EN 10219 yog dab tsi?

TS EN 10219 Cov Txheej Txheem European no qhia txog cov txheej txheem kev xa khoom rau cov khoom txias tsim welded structural hollow seem ntawm ncig, square lossis duab plaub thiab siv rau cov qauv hollow seem tsim txias yam tsis muaj kev kho cua sov tom qab.

EN 10219 zoo ib yam rau BS EN 10219, tshwj tsis yog tias nws siv rau ntau lub tebchaws. Tag nrho cov kev cai hauv qab no kuj tseem siv tau rau BS EN 10219.

Kev Xa Khoom

Cov seem hollow yuav tsum xatxias tsim yam tsis muaj kev kho cua sov tom qabtshwj tsis yog tias cov weld seam yuav nyob rau hauv raws li welded los yog kub kho mob.

CEEB TOOM: Rau SAW hollow seem saum toj no 508 mm sab nraud txoj kab uas hla tej zaum yuav tsim nyog los ua ib tug sov so shaping lag luam, uas tsis cuam tshuam rau cov neeg kho tshuab zog, thiaj li ua tau raws li qhov tawm - ntawm - roundness kam rau ua.
