Longitudinal submerged arc welded yeeb nkab (LSAW) feem ntau yog ua los ntawm steel phaj ua raw khoom. Tom qab sib txawv txheej txheem, ob-sided submerged arc vuam thiab post-weld txoj kab uas hla expansion yog saws los ua welded yeeb nkab.
Cov cuab yeej tseem ceeb suav nrog lub tshuab milling, lub tshuab ua ntej dabtsi yog khoov, lub tshuab ua ntej, lub tshuab ua ntej vuam, lub tshuab nthuav dav, thiab lwm yam. Tib lub sijhawm, muaj ntau hom kev sib sau rau LSAW kav: UO (UOE), RB (RBE) , JCO (JCOE), thiab lwm yam. Cov phaj hlau yog thawj zaug nias rau hauv U zoo nyob rau hauv txoj kev tuag, thiab ces nias rau hauv O zoo, thiab ces sab hauv thiab sab nraud submerged arc vuam yog nqa tawm. Tom qab vuam, nws feem ntau hu ua UOE welded yeeb nkab thaum kawg lossis tag nrho ntev. Nws yog UO welded yeeb nkab. Yob dabtsi yog khoov cov hlau phaj, thiab tom qab ntawd ua sab hauv thiab sab nraud submerged arc vuam. Tom qab vuam, txoj kab uas hla yog nthuav mus rau RBE welded yeeb nkab lossis tsis yog RB welded yeeb nkab. Cov hlau phaj yog tsim nyob rau hauv kev txiav txim ntawm J hom-C hom-O hom, thiab txoj kab uas hla yog nthuav mus rau JCOE welded yeeb nkab los yog tsis mus rau JCO welded yeeb nkab tom qab vuam.
UOE longitudinal submerged arc welded yeeb nkab txoj kev
Peb lub ntsiab txheej txheem ntawm UOE LSAW steel yeeb nkab txoj kev muaj xws li: steel phaj pre-bending, U forming thiab O forming. Txhua tus txheej txheem siv lub siab sib sau xovxwm los ua kom tiav peb cov txheej txheem ntawm kev khoov ua ntej, U-forming thiab O-forming ntawm steel phaj ntug nyob rau hauv ib theem zuj zus kom deform lub steel phaj rau hauv ib puag ncig raj.
