JIS G 3454ngumgangatho woshishino waseJapan wemibhobho yentsimbi yekhabhoni kwiinkqubo zoxinzelelo ezinobushushu obuphezulu be-350 ° C.Umgangatho ubandakanya amabanga amabini:STPG 370kwayeSTPG 410.Isebenza kumandla ombane adityanisiweyo (ERW) okanye imibhobho engenamthungo enedayamitha ye-10.5 mm ukuya kuma-660.4 mm (okt 6A ukuya ku-650A, okanye i-1/8B ukuya ku-26B).
I-JIS G 3454 Imibhobho yentsimbi iya kuveliswa ngokusebenzisa ukudibanisa okufanelekileyo kweendlela zokwenza umbhobho wensimbi kunye neendlela zokugqiba kwitheyibhile engezantsi.

Uvavanyo lokucaba
Xa umgama phakathi kwamacwecwe amabini ufikelela kumgama ochaziweyo H, akuyi kubakho ziphene okanye ukuqhekeka ebusweni bombhobho wensimbi.
Kwimibhobho yensimbi engenamthungo: H = (1 + e) t / (e + t / D);
Kwimibhobho yensimbi ye-ERW: H = 1/3 D (ye-weld) okanye i-H = 2/3 D (isahlulo ngaphandle kwe-weld);
H: umgama phakathi kweepleyiti ezicwebezelayo (mm);
е: rhoqo kuchazwe ngamnye kwibakala ngalinye lombhobho, i-0.08 ye-STPG 370, 0.07 ye-STPG 410;
t: ubukhulu bodonga lombhobho (mm);
D: ngaphandle kobubanzi bombhobho (mm);
Uvavanyo lwe-Flattening lusebenza kwimibhobho yentsimbi ene-diameter ye-nominal engaphezu kwe-40A (48.6mm).
Ukubanda
I-Bendability isebenza kwimibhobho ene-diameter ye-40 A (48.6) okanye encinci.
Umbhobho kufuneka ugobe i-90 ° kwi-radius yamaxesha ama-6 ububanzi bayo bangaphandle.Udonga lombhobho kufuneka lungabi naziphene okanye iintanda.
Umbhobho ngamnye wentsimbi kufuneka ube novavanyo loxinzelelo lwe-hydrostatic okanye uvavanyo olungonakalisi.
Uvavanyo lweHydrostatic
Gcina uxinzelelo oluthile ubuncinane imizuzwana emi-5 ngaphandle kokuvuza.
Ixabiso loxinzelelo lihambelana neshedyuli Nombhobho wensimbi.

Uvavanyo olungonakalisi
Ukuba ukuhlolwa kwe-ultrasonic kusetyenziswa, kufuneka kusekelwe kumgangatho ongqongqo kunophawu lweklasi ye-UD kwi-JIS G 0582.
Ukuba uvavanyo lwangoku lwe-eddy lusetyenzisiwe, kufuneka lusekelwe kumgangatho ongqongqo ngakumbi kunophawu lweklasi ye-EY kwi-JIS G 0583.
