I-JIS G 3454ngumgangatho waseJapan wemizi-mveliso wemibhobho yentsimbi yekhabhoni kwiinkqubo zoxinzelelo ezinobushushu obuphezulu bokusebenza obuyi-350°C. Lo mgangatho uquka amanqanaba amabini:I-STPG 370kwayeI-STPG 410Isebenza kwiipayipi ezidityanisiweyo ngombane (ERW) okanye ezingenamthungo ezinobubanzi obuqhelekileyo obuyi-10.5 mm ukuya kwi-660.4 mm (oko kukuthi, ukusuka kwi-6A ukuya kwi-650A, okanye ukusuka kwi-1/8B ukuya kwi-26B).
I-JIS G 3454 Imibhobho yentsimbi mayiveliswe kusetyenziswa indibaniselwano efanelekileyo yeendlela zokwenza imibhobho yentsimbi kunye neendlela zokugqiba ezikwitheyibhile engasezantsi.

Uvavanyo lokuTyatya
Xa umgama phakathi kweepleyiti ezimbini ufikelela kumgama ochaziweyo u-H, akusayi kubakho ziphene okanye imingxunya kumphezulu wombhobho wentsimbi.
Kwiityhubhu zentsimbi ezingenamthungo: H = (1+e)t/(e + t/D);
Kwimibhobho yentsimbi ye-ERW: H = 1/3 D (ye-weld) okanye H = 2/3 D (yenxalenye engena-weld);
H: umgama phakathi kweepleyiti zokucaba (mm);
е: i-constant echazwe ngokwahlukeneyo kwinqanaba ngalinye lombhobho, i-0.08 kwi-STPG 370, i-0.07 kwi-STPG 410;
t: ubukhulu bodonga lombhobho (mm);
D: ububanzi bangaphandle bombhobho (mm);
Uvavanyo lokuGqibela lusebenza kwiipayipi zentsimbi ezinobubanzi obungaphezulu kwe-40A (48.6mm).
Ukugoba
Ukugoba kusebenza kwiipayipi ezinobubanzi obuqhelekileyo obuyi-40 A (48.6) okanye ngaphantsi.
Umbhobho kufuneka ugotywe ngama-90° kwi-radius ephindwe kathandathu ububanzi bawo bangaphandle. Udonga lombhobho kufuneka lungabi naziphene okanye iintanda.
Umbhobho ngamnye wentsimbi kufuneka uvavanywe ngoxinzelelo lwe-hydrostatic okanye uvavanyo olungatshabalalisiyo.
Uvavanyo lwe-Hydrostatic
Gcina uxinzelelo oluthile ubuncinane imizuzwana emi-5 ngaphandle kokuvuza.

Ungacofa kwiNombolo yeshedyuli ofuna ukuyijonga; silungiselele iinguqulelo zePDF ezifanelekileyo ukuze kube lula kuwe.
I-JIS G 3454 Ukunyamezelana kobubanzi bangaphandle, ubukhulu bodonga, ukungaqhelekanga, kunye nobude kuya kuhlangabezana neemfuno ezilandelayo.
Ukususela oko yasekwa ngo-2014, iBotop Steel ibe ngumthengisi ophambili wemibhobho yentsimbi yekhabhoni eMntla China, eyaziwa ngenkonzo egqwesileyo, iimveliso ezikumgangatho ophezulu, kunye nezisombululo ezibanzi.
Le nkampani inikezela ngeendidi ngeendidi zeepayipi zentsimbi yekhabhoni kunye neemveliso ezinxulumene noko, kuquka ipayipi yentsimbi engenamthungo, i-ERW, i-LSAW, kunye ne-SSAW, kunye noluhlu olupheleleyo lwee-fittings zepayipi kunye nee-flanges.
Iimveliso zayo ezikhethekileyo ziquka ii-alloys zodidi oluphezulu kunye neentsimbi ezingenasici ze-austenitic, ezenzelwe ukuhlangabezana neemfuno zeeprojekthi ezahlukeneyo zemibhobho.
Nceda unxibelelane nathi, siza kukunika imibhobho yentsimbi esemgangathweni ophezulu, esemgangathweni, enenkonzo yobungcali nesebenzayo. I-Botop ijonge phambili ekukuncedeni.
