Cov khoom siv qib dab tsi yog ASTM A53 Class B tsis kam-welded structural yeeb nkab rau?
ASTM A53 Class B tsis kam -welded structural yeeb nkabbelongs rau ASTM A53 Class B khoom tus qauv. Cov qauv no qhia txog hom carbon steel yeeb nkab uas ua tau raws li qhov yuav tsum tau ua rau kev tsim cov txheej txheem xws li kev siv vuam, seamless welding, thiab rauv taub qab vuam.
Cov txheej txheem vuam dab tsi feem ntau yog siv rau ASTM A53 Class B tsis kam-welded structural yeeb nkab?
ASTM A53 Class B tsis kam -welded yeeb nkabFeem ntau yog tsim los siv cov txheej txheem welding (ERW). Nyob rau hauv cov txheej txheem no, cov nplooj ntawv steel yog dov rau hauv lub tog raj kheej, thiab tom qab ntawd cov cua sov tsim los ntawm cov hlau tsis kam yog siv los vuam cov seams ua ke. Cov txheej txheem no tsim cov kav dej los ntawm kev tsim cov hlau txuas txuas ntxiv.
Dab tsi yog qhov txawv ntawm ASTM A53 Class B tsis kam-welded structural yeeb nkab thiab kauv welded yeeb nkab?
Qhov sib txawv tseem ceeb nyob hauv cov txheej txheem tsim khoom. Weld seam ntawmASTM A53 Class B tsis kam -welded yeeb nkabyog ncaj; thaum kauv welded yeeb nkab yog tsim los ntawm kev txuas txuas txuas txuas welding steel coils. Qhov no ua rau muaj qhov sib txawv weld seam kev taw qhia.ASTM A53 Class B tsis kam -welded yeeb nkabyuav tsum tau tom qab-weld heat treatment, hos kauv vuam yog lwm txoj kev nruam.
Dab tsi yog cov qauv siv rau ASTM A53 Class B kuj welded structural raj?
ASTM A53 Class B tsis kam welded rajyog tsim rau kev siv cov qauv siv dav dav, xws li kev txhawb nqa hauv tsev, scaffolding, thiab cov khoom siv tshuab, nrog rau cov dej nruab nrab mus rau qis qis, chav dej, thiab huab cua thauj.
Cov cuab yeej cuab tam twg yuav tsum tau xeem rau ASTM A53 Class B tsis kam welded cov qauv raj?
RauASTM A53 Class B tsis kam welded (ERW) cov hlab ntsha, cov kev xeem uas yuav tsum tau muaj xws li kev sim hydrostatic, kev sim flattening, kuaj lub zog tensile, yield zog kuaj, thiab kuaj elongation.
