Yintoni i-ASTM 210/ASME SA210 iBanga C?

I-ASTM A210 iBanga C (ASME SA210 iBanga C) yityhubhu yentsimbi ephakathi kwekhabhoni engenamthungo eyenzelwe ngokukodwa ukusetyenziswa ekwenzeni iityhubhu zebhoyila kunye nemibhobho yebhoyila, kuquka iziphelo zokhuseleko, udonga lwesithando somlilo kunye neetyhubhu zenkxaso, kunye neetyhubhu zeheater.

IBanga C linezinto ezintle zemishini, kunye namandla okunyamezela kwe-MPa ye-485 kunye namandla okuvelisa i-MPa ye-275. Ezi zakhiwo, kunye nokwakheka kweekhemikhali ezifanelekileyo, zenza iibhubhu ze-ASTM A210 zeBanga le-C zilungele ukusetyenziswa kwiindawo eziphezulu zokushisa kunye noxinzelelo oluphezulu kwaye zikwazi ukumelana noxinzelelo oluveliswa yi-boiler operation.

Iinkqubo Zokuvelisa

Iityhubhu ziya kwenziwa yinkqubo engenamthungo kwaye iya kutshisa okanye igqitywe ngokubanda.

Apha ngezantsi kukho itshati yenkqubo yokwenziwa kombhobho wentsimbi ongenamthungo ogqitywe ngokubanda:

Inkqubo yokwenza umbhobho wentsimbi ongenamthungo otsalwa ngokubanda

Ke yintoni umahluko phakathi kombhobho wentsimbi ongenamthungo ogqityiweyo kunye nogqitywe ngokubanda kwaye ukhetha njani?

Ishushu-igqityiweumbhobho wensimbi ongenamthungo ngumbhobho wentsimbi oqengqelekayo okanye ohlatywe kubushushu obuphezulu kunye nezinye iinkqubo kwaye emva koko upholiswe ngokuthe ngqo kwiqondo lokushisa. Imibhobho yentsimbi kweli lizwe idla ngokuba nobungqongqo obungcono kunye nokomelela okuthile, kodwa umgangatho womphezulu usenokungabi mhle njengemibhobho yentsimbi egqitywe ngokubanda kuba inkqubo yonyango lobushushu inokukhokelela kwi-oxidation okanye ukususwa kwecarburization kumphezulu wombhobho wentsimbi.

Kubanda-kugqityiweumbhobho wentsimbi ongenamthungo ubhekisa kulungiso lokugqibela lombhobho wentsimbi ngokuzoba okubandayo, ukuqengqeleka okubandayo, kunye nezinye iinkqubo kwiqondo lobushushu begumbi. Umbhobho wensimbi ogqityiweyo obandayo unokuchaneka okuphezulu okuphezulu, kunye nomgangatho omhle womphezulu, kwaye ngenxa yokuba ukusetyenzwa okubandayo kunokuphucula amandla kunye nobunzima bombhobho wentsimbi, iimpawu zomatshini wombhobho wentsimbi ogqityiweyo udla ngokuba ngcono kunombhobho wentsimbi ogqityiweyo. Nangona kunjalo, umlinganiselo othile wokuxinezeleka okushiyekileyo unokuveliswa ngaphakathi kwipayipi yensimbi ngexesha lokusebenza okubandayo, okufuneka kupheliswe ngonyango olulandelayo lokutshisa.

Unyango lobushushu

Umbhobho wentsimbi ogqityiweyo oshushu awufuni unyango lobushushu.

Iityhubhu ezigqityiweyo ezibandayo ziya kufakwa kwi-subcritical annealed, i-annealed ngokupheleleyo, okanye ubushushu obuqhelekileyo buphathwe emva kwenkqubo yokugqiba ebandayo.

Umbhobho ngamnye wentsimbi uya kufakwa kuvavanyo loxinzelelo lwe-hydrostatic okanye uvavanyo lombane olungonakaliyo.

Iimfuno zovavanyo ezinxulumene noxinzelelo lwe-Hydrostatic zihambelana ne-ASTM 450, into engama-24.

Iimfuno zovavanyo ezingonakalisi ezinxulumene nombane zihambelana ne-ASTM 450, into engama-26.

Ukwenza imisebenzi

Imisebenzi yokuqulunqa iyimfuneko kwiityhubhu zebhoyili ukuqinisekisa ukuba iibhubhu zihlangabezana neemfuno ezithile zenkqubo yebhoyila.

Xa ifakelwe kwibhoyila, iityhubhu ziya kuma zinwebeka kwaye zihonjiswe ngaphandle kokubonisa iintanda okanye iziphene. Xa zisetyenziswe ngokufanelekileyo, iityhubhu zeheater enkulu ziya kuma zonke zisenziwa. ukuwelda. kunye nokugoba imisebenzi eyimfuneko kwisicelo ngaphandle kokuphuhlisa iziphene.

Ukwenza imisebenzi

IBotop Steel ngumvelisi wemibhobho yentsimbi edityanisiweyo ekumgangatho ophezulu wekhabhoni kunye nomthengisi ovela eTshayina, kunye nombhobho wentsimbi ongenamthungo wesitokhwe, ekubonelela ngomgangatho ophezulu, osemgangathweni kunye nombhobho wentsimbi okhuphisanayo.
