Kev kho cua sov feem ntau ua li cas ntawm ASME SA 333 Gr.6 ERW welded steel yeeb nkab?
Kev kho cua sov ntawmASME SA 333 Gr.6 ERW welded steel yeeb nkabFeem ntau suav nrog normalizing, uas ua kom sov cov yeeb nkab steel rau qhov kub tsis tsawg dua 815℃(1500℃F), thiab tom qab ntawd txias nws hauv huab cua lossis hauv qhov chaw tswj qhov cub cua txias chamber. Yog tias daim ntawv thov lossis tus qauv qhia lwm yam, kev tshaj tawm -weld cua sov yuav tsum tau kho.
Dab tsi yog qhov sib txawv loj tshaj plaws hauv kev tsim khoom ntawm ERW steel yeeb nkab thiab seamless steel yeeb nkab?
Qhov sib txawv loj tshaj yog qhov ntawdERW (tsis kam welded) steel yeeb nkabyog tsim los ntawm dov steel sawb mus rau hauv ib lub raj thiab ces welding ib tug weld raws nws ntev, thaum seamless steel yeeb nkab yog tsim los ntawm tho ib tug steel billet, ces ncab thiab dov nws mus rau hauv lub hollow raj yam tsis muaj vuam.
Yuav ua li cas tsis yog -kev kuaj kev puas tsuaj yuav tsum tau ua kom paub tseeb qhov zoo ntawm ERW welds?
Non-destructive testing (NDT) of resistance welds includes a combination of methods, such as ultrasonic testing (UT) for detecting internal defects, eddy current testing (ECT) for detecting surface and subsurface defects, and visual inspection for detecting surface problems.
Lub hom phiaj ntawm kev ntsuam xyuas hydrostatic ntawm ASME SA 333 Gr.6 ERW welded yeeb nkab yog dab tsi?
Lub hom phiaj ntawm kev sim hydrostatic rauASME SA 333 Gr.6 ERW welded yeeb nkabyog txhawm rau txheeb xyuas nws txoj kev ncaj ncees thiab thauj khoom -cov kabmob muaj peev xwm los ntawm kev siv dej siab dua li nws qhov kev ua haujlwm siab.
Vim li cas cov tshuaj muaj pes tsawg leeg tsom xam ntawm cov khoom siv hauv paus thiab vuam ntawm ERW steel yeeb nkab tsim nyog?
Chemical composition analysis ntawmERW steel yeeb nkabyog ua los xyuas kom meej nws cov weldability thiab kev ncaj ncees ntawm cov khoom kawg los ntawm kev txheeb xyuas tias cov khoom siv hauv paus thiab weld ua tau raws li cov qauv teev tseg.
