Machubu a boilerndi mapaipi omwe amagwiritsidwa ntchito kutengera zofalitsa mkati mwa boiler, zomwe zimagwirizanitsa mbali zosiyanasiyana za boiler kuti zitheke kutentha kutentha.Machubu awa akhoza kukhalaopanda msoko kapena welded zitsulo machubundipo amapangidwacarbon steel, aloyi chitsulo, kapena chitsulo chosapanga dzimbirikutengera kutentha, kupanikizika, ndi mankhwala a sing'anga yomwe ikunyamulidwa.
Mitundu ya Boiler Tube
Madzi utakhazikika khoma chubu: Yokhala mu chipinda chowotchera, imatenga mwachindunji kutentha kwa lawi ndi mpweya wotentha kwambiri mu ng'anjo ndikutenthetsa madzi kukhala nthunzi.
Chotenthetsera chubu: Amagwiritsidwa ntchito kutenthetsa nthunzi yochuluka yopangidwa ndi boiler mu nthunzi yotentha kwambiri ndikuwonjezera kutentha kwa nthunzi kuti ikwaniritse zosowa za mafakitale kapena kupanga magetsi.
Reheater chubu: Mu makina opangira nthunzi, amagwiritsidwa ntchito kutenthetsanso nthunzi yomwe yagwira ntchito kuti awonjezere kutentha ndi mphamvu ya nthunzi.
chubu chopulumutsa malasha: Yopezeka mu chitoliro kumapeto kwa boiler, imagwiritsidwa ntchito kutenthetsa madzi omwe amalowa mu boiler kuti achepetse kugwiritsa ntchito mafuta a boiler.
Chotolera chubu: Amagwiritsidwa ntchito polumikiza machubu opopera ku boiler kuti atolere kapena kugawa madzi kapena nthunzi kuchokera mu boiler.
Zopangira Boiler Tube
Izi zikuphatikizapo machubu a carbon steel, alloy steel chubu, ndi machubu achitsulo chosapanga dzimbiri.Kusankhidwa kwa zinthu kumadalira momwe ntchito yopangira boiler ikuyendera, kuphatikizapo kutentha, kupanikizika ndi mankhwala a sing'anga.
Mpweya wachitsulo wa carbon: Chitoliro chachitsulo cha kaboni ndi chubu chomwe chimagwiritsidwa ntchito nthawi zambiri popanga media osalowerera kapena ofooka acidic, komanso malo apakati mpaka otsika.Mpweya wachitsulo chitoliro uli ndi zida zabwino zamakina ndi ntchito zowotcherera, mtengo wake ndi wotsika.
Aloyi chitsulo chitoliro: Aloyi zitsulo chitoliro zachokera carbon zitsulo ndi zinthu zina aloyi, monga chromium, faifi tambala, molybdenum, etc., kusintha kukana kutentha, kukana dzimbiri, ndi katundu makina zitsulo.Chitoliro chachitsulo cha aloyi ndi choyenera kutentha kwambiri, kuthamanga kwambiri, ndi malo owononga.
Chitoliro chachitsulo chosapanga dzimbiri: Chitoliro chachitsulo chosapanga dzimbiri chili ndi zinthu zambiri za chromium, chili ndi kukana kwa dzimbiri, ndipo ndichoyenera kukhala ndi asidi amphamvu, alkali, komanso malo otentha kwambiri.Machubu achitsulo chosapanga dzimbiri ndi okwera mtengo kwambiri, koma kulimba kwawo ndi kudalirika kwawo kumawapangitsa kukhala zinthu zosankhidwa pamafakitale ambiri.
Njira Zopangira
Njira zopangira machubu a boiler zimagawika m'maguluopanda msoko ndi welded.
Chigamulo chogwiritsa ntchitoopanda msokokapena machubu achitsulo otenthedwa ayenera kupangidwa potengera momwe chotenthetsera chikuyendera, kuchuluka kwa kutentha, kuchuluka kwa kutentha, ndi mtengo wake.
Kwa ma boilers othamanga kwambiri komanso otentha kwambiri, machubu achitsulo osasunthika nthawi zambiri amasankhidwa kuti atsimikizire chitetezo ndi kudalirika, pomwe ma boilers otsika komanso apakatikati, machubu achitsulo amatha kukhala okwera mtengo kwambiri.

Zina Njira Zina
Kuphatikiza pamiyezo yomwe yatchulidwa pamwambapa kuti igwiritsidwe ntchito m'ma boilers, milingo ina yambiri nthawi zina imagwiritsidwa ntchito popanga machubu a boiler.
Mwachitsanzo, ASTM A53, ASTM A106, ASTM A335, ASTM A312, DIN 17175, EN 10216-2 ndi JIS G 3458.
Kodi Makulidwe a Boiler Tubes Ndi Chiyani?
Pamitundu yosiyanasiyana yamachubu a boiler, kukula kwake kumatha kusiyanasiyana.
Machubu ambiri otenthetsera amakhala ndi mainchesi ang'onoang'ono akunja, pomwe makulidwe a khoma amasankhidwa potengera kukakamiza kogwirira ntchito komanso mawonekedwe amakina azinthuzo.
Mwachitsanzo, muyezo wa ASTM A192 ndi wamachubu achitsulo opanda mpweya wa carbon ndi m'mimba mwake wa 1/2 mpaka 7 in. (12.7 mm mpaka 177.8 mm) ndi makulidwe a khoma a 0.085 mpaka 1 in. 25.4 mm).
Kodi Pali Kusiyana Kotani Pakati pa Machubu a Boiler ndi Machubu Achitsulo?
Machubu a boiler ndi mtundu wa chitoliro, koma adapangidwa kuti azigwiritsidwa ntchito mwachindunji ndi ma boilers ndipo amakhala ndi mapangidwe okhwima komanso zofunikira zakuthupi.Komano, ma chubu ndi mawu odziwika bwino omwe amakhudza mapaipi onse omwe amagwiritsidwa ntchito kunyamula madzi, kuphatikiza koma osangokhala ndi machubu a boiler.
Zambiri zaife
Chiyambireni kukhazikitsidwa mu 2014, Botop Steel yakhala ikugulitsa chitoliro chachitsulo cha carbon ku Northern China, chomwe chimadziwika ndi ntchito zabwino kwambiri, zinthu zamtengo wapatali, komanso zothetsera mavuto.
Kampaniyi imapereka mapaipi osiyanasiyana a zitsulo za carbon ndi zinthu zomwe zimagwirizana nazo, kuphatikizapo zopanda msoko, ERW, LSAW, ndi chitoliro chachitsulo cha SSAW, komanso mzere wathunthu wazitsulo ndi flanges.Zopangira zake zapadera zimaphatikizanso ma alloys apamwamba kwambiri ndi zitsulo zosapanga dzimbiri za austenitic, zopangidwa kuti zikwaniritse zofunikira zama projekiti osiyanasiyana a mapaipi.
