Kev tshuaj xyuas zoo ntawm aluminium flange lub tes tsho yuav tsum muaj kev tshuaj xyuas los ntawm ntau qhov ntev, nrog rau cov khoom siv, qhov tseeb ntawm qhov chaw, qhov zoo ntawm qhov chaw, kev sib khi kev ntseeg siab, thiab cov txheej txheem sib dhos, kom ntseeg tau tias lawv lub sijhawm ntev - kev nyab xeeb thiab ruaj khov hauv cov khoom siv fais fab. Cov hauv qab no yog cov khoom ntsuas tseem ceeb thiab cov txheej txheem uas tau sau tseg raws li cov qauv kev lag luam (xws li DL / T 5155-2008) thiab kev ua lag luam:
Cov khoom siv ntsuas kev ua haujlwm
Chemical Composition Analysis: Cov khoom sib xyaw ntawm cov khoom siv aluminium flange yog soj ntsuam siv ncaj qha - nyeem ntawv spectrometer lossis X-ray fluorescence spectrometer los xyuas seb nws puas ua tau raws li qhov yuav tsum tau muaj ntawm qib teev tseg xws li 5A02 thiab 6061, nrog rau kev tsom mus rau kev tswj cov ntsiab lus ntawm cov ntsiab lus xws li txhuas, magnesium, siliese.
Mechanical Property Testing
Tensile Strength, Yield Strength, thiab Elongation: Tensile tests yog ua los ntawm kev siv lub tshuab ntsuas universal.
Kev ntsuas hardness: Lub hardness ntawm flange lub cev thiab weld cheeb tsam yog sim siv Brinell los yog Vickers hardness tester los xyuas kom meej uniformity.
Impact Toughness: Charpy V-Kev ntsuas qhov cuam tshuam yog ua rau qhov kub thiab txias los ntsuas cov khoom siv tawv.
Dimensional and Geometric Tolerance Inspection Key dimensions xws li sab nraud, sab hauv txoj kab uas hla, flange thickness, thiab bolt qhov nruab nrab lub voj voog txoj kab uas hla yuav tsum raug ntsuas kom raug siv lub digital caliper, micrometer, los yog kev sib koom tes ntsuas tshuab.
The perpendicularity deviation between the flange end face and the pipe shaft should meet the following requirements: no more than 1mm for DN≤300mm, and no more than 2mm for DN>300 hli.
Qhov tseeb ntawm qhov chaw ntawm lub qhov ntsia hlau, qhov flatness ntawm sealing nto, thiab parallelism kuj yuav tsum tau nruj me ntsis tswj kom tsis txhob muaj misalignment thaum sib dhos.
