A335 P92(inoenderana neChinese standard grade 10Cr9MoW2VNbBN) isimbi yechizvarwa chinotevera inodzivirira kupisa yakagadzirwa kubva kuP91Nekuwedzera tungsten (W) ku9% chromium steel uye kuwedzera molybdenum yakaenzana (Mo+0.5W) kubva pa1% muP91 kusvika pa1.5%, mashandiro echinhu ichi pakupisa kwakanyanya akawedzerwa zvakanyanya.

Nzvimbo huru dzekushandisa dzinosanganisira:

Kugadzira Simba rekupisa rinopisa zvakanyanya: P92 ndiyo chinhu chikuru chekushandisa mapaipi makuru emhepo uye kudzoreredza kupisa mapaipi emhepo muzvikamu zve1000MW zvemhando yepamusoro-soro, nekupisa kwakanyanya kwekushanda kwe625.°C. Pa600°C, dhizaini inobvumidzwa yekumanikidzwa inosvika 128MPa, uye simba rekukwira rinokwira zvakanyanya≥100MPa. Simba rayo rekupwanya kuputika kwemvura inokwira nekudziya kwakanyanya rakakwirira ne30% kupfuura P91, uye mudziyo wemamiriyoni ekilowatt unodya matani anosvika 800.

Zvikamu Zvikuru zveBoiler: Zvinoshandiswa zvakanyanya mumaboiler headers, masuperheaters, mareheaters, nezvimwe zvikamu zvekumanikidza. Ndiyo imwe yemhando dzesimbi dzinofarirwa pakugadzira michina mikuru yemagetsi inodziya mukati menyika nekunze kwenyika.

Indasitiri yePetrochemical: Inoshandiswa mumapaipi ehydrogenation reactor, machubhu efurnace anotsemuka, uye mamwe masisitimu anodziya zvakanyanya uye ane kumanikidzwa kwakanyanya.

Simba reNyukireya: Rinoshandiswawo mumapombi echipiri emagetsi enyukireya echizvarwa chechitatu akadai seAP1000.

Zvichienzaniswa nesimbi dzisina ngura dzinoshandiswa ne austenitic, P92 ine zvakanakira zvinosanganisira kuramba ngura zvakasimba, kupisa kwakanyanya, uye kuwedzera kwekushisa kwakaderera.

II. Zvigayo zveSimbi zveMumba zvine Mabhenefiti Ekukwikwidzana

Kugadzirwa kwesimbi yeP92 kwakaoma, kunoda mwero wepamusoro mukugadzira maitiro uye kudzora kugadzirwa. Parizvino, huwandu hushoma hwemichina yesimbi yemumba ndiyo yakawana kugona kwakasimba kwekugadzira.

1. Beizhong Group—Mutungamiriri weMugove weMusika

Beizhong Group ine musika unodarika 80% muchikamu chemapombi esimbi eP92 emuno. Zvigadzirwa zvayo zvinopfuura zviratidzo zvekuongorora makumi maviri nemasere, uye kubudirira kwayo kwetekinoroji kwakahwina Mubairo wekutanga weChina Electric Power Science and Technology Innovation. Boka iri rakawana mukana wekupinda mumusika kubva kuΦ89 kusvikaΦ813, ine ruzivo rwakakura rweinjiniya mukupa mapaipi mana makuru ezvikamu zvakakosha zvikuru.

2. Yonggang Group—Mabhenefiti mukugadzirwa kweBillet

Yonggang Group yakaedza kugadzira SA335 P92 muna 2017 uye ikozvino ine simba rekugadzira mabheti anotenderera anogadzirwa netambo dzakasiyana siyana kubva paφ380mm kusvikaφ800mm, zvichipa mukana wekukwikwidzana mumusika webillet hombe wemuno. P91, P92, nezvimwe zvigadzirwa zvebillet hombe zvine alloy zvine chinzvimbo chepamusoro mumusika muChina. Pamusoro pezvo, yakasarudzwa sefekitori yekuratidzira kugadzira zvinhu zvine hungwaru munyika, ichiramba ichivandudza kudzora mhando yezvigadzirwa uye kugadzirisa mitengo.

3. Hebei Hongrun Midziyo yeNyukireya—Midziyo Yakasiyana uye Maitiro

Hongrun Nuclear Equipment inoshandisa muchina wekuwedzera simba rematani 50,000 kugadzira mapaipi esimbi asina musono ane dhayamita hombe eP92. Ichishanda pamwe chete neBaowu Special Steel, inoshandisa ma ingts esimbi emhando yepamusoro, zvichikonzera zvigadzirwa zvine chimiro chakakora uye mashandiro akanaka kwazvo. Mapaipi ayo esimbi eP92 apasiswa chitupa chechigadzirwa neNational Power Equipment Center, uye zviratidzo zvese zvekushanda zvinosangana nezvinodiwa zveGB/T 5310 uye ASME SA335.

4. Vamwe Vagadziri

Baosteel Special Steel, Tianguan Group, Xinxing Ductile Iron, nedzimwe makambani dzakawanawo vimbiso yekugadzirwa kwezvinhu zvine chekuita neP92, zvichikurudzira maitiro enzvimbo yezvinhu izvi.

III. Zvakanakira Kukwikwidzana Zvakakwana

Zvakanakira zvemakambani esimbi emuno muzvigadzirwa zveP92 zvinonyanya kuratidzwa mu: chekutanga, kuderedzwa kwakanyanya kwemitengo yekutenga kuburikidza nekutsiviwa kwekutenga zvinhu kubva kunze kwenyika; chechipiri, kugadzikana kwemhando yezvigadzirwa kwakawedzerwa nekuda kwekushanduka kwakangwara uye kwedhijitari (semuenzaniso, chirongwa cheYonggang chefekitori yakangwara chakawana kuwedzera kwekubudirira kwekugadzira ne12% uye kudzikiswa kwe15.7% kwehuwandu hwekukanganisa); uye chechitatu, kufambira mberi kuri kuramba kuchienderera mberi muzvinhu zvepamusoro-soro zvakaita semapaipi makuru nemadziro akakora, zvichideredza zvishoma nezvishoma kuvimba nezvinhu zvinobva kunze kwenyika.
