Okuqukethwe okuphezulu kwe-chromium kukhuthaza futhi kugcinwe ifilimu nje evikela impahla ezindaweni eziningi ezilonakalisayo.
Insimbi engu-316 inensimbi engagqwali inekhabhoni eningi kuyo kune-316l. Lokhu kulula ukukhumbula, njengoba i-L imile "ephansi."
Amapayipi e-Spools aklanywe kusuka kumapayipi angenakuqhathaniswa namapayipi (e.g. ama-elbows, ama-flanges, amathayela, njll.) Ezitolo zokubola.
I-Alloy 904L ihluphuke ezinye izinsimbi ze-autenitic ezingenasici ngenxa yezinga eliphakeme lokwabiwa kwe-nickel ne-molybdenum.
Amanani aphezulu e-nickel ne-chromium e-autenitutic steress acrenless anikeza izakhiwo ezinhle kakhulu zemishini, kanye nokuphikiswa okuhle kakhulu kokugqwala.
Alloy 347h (us s3409) ipuleti yensimbi engagqwali yi-carbon ephakeme (0.04 ¨c 0.10) inguqulo ye-alloy.
Lesi sigaxa sepayipi esingenasici sivame ukuthathwa ukuze sikwazi ukwenza ukuxhumana kwamanye ama-spools futhi sithanda kakhulu ezisetshenziselwa izimboni ezahlukahlukene ezinjengezitshalo zamandla kanye nokuhlaziywa kukaphethiloli zidinga amapayipi afudumele.
Insimbi engenasici 904L \ 15539 impahla ingasetshenziswa ukwenza ishidi elishisayo nelibandayo, imikhiqizo eqediwe, imigoqo ye-rolled, kanye namapayipi athuliwe kanye namaphrofayili ezicelo zokucindezela.
I-304 insimbi engagqwali inobuthakathaka obunye: Itholakala ekugculweni okuvela kwizixazululo ze-chloride noma ezindaweni zesawoti ezifana nogu.
Lapho ukhetha ama-sterainless steres okufanele ubekezelele izindawo ezilonakalisayo, ama-autenitic angenazinsimbi ajwayele ukusetshenziswa.
I-SAE 304 Insimbi Engagqwali Ukuvuselelwa KwePipe Spools
Ama-spools ensimbi angenasici asebenza kumakhasimende ngoba awaphuthelwa noma yiziphi izingxenye futhi asusa ubunzima bokufakwa kwe-inkazi.

I-316l, nokho, ukukhetha okungcono kwephrojekthi edinga ukufudumala okuningi ngoba i-316 itholakala kalula ekuwohlokeni kwamandla ku-316L (ukugqwala ngaphakathi kweWeld).
Ngokuvamile balungisa kalula ngenxa yezinto abavezwa; Ama-electrolyte ama-electrolyte anemvelo. Ukuqapha okwamukelekayo kumele kwenziwe lapho kusebenza amasistimu wepayipi.
Alloy 347 (uns s34700) nguColumbium waqinisa ipuleti yensimbi engenacala engenacala ngokumelana kahle nokuphikiswa okujwayelekile kanye nokuphikiswa okungcono ezimweni eziqinile ze-oxidizing eziqinile kune-321 (uns s32100).
Ukwakheka kwepayipi kubaluleke kakhulu ngoba ukwakhiwa komkhumbi nezinye izimboni zasemanzini zidinga amapayipi amakhulu. Amapayipi Spools adala izinzuzo ezinhle ngoba anciphisa ukulinganiselwa kwesikhala esizeni.
Ngale nzuzo, yonke ipayipi esebenzisa izimboni inethuba elihle lokukhulisa ukusebenza kahle kohlelo lwepayipi futhi yehlise isidingo sabo sokusebenza nesikhathi.
I-alloy inokumelana ne-oxidation enhle kanye namandla aqhakazayo ku-1500¡Ãf (816¡Ãc). Iphinde futhi ibe nobunzima bokushisa okuphansi okuphansi.
Amapayipi aluhlaza anqunywe osayizi abadingekayo futhi ahanjiswe ngamapayipi etafuleni elifanele, lapho ezinye zezakhi zihlanganiswa ndawonye (I.E. zixhunywe okwesikhashana). Umhlangano ongaphansi ophumelelayo (ingxenye yepayipi lokugcina lepayipi) uyaqhubeka nokusebenza kwe-welding (i.e. exhunywe ngokuphelele) ngaphambi kokuthi ibuyele etafuleni elifanele futhi lilinganiswe nezinye izingxenye ze-spool.
Amapayipi ensimbi abuye abhekiswe njengezakhi ezenziwa kabusha zohlelo lwamapulangwe anjengamapayipi, ama-flanges kanye nokufakwa kwamapayipi, futhi afakwa ngesikhathi sokuthuthuka ngaphambi kokuwathumela ekwenzeni.
Lokhu kuxhumana kufakwa ngaphakathi kwezindonga zikakhonkolo ngaphambi kokuthululwa kokhonkolo. Lolu hlelo kumele luhambisane kahle ngaphambi kokuthulula ukhonkolo ngoba ludinga ukumelana nesisindo namandla wesakhiwo.
Ukungezwa kwethusi kuleli banga kukunikeza ukumelana okungcono kokugqwala kune-Chromium-Nickel Steel engenacala, ikakhulukazi ngokumelene ne-Sulfuric, phosphoric kanye ne-acetic acids. Kodwa-ke, ukusetshenziswa kwe-hydrochloric acid kukhawulelwe.
Amapayipi amapayipi avame ukusetshenziswa ezinhlakeni zikakhonkolo ukuze aqiniseke ukuthi ukufakwa okudingekayo kusendaweni ngaphambi kokuthulula ukhonkolo ekwakhiweni.
Inokumelana kahle nokugqwala kokuhlangana kwezingalo ngemuva kokuchayeka kumazinga okushisa asezingeni le-Chromium Carbide Preiptitupation uhla lwe-800 ¨c 1500¡Ãf (427 ¨c 816¡Ãc (427 ¨c 816¡Ãc (427 ¨c 81¡¡Ãc).?
Sikhiqiza kahle imikhiqizo yamapayipi. Lapho amakhasimende edinga izinto ezahlukene zihlanganiswe ndawonye ngaphambi kokufakwa, ukusetshenziswa kwezinto ezisetshenzisiwe ndawonye zibizwa ngokuthi amapayipi application. Kukhona imikhiqizo yepayipi yensimbi engenasici kanye nezinye izinto ezenziwe ngezinto ezisetshenzisiwe.
Amabanga amabili ajwayelekile ensimbi ajwayelekile angama-304 no-316. Umehluko omkhulu ukufakwa kwe-molybdenum, i-alloy ethuthukisa kakhulu ukumelana nokukhulisa, ikakhulukazi ezindaweni ezinosawoti noma nge-chloride.
I-904L I-Steressless yensimbi ayifani nanoma iyiphi enye insimbi. Ngenxa yamanani angeziwe angeziwe we-chromium, i-molybdenum, i-nickel ne-zethusi, insimbi engu-904l ifaka ukumelana okuphezulu kokugqwala, ukugqwala kanye nama-acid.
Kunamabanga ahlukene wezinto ezibonakalayo asetshenziselwa ukukhiqiza lezi zinhlaka. Insimbi engama-304 engenasici ibanga elisetshenziswa kakhulu. Insimbi engapheli yensimbi engama-304 ye-trib ye-Trib yenziwe yakhiwe ngalezi zinto futhi ine-3 clamp ifakwe lula ikhasimende. Siphinde futhi sinikeze izixazululo zangokwezifiso kumakhasimende ethu. Sicela uxhumane nathi ngezidingo zakho.
I-304 Insimbi Engagqwali yindlela evame kakhulu yensimbi engagqwali emhlabeni ngenxa yokumelana nokuqina kwayo okuhle kakhulu nokubaluleka. Ine-16% kuya ku-24% i-chromium futhi ifike ku-35% nickel, kanye namanani amancane e-carbon naku-manganese.
