Paipu idẹjẹ paipu ti ko ni titẹ ati fifa pẹlu awọn ohun-ini ti o lagbara ati ipata.Paipu idẹ jẹ paipu ipese omi ti o dara julọ ati pe o ti di omi tẹ ni kia kia ti awọn alagbaṣe ode oni ni gbogbo awọn ile iṣowo ibugbe.Yiyan ti o dara julọ fun awọn fifi sori ẹrọ paipu, alapapo ati itutu agbaiye.
Atẹle naa jẹ ifihan kukuru si ilana iṣelọpọ ti awọn ọpọn idẹ, ati awọn pato ati awọn ohun-ini ẹrọ ti awọn ọpọn idẹ ti o wọpọ.
Ilana iṣelọpọ ti tube idẹ:
1. Idaabobo gaasi yo ati itoju ooru → petele lemọlemọfún simẹnti ti Ejò tube billet → milling lati yọ awọn abawọn dada → mẹta-rola Planetary sẹsẹ → lori ila-coiling sinu coils → meta-jara isẹpo nínàá → ninà disiki → straightening, flaw erin, sizing → Imọlẹ annealing → isẹpo finishing → inspecta
2. Sisọ iyaworan oke → iyaworan lemọlemọfún simẹnti billet → Pilger ọlọ sẹsẹ → online annealing coil → mẹta-jara nínàá → disiki nínàá straightening, flaw erin, sizing→ lagbara convection imọlẹ annealing → apapọ finishing → Ayẹwo didara → lamination, apoti → pari ọja
3. Yo → (ologbele-tẹsiwaju) petele lemọlemọfún simẹnti Billet → extruding ẹrọ lati extrude billet → pilger ọlọ sẹsẹ → online annealing coil → mẹta-jara nínàá → disiki nínàá straightening, flaw erin, iwọn → Strong convective imọlẹ annealing → Strong convective imọlẹ annealing → extruding ẹrọ to extrude billet → pilger ọlọ sẹsẹ → online annealing coil
Lakoko sisẹ awọn ọpa paipu idẹ, kini ọna lati ṣe idiwọ ibajẹ wahala ti awọn ọpa paipu bàbà?
Lakoko sisẹ tube bàbà ati ọpá, paapaa idẹ zinc giga-giga ati idẹ silikoni-manganese, nitori ibajẹ aiṣedeede, aapọn inu yoo jẹ ipilẹṣẹ lori tube ati ọpa.
Aye ti aapọn inu yoo ja si ibajẹ ati paapaa fifọ awọn ohun elo lakoko sisẹ, lilo ati ibi ipamọ.
Ọna idena ni lati ṣe annealing iderun aapọn inu ni isalẹ iwọn otutu recrystallization ni akoko,
Paapa fun awọn ohun elo alloy wọnyẹn ti o ni itara si aapọn inu, gẹgẹbi idẹ-sinki giga, annealing iderun aapọn inu inu yẹ ki o ṣee ṣe laarin awọn wakati 24 lẹhin yiyi tabi nina.
Annealing iderun aapọn inu ni gbogbogbo ni a ṣe laarin 250°C ati 350°C, ati pe akoko naa le gun ni deede (bii diẹ sii ju 1.5-2.5h).
