Ipayipi lensimbi elingenamthungo lama-boilers liwuhlobo lwepayipi elibilisa futhi liyingxenye yamapayipi ensimbi angenamthungo. Indlela yokukhiqiza iyafana neyamapayipi ensimbi angenamthungo, kodwa kunezidingo eziqinile zohlobo lwensimbi olusetshenziswa ekukhiqizeni amapayipi ensimbi. Amapayipi ensimbi angenamthungo ama-boilers avame ukusetshenziswa ngaphansi kokushisa okuphezulu nezimo ezicindezelayo. Ngaphansi kwesenzo sokushisa okuphezulu kwegesi ye-flue kanye nomhwamuko wamanzi, amapayipi azokhipha i-oxidize futhi agle. Amapayipi ensimbi adingeka ukuthi abe namandla ahlala njalo, ukumelana okuphezulu ne-oxidation nokugqwala, kanye nokuzinza okuhle kwesakhiwo. Amapayipi ensimbi angenamthungo ama-boilers asetshenziselwa ikakhulukazi ukwenza amapayipi anengcindezi ephezulu, amapayipi amakhulu we-steam, njll.

Amashubhu boiler anomfutho ophansi naphakathiGB3087 futhiamashubhu e-boiler angenamthungoI-GB5310 yizinto eziseqophelweni eliphezulu ezisetshenziselwa ukukhiqiza amapayipi esitimu ashisa kakhulu, amapayipi amanzi abilayo amaboilers anengcindezi ephansi yezakhiwo ezahlukahlukene, amapayipi esitimu ashisa kakhulu amabhoyela esitimela, amapayipi amakhulu entuthu, amapayipi amancane entuthu kanye namapayipi esitini esikhothamo. Insimbi yesakhiwo sekhabhoni amapayipi ensimbi ashisayo ashibilike nadonswa kubanda (aginqike).Ipayipi lensimbi elingenamthungo (GB/T8162)iyipayipi lensimbi elingenamthungo elisetshenziselwa izakhiwo ezijwayelekile kanye nezakhiwo zemishini.Amapayipi obhayela anomfutho ophezulu I-ASME SA-106 (GR.B, G.C)futhiI-ASTM A210asetshenziselwa amapayipi obhayela kanye namapayipi okubhayela. Amashubhu, okuhlanganisa ukuphepha kwe-vault kanye namashubhu e-strut kanye nogqinsi oluncanyana lwamashubhu ensimbi angenamthungo aphakathi nendawo wamashubhu okushisa aphezulu,I-ASME SA-213, i-ferritic engenamthungo ne-austenitic yamabhayela, ama-superheaters nezishintshisi zokushisa Ipayipi lensimbi ye-alloy,I-ASTM A335 P5, P9, P11, P12, P22, P9, P91, P92, ferritic ingxubevange nekhono ipayipi insimbi lokushisa eliphezulu.

Ukucaciswa kanye nekhwalithi yokubukeka: I-GB5310-2017 "Ipayipi Lensimbi Elingenamthungo Lama-Boiler Acindezela Kakhulu" Ububanzi bangaphandle bamapayipi ashisayo bungu-22 kuya ku-530mm, futhi ukujiya kodonga kusuka ku-20 kuya ku-70mm. Ububanzi bangaphandle bamapayipi adonswa ngokubanda (abandayo) busukela ku-10 kuye ku-108mm, futhi ukujiya kodonga busukela ku-2.0 kuye ku-13.0mm.

Amashubhu angenamthungo obhayela athatha amamaki ensimbi
