ASTM A210 Giredi C (ASME SA210 Giredi C) ndi chubu chachitsulo chopanda mpweya chapakati chomwe chimapangidwa makamaka kuti chigwiritsidwe ntchito popanga machubu a boiler ndi ma boiler flue, kuphatikizapo malekezero otetezera, makoma a uvuni ndi machubu othandizira, ndi machubu a superheater.
Giredi C ili ndi mphamvu zabwino zamakina, yokhala ndi mphamvu yokoka ya 485 MPa ndi mphamvu yotulutsa ya 275 MPa. Mphamvu izi, pamodzi ndi kapangidwe koyenera ka mankhwala, zimapangitsa machubu a ASTM A210 Giredi C kukhala oyenera kugwiritsidwa ntchito m'malo otentha kwambiri komanso opanikizika kwambiri komanso okhoza kupirira kupsinjika komwe kumachitika chifukwa cha ntchito ya boiler.
Machubu ayenera kupangidwa ndi njira yopanda msoko ndipo ayenera kumalizidwa ndi kutentha kapena kuzizira.
Pansipa pali tchati cha njira yopangira chitoliro chachitsulo chopanda msoko chomalizidwa mozizira:
Ndiye kodi pali kusiyana kotani pakati pa chitoliro chachitsulo chopanda msoko chomalizidwa ndi chotentha ndi chozizira ndipo mumasankha bwanji?
Yomalizidwa bwinoChitoliro chachitsulo chosasunthika ndi chitoliro chachitsulo chomwe chimakulungidwa kapena kubooledwa kutentha kwambiri ndi njira zina kenako nkuziziritsidwa mwachindunji kutentha kwa chipinda. Mapaipi achitsulo omwe ali mu mkhalidwe uwu nthawi zambiri amakhala olimba bwino komanso amphamvu pang'ono, koma mawonekedwe a pamwamba sangakhale abwino ngati mapaipi achitsulo omalizidwa ozizira chifukwa njira yochizira kutentha ingayambitse kukhuthala kapena kuchotsedwa kwa mpweya pamwamba pa chitoliro chachitsulo.
Yomalizidwa ndi oziziraChitoliro chachitsulo chopanda msoko chimatanthauza kukonza komaliza kwa chitoliro chachitsulo pogwiritsa ntchito kuzizira, kuzunguliza kozizira, ndi njira zina kutentha kwa chipinda. Chitoliro chachitsulo chomalizidwa ndi kuzizira chili ndi kulondola kwakukulu, komanso mawonekedwe abwino pamwamba, ndipo chifukwa kukonza kozizira kumatha kupititsa patsogolo mphamvu ndi kuuma kwa chitoliro chachitsulo, mphamvu zamakina za chitoliro chachitsulo chomalizidwa ndi kuzizira nthawi zambiri zimakhala zabwino kuposa za chitoliro chachitsulo chomalizidwa ndi kuzizira. Komabe, kuchuluka kwa kupsinjika kotsalira kungapangidwe mkati mwa chitoliro chachitsulo panthawi yogwira ntchito yozizira, zomwe ziyenera kuchotsedwa pochotsa kutentha pambuyo pake.
Chitoliro chachitsulo chomalizidwa ndi kutentha sichifuna kutentha.
Machubu omalizidwa kuzizira ayenera kuikidwa mu anneal wosafunikira kwambiri, kuikidwa mu anneal yonse, kapena kutenthedwa bwino pambuyo pa ntchito yomaliza yomaliza kuzizira.

Mayeso Ophwanyika
Kung'ambika kapena kusweka kumachitika nthawi ya 12 kapena 6 koloko pa chubu cha Giredi C chokhala ndi kukula kwa mainchesi 2.375 [60.3 mm] m'mimba mwake ndi yaying'ono siziyenera kuonedwa ngati maziko okanidwa.
Zofunikira zenizeni zitha kuwoneka muASTM A450, chinthu 19.

Zofunikira zenizeni zitha kuwoneka mu ASTM A450, chinthu 21.
Kuuma
Giredi C: 89 HRBW (Rockwell) kapena 179 HBW (Brinell).
Chitoliro chilichonse chachitsulo chiyenera kuyesedwa ndi mphamvu ya hydrostatic kapena kuyesa kwamagetsi kosawononga.
Zofunikira pa mayeso okhudzana ndi kupanikizika kwa hydrostatic zikugwirizana ndi ASTM 450, chinthu 24.
Zofunikira pakuyesera zamagetsi zosawononga zikugwirizana ndi ASTM 450, chinthu 26.
Ntchito zopangira machubu a boiler ndizofunikira kuti machubuwa akwaniritse zosowa za makina a boiler.
Akayikidwa mu boiler, machubu ayenera kuyima akukulirakulira komanso akuoneka ngati mikanda popanda kuwonetsa ming'alu kapena zolakwika. Akagwiritsidwa ntchito bwino, machubu a superheater ayenera kuyima onse opangira, kuwotcherera, ndi kupindika kofunikira kuti agwiritsidwe ntchito popanda kukhala ndi zolakwika.
Botop Steel ndi kampani yopanga mapaipi achitsulo cha kaboni yopangidwa ndi zitsulo zofewa komanso yogulitsa zinthu kuchokera ku China, komanso kampani yogulitsa mapaipi achitsulo chosasunthika, yomwe imakupatsani mapaipi achitsulo apamwamba, ofanana, komanso okwera mtengo.
Ngati mukufuna, chonde titumizireni uthenga, akatswiri, pa intaneti kuti mugwiritse ntchito!
