ASTM A213 T12(ASME SA213 T12) ipombi yesimbi isina musono ine simbi shoma yakagadzirirwa kushandiswa pakupisa kwakanyanya.
Zvinhu zvayo zvikuru zvinosanganisa simbi 0.80–1.25% yechromium uye 0.44–0.65% yemolybdenum, izvo zvinoiisa muchikamu chesimbi yechromium-molybdenum alloy. Inoshandiswa zvakanyanya munzvimbo dzine tembiricha yakakwira uye ine kumanikidzwa kwakakwira senge mabhoyila, ma superheater, uye ma heat exchangers.
Pombi yeT12 ine simba rekudhonza risingasviki 415 MPa uye simba rekuburitsa risingasviki 220 MPa.
Chinzvimbo cheUNS chegiredhi iri ndiK11562.
Botop Steel inyanzvi uye yakavimbika mukutengesa mapaipi esimbi esimbi ye alloy muChina, inokwanisa kupa mapurojekiti ako nekukurumidza nemhando dzakasiyana dzemapaipi esimbi ye alloy, kusanganisiraT5 (K41545), T9 (K90941), T11 (K11597), T12 (K11562), T22 (K21590)uyeT91 (K90901).
Zvigadzirwa zvedu zvine hunhu hwakavimbika, zvine mutengo unokwikwidzana, uye zvinotsigira kuongororwa kwevamwe.
Kuti muwane maodha kana rumwe ruzivo, ndapota taurai nesu nhasi!
