Kuyerekeza Pakati pa Mapaipi a Chitsulo Chosapanga Dzimbiri a 304H ndi 304
— Mphamvu Zopangira ndi Mayankho a Zogulitsa za Womic Steel
1. Chidule cha Zamalonda
Womic Steel ndi kampani yotsogola yopanga mapaipi achitsulo chosapanga dzimbiri chapamwamba kwambiri, yomwe imapereka zonse ziwiri304Hndi304mapaipi achitsulo chosapanga dzimbiri mogwirizana ndi miyezo yayikulu yapadziko lonse lapansi, kuphatikizapo:
lASTM A312/A213/A269/A358
lASME SA312 / SA213
lEN 10216-5 / EN 10297-2
lJIS G3459 / ISO 9329-4
lGB/T 14976 / GB/T 13296
304H ndi 304 zonse ndi zitsulo zosapanga dzimbiri za austenitic, koma zimapangidwa kuti zigwire ntchito bwino m'malo osiyanasiyana—304H imagwira ntchito bwino kwambiri pa kutentha kwambiri, pamene304 imapereka kukana dzimbiri komanso kusinthasintha kwabwinomu ntchito zonse zofunika.

Thekuchuluka kwa kabonimu 304H kumawonjezera mpweya wa carbide (Cr₂₃C₆), kumawonjezerakukana kukwawa ndi mphamvu yotentha kwambiriKuchuluka kwa mpweya wochepa wa .304 ndikwabwino kwambirinyumba zolungidwazimafuna kukana dzimbiri pakati pa tinthu tating'onoting'ono.
3. Kukula ndi Mitundu ya Zogulitsa
Womic Steel imapereka mapaipi osiyanasiyana achitsulo chosapanga dzimbiri opangidwa kuti agwiritsidwe ntchito m'mafakitale, zomangamanga, komanso kukakamiza:
Mapaipi Opanda Msoko:
Chipinda chakunja: 6mm - 610mm
Kulemera kwa khoma: 0.5mm - 50mm
Mapaipi otsekemera (RW / TIG / Laser):
Chipinda chakunja: 8mm – 1219mm
Kulemera kwa khoma: 0.5mm - 30mm
Zosankha Zina:
Machubu osinthira kutentha, machubu opindika a U, machubu opukutidwa, ndi mapaipi opangidwa mwamakonda.
Kutalika: Kutalika kokhazikika kapena mpaka mamita 18
Zomaliza Pamwamba: Zophikidwa, zophikidwa, zopukutidwa, zopukutidwa
4. Katundu wa Makina
| Katundu | 304 Chitsulo Chosapanga Dzira | Chitsulo Chosapanga Dzira cha 304H |
| Mphamvu Yokoka (MPa) | ≥ 515 | ≥ 590 |
| Mphamvu Yotulutsa 0.2% (MPa) | ≥ 205 | ≥ 235 |
| Kutalika (%) | ≥35 | ≥ 35 |
| Kuuma (HBW) | ≤192 | ≤192 |
| Mphamvu Yopasuka ya Kuyenda (650℃, maola 100,000) | ~55 MPa | ~80 MPa |
Chidziwitso Chofunika:
304H imagwira ntchito bwino kuposa 304 chifukwa cha kutentha kwa nthawi yayitali (kupitirira 550℃), zomwe zimapangitsa kuti ikhale yabwino kwambirizotenthetsera magetsi, opanga mafuta, ndi makina opangira kutentha.
5. Zofunikira pa Kutentha ndi Kuwotcherera
| Chizindikiro | 304 | 304H |
| Kusakaniza kwa Yankho | 1010 – 1065℃ | ≥ 1080℃ |
| Kuyankha kwa Ntchito Yozizira | Zabwino kwambiri | Kuchuluka kwa ntchito yolimba |
| Kutha kupotoka | Zabwino kwambiri | Amafuna zitsulo zambiri zodzaza kaboni |
| Chithandizo cha Kutentha Pambuyo pa Kuwotcherera | Zosankha | Akulimbikitsidwa pa mafupa ofunikira |
Malangizo Owotcherera: Pa 304H, Womic Steel ikupereka lingaliroWaya wowotcherera wa ER308H, ndi njira yowongolera kutentha bwino komanso kupopera pambuyo pa weld kuti zigwirizane bwino kwambiri m'mapaipi okhala ndi mphamvu zambiri.
6. Kuyerekeza Kukana Kudzimbiri
M'malo okhala ndi chloride,304 ili ndi kukana kwakukulu kwa maenje.
Mphamvu ya 304H yopezera maenje ndi pafupifupi50mV yotsika, zomwe zinapangitsa kuti pakhale kuukira koyambirira komwe kunachitika m'deralo.
| Mkhalidwe Woyesera | 304 | 304H |
| Kuchuluka kwa Cl⁻ 180ppm, zaka 2 | Palibe kutayikira | Kuboola kwawonedwa |
| Chiwopsezo cha dzimbiri pachaka (mm/chaka) | ~0.015 mm/chaka | ~0.020 mm/chaka |
Gwiritsani ntchito304m'malo omwe amafuna kukana dzimbiri bwino komanso m'malo osiyanasiyana mongamakina oziziritsira m'madzi, kukonza chakudyakapenamatanki a mankhwala.
7. Kuyesa ndi Chitsimikizo cha Ubwino
Womic Steel akuchitakuwunika kwabwino konsendipo amatsatira njira zokhwima za QA/QC:

Mapaipi onse akhoza kuperekedwa ndi:
EN 10204 3.1 / 3.2 Chitsimikizo
Kuvomerezeka kwa ISO 9001, PED, SGS, TUV, BV
8. Ubwino Wonyamula ndi Kunyamula
Kupaka Kwachizolowezi:
Mipando ya hexagonal yokhala ndi zipewa zomaliza, zokutira pulasitiki, nsalu yosalowa madzi, mabokosi amatabwa, kapena zoyikamo zitsulo.
Zolemba:
Chitoliro chilichonse chilichojambulidwa ndi laserndi nambala ya kutentha, mtundu wa zinthu, kukula, ndi chizindikiro cha Womic Steel. Chizindikiro chapadera kapena kutsata kwa QR komwe mungasankhe.
Kayendetsedwe ka zinthu:
Womic Steel imagwirizana mwachindunji ndi mizere yotumizira katundu ndi zotumiza katundu. Ubwino waukulu paAsia-South America, Middle East, ndi Southeast Asianjira zotumizira mwachangu za FOB/CIF/DDP.
9. Ntchito Zokonza ndi Kukonza Malo Ozungulira
lKudula, kugwetsa, kupindika, kupendeketsa
lKupukuta (Ra < 0.4μm yogwiritsidwa ntchito poyesa zakudya)
lZigawo Zofananira: Zigongono, ma tee, ma flange, ma valve
Womic Steel imaperekansontchito zopangira zinthu zisanapangidweza ma modular payipi association.
10. Mphamvu Yopangira ndi Nthawi Yotsogolera
Kupanga Kwapachaka:Matani 30,000+
Mizere Yopangira:
Mabenchi 24 Ozizira Ojambula
Mizere 10 Yowotcherera Yokha

Nthawi yoperekera:
Masiku 15 - 25 ogwira ntchito pa maoda wamba; kutumiza mwachangu kulipo m'masiku 7 pa ntchito zachangu.
11.Zochitika Zogwiritsira Ntchito ndi Buku Lotsogolera Kusankha Zinthu
| Malo Ofunsira | Giredi Yovomerezeka | Kulungamitsa |
| Zipangizo za kukhitchini, zida zachipatala, nyumba zomangira makoma | 304 | Kukana dzimbiri bwino komanso kupangika bwino |
| Machubu a ng'anjo ya petrochemical, ma roller othandizira kutentha, zotenthetsera za boiler yamagetsi | 304H | Mphamvu yapamwamba kwambiri komanso kukana kukwawa |
12. N’chifukwa Chiyani Muyenera Kusankha Chitsulo cha Womic?
lKupereka Zinthu Zosaphika Zokhazikika: Mgwirizano wanzeru ndi Baosteel, TISCO, ndi Zhangpu ukuonetsetsa kuti zinthu zikuyenda bwino
lUkadaulo Wapamwamba: Kuphimba mkati mwa nyumba, NDT ya pa intaneti, kulamulira kozungulira kokha
lKusintha Kosinthika: OD yayikulu, khoma lokhuthala, mapaipi ooneka ngati mawonekedwe, ndi MOQ yochepa yovomerezeka
lZochitika Padziko Lonse la Ntchito: Yoperekedwa ku Codelco Chile, Total, Qatar Energy, Malaysian Petrochem, ndi zina zambiri
Kuti mudziwe zambiri zokhudza ukadaulo, mitengo, kapena upangiri wa polojekiti, chonde lemberaniGulu Logulitsa Padziko Lonse la Womic Steel — mnzanu wodalirika wa chitsulo chosapanga dzimbiri.
