FAQ
Qhov txawv ntawm cov yeeb nkab thiab LSAW yeeb nkab yog dab tsi?
Qhov txawv yogSSAW kav yog welded nyob rau hauv lub helix los yog kauv txoj hauj lwm thaum LSAW kav yog welded nyob rau hauv lub longitudinal kev taw qhia. Kev tsim cov txheej txheem ntawm SSAW yeeb nkab yog dov thiab vuam ib txoj hlua hlau nyob rau hauv ib txoj kev uas cov kev taw qhia pivotal yog oblique rau lub axis los yog yeeb nkab chaw, ua rau cov weld seam nyob rau hauv ib tug kauv kab.
Dab tsi yog qhov txawv ntawm HSAW thiab LSAW kav?
Ntxiv thiab,LSAW cov kav dej zoo li muaj qhov tseeb dua geometric, uas yog ib qho tseem ceeb ntawm kev yooj yim installation thiab kev ua tau zoo tag nrho. HSAW steel kav, nrog lawv cov kauv vuam seam, muaj cua sov loj dua - thaj tsam cuam tshuam piv rau LSAW kav.
