ERW vuam txheej txheem yog dab tsi?
ERW, los yogtsis kam vuam, yog txheej txheem vuam uas siv siab - zaus tam sim no los ua kom sov cov hlau qhov chaw thiab siv lub siab rau qhov sib koom ua ke, yog li txuas mus tas li cov khoom siv hlau. Qhov tam sim no generates tshav kub los ntawm qhov tsis kam ntawm cov hlau, melting cov khoom ntawm qhov chaw sib cuag thiab tsim ib tug muaj zog weld.
Cov qauv zoo li cas S355J2H ERW dub welded yeeb nkab ua tau raws li?
S355J2H ERW dub welded yeeb nkabFeem ntau ua raws li EN 10210 thiab EN 10219 cov qauv, uas yog cov qauv European rau cov qauv hollow profiles. Cov qauv no qhia meej tias nws tsis yog- alloy zoo- steel hlau.
Vim li cas qhov nto ntawm S355J2H ERW dub welded yeeb nkab dub?
Qhov saum npoo ntawmS355J2H ERW dub welded yeeb nkabyog xim dub vim hais tias ib txheej ntawm cov hlau oxide dub tsim thaum lub sij hawm siab - txheej txheem tsim khoom kub. Cov nplai oxide no yog cov khoom siv los ntawm cov cua kub cua sov thiab tsis yog txheej tiv thaiv nws tus kheej, tab sis nws muab qee qhov kev tiv thaiv corrosion piv rau qhov huv si.
Dab tsi yog qhov zoo ntawm S355J2H ERW dub welded yeeb nkab?
Lub ntsiab zoo ntawmS355J2H ERW dub welded yeeb nkabyog nws lub zog siab thiab zoo toughness, cia nws tiv taus hnyav loads thiab cuam tshuam txawm nyob rau hauv ib puag ncig txias. Nws kuj boasts zoo heev weldability, yooj yim ntawm kev ua, thiab zoo corrosion kuj.
Dab tsi engineering tej yaam num yog S355J2H ERW dub welded kav mas siv nyob rau hauv?
S355J2H ERW dub welded kavyog dav siv nyob rau hauv ntau yam engineering tej yaam num, xws li steel lug (bridges, high{0}}nce tsev), infrastructure (subways, tunnels), lub zog kev lag luam (cua zog yees, roj pipelines), thiab machinery manufacturing (hnyav- lub luag hauj lwm ncej, crane booms).
