Ishubhu elingenamthungo le-boiler liwuhlobo lweshubhu lokubhayela, eliyingxenye yeshubhu lensimbi engenamthungo. Indlela yokukhiqiza iyafana neshubhu engenamthungo, kodwa kunezidingo eziqinile ensimbi esetshenziswa ekwenzeni ishubhu lensimbi. I-boiler ene-tube engenamthungo ivame ukusetshenziswa ekushiseni okuphezulu kanye nezimo zokucindezela okuphezulu, amapayipi egesi yokushisa ephezulu ye-flue kanye nomhwamuko wamanzi ngaphansi kwesenzo, kuzokwenzeka i-oxidation kanye nokugqwala. Amashubhu ensimbi adingeka ukuze abe namandla ahlala isikhathi eside, ukumelana nokugqwala okuphezulu kwe-oxidation, nokuzinza okuhle kwezicubu. I-boiler eneshubhu engenamthungo isetshenziswa kakhulu ukwenza umfutho ophezulu kanye neshubhu ye-boiler ye-ultra-high pressure superheater, ishubhu yokufudumeza kabusha, i-gas guide boiler eneshubhu engenamthungo, ishubhu yesitimu esikhulu, njll.

Ishubhu le-boiler enengcindezi ephansi naphakathiI-GB3087-1999, i-boiler tube engenamthungoI-GB5310-1999isetshenziselwa ukwakha izinhlobonhlobo zezakhiwo ze-low pressure boiler superheated steam pipe, ipayipi lamanzi abilayo kanye nepayipi le-locomotive boiler elishisa kakhulu, ipayipi lentuthu, ipayipi elincane lentuthu kanye nepayipi lepayipi lezitini le-arch lekhwalithi ephezulu ye-carbon structural steel eshisayo egoqwe futhi ebandayo edonswayo (egoqiwe) ipayipi lensimbi engenamthungo. Ishubhu lensimbi elingenamthungo lesakhiwo (I-GB/T8162-1999) iyishubhu yensimbi engenamthungo yesakhiwo esijwayelekile kanye nesakhiwo somshini. Imininingwane nekhwalithi yokubukeka:I-GB5310-95“Ithubhu Lensimbi Elingenamthungo le-High pressure boiler” elishisayo eligoqiwe ububanzi bepayipi elingu-22~530mm, ukujiya kodonga 20~70mm. Ububanzi obungaphandle beshubhu elibandayo elidonswe (eligoqekile elibandayo) lingu-10~108mm, futhi ukujiya kodonga kungu-2.0~13.0mm. Ipayipi lensimbi elingenamthungo elimise okukhethekile yitemu elivamile lepayipi lensimbi engenamthungo lamanye amajamo ahlukene ngaphandle kwepayipi eliyindilinga. Ngokusho kokwakheka okuhlukile nosayizi wesigaba sepayipi lensimbi, ingahlukaniswa ngokulingana odongeni ukujiya ipayipi lensimbi emise okukhethekile emise nekhono (ikhodi D), udonga olungalingani ukujiya ipayipi lensimbi emise okukhethekile nekhono (ikhodi for BD), ububanzi variable ipayipi lensimbi emise okukhethekile nekhono (ikhodi BJ). Amashubhu ensimbi angenamthungo akhethekile asetshenziswa kabanzi ezingxenyeni ezihlukene zesakhiwo, amathuluzi nezingxenye zemishini. Uma kuqhathaniswa neshubhu eliyindilinga, ishubhu elimise okukhethekile ngokuvamile linesikhathi esikhudlwana se-inertia kanye ne-modulus yesigaba, futhi linamandla amakhulu okumelana nokugoba kanye ne-torsion, enganciphisa kakhulu isisindo sesakhiwo futhi yonge insimbi. 4. Ukuhlolwa kokwakheka kwamakhemikhali (1)I-GB3087-82Izinhlinzeko ze-“seamless steel tube for low and medium pressure boiler” izinhlinzeko. Indlela yokuhlola ukwakheka kwamakhemikhali ngokuya nge-GB222-84 kanye ne-GB223 “Indlela Yokuhlaziya Amakhemikhali Ensimbi Nengxubevange” ingxenye efanele. (2)I-GB5310-95Izinhlinzeko ze-“Seamless Steel Tube for High pressure boiler”. Indlela yokuhlola yokwakheka kwamakhemikhali ihambisana nezingxenye ezifanele ze-GB222-84, Indlela Yokuhlaziya Amakhemikhali Yensimbi Nengxubevange, kanye ne-GB223 Chemical Analysis Method yensimbi ne-alloy. (3) Ukuhlolwa kokwakheka kwamakhemikhali kwamashubhu ensimbi kabhayela angenisiwe kuzokwenziwa ngokuvumelana nezindinganiso ezifanele ezishiwo kwinkontileka. I-boiler engu-5 eneshubhu yensimbi engenamthungo (1) insimbi yekhwalithi ephezulu ye-carbon structural steel ingu-20G, 20MnG, 25MnG. (2) ingxubevange yensimbi yesakhiwo engu-15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG12CrMoG12CrMoCr2Br3MoCr3MoCr3MoCr3MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG12CrMoCr2Br3MoCr3Br, 3MoCr3Br kanye ne-3MoVG. (3) ukugqwala ukumelana nokushisa kwensimbi evame ukusetshenziswa 1Cr18Ni9, 1Cr18Ni11Nb kubhayela tube ngaphezu kokuqinisekisa ukwakheka kwamakhemikhali kanye nezakhiwo zemishini, ukwenza i-hydraulic test impande ngempande, ukwenza ukuvutha, ukuhlolwa kokucaba. Amashubhu ensimbi alethwa esimweni sokuphathwa ukushisa. Ngaphezu kwalokho, i-microstructure, usayizi wokusanhlamvu kanye nongqimba lwe-decarbonization wepayipi lensimbi eliqediwe liyadingeka.

I-boiler izindlela zokukhiqiza ishubhu engenamthungoI-boiler enohlobo lweshubhu engenamthungo. Izindlela zokukhiqiza kanye neshubhu engenamthungo ziyefana, kodwa yiba nesicelo esiqinile sokukhiqiza insimbi esetshenziswa epayipini lensimbi. Ngokusho kokusetshenziswa kwezinga lokushisa zingahlukaniswa zibe amashubhu amabili okubhayela okujwayelekile kanye neshubhu lokubhayela elinomfutho ophakeme.1, isifinyezo se(1) indlela yokukhiqiza:(1) izinga lokushisa elijwayelekile leshubhu elingenamthungo elingaphansi kuka-450 ℃, ipayipi elifuywayo ikakhulukazi lisebenzisa i-10, 20 carbon steel hot roll roll or cold drawn tube. umhwamuko, i-oxidation kanye nokugqwala kuzokwenzeka. Izimfuneko zepayipi lensimbi elinamandla amakhulu okuqhekeka, ukumelana nokugqwala okuphezulu kwe-oxidation, futhi kube nokuzinza okuhle kwenhlangano.(2) sebenzisa:(1) ishubhu elivamile le-boiler elingenamthungo lisetshenziselwa ikakhulukazi ukwenza ishubhu yodonga lwamanzi, ipayipi lamanzi, ishubhu lesimusi esishisa kakhulu, ipayipi lesitimela elishisa kakhulu, ipayipi elikhulu nelincane nesitini se-arch, njll. amashubhu we-boiler superheater, ishubhu yokushisa kabusha, ipayipi lesitimu elikhulu lomoya, njll.

Ukusetshenziswa kwe-boiler tube engenamthungo

(1) ishubhu elivamile le-boiler elingenamthungo lisetshenziselwa ikakhulukazi ukwenza amashubhu odongeni lwamanzi, ipayipi lamanzi, ishubhu yesitimu esishisa kakhulu, ipayipi lesitimela esishisa kakhulu esishisayo, ipayipi elikhulu nelincane kanye nesitini se-tube arch, njll.(2) ishubhu elingenamthungo likabhoyela elingenamthungo lisetshenziselwa ikakhulukazi ukwenza amashubhu okushisa aphezulu kanye ne-ultrahigh-pressure kubhayela, ishubhu yokufudumeza, umshini womoya ophansi we-airway3 isitimu838 njll. amashubhu kanye ne-GB5310-95 "i-high pressure boiler boiler seamless steel tube". Ikhwalithi yokubukeka: ishubhu lensimbi ngaphakathi nangaphandle kwendawo ayivunyelwe ukuba nokuqhekeka, ukugoqa, ukugoqa, izibazi, i-delamination kanye nezinwele. Lezi ziphambeko zizosuswa ngokuphelele. Khipha ukuchezuka okunegethivu, ukujula akumele kudlule ukushuba kodonga lokuzisholo ukuhlanzwa kugqinsi lwangempela lodonga akumele kube ngaphansi kwenani eliphansi lokujiya kodonga kuvunyelwe.Indlela yokubala isisindo sethiyori yeshubhu yebhayela engenamthungo: – ukushuba kodonga (ububanzi) * 0.02466 * ukujiya kodonga.
