STPT 370ni urwego rwabayapani rusanzwe JIS G 3456 kumiyoboro yicyuma cya karubone, ikoreshwa mumiyoboro yumuvuduko mubidukikije bifite ubushyuhe buri hejuru ya 350 ° C.Irashobora kuba imiyoboro idafite ubudodo cyangwa gusudira hakoreshejwe uburyo bwo gusudira amashanyarazi (ERW).Imiterere yubukanishi bwibikoresho bya STPT 370 nimbaraga ntarengwa zingana na 370 MPa nimbaraga ntoya ya 215 MPa.
Niba ushaka uwukora nuwutanga imiyoboro yicyuma yujuje ubuziranenge bwa JIS G 3456, noneho turi abafatanyabikorwa ushaka.Twandikire uyu munsi kandi tuzishimira kugufasha!
Bikwiranye na diametre yo hanze 10.5 mm - 660.4 mm (6A - 650A) (1 / 8B - 26B).
A na B nuburyo bubiri bwo kwerekana diameter nominal murwego rwabayapani.By'umwihariko, A ihuye na DN, naho B ihuye na NPS.
JIS G 3456 STPT 370 irashobora kubyazwa umusaruro ukoreshejenta nkomyiinzira yo gukora cyangwagusudira amashanyarazi(ERW) inzira.
Ibikorwa byo gukora nabyo bihuye nuburyo butandukanye bwo kurangiza kugirango duhangane nibidukikije bitandukanye.

Birakwiriye imiyoboro yicyuma ifite diameter yo hanze ya mm 60.5 cyangwa munsi yayo.
Iyo icyitegererezo cyunamye hafi ya mandel kugeza kuri radiyo y'imbere inshuro 6 z'umurambararo w'inyuma y'umuyoboro, icyitegererezo kirasuzumwa kandi ntihaboneka ibice.

Uburyo busanzwe bwo kudasenya burimo ibizamini bya ultrasonic (UT) hamwe na eddy igerageza (ET).
Mugihe ukora igenzura rya ultrasonic, hagomba kwerekanwa kuri JIS G 0582, kandi mugihe ibisubizo byubugenzuzi bingana cyangwa birenze ibipimo ngenderwaho byicyiciro cya UD, bifatwa nkibitsinzwe.

Kuva yashingwa mu 2014,Botop Steelyabaye umuyobozi wambere utanga imiyoboro ya karubone mumajyaruguru yUbushinwa, izwiho serivisi nziza, ibicuruzwa byiza, nibisubizo byuzuye.
Isosiyete itanga imiyoboro inyuranye y’ibyuma bya karubone n’ibicuruzwa bifitanye isano na byo, birimo icyuma, ERW, LSAW, hamwe n’icyuma cya SSAW, ndetse n’umurongo wuzuye w’ibikoresho bya flanges na flanges.Ibicuruzwa byayo bidasanzwe birimo kandi amavuta yo mu rwego rwo hejuru hamwe na austenitis ibyuma bitagira umuyonga, bigenewe guhuza ibyifuzo byimishinga itandukanye.
Nyamuneka nyamuneka kutwandikira kandi tuzishimira gusubiza ibibazo byawe.
