov zoo tshaj plaws thiab nruj tshaj plaws specifications (piv txwv li, API 5L PSL2).

• Xaiv SSAW thaum:

• Cov kab loj loj yog xav tau, tab sis cov kev xav tau siab yog nruab nrab (piv txwv li, kev xa dej, kev tso dej).

• Nqi-kev ua tau zoo yog qhov kev txhawj xeeb tseem ceeb rau nruab nrab- cov ntawv thov siab.

•Flexibility nyob rau hauv txoj kab uas hla ntau lawm los ntawm ib co coil dav yog qhov zoo.

•Structural applications thiab piling qhov twg cov kauv weld tau txais.
