JIS G 3454ni kiwango cha viwanda cha Kijapani cha mabomba ya chuma cha kaboni kwa mifumo ya shinikizo yenye kiwango cha juu cha joto cha 350 ° C.Kiwango ni pamoja na madaraja mawili:STPG 370naSTPG 410.Inatumika kwa upinzani wa umeme ulio svetsade (ERW) au mabomba ya imefumwa yenye kipenyo cha kawaida cha 10.5 mm hadi 660.4 mm (yaani 6A hadi 650A, au 1/8B hadi 26B).
Mabomba ya chuma ya JIS G 3454 yatatengenezwa kwa kutumia mchanganyiko unaofaa wa mbinu za utengenezaji wa mabomba ya chuma na njia za kumaliza katika jedwali hapa chini.

SC: Bomba la chuma la kumaliza baridi la kumaliza;
EH: Moto-kumaliza upinzani wa umeme svetsade bomba la chuma;
EC: Upinzani wa baridi wa kumaliza umeme svetsade bomba la chuma;
EG: Upinzani wa umeme ulio svetsade bomba la chuma isipokuwa zile zilizomalizika moto na zilizomalizika kwa baridi.
Chuma cha Botopni mtengenezaji na muuzaji wa mabomba ya chuma ya kaboni yaliyosocheshwa ya ubora wa juu kutoka China, pamoja na muuzaji wa mabomba ya chuma isiyo imefumwa.Ikiwa una mahitaji yoyote, tafadhali jisikie huru kuwasiliana nasi na tutakupa usaidizi wa kiufundi wa kitaalamu bila malipo.

Mtihani wa Kutandaza
Wakati umbali kati ya sahani mbili kufikia umbali maalum H, hakutakuwa na kasoro au nyufa kwenye uso wa bomba la chuma.
Kwa zilizopo za chuma zisizo imefumwa: H = (1 + e) t / (e + t / D);
Kwa mabomba ya chuma ya ERW: H = 1/3 D (kwa weld) au H = 2/3 D (kwa sehemu bila weld);
H: umbali kati ya sahani za gorofa (mm);
е: mara kwa mara hufafanuliwa kibinafsi kwa kila daraja la bomba, 0.08 kwa STPG 370, 0.07 kwa STPG 410;
t: unene wa ukuta wa bomba (mm);
D: kipenyo cha nje cha bomba (mm);
Jaribio la Kutandaza linatumika kwa mabomba ya chuma yenye kipenyo cha kawaida zaidi ya 40A (48.6mm).
Bendability
Bendability inatumika kwa mabomba yenye kipenyo cha kawaida cha 40 A (48.6) au ndogo.
Bomba linapaswa kupigwa 90 ° kwenye eneo la mara 6 la kipenyo chake cha nje.Ukuta wa bomba lazima usiwe na kasoro au nyufa.
Kila bomba la chuma lazima lipate mtihani wa shinikizo la hydrostatic au mtihani usio na uharibifu.
Mtihani wa Hydrostatic
Weka shinikizo fulani kwa angalau sekunde 5 bila kuvuja.
Thamani ya shinikizo inahusiana na ratiba Nambari ya bomba la chuma.

Iwapo ukaguzi wa ultrasonic utatumika, unapaswa kutegemea kiwango kali zaidi kuliko mawimbi ya darasa la UD katika JIS G 0582.
Iwapo jaribio la sasa la eddy litatumika, linapaswa kutegemea kiwango ambacho ni kigumu zaidi kuliko mawimbi ya darasa la EY katika JIS G 0583.
