Ukukhiqizwa kwenduku eyindilinga yensimbi engagqwali enobukhulu obuhlukahlukene, ikhwalithi enhle kanye nentengo ephansi
Izinzuzo zezinduku zensimbi engagqwali zibonakala kakhulu kulezi zici ezilandelayo: Okokuqala, inokumelana okuhle kakhulu nokugqwala, ingahlala izinzile ezindaweni ezinomswakama nezine-asidi, futhi akulula ukugqwala. Okwesibili, izinduku zensimbi engagqwali zinamandla aphezulu nokuqina futhi zifanele ukuthwala imithwalo emikhulu ukuqinisekisa ukuphepha kwesakhiwo. Ngaphezu kwalokho, ubuso bayo bubushelelezi, kulula ukuhlanza, buhlangabezana nezindinganiso zokuhlanzeka, futhi bufanelekela ikakhulukazi izimboni zokudla nezokwelapha. Okokugcina, ubuhle kanye nokuqina kwezinduku zensimbi engagqwali kuzenza zisetshenziswe kabanzi ekwakheni nasekuhlobiseni, okuthuthukisa umklamo jikelele.

Ipayipi Lensimbi Engagqwali Elingamelani Nokushisa Le-ASTM Elisezingeni Eliphezulu 431 631 Ishubhu Lensimbi Engagqwali
Amapayipi ensimbi engagqwali enziwe ngensimbi engagqwali enokuqukethwe kwe-chromium okungu-≥10.5% (njengamazinga ajwayelekile angu-304 no-316L). Anamandla aphezulu (amandla okudonsa angu-≥515MPa), ukumelana okuhle kakhulu nokugqwala (ifilimu yokuphambuka kobuso imelana nokugqwala kwe-asidi/usawoti) kanye nokuphepha okuhlanzekile (ukuphela kobuso bezinga lokudla okungu-Ra≤0.8μm). Akhiqizwa ngezinqubo zamapayipi okugoqa okubandayo noma okushiswa ngesivinini esiphezulu futhi asetshenziswa kabanzi kumapayipi amakhemikhali (316L amelana ne-asidi), izakhiwo zokwakha (ama-keel odongeni angamakhethini angu-304), imishini yezokwelapha (amapayipi ahlanzekile aqondile) kanye nemishini yamandla (amapayipi okudlulisa okushisa aphansi kakhulu e-LNG). Yizinto eziyisisekelo eziyinhloko emkhakheni wokukhiqiza okuphezulu.

Ukumelana Nokucindezela Okumelana Ne-asidi 316 304 Ipayipi Lensimbi Engagqwali Eligoqekile Elingenamthungo 201
Ipayipi lensimbi engagqwaliiyinto yensimbi eyindilinga ende engenalutho, esetshenziswa kabanzi emipayipini yezimboni efana ne-petroleum, amakhemikhali, ezokwelapha, ukudla, imboni elula, izinsimbi zemishini, kanye nezingxenye zesakhiwo semishini. Ngaphezu kwalokho, uma amandla okugoba kanye nokugoba efana, isisindo silula, ngakho-ke sisetshenziswa kabanzi ekwenziweni kwezingxenye zemishini kanye nezakhiwo zobunjiniyela. Isetshenziswa kakhulu futhi efenisha kanye nezitsha zasekhishini.

Osayizi Abagcwele Ipuleti Lensimbi I-AISI 201/304/316 SS304L 316L 430 Elishisayo/Elibandayo Eligoqiwe Eliyi-2b Ba 8K Mirror No. 1 Elipholishiwe Elinezinhlayiya Zezinwele Ezinezinhlayiya Ezinezinhlayiya Zensimbi Engagqwali
Ishidi lensimbi engagqwaliishidi lensimbi eliyisicaba, elingunxande eligoqwe ngensimbi engagqwali (ngokuyinhloko liqukethe izinto ezixubayo njenge-chromium ne-nickel). Izici zalo eziyinhloko zifaka phakathi ukumelana nokugqwala okuhle kakhulu (ngenxa yefilimu yokuvikela i-chromium oxide eziphilisayo eyakhiwe ebusweni), ubuhle nokuqina (ubuso bayo obukhanyayo buvumelana nezindlela ezahlukene zokwelapha), amandla aphezulu, kanye nezakhiwo ezihlanzekile nezihlanzekile kalula. Lezi zimfanelo ziyenza ibe yinto ebalulekile ebaluleke kakhulu ezinhlotsheni eziningi zezicelo, kufaka phakathi izindonga zamakhethini okwakha kanye nokuhlobisa, imishini yasekhishini kanye nezinto zikagesi, amadivayisi ezokwelapha, ukucubungula ukudla, izitsha zamakhemikhali, kanye nezokuthutha. Iphinde inikeze ukusebenza kahle kakhulu (ukwakha kanye nokushisela) kanye nenzuzo yemvelo yokuba isetshenziswe kabusha ngo-100%.

2b/Ba/Cha. 1/Cha. 4/Hl/8K Ss Coil Cold Rolled/Hot Rolled 201 304 316 309S 310S 321 430 904L Stainless Steel Coil
Ikhoyili yensimbi engagqwaliiyinto yensimbi enamandla futhi engagqwali, evame ukwenziwa ngamashidi ensimbi engagqwali ngezinqubo zokugoqa ezishisayo nezibandayo. I-coil yensimbi engagqwali yakhiwe ngokuyinhloko ngensimbi, i-chromium, i-nickel, nezinye izakhi zensimbi. Inqubo yayo yokukhiqiza ihlanganisa ukulungiswa kwezinto zokusetshenziswa, ukuncibilikisa, ukugoqa okushisayo nokubandayo, kanye nokwelashwa kwendawo. Ukuncibilikisa kuyisinyathelo esibalulekile ekukhiqizweni kwe-coil yensimbi engagqwali futhi ingenye yezinqubo eziyinkimbinkimbi kakhulu ekukhiqizweni komkhiqizo wensimbi engagqwali.

Amapayipi ensimbi engagqwali angenamthungo e-ASTM A312 304L 316L 6mtr Angenamthungo Umphezulu Ompunga Omhlophe Ohlanganisiwe Oqoshiwe
Ipayipi lensimbi engagqwaliiwucezu olude olungenalutho lwensimbi ye-alloy engagqwali. Ingxenye yayo eyinhloko yinsimbi, equkethe okungenani i-10.5% chromium (Cr). Izinto ezifana ne-nickel (Ni) kanye ne-molybdenum (Mo) zivame ukungezwa ukuthuthukisa izakhiwo ezithile. Izici zayo ezivelele kakhulu ukumelana kwayo nokugqwala kanye ne-oxidation okumangalisayo, ngenxa yefilimu eqinile engashukumi eyakhiwe ebusweni bayo, evumela ukusetshenziswa kwayo kabanzi ezindaweni ezinomswakama, ezigqwala ngamakhemikhali, noma ezishisa kakhulu. Ipayipi lensimbi engagqwali liphinde linikeze amandla amahle kakhulu, ukuqina, ukuhlanzeka (kulula ukuhlanza nokubulala amagciwane), kanye nokusebenza kahle komshini kanye nokushintshwa. Izinto ezivamile zifaka izinsimbi ezingagqwali ze-austenitic ezifana ne-304 (inhloso ejwayelekile) kanye ne-316 (emelana nokugqwala kakhulu, equkethe i-molybdenum). Ukusetshenziswa kwayo kuhlukahlukene kakhulu, kufaka phakathi ukuhlobisa kwezakhiwo (izinsika, izinsika zokuvikela), ukuthuthwa koketshezi (amanzi, igesi, imithombo yamakhemikhali), ukucubungula ukudla neziphuzo, amadivayisi ezokwelapha, ukukhiqizwa kwezimoto, izimboni zamandla (uphethiloli, amandla enuzi), izimpahla zasekhaya, kanye nezinsimbi zokunemba. Kuyinto ebalulekile ebalulekile embonini yanamuhla nasempilweni. Ukwelashwa kwendawo okufana nokupholisha kanye nokuqhuma kwesihlabathi kungasetshenziswa ukuhlangabezana nezidingo zobuhle nokusebenza kahle. Sekukonke, amapayipi ensimbi engagqwali ayizinto zamapayipi ezithandwa kakhulu ezindaweni eziningi ngenxa yokuqina kwawo, inhlanzeko, ubuhle, kanye nokuguquguquka kwawo.
