Emhlabeni wezinhlelo zokusebenza zezimboni, ukukhetha kwezinto kungaba nomthelela omkhulu ekusebenzeni, ukuqina, kanye nempumelelo iyonke yephrojekthi. Izinto ezisetshenziswa kakhulu ezinhlelweni zamapayipi ipayipi lensimbi engagqwali, ikakhulukazi amabanga 304 no-316. Nakuba kokubili kuyizinketho ezidumile, anezici ezihlukile eziwenza afanelekele ukusetshenziswa okuhlukile. Lo mhlahlandlela uzobheka kabanzi umehluko phakathi kwepayipi lensimbi yesiShayina engu-304 kanye nepayipi lensimbi engu-316, likusize wenze isinqumo esinolwazi ngephrojekthi yakho elandelayo.
**304 ipayipi lensimbi engagqwali: umkhiqizo oyinhloko osebenzayo **
304 Ipayipi Lensimbi Engagqwali livame ukubizwa ngokuthi “ihhashi lokusebenza” lomndeni wensimbi engagqwali. Ihlanganiswe ngokuyinhloko ngensimbi, i-chromium (18%), ne-nickel (8%), leli banga laziwa ngokumelana nokugqwala okuhle kakhulu, ukumila kahle, kanye nokushisela. Isetshenziswa ezimbonini eziningi ezahlukahlukene, kufaka phakathi ukucubungula ukudla, ukugcinwa kwamakhemikhali, kanye nezicelo zokwakha.
Enye yezinzuzo eziyinhloko zensimbi engagqwali engu-304 ukuthi ingakwazi ukumelana namazinga okushisa ahlukahlukene, okwenza ifaneleke kokubili izicelo zokushisa eziphakeme neziphansi. Ngaphezu kwalokho, ayiyona i-magnetic futhi inendawo ebushelelezi, ebalulekile ekuhlanzekeni ezimbonini ezihlobene nokudla. Nokho, nakuba insimbi engagqwali engu-304 inokumelana kahle ne-oxidation nokugqwala, ayisebenzi kahle ezindaweni ezigqwala kakhulu, ikakhulukazi lezo eziqukethe ama-chloride.
**316 ipayipi lensimbi engagqwali: iqhawe lokumelana nokugqwala **
Ngakolunye uhlangothi, ngezinhlelo zokusebenza ezidinga ukumelana nokugqwala okuthuthukisiwe, ipayipi lensimbi engagqwali engu-316 livame ukubhekwa njengenketho engcono kakhulu. Leli banga liqukethe amaphesenti aphezulu e-nickel (10%) kanye ne-molybdenum (2%), ethuthukisa kakhulu ukumelana kwayo nokugqwala kwemigodi nokugqwala, ikakhulukazi ezindaweni ezinothe nge-chloride. Ngakho-ke, i-316 insimbi engagqwali iyimpahla ekhethwayo yezicelo zasolwandle, ukucubungula amakhemikhali, kanye nemboni yezemithi.
Ukwengezwa kwe-molybdenum akugcini nje ukuthuthukisa ukumelana nokugqwala, kodwa futhi kuthuthukisa amandla onke nokuqina kwempahla. Amapayipi ensimbi engagqwali angu-316 akwazi ukumelana namazinga okushisa aphezulu futhi awathinteki kalula ekuqhekekeni kokugqwala kwengcindezi. Lokhu kuzenza zilungele ukusetshenziswa ezindaweni ezinokhahlo, njengendawo egudle ugu noma izitshalo zamakhemikhali ezivame ukuchayeka ezintweni ezigqwalayo.
**Umehluko Oyinhloko: Uhlolojikelele Lokuqhathanisa**
1. **Ukumelana Nokugqwala**: Nakuba womabili amapayipi ensimbi engu-304 kanye nangu-316 enokumelana nokugqwala okuhle, angu-316 enza kangcono kunokungu-304 ezindaweni ezinokuchayeka kwe-chloride okwengeziwe. Lokhu kwenza i-316 ibe inketho ekhethwayo yezicelo zasolwandle namakhemikhali.
2. **Ukwakheka**: Umehluko omkhulu ekubunjweni ukuthi i-molybdenum yengezwa ensimbi engagqwali engu-316, ethuthukisa ukumelana kwayo nokugqwala kwemigodi nokugqwala.
3. **Izindleko**: Ngokuvamile, ipayipi lensimbi engu-316 libiza kakhulu kunepayipi lensimbi engagqwali engu-304 ngenxa yokwengezwa kwezakhi ze-alloying. Ngakho-ke, ukukhetha phakathi kwalokhu kokubili kuvame ukuncika ezidingweni ezithile zesicelo kanye nokucatshangelwa kwesabelomali.
4.**Uhlelo lokusebenza**: Insimbi engagqwali engu-304 ifanele ukusetshenziswa okubanzi, okuhlanganisa ukucutshungulwa kokudla kanye nokusetshenziswa kokwakha, kuyilapho i-316 insimbi engagqwali yakhelwe izimo ezidinga kakhulu, ezifana nokucutshungulwa kwasolwandle namakhemikhali.
**Ekuphetheni**
Ukukhetha ipayipi lensimbi engagqwali lase-China 304 noma ipayipi lensimbi engu-316 ekugcineni kuncike ezidingweni ezithile zephrojekthi yakho. Ukuqonda umehluko ekwakhekeni, ukumelana nokugqwala, nokufaneleka kohlelo lokusebenza kuzokusiza wenze isinqumo unolwazi. Kungakhathaliseki ukuthi udinga ukuguquguquka kwe-304 noma ukuqina okuthuthukisiwe kwe-316, womabili amabanga anikeza ukusebenza okuphezulu nokuthembeka emikhakheni yawo. Tshala imali epayipini lensimbi engagqwali elifanele ngezidingo zakho ukuze uqinisekise impumelelo yephrojekthi yakho iminyaka ezayo.
