LSAW Yeeb Nkab(Longitudinal Submerged Arc-Welding Pipe), tseem hu uaSAWL yeeb nkabNws yog siv cov hlau phaj ua cov khoom siv raw, pwm nws los ntawm lub tshuab molding, tom qab ntawd ua ob sab submerged arc vuam. Los ntawm cov txheej txheem no LSAW steel yeeb nkab yuav tau txais kev ua haujlwm zoo heev, weld toughness, uniformity, plasticity thiab sealing zoo.
Lub raj LSAW txoj kab uas hla ntau dua li ERW, feem ntau yog txij li 406mm txog 2020mm. Kev ua tau zoo ntawm kev tiv taus siab, thiab kev tiv taus xeb kub tsawg.
SSAW Yeeb Nkab(Kauv Yeeb Nkab Uas Muab Kauv Rau Hauv Qab Av), tseem hu uaHSAW yeeb nkab(Helical SAW), cov kab vuam zoo li lub helix. Nws siv tib lub tshuab vuam ntawm Submerged Arc-Welding nrog LSAW yeeb nkab. Txawv SSAW yeeb nkab yog spiral welded qhov twg LSAW yog longitudinally welded. Cov txheej txheem tsim khoom yog dov cov hlau strip, kom ua rau qhov kev taw qhia dov muaj lub kaum sab xis nrog qhov kev taw qhia ntawm lub yeeb nkab nruab nrab, tsim thiab vuam, yog li cov seam vuam yog nyob rau hauv ib txoj kab spiral.
Lub raj xa dej SSAW muaj qhov loj li ntawm 219 hli txog 2020 hli. Qhov zoo dua yog peb tuaj yeem tau txais cov raj xa dej SSAW sib txawv nrog tib qhov loj ntawm cov hlau, muaj ntau daim ntawv thov rau cov khoom siv hlau raw, thiab vuam seam yuav tsum zam kev ntxhov siab thawj zaug, kev ua tau zoo los dais kev ntxhov siab.
