ASTM A335 simbi pombi inofanira kunge isina musono.
Seamless simbi pombi isimbi pombi isina welds mukati.
Sezvo seamless simbi pombi isina welded seams muchimiro chayo, inodzivirira njodzi dzinogona kuitika dzekuchengetedza dzinogona kubatanidzwa ne weld quality nyaya.Iyi ficha inobvumira iyo isina musono pombi kuti imire kumanikidza kwakakwirira, uye homogeneous yayo yemukati chimiro inowedzera kuvimbisa kutendeseka uye kuchengetedzeka kwepombi munzvimbo dzakanyanya-kudzvanywa.
Pamusoro pezvo, kuvimbika kweASTM A335 tubing kunokwidziridzwa nekuwedzerwa kweiyo chaiyo alloying zvinhu zvepamusoro-tembiricha uye yakakwirira-kudzvanywa mamiriro.
Marudzi ekurapa kwekupisa anowanikwa eP9 zvinhu anosanganisira yakazara kana isothermal annealing, pamwe nekujairira uye kupisa.Kudzikamisa uye kupisa kunopisa kunosvika 1250°F [675°C].
Iwo makuru alloying zvinhu zveP9 ndizvoCruyeMo, ayo ari chromium-molybdenum alloys.
Cr (Chromium): Sechinhu chikuru cheiyo alloy, Cr inopa yakanakisa yepamusoro-tembiricha simba uye kuramba kune oxidation.Iyo inoumba dense chromium oxide firimu pamusoro pesimbi, ichiwedzera kugadzikana uye kushora kupikisa kwepombi pakupisa kwakanyanya.
Mo (Molybdenum): Kuwedzerwa kweMo kunowedzera kusimba uye kuoma kwema alloys, kunyanya munzvimbo dzepamusoro-tembiricha.Mo zvakare inobatsira kuvandudza kusimba kweiyo zvinhu, kureva kugona kuramba deformation pasi pekuratidzwa kwenguva refu kwekupisa.
