Kev Ntsuas Hydrostatic
Peb siv ntau yam kev sim uas tsis muaj kev puas tsuaj thiab kev sim siab hydrostatic los xyuas kom meej lub zog thiab kav ntev ntawm txhua cov yeeb nkab.Peb muab peb cov neeg siv khoom nrog cov khoom siv steel yeeb nkab uas ua tau raws li cov qauv siab tshaj plaws ntawm kev nyab xeeb thiab kev ruaj ntseg zoo.
Hollow seem raj tsim raws li EN 10219 yog weldable.
Thaum welding, txias cracking nyob rau hauv weld cheeb tsam yog lub ntsiab kev pheej hmoo raws li lub thickness, lub zog theem, thiab CEV ntawm cov khoom nce.Kev sib tsoo txias yog tshwm sim los ntawm kev sib xyaw ua ke ntawm ntau yam:
qib siab ntawm diffusible hydrogen nyob rau hauv weld hlau;
ib tug nkig qauv nyob rau hauv lub tshav kub-cuam tshuam cheeb tsam;
tseem ceeb tensile kev nyuaj siab concentration nyob rau hauv lub welded sib koom.
EN 10219 steel kav yog tsim rau kub dip galvanizing.Kev xaiv tuaj yeem ua raws li qhov xav tau tiag tiag.
Yuav tsum muaj lub ntsej muag du sib haum rau txoj kev tsim khoom siv;pob, voids, los yog ntiav longitudinal grooves uas tshwm sim los ntawm cov txheej txheem raug tso cai yog hais tias lawv residual thickness nyob rau hauv kam rau ua.
Cov kev puas tsuaj saum npoo tuaj yeem raug tshem tawm los ntawm kev sib tsoo, yog tias lub thickness ntawm cov kho hollow seem tsis tsawg tshaj li qhov tsawg kawg nkaus tso cai thickness teev nyob rau hauv EN 10219-2.
