Insimbi Engagqwali Ephindwe Kabili Ye-S31803: Ukumelana Okuphezulu Kokugqwala kanye Nokuqina Okuphezulu Kwezicelo Zezimboni

I-S31803, eyaziwa nangokuthi i-Duplex 2205 noma i-F60, iyizinga elihlonishwa kakhulu lensimbi engagqwali ye-duplex emakethe yomhlaba wonke. Njengoba iqashelwa ngaphansi kwe-Unified Numbering System (UNS), le nto iyaziswa ngokumelana kwayo nokugqwala okumangalisayo, amandla aphezulu okusebenza, kanye nokusebenza okuguquguqukayo ezindaweni ezinzima.

Ukwakheka Kwamakhemikhali Abalulekile kanye Nesakhiwo

Insimbi engagqwali ye-S31803 ephindwe kabili ifaka ingxube elinganiselayo yezinto ezixubayo eziletha izakhiwo zayo ezivelele:

• I-Chromium (Cr):Cishe u-22% - Kuthuthukisa ukumelana nokugqwala, ikakhulukazi ngokumelene nokugqwala kwemigodi kanye nokuqhekeka.

• I-Nickel (Ni):Cishe 5.0–6.0% – Kuthuthukisa ukuqina kanye nokuqina.

• I-Molybdenum (Mo):Cishe u-3.0% - Kukhulisa ukumelana nokugqwala kwendawo, ikakhulukazi ezindaweni ezicebile nge-chloride.

• I-nitrogen (N):Cishe u-0.18% - Kwandisa amandla futhi kunegalelo ekumelaneni nokugqwala kokucindezeleka.

Isakhiwo esincane esiyingqayizivele esinezigaba ezimbili, esihlanganisa izigaba ze-ferritic neze-austenitic, siphumela ezimpahleni zemishini ezicishe ziphindwe kabili kunezensimbi ezivamile ze-austenitic engagqwali ngenkathi zigcina ukuqina nokuqina okuhle kakhulu.

Izakhiwo Nezinzuzo Ezivelele

Ukumelana Nokugqwala Okuthuthukisiwe

I-S31803 iphumelela kakhulu ekumelaneni nezinhlobo ezahlukene zokugqwala, okuhlanganisa:

• Ukugqwala Kwezimbobo Nokuqhekeka Kwemifantu:Okuqukethwe kwayo okuphezulu kwe-chromium kanye ne-molybdenum kuyivumela ukuthi isebenze kahle kakhulu ezindaweni ezine-chloride.

• Ukuqhekeka Kokucindezeleka:Isakhiwo se-duplex sinikeza ukumelana okukhulu kokuqhekeka ngaphansi kokucindezeleka, ngisho nalapho kuvezwa ezindabeni ezinolaka.

Amandla Aphezulu Okusebenza Kwemishini

• Amandla Okuqinela Aphezulu:Ngokuvamile, amandla okudonswa kwe-S31803 adlula i-500 MPa, okwenza kube kuhle kakhulu ekusetshenzisweni komfutho ophezulu.

• Ukuqina Okuthuthukisiwe:Isakhiwo esincane esilinganiselayo asigcini nje ngokuqinisa amandla kodwa futhi siqinisekisa ukuqina okuthembekile kanye nokuguquguquka, okubalulekile ezindaweni zezimboni eziguquguqukayo.

Ukushibilika Okuhle Kakhulu

Nakuba kudingeka ukunakwa okukhethekile ngesikhathi sokushisela ukuze kugwenywe ukuwohloka endaweni ethinteke ukushisa, amasu okushisela afanele kanye nokwelashwa ngemva kokushisela kungaqinisekisa ukuthi amalunga aqinile, angenasici. Lokhu kwenza i-S31803 ibe yisinqumo esiwusizo kokubili emsebenzini wokwakha kanye nokulungisa.

Izicelo Zezimboni

Insimbi engagqwali ye-S31803 ephindwe kabili isetshenziswa kakhulu ezimbonini ezahlukahlukene ngenxa yokuhlanganiswa kwayo okulinganayo kwamandla nokumelana nokugqwala. Izindawo ezibalulekile zokusetshenziswa zifaka:

• Imishini Yokucubungula Amakhemikhali:Kuhle kakhulu kuma-reactor, amathangi okugcina izinto, kanye nezinhlelo zamapayipi lapho kudingeka khona ukumelana namakhemikhali anolaka.

• Imboni Kawoyela Negesi:Kusetshenziswa kakhulu kumapayipi, amavalvu, kanye nokufakwa, ikakhulukazi ngaphansi kwezimo zokucindezela okuphezulu kanye ne-chloride ephezulu.

• Ubunjiniyela Basemanzini kanye Nokwakha Imikhumbi:Ukumelana kwayo nokugqwala kwamanzi anosawoti kwenza ifaneleke ezakhiweni zasogwini, izinto zokwakha zasolwandle, kanye nezinye izinhlelo zokusebenza zasemanzini.

• Izikhungo Zokukhiqiza Amandla:Baqashwe ezitshalweni zikagesi nasezikhungweni zenuzi lapho ubuqotho besakhiwo kanye nokusebenza kwesikhathi eside kubalulekile khona.

• Izingxenye Zokwakha Nezokwakha:Isiphetho sayo esihle kanye nokuqina kwayo kuholele ekusetshenzisweni kwayo ezakhiweni zesimanje kanye nezicelo zobuhle

   

Ukuhambisana neMigomo Yomhlaba Wonke

Insimbi engagqwali ye-S31803 ephindwe kabili ihambisana nezindinganiso ezibalulekile zamazwe ngamazwe nezesizwe, okuqinisekisa ukuthembeka kwayo kanye nekhwalithi yayo. Isibonelo:

• I-ASME B16.11:Icacisa ukusetshenziswa kwayo ekukhiqizweni kwe-socket weld kanye ne-threaded pipe fittings.

• I-ASTM A240/A240M:Inikeza iziqondiso zamapuleti ensimbi engagqwali asetshenziswa ezinhlotsheni ezahlukene zokusebenza.

• I-EN 10088-2:Imininingwane ngezidingo zemikhiqizo yensimbi engagqwali eYurophu.

Lokhu kunamathela ezindinganisweni eziqinile kuqinisekisa ukuthi i-S31803 iyahlangabezana nezidingo zezicelo ezibalulekile emhlabeni jikelele.

Isiphetho

Insimbi engagqwali ye-S31803 ephindwe kabili ivelele njengento eguquguqukayo neqinile efanelekile ezindaweni zezimboni ezidinga kakhulu. Inhlanganisela yayo enhle kakhulu yamandla aphezulu, ukumelana nokugqwala okuphezulu, kanye nokushintshwa okuthembekile kuyenza ibe yisinqumo esiphezulu kuzo zonke imikhakha efana nokucubungula amakhemikhali, uwoyela negesi, ubunjiniyela basolwandle, ukukhiqizwa kwamandla, kanye nokwakha. Njengoba izimboni ziqhubeka nokucindezela imikhawulo yokusebenza nokuqina, i-S31803 isalokhu iyinto ekhethwayo enikeza inani elihlala njalo nokuphepha.

Ukuze uthole imininingwane eningiliziwe yobuchwepheshe kanye nezixazululo ezenziwe ngokwezifiso, ochwepheshe bemboni bakhuthazwa ukuthi babheke amashidi edatha abalulekile futhi baxhumane nabaphakeli abathembekile.
