ASTM A210 Gulu C (ASME SA210 Grade C) ndi chubu chachitsulo chosakanizidwa ndi mpweya wapakatikati chomwe chimapangidwira kuti chigwiritsidwe ntchito popanga machubu otenthetsera ndi zitoliro zowotchera, kuphatikiza malekezero achitetezo, khoma la ng'anjo ndi machubu othandizira, ndi machubu otenthetsera kwambiri.
Kalasi C ili ndi mphamvu zamakina abwino, zokhala ndi mphamvu zolimba za 485 MPa ndi mphamvu zokolola za 275 MPa. Zinthuzi, pamodzi ndi mankhwala oyenera, zimapanga machubu a ASTM A210 Grade C oyenerera kuti agwiritsidwe ntchito pa kutentha kwambiri komanso malo oponderezedwa komanso okhoza kulimbana ndi zovuta zomwe zimapangidwa ndi ntchito ya boiler.
Machubu ayenera kupangidwa ndi njira yopanda msoko ndipo azikhala otentha kapena ozizira.
Pansipa pali tchati chotsatira cha njira yopangira chitoliro chozizira chosamalitsa chopanda chitsulo:
Ndiye pali kusiyana kotani pakati pa chitoliro chachitsulo chosasunthika komanso chozizira komanso chomwe mumasankha?
Kutentha-kuthaSeamless zitsulo chitoliro ndi zitsulo chitoliro kuti adagulung'undisa kapena kulasidwa pa kutentha kwambiri ndi njira zina ndiyeno utakhazikika mwachindunji firiji.Mapaipi achitsulo m'chigawo chino nthawi zambiri amakhala ndi kulimba kwabwinoko komanso mphamvu zina, koma mawonekedwe apamwamba sangakhale abwino ngati mapaipi achitsulo otha kuzizira chifukwa njira yochizira kutentha imatha kudzetsa makutidwe ndi okosijeni kapena kutulutsa mpweya pamwamba pa chitoliro chachitsulo.
Kuzizira-kumalizaMsoko zitsulo chitoliro amatanthauza processing yomaliza ya chitoliro zitsulo ndi kujambula ozizira, ozizira anagubuduza, ndi njira zina kutentha firiji.Chitoliro chachitsulo chozizira chozizira chimakhala cholondola kwambiri, komanso khalidwe labwino, ndipo chifukwa kuzizira kungathe kulimbitsa mphamvu ndi kuuma kwa chitoliro chachitsulo, makina a chitoliro chachitsulo chozizira nthawi zambiri amakhala abwino kuposa chitoliro chachitsulo chotentha. .Komabe, kupsinjika kwina kotsalira kungapangidwe mkati mwa chitoliro chachitsulo panthawi yozizira, yomwe iyenera kuthetsedwa ndi chithandizo cha kutentha chotsatira.
Chitoliro chachitsulo chotentha chotentha sichifuna chithandizo cha kutentha.
Machubu oziziritsa aziziziritsidwa, otsekedwa kwathunthu, kapena kutentha kwanthawi zonse pambuyo pomaliza kuzizira.

Mayeso a Flattening
Misozi kapena kusweka kumachitika pa malo a 12 oг 6 koloko pamachubu a Grade C okhala ndi kukula kwa 2.375 mkati.
Zofunikira zenizeni zitha kuwonedwa muChithunzi cha ASTM A450, gawo 19.
Kuyesa kwa Flaring
Zofunikira zenizeni zitha kuwonedwa mu ASTM A450, chinthu 21.
Kuuma
Kalasi C: 89 HRBW (Rockwell) kapena 179 HBW (Brinell).
Chitoliro chilichonse chachitsulo chiyenera kuyesedwa ndi hydrostatic pressure test kapena magetsi osawononga.
Zofunikira zoyeserera zokhudzana ndi kupanikizika kwa Hydrostatic ndizogwirizana ndi ASTM 450, chinthu 24.
Zofunikira pakuyesa kosawonongeka kwamagetsi ndizogwirizana ndi ASTM 450, chinthu 26.
Kupanga ntchito ndikofunikira kuti machubu a boiler awonetsetse kuti machubu akukwaniritsa zofunikira za boiler.
Akalowetsedwa mu boiler, machubu aziyima akukulirakulira ndi mikanda popanda kuwonetsa ming'alu kapena zolakwika.Akagwiritsidwa ntchito bwino, machubu otenthetsera moto amatha kukhazikika.kuwotcherera.ndi kupindika ntchito zofunikira kuti zigwiritsidwe ntchito popanda zovuta.
Botop Zitsulo ndi wopangidwa mwapamwamba kwambiri wopangira chitoliro cha chitsulo cha carbon steel ndi ogulitsa kuchokera ku China, komanso chitoliro chachitsulo chosasunthika, chomwe chimakupatsirani chitoliro chachitsulo chapamwamba, chokhazikika, komanso chamtengo wampikisano.
Ngati mukufuna, chonde tilankhule nafe, akatswiri, pa intaneti pa ntchito yanu!
