Umbhobho wentsimbi engenamthungo weebhoyila luhlobo lombhobho webhoyila kwaye ungowodidi lweebhoyila zentsimbi engenamthungo. Indlela yokuvelisa iyafana neyeebhoyila zentsimbi engenamthungo, kodwa kukho iimfuno ezingqongqo zohlobo lwentsimbi esetyenziswa ekwenzeni iibhoyila zentsimbi. Iibhoyila zentsimbi ezingenamthungo zeebhoyila zihlala zisetyenziswa phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu. Phantsi kwesenzo segesi yomoya oshushu ophezulu kunye nomphunga wamanzi, iibhoyila ziya kunyibilika kwaye zibole. Iibhoyila zentsimbi kufuneka zibe namandla ahlala ixesha elide, ukumelana okuphezulu ne-oxidation kunye nokugqwala, kunye nozinzo oluhle lwesakhiwo. Iibhoyila zentsimbi ezingenamthungo zeebhoyila zisetyenziselwa ikakhulu ukwenza iibhoyila ezinoxinzelelo oluphezulu, iibhoyila eziphambili zomphunga, njl.njl.

Iityhubhu zebhoyila eziphantsi neziphakathiGB3087 kunyeiityhubhu zebhoyila ezingenamthungoI-GB5310 zizixhobo ezisemgangathweni ophezulu ezisetyenziselwa ukwenza imibhobho yomphunga eshushu kakhulu, imibhobho yamanzi abilayo yeebhoyila ezinoxinzelelo oluphantsi lwezakhiwo ezahlukeneyo, imibhobho yomphunga eshushu kakhulu yeebhoyila zeelocomotive, imibhobho yomsi emikhulu, imibhobho yomsi emincinci kunye nemibhobho yezitena ze-arch. Intsimbi yesakhiwo sekhabhoni eqengqelekayo eshushu netsalwa kubanda (eqengqelekayo) imibhobho yentsimbi engenamthungo.Umbhobho wesinyithi ongenamthungo wesakhiwo (GB/T8162)ngumbhobho wentsimbi ongenamthungo osetyenziselwa izakhiwo eziqhelekileyo kunye nezakhiwo zoomatshini.Imibhobho yebhoyila enoxinzelelo oluphezulu I-ASME SA-106 (GR.B, GR.C)kwayeI-ASTM A210zisetyenziselwa imibhobho yebhoyila kunye nemibhobho yebhoyila. Iityhubhu, kuquka i-safety end vault kunye neetyhubhu ze-strut kunye nobukhulu obuncinci bodonga, iityhubhu zentsimbi yekhabhoni ephakathi engenamthungo, zeetyhubhu ze-superheater,I-ASME SA-213, i-ferritic engenamthungo kunye ne-austenitic kwiibhoyila, ii-superheaters kunye nee-heat exchangers Umbhobho wentsimbi ye-alloy,I-ASTM A335 P5, P9, P11, P12, P22, P9, P91, P92, umbhobho wentsimbi engenamthungo ye-ferritic alloy yobushushu obuphezulu.

Iinkcukacha kunye nomgangatho wembonakalo: GB5310-2017 "Ipayipi yentsimbi engenamthungo yeebhoyila ezixinezelekileyo eziphezulu" Ububanzi bangaphandle beepayipi eziqengqelekayo ezishushu buyi-22 ukuya kwi-530mm, kwaye ubukhulu bodonga buphakathi kwe-20 ukuya kwi-70mm. Ububanzi bangaphandle beepayipi ezitsalwa ngokubandayo (eziqengqelekayo ezibandayo) buphakathi kwe-10 ukuya kwi-108mm, kwaye ubukhulu bodonga buphakathi kwe-2.0 ukuya kwi-13.0mm.

Iityhubhu ezingenamthungo zeebhoyila zisebenzisa amanqanaba entsimbi

(1) Iindidi zentsimbi yesakhiwo sekhabhoni ekumgangatho ophezulu ziquka i-20G, i-20MnG, kunye ne-25MnG.

(2) Amanqanaba entsimbi yesinyithi ye-alloy eyakhiweyo15MoG, 20MoG, 12CrMoG,15CrMoG, 12Cr2MoG, 12CrMoVG, njl.njl.
