Ipayipi lensimbi elingenamthungo lama-boilers uhlobo lwepayipi le-boiler futhi lingaphansi kwesigaba samapayipi ensimbi angenamthungo. Indlela yokukhiqiza ifana neyamapayipi ensimbi angenamthungo, kodwa kunezidingo eziqinile zohlobo lwensimbi esetshenziswa ekukhiqizeni amapayipi ensimbi. Amapayipi ensimbi angenamthungo ama-boilers avame ukusetshenziswa ngaphansi kwezimo zokushisa okuphezulu kanye nokucindezela okuphezulu. Ngaphansi kwesenzo segesi yokushisa ephezulu kanye nomhwamuko wamanzi, amapayipi azokhipha i-oxidation futhi agqwale. Amapayipi ensimbi ayadingeka ukuthi abe namandla ahlala isikhathi eside, ukumelana okuphezulu ne-oxidation kanye nokugqwala, kanye nokuqina okuhle kwesakhiwo. Amapayipi ensimbi angenamthungo ama-boilers asetshenziswa kakhulu ukwenza amapayipi anomfutho ophezulu, amapayipi amakhulu omusi, njll.

Amashubhu ebhoyila aphansi naphakathiGB3087 kanyeamashubhu angenamthungo ebhoyilaI-GB5310 yizinto ezisezingeni eliphezulu ezisetshenziselwa ukukhiqiza amapayipi omusi ashisayo kakhulu, amapayipi amanzi abilayo ama-boiler aphansi anezingcindezi zezakhiwo ezahlukahlukene, amapayipi omusi ashisayo kakhulu ama-boiler esitimela, amapayipi amakhulu omusi, amapayipi amancane omusi kanye namapayipi ezitini ezigoqekile. Amapayipi ensimbi yesakhiwo sekhabhoni angenamthungo aqhutshwa ngokushisa nadonsayo (agoqekile) adonswa ngokubandayo.Ipayipi lensimbi elingenamthungo lesakhiwo (GB/T8162)ipayipi lensimbi elingenamthungo elisetshenziselwa izakhiwo ezijwayelekile kanye nezakhiwo zemishini.Amapayipi ebhoyila anomfutho ophezulu I-ASME SA-106 (GR.B, GR.C)futhiI-ASTM A210asetshenziselwa amapayipi ebhoyila kanye namapayipi ebhoyila. Amapayipi, kufaka phakathi amapayipi okugcina okuphepha kanye namapayipi e-strut kanye namapayipi amancane ensimbi yekhabhoni ephakathi nendawo angenamthungo yamapayipi e-superheater,I-ASME SA-213, i-ferritic engenamthungo kanye ne-austenitic yama-boiler, ama-superheater kanye nama-heat exchangers Ipayipi lensimbi ye-alloy,I-ASTM A335 P5, P9, P11, P12, P22, P9, P91, P92, ipayipi lensimbi elingenamthungo le-ferritic alloy lokushisa okuphezulu.

Imininingwane kanye nekhwalithi yokubukeka: GB5310-2017 "Ipayipi Lensimbi Elingenamthungo Lama-Boiler Anengcindezi Ephakeme" Ububanzi bangaphandle bamapayipi aguqayo ashisayo bungu-22 kuya ku-530mm, kanti ubukhulu bodonga busukela ku-20 kuya ku-70mm. Ububanzi bangaphandle bamapayipi aguqayo abandayo (aguqayo abandayo) busukela ku-10 kuya ku-108mm, kanti ubukhulu bodonga busukela ku-2.0 kuya ku-13.0mm.

Amashubhu angenamthungo ama-boiler asebenzisa amamaki ensimbi

(1) Amazinga ensimbi yesakhiwo sekhabhoni esezingeni eliphezulu afaka phakathi i-20G, i-20MnG, kanye ne-25MnG.

(2) Amazinga ensimbi yesakhiwo se-alloy15MoG, 20MoG, 12CrMoG,15CrMoG, 12Cr2MoG, 12CrMoVG, njll.
