Pipe yeSimbi Isina Kugadzika Yakanamirwa: Nei Kurapa Kwemhinduro Kuchikosha

Nhanganyaya

Pipe yeSimbi Isina Kugayiwaipombi yesimbi isina musono kana yakasungirirwa yakapiswa kusvika patembiricha yekurapa mhinduro chaiyo uye yakatonhodzwa nechiyero chakadzorwa kuti idzorere kuramba ngura, ductility uye chimiro chakafanana chesimbi. Kune austenitic grades dzakadai se304L ne316L, solution annealing inonyungudutsa chromium-rich carbides uye inoderedza njodzi yekuora kwepakati pegranular. Kune duplex stainless steels, inobatsirawo kusimbisa chiyero chinodiwa pakati peaustenite neferrite.

Pombi yakasungirirwa inoshandiswa mukugadzira makemikari, mumidziyo yezvekudya nezvinwiwa, masisitimu emishonga, nzvimbo dzemafuta negesi, nzvimbo dzinochinja-chinja kupisa, kugadziriswa kwemvura, mapaipi emugungwa uye sevhisi yemvura yakachena kwazvo. Vatengi vanofanira kutsanangura giredhi, chiyero chechigadzirwa, kuvakwa kusina musono kana kwakabatana, saizi, mamiriro ekurapa kupisa, kupedzwa kwenzvimbo, zvinodiwa pakuyera ngura uye chitupa chekuongorora.

Chii Chinoita Kuti Annealing Igadzirise Pipe Yesimbi Isina Kushanda?

Kudhirowa, kuumba, kusanganisa uye kushanda nekupisa zvinoshandura chimiro chepombi yesimbi isingatsvi. Mabasa aya anogona kukonzera kushushikana kwakasara, kuoma kwebasa, chromium-carbide precipitation kana kusawirirana zvakanaka kwechikamu. Kubatanidza mhinduro kunoshandiswa kudzorera chinhu chacho mumamiriro akakodzera kushandiswa kunodzivirira ngura uye kugadzirwa kunotevera.

Kunyungudutsa Chromium Carbides

Simbi dzisingatsvi dzeAustenitic dzinogona kugadzira chromium carbides kana dzikaiswa munzvimbo dzakati tembiricha dzepakati kwenguva yakakwana. Chromium inotorwa kubva munzvimbo dzakapoteredza miganhu yezviyo, zvichisiya nzvimbo dzakaderera chromium. Nzvimbo idzi dzinogona kukanganiswa nengura yepakati pegranular munzvimbo ine hukasha.

Panguva yekurapwa kwemvura, pombi inodziiswa zvakakwana kuti inyungudise macarbides aya mu austenitic matrix. Kutonhora nekukurumidza kunoderedza kunaya kwemvura zvakare. Kutenderera kwekupisa kunoenderana negiredhi, ukobvu hwechikamu, dhizaini yechoto uye mamiriro ezvinhu.

Kudzorera Ductility Mushure meKushanda Nechando

Pombi inodhonzwa nechando inosimba uye inoomarara zvakanyanya kuburikidza nekuomarara, asi kureba kwayo uye kugona kwayo kunopera. Kubatanidza kunobvumira kuti pave nekudzokororwa kwecrystallization, zvichideredza kuomarara uye kudzorera kugona kwayo. Izvi zvakakosha kana pombi yacho yakotamiswa, yakawedzerwa, yaputirwa, yakabatanidzwa kana kuumbwa kuita musanganiswa wemidziyo.

Kudzora Duplex Phase Balance

Simbi dzisina ngura mbiri dzine ferrite neaustenite. Kupisa kusina kukodzera kunogona kukonzera ferrite yakawandisa kana kuti inokuvadza pakati pesimbi, zvichideredza kuomarara uye kuramba ngura. Kugadziriswa kwekupedzisira kwemvura kunoteverwa nekutonhora nekukurumidza zvakakwana saka idanho rakakosha rekugadzira duplex ne super duplex pipe.
