Tsim los ntawm kev sib txuas txuas ntxiv ntawm cov hlau kauj nrog ob -sided submerged arc vuam, nws muab kev ua haujlwm sib luag hauv lub peev xwm siab, kev ruaj khov, kev ua haujlwm zoo, thiab kev tsim kho yooj yim. Phau ntawv qhia no suav nrog kev lag luam-cov kev qhia tshwj xeeb uas siv tau, cov qauv siv thoob ntiaj teb, kev tiv thaiv corrosion, cov kev xav tau zoo, thiab qhov project- cov txheej txheem xaiv tshwj xeeb los txhawb kev tsim engineering thiab kev txiav txim siab tsim.
SSAW Yeeb Nkab rau Kev xa dej yog dab tsi?
SSAW yeeb nkab, tseem hu ua kauv welded yeeb nkab, yog tsim los ntawm dov kub - dov steel kauj mus rau hauv ib tug helical tubular zoo, ces welding lub kauv seam los ntawm ob sab hauv thiab sab nraud ntawm lub submerged arc vuam (SAW) txheej txheem.
Tsis zoo li ncaj seam welded yeeb nkab, kauv weld seam tsim ib lub kaum oblique nrog cov yeeb nkab axis, uas pab faib hoop thiab axial stresses ntau uniformly, txo cov kev ntxhov siab hauv zos. Cov yam ntxwv ntawm cov qauv no ua rau nws tshwj xeeb tshaj yog haum rau loj - txoj kab uas hla cov kav dej uas ua haujlwm nyob rau hauv lub sij hawm ntev - lub sij hawm siab thiab ntsia nyob rau hauv complex struts thiab txawv av tej yam kev mob.
