I. Core Quality Assurance Measures
1. Tsis yog-Kev kuaj kev puas tsuaj Re- kev tshuaj xyuas: thaj chaw kho yuav tsum tau rov ua dua- sim siv ultrasonic kuaj (UT) lossis eddy tam sim no kuaj (ET), tsom rau kev kuaj xyuas qhov seem seem lossis qhov tsis xws luag. Tshwj xeeb tshaj yog tom qab kev sib tsoo thiab tig, nws yog ib qho tsim nyog kom paub meej tias qhov tsis muaj qhov tshiab qaug zog.
2. Hydrostatic Testing los xyuas kom meej sealing: Kev ntsuas siab yuav tsum tau ua ntawm 1.5 npaug ntawm kev ua haujlwm siab tsawg kawg yog 10 vib nas this kom tsis txhob muaj qhov tawg lossis cov yas deformation hauv thaj chaw kho, ua tau raws li GB / T 241-2007 tus qauv.
3. Dimensional Accuracy Verification: Sab nraud txoj kab uas hla thiab phab ntsa thickness ntawm qhov kho qhov chaw yuav tsum tau ntsuas siv cov cuab yeej xws li ib tug ultrasonic thickness gauge thiab micrometer los xyuas kom meej tias cov phab ntsa thickness tsis qis tshaj tus tsim yam tsawg kawg nkaus (feem ntau, nws yuav tsum tsis txhob ntau tshaj qhov tsis zoo sib txawv ntawm 10%), tsis txhob ua kom tsis muaj zog lub siab - bearing muaj peev xwm.
4. Kev tshuaj xyuas qhov zoo ntawm qhov chaw: Qhov chaw kho yuav tsum muaj kev hloov pauv, tsis muaj qhov ntse ntse, qhov taub, lossis cov ntsiab lus siab kom tsis txhob muaj kev ntxhov siab. Sib nqus particle kuaj (MT) yuav tsum tau ua yog tias tsim nyog kom paub meej tias qhov tsis muaj qhov qhib qhov tsis xws luag.
II. Cov qauv siv tau thiab txwv tsis pub siv
1. Raws li GB/T 8163-2023, seamless steel kav siv rau conveying flammable los yog tshuaj lom xov xwm tsis raug tso cai rau undergo tej yam kev kho mob. Yog tias pom qhov tsis xws luag, tag nrho cov yeeb nkab yuav tsum tau muab pov tseg.
2. Kev kho qhov dej ntiav ntawm qhov tsis xws luag hauv qhov tsis yog - siab, qis - cov tshuab siab lossis cov kav dej muaj zog tsuas yog tso cai, thiab tag nrho cov txheej txheem yuav tsum tau sau tseg thiab taug qab.
⚠️ Kev nyab xeeb hauv qab kab: Tsis muaj kev kho yuav raug ua raws li kev nyab xeeb. Kev kho uas muaj qhov tsis xws luag sab hauv (xws li cov folds sab hauv, suav nrog, thiab porosity) lossis kev puas tsuaj yog raug txwv nruj heev.
