Introduction to LSAW Pipes
Longitudinal Submerged Arc Welded kav, feem ntau hu uaLSAW pipes, yog cov feem ntau siv welded steel kav nyob rau hauv loj - txoj kab uas hla engineering tej yaam num. Ua los ntawm kev ncaj nraim -seam vuam txoj kev, LSAW kav muaj qhov tshwj xeeb ntawm qhov tseeb, thauj khoom-cov kabmob muaj zog, thiab kev ntseeg tau. Cov kav dej no zoo tagnrho rau kev xav tau kev lag luam xws li kev xa roj thiab roj, kev tsim kho sab nrauv, kev sib txuas dej, thiab kev siv cov txheej txheem hnyav.
Raws li ib feem ntawm Huayang Steel Pipe cov khoom lag luam, LSAW kav txuas ntxiv ERW yeeb nkab thiab cov pa roj carbon steel yeeb nkab kev daws teeb meem los ntawm kev muab cov kab loj dua thiab cov phab ntsa tuab dua. Lawv tau txais txiaj ntsig tshwj xeeb thaum qhov kev xav tau tshaj qhov muaj peev xwm ntawm ERW vuam tshuab.
Nkag siab txog LSAW Pipe Manufacturing
LSAW kav yog tsim los ntawm cov hlau phaj uas tsim thiab welded raws ib tug longitudinal seam siv advanced submerged arc vuam. Cov txheej txheem txhim kho ob qho tib si weld kev ncaj ncees thiab kev ua haujlwm zoo.
Hlau phaj xaiv
Cov txheej txheem tsim khoom pib nrog kev xaiv qib siab - qib steel phaj, feem ntau los ntawm API, ASTM, lossis EN cov qauv. Cov phaj no feem ntau yog tsim los ntawm kev tswj cov dov los yog cov thermo-txheej txheem txheej txheem los xyuas kom meej cov khoom zoo ib yam.
Txoj kev tsim
LSAW kav yog tsim los ntawm ob txoj kev tsim:
UOE Txheej Txheem
Txoj kev UOE suav nrog:
- Nias lub phaj rau hauv ib qho U.
- Ntxiv shaping rau hauv daim ntawv O.
- Nthuav cov yeeb nkab kom ua tiav zoo meej roundness.
JCOE Txheej Txheem
Cov txheej txheem JCOE tsim cov hlau phaj incrementally:
- Nws yog nias thawj zaug rau hauv J hom.
- Tom qab ntawd mus rau hauv lub C shape.
- Thaum kawg rau hauv O zoo ua ntej nthuav dav.
Ob qhov txheej txheem tsim kom paub meej geometry thiab du sab hauv, zoo tagnrho rau kev thauj mus los ntawm cov dej.
Vuam thiab Mechanical Strength
Lub ntsiab feature ntawm LSAW yeeb nkab fabrication yogsubmerged arc vuam(SAW), ua ob qho tib si sab hauv thiab sab nraud kom xa cov kev nkag mus tau zoo, siab - zog vuam.
Muab ob npaug rau Vuam rau qhov siab tshaj plaws
LSAW pipes undergo:
- Internal SAW welding
- Sab nraud SAW welding
Qhov no dual -weld system ua rau lub siab zoo- cov kabmob muaj peev xwm, ua rau cov kav dej LSAW haum rau kev sib kis ntev - roj thiab roj.
Kev kho cua sov
Tom qab vuam, cov yeeb nkab yog cua sov- kho kom txo tau qhov kev ntxhov siab thiab xyuas kom meej cov khoom sib xws thoob plaws hauv lub cev thiab vuam seam.
Tsis yog -Kev kuaj kev puas tsuaj
Txhua lub raj xa mus:
- Kev kuaj ultrasonic
- Kev kuaj hluav taws xob
- Kev ntsuas hydrostatic siab
- Dimensional soj ntsuam
Cov no xyuas kom ua raws li API 5L, ASTM A671, A672, thiab lwm yam qauv thoob ntiaj teb.
Dimensional Range ntawmLSAW Pipes
LSAW kav feem ntau muab:
Muaj peev xwm loj
- Txoj kab uas hla: 406mm-1422mm
- Phab ntsa thickness: 6mm-50mm
- Ntev: mus txog 18 meters
Hom qauv
| Txuj | Kev piav qhia |
|---|---|
| API 5L | Kab yeeb nkab rau cov roj thiab cov kav dej |

Cov kev qhia tshwj xeeb no ua rau LSAW cov kav dej yog qhov kev xaiv zoo tshaj plaws rau lub zog, dej, thiab cov khoom siv.
Qhov zoo ntawmLSAW Pipes
LSAW cov kav dej muaj ntau qhov zoo piv nrog rau lwm cov yeeb nkab welded xws li ERW kav thiab SSAW kav.
1. Zoo heev Weld Quality
Ncaj- seam welding minimizes weld defects thiab xyuas kom meej txawm tias muaj kev ntxhov siab. Cov txheej txheem submerged arc vuam muab sib sib zog nqus weld nkag mus thiab zoo ib yam khoom siv.
2. Siab Dimensional raug
Cov txheej txheem tsim muab nruj tolerance nyob rau hauv txoj kab uas hla, phab ntsa thickness, thiab roundness.
3. Thick Wall Peev Xwm
LSAW cov kav dej tuaj yeem tsim nrog cov phab ntsa tuab dua li ERW cov kav dej, ua rau lawv haum rau kev siv siab - siab.
4. Tsawg Distortion
Kev tswj cov hluav taws xob hluav taws xob txo qis kev cuam tshuam, txhim kho cov qauv kev ntseeg tau.
5. Superior Performance nyob rau hauv hnyav ib puag ncig
Kev kho cua sov thiab kev ntsuas nruj ua rau cov kav dej LSAW muaj kev vam meej hauv:
