Zvinhu zvakakosha zveASTM A335 P91 Type 2 machubhu
ASTM A335 P91 Type 2 ndeye chrome-moly alloy simbi inozivikanwa nekusimba kwayo, kusamira kwekushisa, uye simba rekukambaira. Inotsanangurwa sesimbi inokambaira-inowedzeredzwa ferritic (CSEF) simbi, ichiita kuti ive yakakodzera kune yakakwirira-tembiricha uye yakanyanya-kudzvanywa maapplication. Izvo zvinhu zvinosangana neimwe nzira yekupisa kupisa:

Normalizing pa1050 °C.

Kutonhora kwemhepo kusvika ku200 ° C.

Kupisa pa760 ° C.

Iyi nzira inowedzera simba rayo rekukamba uye kusimba, zvichiita kuti ive sarudzo yepamusoro yenzvimbo dzinoda.

Kuumbwa uye Zvakanakira zveASTM A335 P91 Steel Tubes
Chromium (9%): Inosimudzira kusimba kwepamusoro-tembiricha, oxidation kuramba, uye michina zvinhu.

Molybdenum (1%): Inovandudza elasticity, kupfeka kuramba, uye yakakwirira-tembiricha inokambaira simba.

Vanadium uye Columbium / Niobium: Kuwedzera kuwedzera simba rekukwira uye kupisa kwekuneta kuramba.

Zvakanakira zveASTM A335 P91 Steel Tubes
Yakaderedzwa madziro ukobvu: Inobvumira zvinhu zvakareruka, yakaderedzwa nguva yewelding, uye shoma yekuzadza simbi.

Hupenyu hwekuneta kwepamusoro: Kusvika kagumi zvirinani pane zvakafanotangira seT22 kana P22.

Kuwedzera tembiricha yekushanda: Inovandudza mashandiro mune yakakwirira-tembiricha maapplication.

Zvikumbiro zveASTM A335 P91 Steel Tubes
P91 inoshandiswa zvakanyanya mumaindasitiri anoda zvinhu zvinokwanisa kutsungirira tembiricha yakanyanyisa uye kumanikidza. Zvishandiso zvakajairika zvinosanganisira:

Kugadzira magetsi: Maboiler, mitsara yekupisa, uye zvidyarwa zvakasanganiswa.

Petrochemical zvidyarwa: Heaters, gasi kugadzirisa michina, uye oirifield masevhisi.

Yepamusoro-tembiricha yepombi masisitimu: Inokodzera kubhenda, kubhenda, uye welding mashandiro.

Welding uye Kupisa Kurapa ASTM A335 P91 Steel Tubes
Welding P91 inoda kuomerera kwakasimba kune maitiro kuchengetedza zvimiro zvayo:

Preheating: Zvakakosha kudzivirira hydrogen-induced kuputika.

Inter-pass tembiricha yekudzora: inochengetwa uchishandisa yemazuva ano induction yekudziya masisitimu.

Post-weld kupisa kurapwa (PWHT): Yakakosha kuwana iyo yaunoda microstructure uye kudzivirira kukundikana.

Welding electrodes: Inofanirwa kuenderana nekugadzirwa kwezvinhu zvevabereki.

Sei Kusarudza Womic Simbi ASTM A335 P91 Simbi Tubes?
Yakawedzera hesera: Yepamusoro-mhando P91 zvinhu kune zvese zvaunoda.

Unyanzvi: Chikwata chine ruzivo chekukutungamira kuburikidza nekusarudza zvinhu uye kushandisa.

Kuzvipira kune mhando: Chete zvinhu zvakanakisa kubva kune vakabvumidzwa vanogadzira.

Kune ako ese ASTM A335 P91 Type 2 zvinodiwa, bata Womic Steel nhasi. Chikwata chavo chakagadzirira kupa mhinduro dzinopfuura zvaunotarisira uye kuendesa emhando yepamusoro zvinhu zvemapurojekiti ako.
