Kutanga, ngatikurukurei nezvenyaya yeASTM A335 P22Pombi yesimbi ye alloy. Pombi iyi yesimbi inoshandisa simbi yemhando yepamusoro yekabhoni kana simbi ye alloy sezvinhu zvikuru uye inogadzirwa kuburikidza nekudhirowa kwakanyatsonaka kana maitiro ekumonera anopisa. Kudzora kwakanyatsojeka kwehuwandu hwekabhoni, zvinhu zve alloy uye zvinhu zvinotevedzana mupombi yesimbi kunoita kuti pombi yesimbi ive yakasimba uye yakasimba. Pamusoro pezvo, kuramba ngura kwepombi yesimbi ye alloy yeASTM A335 P22 kwakanakawo, uye inogona kuchengetedza kushanda kwayo uye hupenyu hwebasa kwenguva yakareba munzvimbo dzakaoma.
Tevere, ngatidzidzei nezvemaitiro ekugadziraASTM A335 P22Pombi yesimbi ye alloy. Maitiro ekugadzira anosanganisira zvinonyanya kukosha zvakaita sekunyungudutsa, kutenderedza uye kupisa. Munguva yekunyungudutsa, zvinhu zvakagadziriswa zvinopiswa kusvika zvanyunguduka uye zvinhu zvinodiwa zve alloy zvinowedzerwa kuti pave nemakemikari anodiwa uye chimiro che alloy. Munguva yekutenderedza, kurongeka kwehukuru, mhando yepamusoro uye hunhu hwemakanika epombi yesimbi zvinovimbiswa nekudzora nemazvo parameters akadai sekupisa, kumhanya uye kushanduka. Pakupedzisira, kubatana kwekupisa kunobatsira kubvisa kushushikana kwasara mukati mepombi yesimbi uye kuvandudza kugadzikana kwayo uye kugara kwenguva refu.
Hunhu hwekushanda kweASTM A335 P22Mapaipi esimbi akagadzirwa nesimbi ndeimwe yezvikonzero zvinoita kuti ifarirwe. Chekutanga, pombi yesimbi ine simba rakawanda uye yakasimba, inogona kutsungirira kumanikidzwa kwakanyanya uye kukanganiswa, uye inosangana nezvinodiwa nemamiriro akasiyana-siyana ekushanda akaomarara. Chechipiri, ine simba rakanaka rekudzivirira ngura uye inogona kutsungirira kukanganiswa kwezvinhu zvakasiyana-siyana zvemakemikari kuti ive nechokwadi chekuti inoshanda kwenguva refu. Pamusoro pezvo, pombi yesimbi akagadzirwa nesimbi yeASTM A335 P22 ine simba rakanaka rekudzivirira kupisa kwepamusoro uye inogona kuchengetedza hunhu hwakagadzikana hwemakanika nemakemikari pasi pemamiriro ekunze ekupisa kwakanyanya.
Imhaka chaiyo yekushanda kwakanaka uku kwakaita kuti ASTM A335 P22 alloy steel pipe ishandiswe zvakanyanya muminda yakawanda. Mundima yemafuta nemakemikari, pombi yesimbi inoshandiswa kugadzira mapaipi ane tembiricha yakakwira uye ane pressure yakakwira uye michina yekuona kuchengetedzeka uye kugadzikana kwemaitiro ekugadzira. Mundima yesimba,ASTM A335 P22Pombi yesimbi ye alloy inoshandiswa zvakanyanya mumidziyo mikuru yakadai semaboiler nema superheater, ichitsungirira kupisa kwakanyanya uye utsi hwemhepo ine simba rakawanda nemvura inopisa, zvichipa vimbiso yakavimbika yekugadzira simba. Pamusoro pezvo, mumunda weindasitiri yenyukireya, pombi yesimbi inoitawo basa rakakosha mukugadzirwa kwemapombi nemakontena mumagetsi enyukireya kuitira kuve nechokwadi chekushandiswa kwakachengeteka kwesimba renyukireya.
Kuwedzera kune nzvimbo dzekushandisa dziri pamusoro apa,ASTM A335 P22Pombi yesimbi ye alloy inogonawo kugadziriswa zvichienderana nezvinodiwa nevatengi kuti ienderane nezvinodiwa zvekushandisa mumamiriro ezvinhu chaiwo. Semuenzaniso, nekugadzirisa ma parameter akadai sehukobvu hwemadziro, dhayamita uye kureba kwepombi yesimbi, inogona kusangana nezvinodiwa nemapurojekiti akasiyana. Panguva imwe chete, pombi yesimbi inogonawo kugadziriswa pamusoro zvichienderana nezvinodiwa nevatengi, zvakaita sekupfapfaidza anti-corrosion coating, galvanizing, nezvimwewo, kuti ivandudze kuramba kwayo ngura uye hupenyu hwebasa.
Pombi yesimbi yeASTM A335 P22 alloy, sechinhu cheindasitiri chine mashandiro akanaka, ine basa rakakosha muminda yakawanda. Nekufambira mberi kwetekinoroji uye kuwedzera kuri kuita minda yekushandisa, tine chikonzero chekutenda kuti pombi yesimbi yeASTM A335 P22 alloy icharamba ichibatsira mukusimudzira maindasitiri mune ramangwana.
