ASTM SA210 GrAisimbi ine kabhoni shoma (C≤0.27%), ine zvinhu zvakaita semanganese (Mn 0.93% max) uye silicon (Si 0.10-0.20%) kuitira kuti ive nechokwadi chekuti michina yacho inoshanda zvakanaka uye kuti inogona kushandiswa zvakanaka.

Kuwanda kwesarufa nephosphorus (P≤0.035%, S≤0.035%) kunowedzera kusimba kwe oxidation pakupisa kwakanyanya.

Kushanda kwakanaka kwazvo

Kudzivirira kupisa kwakanyanya: tembiricha yekushanda kwenguva refu ≤450℃, kwenguva pfupi kusvika 480℃.

Simba rekudzvanya kwepamusoro: rakakodzera mapaipi eboira ane simba repakati nepasi ≤5.88MPa.

Kuenderana kwemaitiro: nyore kusundira, kukotama uye kutonhora maitiro, akakodzera machira eboiler tube, misoro nezvimwe zvikamu.

Mitemo yakasimba

Tevedzera zvinodiwaASTM SA210 GrAmitemo, uye kupasaGB/T 3087, ASME nezvimwe zvitupa zvekuona kuti zvakachengeteka uye zvakavimbika.

ASTM SA210 GrA pombi yesimbi isina musono isarudzo yakanaka kune minda inotevera:

Indasitiri yebhaira: madziro emvura yebhaira, superheater, economizer nezvimwe zvinhu zvakakosha.

Chinochinja kupisa: mapaipi e condenser uye evaporator muindasitiri ye petrochemical.

Simba remagetsi: mapaipi ekufambisa mhute uye masisitimu ekubatsira ezviteshi zvemagetsi zvinopisa.

Kushanda zvakanaka kwemari: Kana tichienzanisa nemapaipi esimbi alloy, mapaipi esimbi yekabhoni eASTM SA210 GrA anoderedza zvakanyanya mari yekutenga uku achizadzisa zvinodiwa pakushanda.

Kuwanikwa kwakagadzikana: Sezvinhu zvepaboiler tube, zvinhu zviri mumusika zvakakwana uye nguva yekutumira ipfupi.

Tinopa nzira dzekucheka dzakagadzirirwa isu, bvunzo dzisingaparadze (UT/RT), mushumo wezvinhu uye mamwe mabasa eASTM SA210 GrA mapaipi esimbi asina musono, uye tinotsigira kugoverwa kwezvinhu pasi rose.

ASTM SA210 GrAPombi yesimbi yekabhoni isina musono yave chigadzirwa chemhando yepamusoro muminda yemaboilers uye ma heat exchangers nekuda kwekushanda kwayo kwakasimba uye hupfumi hwayo. Kana uchida parameters dzehunyanzvi kana mutengo, ndapota taura nechikwata chedu chehunyanzvi!
