LSAW (Longitudinal ob chav submerge arc vuam)cov yeeb nkab hlauyog ib homSAW yeeb nkabua los ntawm cov phaj hlau uas tau kub dov los ntawm JCOE lossis UOE txoj kev tsim khoom. JCOE thev naus laus zis sawv cev rau cov txheej txheem puab thiab tsim khoom uas koom nrog thaum lub sijhawm tsim khoom nrog rau kev vuam sab hauv thiab sab nraud thiab kev nthuav dav txias ua tom qab vuam.
Thaum piv rau UOECov kav hlau LSAW, Cov chaw tsim khoom yeeb nkab LSAW hauv Suav teb tuaj yeem tsim ntau qhov ntau thiab tsawg raws li no: OD 406 hli - 1620 hli, tuab 6.35 hli - 60 hli, yeeb nkab ntev 2 m - 18 m nrog rauLSAW yeeb nkabmuaj kev zoo dua.
- Cov txheej txheem tsim cov yeeb nkab LSAW steel
LSAWcov yeeb nkab loj uas muaj txoj kab uas hlaCov txheej txheem tsim khoom tau piav qhia hauv cov kauj ruam hauv qab no:
1. Phaj Soj Ntsuam: Qhov no yog siv rau kev tsim cov pob qij txha LSAW loj tom qab nws nkag mus rau hauv kab ntau lawm uas yog thawj qhov kev kuaj ultrasonic puv ntoob.
2. Kev Sib Tsoo: Lub tshuab siv rau kev sib tsoo ua qhov kev ua haujlwm no los ntawm ob-ntug sib tsoo phaj kom ua tau raws li qhov yuav tsum tau ua ntawm qhov dav ntawm phaj thiab sab sib luag rau cov duab thiab degree.
3. Sab uas nkhaus ua ntej: Sab no ua tiav los ntawm kev siv lub tshuab khoov ua ntej ntawm ntug phaj uas khoov ua ntej. Ntug phaj yuav tsum ua tau raws li qhov yuav tsum tau khoov.
4. Kev Tsim: Tom qab cov kauj ruam ua ntej khoov, hauv thawj ib nrab ntawm lub tshuab JCO molding, tom qab stamped hlau, nws raug nias rau hauv daim duab "J" thaum ntawm ib nrab ntawm tib lub phaj hlau nws raug khoov thiab nias rau hauv daim duab "C", tom qab ntawd qhov qhib kawg tsim cov duab "O".
5. Kev vuam ua ntej: Qhov no yog ua kom cov yeeb nkab hlau vuam ua ib txoj kab ncaj tom qab nws tau tsim thiab tom qab ntawd siv cov roj vuam seam (MAG) rau kev vuam tas mus li.
6. Kev vuam sab hauv: Qhov no ua tiav nrog kev vuam tandem ntau txoj hlua submerged arc (kwv yees li plaub txoj hlua) rau sab hauv ntawm cov yeeb nkab hlau ncaj.
7. Kev vuam sab nraud: Kev vuam sab nraud yog kev vuam tandem ntau-hlau submerged arc rau sab nraud ntawm LSAW steel yeeb nkab vuam.
8. Kev Ntsuas Ultrasonic: Sab nraud thiab sab hauv ntawm cov yeeb nkab hlau ncaj nraim thiab ob sab ntawm cov khoom siv hauv paus yog welded nrog 100% kev tshuaj xyuas.
9. Kev tshuaj xyuas X-ray: Kev tshuaj xyuas TV hauv kev lag luam X-ray yog ua tiav rau sab hauv thiab sab nraud siv lub kaw lus ua duab kom paub tseeb tias muaj kev rhiab heev ntawm kev kuaj pom.
10. Kev nthuav dav: Qhov no yog rau kev ua tiav kev vuam submerged arc thiab txoj kab uas hla ntawm cov yeeb nkab hlau ncaj kom txhim kho qhov loj ntawm cov yeeb nkab hlau thiab txhim kho kev faib tawm ntawm kev ntxhov siab hauv cov yeeb nkab hlau.
11. Kev kuaj hydraulic: Qhov no yog ua tiav rau ntawm lub tshuab kuaj hydraulic rau hlau tom qab nthuav dav los ntawm kev kuaj xyuas kom ntseeg tau tias cov yeeb nkab hlau ua tau raws li tus qauv yuav tsum tau ua nrog lub tshuab muaj peev xwm sau thiab khaws cia tsis siv neeg.
12. Chamfering: Qhov no suav nrog kev tshuaj xyuas ua tiav rau ntawm cov yeeb nkab hlau thaum kawg ntawm tag nrho cov txheej txheem.
