ASTM B88 C12200 Mtundu wa Chitoliro Cholimba cha Mkuwa L - Tsamba Lachidziwitso Chaukadaulo

1. Chidule cha Zamalonda

Womic Steel ndi kampani yodalirika yopanga mapaipi apamwamba kwambiri a mkuwa omwe ali ndi zinthu zofanana ndiASTM B88miyezo, makamakaMtundu Lzofunikira zopangidwa kuchokeraC12200 (phosphorous-deoxidized, phosphorous yotsala yambiri)mkuwa. Mapaipi olimba a mkuwa awa amagwiritsidwa ntchito kwambirimapaipi, HVAC, chitetezo cha moto, gasi, ndi makina ogwiritsira ntchito magetsichifukwa cha kukana dzimbiri, kulimba, komanso kupangika bwino.
Mkuwa wa C12200 uli ndi mkuwa wochuluka komanso phosphorous yochepa, zomwe zimapangitsa kuti ukhale wogwirizana komanso kuti usawonongeke ndi hydrogen. Mapaipi a Type L ali ndi mulingo woyenera pakati pa makulidwe ndi kulemera kwa khoma, zomwe zimapangitsa kuti zikhale zodalirika pakupanga pamwamba pa nthaka komanso pansi pa nthaka.

2. Mitundu Yopangira

  • Chidutswa cha Kunja (OD):6 mm mpaka 219 mm
  • Kulemera kwa Khoma (WT):0.3 mm mpaka 10 mm
  • Utali:Kutalika kwanthawi zonse kwa3m, 5m, 6mndikutalika kosinthidwa komwe kulipo mukapempha
  • Machubu Ozungulira:Ikupezeka muMa coil a 25m kapena 50mkuti muyike mosavuta mu zosinthira kutentha
  • Mapeto Omaliza:Mapeto osavuta, oyeretsedwa komanso ochotsedwa; amapezeka ndi zipewa kapena opanda

3. Kulekerera kwa Miyeso (Machubu a Mkuwa a ASTM B88 C12200)

Womic Steel imatsimikizira kulondola kolondola kwa miyeso yaC12200machubu ogwirizana ndiASTM B88miyezo. Kulekerera kumeneku kumagwira ntchito:

A. Chiyerekezo chapakati cha m'mimba mwake wakunja kwa chubu ndi chiyerekezo cha m'mimba mwake wapamwamba kwambiri komanso wocheperako wakunja, monga momwe zimakhalira pa gawo lililonse la chubu.

B Kupatuka kwakukulu pa mfundo imodzi.

C imasonyeza kuti zinthuzo sizipezeka kawirikawiri kapena kuti palibe kulekerera komwe kwakhazikitsidwa

Kulekerera kumeneku kumatsimikizira kuti machubu amakumanazofunikira kwambiri komanso zapamwamba, kuwapangitsa kukhala oyenerantchito zovuta zamafakitale ndi zam'madzi.

3. Kapangidwe ka Mankhwala (C12200 - ASTM B88)

Chinthu             Kapangidwe (% potengera kulemera)

Mkuwa (Cu)MinB≥ 99.9 (kuphatikiza siliva)

Phosphorus (P) 0.015 – 0.040

Mpweya wa okosijeni uyenera kukhala 10 ppm max.

8. Kusankha zitsanzo

Kuyesa ndi kusanthula kumachitika motsatira ASTM B88 ndi njira zamkati za QA. Zitsanzo zoyesera zimasankhidwa mwachisawawa kuchokera ku gulu lililonse la:

l Mankhwala okhutira

l Katundu wa makina

l Kulondola kwa miyeso

l Mkhalidwe wa pamwamba

9. Kulongedza

Kuonetsetsa kutikusamalira ndi mayendedwe otetezeka, Womic Steel imaperekamayankho olimba olongedza, kuphatikizapo:

  • Chophimba Choletsa Kutulutsa Ma Oxidation:Choteteza chomwe chimagwiritsidwa ntchito popewa dzimbiri panthawi yosungira ndi poyendera
  • Mapeto a Zipewa:Zipewa zapulasitiki kapena zachitsulo zomwe zili kumapeto kwa machubu kuti zisaipitse
  • Kusonkhanitsa:Chingwe cholimba ndi mikanda ya pulasitiki kapena yachitsulo kuti chikhale cholimba
  • Chikwama cha Matabwa:Yodzaza mkatimabokosi amatabwa osanyowayokhala ndi thovu loteteza

11. Ubwino Wosankha Chitsulo cha Womic

12. Mapulogalamu

ZathuASTM B88 C12200Machubu ndi abwino kwambiri pa:

  • Makampani Ogulitsa Zam'madzi: Zoziziritsira madzi a m'nyanja, mapaipi, ndi zosinthira kutentha kwa sitima
  • Malo Opangira Mphamvu:Zokondetsa nthunzi ndimakina ozizira
  • Zomera Zochotsa Mchere M'madzi:Mapaipi osapsa ndi dzimbiri omwe amagwiritsidwa ntchito m'madzi amchere
  • Kukonza Mankhwala:Machubu osinthira kutentha omwe amatentha kwambiri komanso othamanga kwambiri
  • HVAC & Firiji: Ma coil oziziritsira mpweya ndi makina oziziritsira mafakitale

Mapeto

Mapaipi amkuwa a Womic Steel a ASTM B88 C12200 Type L amapereka magwiridwe antchito abwino kwambiri, kulimba, komanso kukana dzimbiri, zomwe zimapangitsa kuti akhale chisankho chabwino kwambiri pamakina osiyanasiyana a mapaipi. Potsatira kwambiri miyezo ya ASTM komanso chitsimikizo chokwanira cha khalidwe, timaonetsetsa kuti kutumiza kulikonse kukukwaniritsa ziyembekezo zapamwamba kwambiri pakugwira ntchito bwino komanso kudalirika.

Timadzitamandira ndintchito zosintha mwamakonda, kupanga mwachangundinetiweki yotumizira padziko lonse lapansi, kuonetsetsa kuti zosowa zanu zikukwaniritsidwa molondola komanso mwaluso.
