Machubu osinthira kutentha a U bend amagwiritsidwa ntchito kwambiri mu zosinthira kutentha za chipolopolo ndi chubu, zokondetsa, ndi makina osamutsa kutentha m'mafakitale. Machubu awa amapindidwa mwapadera kukhala mawonekedwe a U, zomwe zimathandiza kuti malekezero onse awiri a chubu alumikizane ndi pepala limodzi la chubu. Kapangidwe kameneka kamapangitsa kuti kapangidwe ka zida kakhale kosavuta komanso kumawonjezera mphamvu yokulitsa kutentha kwa machubu panthawi yogwira ntchito.
Popeza zosinthira kutentha nthawi zambiri zimagwira ntchito kutentha kwambiri komanso kupanikizika, ubwino ndi kulondola kwa machubu opindika a U ndizofunikira kwambiri.Machubu osinthira kutentha a U-bendiyenera kupereka kulondola kwabwino kwambiri, malo opindika bwino, komanso mphamvu zamakina kuti iwonetsetse kuti ikugwira ntchito bwino m'malo ovuta kwambiri m'mafakitale.
Womic Steel ndi katswiri wopanga machubu a U bendakatswiri pakupanga Machubu osinthira kutentha a U bend osasinthika, machubu olondola okokedwa ozizira, ndi machubu osinthira kutentha opangidwa mwamakondapa ntchito zamafakitale padziko lonse lapansi. Ndi zida zopangira zapamwamba komanso njira zowongolera bwino kwambiri, Womic Steel imapereka mayankho a U bend chubu chapamwamba omwe amagwiritsidwa ntchito m'mafakitale amagetsi, malo opangira mafuta, ndi makina osinthira kutentha m'mafakitale oyeretsera.
Zosinthira kutentha ndi zida zofunika kwambiri m'mafakitale ambiri. Zimasamutsa kutentha pakati pa madzi awiri pamene zimalekanitsidwa, zomwe zimathandiza kukonza mphamvu zogwiritsira ntchito bwino komanso kuwongolera njira. Mu zosinthira kutentha za chipolopolo ndi chubu, machubu mazana kapena zikwizikwi amatha kuyikidwa mkati mwa chipolopolo chozungulira.
Kugwiritsa ntchitoMachubu opindika a Uimalola malekezero onse awiri a chubu chilichonse kuyikidwa pa chubu chimodzi, zomwe zimapangitsa kuti kapangidwe ka zida kakhale kosavuta komanso kuchepetsa ndalama zopangira. Kuphatikiza apo, mawonekedwe a U amalola chubu kukula ndi kupindika panthawi ya kusintha kwa kutentha popanda kupangitsa kuti chubu chikhale chopanikizika kwambiri.
Chifukwa cha zabwino izi,Zosinthira kutentha kwa chubu cha Uamagwiritsidwa ntchito kwambiri m'mafakitale monga kupanga magetsi, kukonza mafuta, kuyeretsa mafuta, komanso kupanga mankhwala.
Kupanga machubu a U bend abwino kwambiri kumafuna njira zingapo zolondola zopangira. Njirayi imayamba ndi kupanga machubu owongoka opanda msoko malinga ndi zofunikira pa zinthu ndi kulekerera kwa miyeso.
Machubu owongoka awa nthawi zambiri amapangidwa pogwiritsa ntchitonjira zojambulira zotentha komanso zoziziraMachubu okokedwa ozizira nthawi zambiri amakondedwa pakugwiritsa ntchito zosinthira kutentha chifukwa amapereka kulondola kwabwino komanso kutsirizika bwino kwa pamwamba.
Machubu owongoka akapangidwa ndikuyang'aniridwa, amatumizidwa ku malo opindirira machubu. Njira yopindirira iyenera kuyendetsedwa mosamala kuti isasinthe mawonekedwe, kuchepeta khoma, kapena zolakwika pamwamba.
ZachizoloweziNjira yopangira chubu cha U bendzikuphatikizapo njira zotsatirazi:
Kupanga chubu cholunjika
Kuyang'anira zinthu ndi kutsimikizira magawo
Kupinda mozizira pogwiritsa ntchito makina apadera opinda
Chithandizo cha kutentha ngati pakufunika
Kuyang'ana komaliza kwa magawo
Kuyesa kosawononga
Pakupindika, chubucho chiyenera kukhala ndi makulidwe ofanana a khoma lonse lopindika. Kuchepa kwambiri kapena kusinthasintha kungachepetse kukana kwa kupanikizika kwa chubucho komanso mphamvu ya makina.
Womic Steel imagwiritsa ntchito zida zapamwamba zopindika machubu kuti ipange machubu osinthira kutentha a U bend opanda mipata okhala ndi mawonekedwe olondola komanso abwino nthawi zonse.Kampaniyo imatha kupanga machubu a U okhala ndi ma radii osiyanasiyana opindika malinga ndi zomwe makasitomala akufuna.
Miyezo ingapo yapadziko lonse lapansi imagwiritsidwa ntchito kwambiri pamachubu osinthira kutentha a U bend. Kusankha kwa zinthu kumadalira kutentha komwe kumagwiritsidwa ntchito, kuthamanga, ndi dzimbiri la makina osinthira kutentha.
Tebulo lotsatirali likuwonetsa zina zomwe zimafalazipangizo zomwe zimagwiritsidwa ntchito pa machubu osinthira kutentha a U bend.
| Muyezo | Giredi | Mtundu wa Zinthu | Ntchito Yachizolowezi |
| ASTM A179 | Chitsulo cha Kaboni | Machubu osinthira kutentha | Zosinthira kutentha zamafakitale |

| ASTM A213 | TP304 / TP316 | Chitsulo chosapanga dzimbiri | Malo owononga |
Pakati pa zinthu zimenezi,Machubu opanda msoko a ASTM A179amagwiritsidwa ntchito kwambiri pa ntchito zosinthira kutentha chifukwa zimapereka mphamvu yabwino yosamutsa kutentha komanso kugwiritsa ntchito bwino ndalama.
Pa makina opanikizika kwambiri,Machubu a chitsulo cha kaboni a ASTM A192 ndi ASTM A210nthawi zambiri amagwiritsidwa ntchito mu zida za boiler ndi heat exchanger.
Mu malo otentha kwambiri, zipangizo zachitsulo monga alloyASTM A213 T11 ndi T22kupereka kukana bwino kwa kukwawa ndi okosijeni.
Ngati pakufunika kukana dzimbiri, chitsulo chosapanga dzimbiri mongaASTM A213 TP304 ndi TP316nthawi zambiri amasankhidwa.
Kuwonjezera pa kusankha zinthu, kukula kwa chubu ndi chinthu china chofunikira kwambiri pakupanga chosinthira kutentha. M'mimba mwake wa chubu, makulidwe a khoma, ndi utali wopindika ziyenera kuyendetsedwa mosamala kuti zitsimikizire kuti zayikidwa bwino komanso kuti kutentha kusamutsidwa bwino.
Gome lotsatirali likuwonetsa zachizoloweziU bend kutentha exchanger chubu kukula.

Theutali wopindikaMachubu a U nthawi zambiri amatsimikiziridwa ndi kapangidwe ka zida. Ma radii ozungulira ofanana amakhala kuyambiraKuchulukitsa nthawi 1.5 mpaka 3 kuposa m'mimba mwake wa chubu chakunja.
Kuti zitsimikizire kuti zinthu zili bwino, machubu a U bend ayenera kuyesedwa mosamala. Njirazi zimathandiza kutsimikizira kuti machubuwo akukwaniritsa zofunikira za kukula ndi miyezo ya zinthu pambuyo popinda.
Njira zowunikira zomwe zimachitika nthawi zambiri zimaphatikizapo:
Kuyesa kwa Ultrasonic kwa zolakwika zamkati
Kuyesa kwa Eddy current kuti aone zolakwika pamwamba
Kuyesa kwa kuthamanga kwa madzi
Kuyang'anira miyeso
Kusanthula kapangidwe ka mankhwala
At Chitsulo cha Womic, gulu lililonse la machubu osinthira kutentha a U bend amayesedwa bwino asanatumizidwe. Zipangizo zoyesera zapamwamba komanso mainjiniya odziwa bwino ntchito amaonetsetsa kuti chubu chilichonse chikugwirizana ndi miyezo yapadziko lonse lapansi komanso zofunikira pa ntchitoyo.
Machubu osinthira kutentha a U bend amagwiritsidwa ntchito kwambiri m'mafakitale ambiri. M'mafakitale opanga magetsi, amagwiritsidwa ntchito kwambiri m'ma condenser ndi ma feedwater heaters. M'mafakitale opanga mafuta ndi mafakitale oyeretsera mafuta, amagwiritsidwa ntchito m'mafakitale osinthira kutentha omwe amasamutsa kutentha pakati pa mitsinje ya mankhwala.
Chifukwa machitidwe awa amagwira ntchito mosalekeza pansi pa mikhalidwe yovuta, kusankha njira yodalirikaWopanga chubu cha U bendndikofunikira kwambiri pakuonetsetsa kuti ntchito ikuyenda bwino komanso kukhala yotetezeka kwa nthawi yayitali.
Ndi chidziwitso chambiri pakupanga machubu achitsulo opanda msoko,Womic Steel imapereka machubu apamwamba kwambiri osinthira kutentha a U bend pamapulojekiti apadziko lonse lapansi aukadauloKampaniyo imapereka njira zosiyanasiyana zoyeretsera mapaipi kuphatikizapomachubu osinthira kutentha opanda msoko, machubu a boiler, machubu olondola okokedwa ozizira, ndi machubu opindika a U opangidwa mwamakonda.
Kudzera muukadaulo wapamwamba wopanga, njira zowongolera bwino khalidwe, ndi magulu opanga akatswiri,Womic Steel ikupitilizabe kuthandiza opanga zinthu zotenthetsera kutentha, malo opangira magetsi, ndi malo opangira mafuta ndi njira zodalirika zopachikira mapaipi padziko lonse lapansi..
