Wopanga Mapaipi Achitsulo Otsogola & Wopereka Ku China |

Boiler yachitsulo ya ASTM A210 ndi Superheater Tube

ASTM A210 chubu lachitsulo ndi chubu chachitsulo chapakati cha carbon seamless steel chomwe chimagwiritsidwa ntchito ngati ma boiler ndi machubu otenthetsera kutentha kwambiri komanso malo opanikizika kwambiri, monga m'malo opangira magetsi ndi ma boiler a mafakitale.

Astm A210 boiler zitsulo chitoliro

Akunja Diameter: 1/2mu(12.7mm)≤ OD ≤5in (127mm)

Makulidwe a Khoma: 0.035 mu (0.9mm)≤ WT ≤0.500 mu (12.7mm)

Machubu okhala ndi miyeso ina atha kuperekedwa, malinga ngati machubu oterowo atsatira zofunikira zina zamtunduwu.

Zida zogwiritsira ntchito

Zochita Zopanga Zitsulo--Chitsulocho chidzaphedwa.

chitsulo chophedwa chimatanthawuza kuwonjezera kwa zinthu zina za deoxidizers monga silicon, aluminiyamu, ndi manganese panthawi yosungunuka chitsulo.

Zowonjezerazi zimatha kuchitapo kanthu ndi okosijeni muzitsulo kuti apange ma oxide olimba, motero amachepetsa mpweya wa okosijeni muzitsulo ndikuletsa mapangidwe a oxidizing inclusions.

Gawo la ASTM A210

ASTM A210 imapezeka m'makalasi awiri:Giredi A-1 ndi Grade C.

ASTM A210 Seamless Steel Tube Production Njira

Mapaipi achitsulo adzapangidwa ndi njira yopanda msoko ndipo azikhalakutentha-kutha or ozizira-wamalizamonga tafotokozera.

Nthawi zambiri, mapaipi achitsulo okhala ndi m'mimba mwake kuposa mamilimita 30 amakhala otentha ndipo omwe ali ndi mainchesi osakwana kapena ofanana ndi mamilimita 30 amatha kuzizira.Njira yosiyanitsira iyi siili yeniyeni koma ingagwiritsidwe ntchito ngati njira yachangu komanso yosavuta yodziwira njira yopangira chitoliro chachitsulo chosasunthika.

Kutentha Chithandizo

Chithandizo cha kutentha sikofunikira pamachubu omaliza otentha.

Machubu oziziritsa oziziritsa adzapatsidwa anneal yocheperako, anneal yathunthu, kapena kutentha kwanthawi zonse pambuyo pomaliza kuzizira komaliza.

Zofunikira zamagulu awa zimatsimikizira kuti machubu ali ndi mphamvu zokwanira komanso kukana kutentha.

Gulu 4 limapereka ziwerengero zocheperako zowerengeka pa chilichonse1/32mkati [0.8 mm] kuchepa mu makulidwe a khoma.

Kumene makulidwe a khoma ali pakati pa zinthu ziwiri zomwe zasonyezedwa pamwambapa, mtengo wocheperako wotalikirapo udzatsimikiziridwa ndi equation yotsatirayi:

Magawo a Imperial (mu): E = 48t+15.00

SI unit(mm): E = 1.87t+15.00

kumene:

E = elongation mu 2 in. kapena 50 mm, %,

t = makulidwe enieni a chitsanzo.

Mayeso Olimba

Mayeso a kuuma kwa Brinell kapena Rockwell apangidwa pazitsanzo zamachubu awiri kuchokera pagawo lililonse.

ASTM A210 Gulu A-1:79-143 HBW

ASTM A210 Gulu C: 89-179 HBW

HBW imatanthawuza kuyeza kwa Brinell Hardness, pomwe "W" imayimira kugwiritsa ntchito mpira wa carbide ngati chowongolera.

Kuyesera kwina

Kumaliza Pamwamba

Ikhoza kuzifutsa kapena kuphulika, kapena zonse ziwiri, ndipo gawo ili ndilogwirizana, ndipo chisankhocho chimachokera pa mgwirizano pakati pa wogwiritsa ntchito ndi wopanga.

Pickling makamaka ntchito kuchotsa oxidized zigawo ndi zonyansa zina pamwamba pa mipope zitsulo.

Kuwombera kumagwiritsidwa ntchito kuyeretsa pamwamba ndikuwonjezera mphamvu zake zomatira.

Mankhwalawa samangokhudza khalidwe lapamwamba la chitoliro komanso angakhudze ntchito yake yomaliza.

Kupanga Zochita

Akalowetsedwa mu boiler, machubu aziyima akukulirakulira ndi mikanda popanda kuwonetsa ming'alu kapena zolakwika.Akagwiritsidwa ntchito moyenera, machubu otenthetsera moto amatha kuyimilira ntchito zonse zopangira, kuwotcherera, ndi kupindika kofunikira kuti agwiritse ntchito popanda kuwonongeka.

Chizindikiro cha ASTM A210

Zotsatirazi ziyenera kuzindikirika bwino:

Dzina la wopanga kapena logo.

Kufotokozera kwa chitoliro (kukula, makulidwe a khoma, etc.).

Chitoliro cha chitoliro.

Mtundu wa kupanga chitoliro chachitsulo: kutentha komaliza kapena kuzizira komaliza.

Mapulogalamu a ASTM A210

Amagwiritsidwa ntchito popanga ma boiler ang'onoang'ono mpaka apakatikati amphamvu yocheperako, monga ma boiler oyimilira, ma boilers okhala pansi, ndi ma boiler ena omwe amagwiritsidwa ntchito potenthetsera mafakitale kapena nyumba.

Ma superheaters ndi mbali za boiler yomwe imagwiritsidwa ntchito kukweza kutentha kwa nthunzi pamwamba pa kuwira kwake, ndipo machubu a ASTM A210 ndi oyenera kupanga zigawo zotentha kwambirizi.

Zathu Zogwirizana

Ndife apamwamba welded mpweya zitsulo chitoliro wopanga ndi katundu kuchokera China, komanso msokonezo zitsulo chitoliro stockist, kukupatsani osiyanasiyana zitsulo chitoliro njira!
