Txheej txheem cej luam ntawm erw/hfw kav
ERW yeeb nkab yog lub ntsiab lus rau hluav taws xob tiv thaiv welded steel yeeb nkab, thiab HFW yeeb nkab sawv cev rau high-frequency welding (HFW) steel yeeb nkab & raj. Cov kav dej yog tsim los ntawm steel coil thiab weld seam khiav parallel mus rau cov yeeb nkab. Thiab nws yog ib qho ntawm ntau yam cuab yeej siv hauv kev ua liaj ua teb, kev lag luam, thiab kev tsim kho. Cov txheej txheem tsim khoom ntawm ERW steel yeeb nkab suav nrog HFW. ERW cuam tshuam nrog qis, nruab nrab, thiab siab zaus vuam, thaum HFW tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob ntau zaus vuam yeeb nkab.
Nta ntawm erw / hfw kav
1. Piv nrog rau lwm hom ntawm welded kav, ERW kav dej muaj zog ntau dua.
2. Kev ua tau zoo dua li cov kav dej welded thiab tus nqi qis dua cov kav dej seamless.
3. Cov txheej txheem ntau lawm ntawm ERW kav dej muaj kev nyab xeeb dua li lwm cov welded kav.
