LSAW Welded Steel Yeeb Nkab
Longitudinal submerged arc welded steel kav yog tsim los ntawm ob-sided tsis siv neeg submerged arc vuam los yog ib sab welding. Lawv yog siv rau kev thauj mus los ntawm cov dej uas tsis tshua muaj siab xws li dej, roj, cua, thiab chav.
Cov yam ntxwv ntawm submerged arc vuam txheej txheem yog cov nyhuv electrothermal ntawm vuam hlau thiab kub melting ntawm cov muab tub lim vuam steel phaj. Submerged arc welded ncaj seam steel kav muaj cov khoom siv sib cuam tshuam nrog txog 15 txheej txheem. High-frequency ncaj seam steel kav muaj ob peb cov specifications thiab nyias ntau lawm thickness. Submerged arc welded ncaj seam steel kav yuav ua tau nyob rau hauv tej yam specifications ntawm 325 mus rau ntau tshaj 1600 hli, thiab lub thickness yog nyob rau hauv 80 hli.
Cov yam ntxwv ntawm LSAW Welded Steel raj
Kev ua haujlwm siab: Kev tsim khoom ceev ntawm longitudinal submerged arc welded steel kav yog ceev ceev, uas zoo heev txhim kho efficiency.
Cov khoom lag luam zoo: Cov vuam zoo ntawm cov seam ncaj nraim submerged arc welded steel kav yog ruaj khov thiab txhim khu kev qha, thiab muaj kev tiv thaiv corrosion zoo.
Kev siv ncaj seam submerged arc welded steel kav
1. Roj thiab roj kis tau tus mob pipelines: Submerged arc ncaj seam welded steel kav yog dav siv nyob rau hauv kev sib kis pipelines nyob rau hauv cov roj thiab natural gas kev lag luam thiab muaj cov yam ntxwv ntawm muaj zog siab bearing muaj peev xwm thiab zoo anti-corrosion muaj peev xwm.
2. Cov kav dej rau kev tsim vaj tsev: Raws li tus neeg nqa khoom ntawm cov qauv tsim, cov kav ntev submerged arc welded steel kav ua lub luag haujlwm tseem ceeb xws li ntaiv, txuas hniav, thiab lub tsev thav duab.
3. Cov kav dej txhawb nqa hydraulic: LSAW Welded Yeeb Nkab yog siv los ua cov kav dej txhawb nqa hydraulic hauv kev lag luam xws li cov roj qhov dej thiab cov mines thee thiab muaj lub siab tsis kam thiab corrosion kuj.
