Dab tsi yog qhov txawv ntawm stainless erw raj thiab seamless stainless hlau yeeb nkab?
Raws li lub npe qhia, cov kav dej uas tsim tsis tau siv lub vuam seam yog hu ua seamless kav. Txawm li cas los xij, cov kav dej welded muaj lub xub ntiag ntawm qhov ntev weld seam ntawm lawv qhov chaw. Ntxiv rau txoj kev tsim kho, lub siab muaj peev xwm, tus nqi, thiab kev siv ntawm txhua hom yeeb nkab sib txawv ntawm lwm qhov.
Tus nqi sib txawv ntawm stainless seamless thiab erw ss kav
Txij li cov kav dej seamless muaj cov txheej txheem tsim khoom ntev dua, thiab kev ua haujlwm ntawm no muaj ntau yam, tus nqi ntawm cov kav dej seamless yog ib txwm siab dua piv rau cov yeeb nkab welded. ERW cov kav dej siv cov ntawv txias tsim, uas tom qab ntawd sib koom ua ke los ntawm kev siv vuam ntau zaus, uas yog cov txheej txheem yooj yim, nrog rau cov nqi sib piv nrog rau ntau yam seamless.
Vim li cas siv stainless seamless yeeb nkab es tsis txhob erw ss kav?
Muaj ob qhov txiaj ntsig ntawm kev siv cov yeeb nkab seamless. Ua ntej, lub peev xwm ua haujlwm ntawm cov yeeb nkab seamless yog 20% siab dua cov yeeb nkab erw, vim hais tias, tsis zoo li cov kav dej erw, daim ntawv thov ntawm qib siab dua yuav tsis ua rau cov yeeb nkab tawg lossis tawg. Thiab lwm qhov, qhov laj thawj nrov dua rau kev xaiv cov yeeb nkab seamless yog tias lawv tsis muaj kev cuam tshuam rau intergranular corrosion. Raws li qhov tsis zoo ntawm cov kav dej seamless, cov kab seam ntawm cov kav dej welded, tshwj xeeb tshaj yog, HAZ lossis tshav kub cuam tshuam weld cheeb tsam tau txais kev cuam tshuam ntawm cov ciam teb vim muaj kev kub ntxhov. Qhov no txhawb nqa intergranular corrosion, yog li ua rau cov yeeb nkab tsis muaj zog.
