Dab tsi yog cov yam ntxwv tseem ceeb ntawm siab - zaus vuam?
Siab - zaus (HF) vuamsiv lub tshuab electromagnetic los tsim kom muaj cua sov ncaj qha rau hauv cov ntaub ntawv uas tau koom nrog, ces fuses lawv nyob rau hauv siab. Nws cov yam ntxwv tseem ceeb yog siab weld zog, seamlessness, thiab durability; siab vuam ceev; tsawg zog noj; ib qho cua sov me me- thaj tsam cuam tshuam, txo qhov deformation thiab discoloration; thiab feem ntau tsis muaj kev tshaj tawm -weld kho cua sov yuav tsum tau.
Nyob rau hauv tej yaam num engineering yog ASTM A53 Class B siab -frequency resistance welded (ERW) yeeb nkab feem ntau siv?
ASTM A53 Class B ERW yeeb nkabFeem ntau yog siv rau kev siv tshuab thiab kev siv siab, suav nrog kev thauj cov dej thiab roj hauv cov dej hauv nroog, cov kav dej thiab cov roj av, thiab kev tiv thaiv hluav taws. Nws kuj yog siv rau kev siv cov txheej txheem xws li kev txhawb nqa hauv tsev, thiab cov khoom siv kho tshuab xws li conveyors thiab twj.
Qhov siab tshaj plaws ua haujlwm siab ntawm ASTM A53 Class B ERW yeeb nkab yog dab tsi?
Qhov siab tshaj plaws ua haujlwm siab ntawmASTM A53 Class B ERW yeeb nkabnyob ntawm tej yam xws li qhov loj, phab ntsa thickness, thiab kub, tab sis feem ntau yog nyob ib ncig ntawm 795 psi (55 bar) ntawm chav tsev kub. Txawm li cas los xij, qhov tshwj xeeb ntsuas siab tuaj yeem sib txawv nyob ntawm qhov ntev ntawm cov yeeb nkab (nominal txoj kab uas hla, sab nraud, phab ntsa thickness / yeeb nkab phab ntsa thickness).
Dab tsi yog txoj kev kho saum npoo rau ASTM A53 Class B siab -frequency resistance welded (ERW) yeeb nkab?
Txoj kev kho deg rauASTM A53 Class B siab -frequency resistance welded (ERW) yeeb nkabsuav nrog cov txheej txheem siv tshuab (xws li sandblasting thiab tua blasting), chemical txoj kev (xws li pickling), thiab tiv thaiv txheej (xws li kub-dip galvanizing, epoxy txheej, thiab xeb- tiv thaiv roj).
Puas yog thaj tsam weld ntawm ASTM A53 Class B siab-frequency resistance welded (ERW) yeeb nkab yuav tsum tau kho tshwj xeeb?
Yog, weld seam ntawmASTM A53 Class B siab -frequency resistance welded (ERW) yeeb nkabyuav tsum tau kev kho mob tshwj xeeb tom qab vuam, hu ua kev kho cua sov, ntawm qhov tsawg kawg nkaus ntawm 1000℃F (540 degree), kom tshem tawm cov martensite untempered thiab xyuas kom cov yeeb nkab ua tau raws li lub zog thiab sealing yuav tsum tau.
