Womic Steel yakazvisimbisa semupi wezvinhu zvemhando yepamusoro uye mhinduro kwemakore makumi maviri. Nekuzvipira kwayo kuita zvakanaka, kambani iyi inoshanda kumaindasitiri akasiyana-siyana, ichipa mhinduro dzakagadzirirwa kuzadzisa zvinodiwa chaizvo. Zvinhu zvavo, zvinosanganisira zvinhu zvepamusoro zveASTM A335 P91 Type 2, zvinobva kuvagadziri vepasi rose vanotenderwa uye zvinogara zvichigadziriswa kuti zvisvike pazvinodiwa zvepamusoro. Womic Steel inonyanya kupa zvinhu zveP91 zvekushandisa zvine simba guru, kusanganisira mapaipi, zvigadziko, mavharuvhu, maflange, nezvimwewo, zvichiita kuti vatengi vagamuchire zvigadzirwa zvinoshanda zvakanaka.

Zvinhu Zvikuru zveASTM A335 P91 Type 2 tubes
ASTM A335 P91 Type 2 isimbi ye chrome-moly alloy inozivikanwa nesimba rayo rakasiyana, kuramba kupisa, uye simba rekukwira. Inorongwa sesimbi ye creep strength-enhanced ferritic (CSEF), zvichiita kuti ive yakakodzera kushandiswa pakupisa kwakanyanya uye pakumanikidzwa kwakanyanya. Chinhu ichi chinoitwa nenzira chaiyo yekurapa kupisa:

Kugara zvakanaka pa1050 °C.

Kutonhodza kwemhepo kusvika 200 °C.

Kupisa pa760 °C.

Maitiro aya anowedzera simba rayo rekufamba kwenguva refu uye kugara kwenguva refu, zvichiita kuti ive sarudzo yakanaka kune nzvimbo dzinoda kushanda nesimba.

Kuumbwa uye Mabhenefiti eASTM A335 P91 Steel Tubes
Chromium (9%): Inowedzera simba rekupisa kwakanyanya, kuramba oxidation, uye hunhu hwemakanika.

Molybdenum (1%): Inovandudza kutwasuka, kuramba kupera, uye simba rekukwira kana kutonhora zvakanyanya.

Vanadium neColumbium/Niobium: Zvinowedzera simba rekufamba-famba uye kuramba kupisa.

Mabhenefiti eASTM A335 P91 Steel Tubes
Ukobvu hwemadziro hwakaderera: Zvinobvumira zvikamu zvakareruka, nguva shoma yekuwedera, uye simbi shoma yekuzadza.

Kugara kwenguva refu kwekuneta kwekupisa: Zviri nani kagumi kupfuura zvakamboitika kare zvakaita seT22 kana P22.

Kuwedzerwa kwekupisa kwekushanda: Kunovandudza kushanda zvakanaka mukushandiswa kwekupisa kwakanyanya.

Mashandisirwo eASTM A335 P91 Steel Tubes
P91 inoshandiswa zvakanyanya mumaindasitiri anoda zvinhu zvinokwanisa kutsungirira kupisa kwakanyanya uye kumanikidzwa. Mashandisirwo akajairika anosanganisira:

Kugadzira magetsi: Maboiler, mitsetse yekudziisazve, uye mafekitori emagetsi akabatanidzwa.

Mafekitori emafuta: Mahita, michina yekugadzirisa gasi, uye mabasa emunzvimbo dzinopisa mafuta.

Masisitimu emapaipi anodziya zvakanyanya: Akakodzera kukotama, kuputira, uye kupinza.

Kuumbwa kweMakemikoro eASTM A335 P91 Steel Tubes
Kuumbwa kwemakemikari eP91 kunovimbisa kushanda kwayo kwepamusoro:

Kabhoni: 0.08% - 0.12%

Manganese: 0.30% - 0.60%

Chromium: 8.00% - 9.50%

Molybdenum: 0.85% - 1.05%

Vanadium: 0.18% - 0.25%

Nitrogen: 0.030% - 0.070%

Zvimwe zvinhu: Nickel, aruminiyamu, columbium, titanium, uye zirconium muhuwandu hwakarongwa.

Zvivakwa zveMichina
Simba reKubata: Zvishoma 85,000 PSI (585 MPa).

Simba reGoho: Zvishoma 60,000 PSI (415 MPa).

Kushongedza uye Kupisa Machubhu eSimbi eASTM A335 P91
Kushongedza P91 kunoda kutevedzera zvakanyanya maitiro ekuchengetedza hunhu hwayo:

Kupisa: Zvakakosha kudzivirira kutsemuka kunokonzerwa nehydrogen.

Kudzora tembiricha pakati pemagetsi: Kunochengetedzwa uchishandisa masisitimu emazuva ano ekudziyisa einduction.

Kurapa kupisa mushure mekuweld (PWHT): Zvakakosha kuti pave nechimiro chakanaka uye kudzivirira kutadza kushanda.

Maelectrode ekuwelda: Anofanira kuenderana nechimiro chechinhu chikuru.

Sei Uchifanira Kusarudza Machubhu Esimbi eWomic Steel ASTM A335 P91?
Zvinhu zvakawanda: Zvinhu zveP91 zvemhando yepamusoro zvinoenderana nezvaunoda.

Hunyanzvi: Chikwata chine ruzivo chinokutungamira pakusarudza zvinhu uye mashandisirwo azvo.

Kuzvipira kune mhando: Zvinhu zvakanakisisa chete zvinobva kuvagadziri vanotenderwa.

Kuti muwane zvese zvinodiwa neASTM A335 P91 Type 2, taurai neWomic Steel nhasi. Chikwata chavo chakagadzirira kupa mhinduro dzinopfuura zvamunotarisira uye dzinopa zvinhu zvemhando yepamusoro zvemapurojekiti enyu.
