Lapho ukhetha ama-sterainless steres okufanele ubekezelele izindawo ezilonakalisayo, ama-autenitic angenazinsimbi ajwayele ukusetshenziswa.
Insimbi engu-316 inensimbi engagqwali inekhabhoni eningi kuyo kune-316L. Lokhu kulula ukukhumbula, njengoba i-L imile "ephansi."
I-alloy inokumelana ne-oxidation enhle kanye namandla aqhakazayo ku-1500¡Ãf (816¡Ãc). Iphinde futhi ibe nobunzima bokushisa okuphansi okuphansi.
Insimbi yebanga le-304 ngokuvamile libhekwa njengensimbi evame kakhulu ye-auntenitic.
Ama-Spools e-Pipe asetshenziswe kuqala ukunciphisa izindleko zokufaka insimu futhi anikeze ikhwalithi ephezulu emikhiqizweni. Ngokuvamile bavutha ukuze bathole ukuxhumana kwezinye izipikha. Ukwakheka kwe-spool kuvame ukwenziwa yizinkampani ezikhethekile ezinengqalasizinda edingekayo.
Ukuqina kwensimbi kungenye yezinzuzo ezinhle kakhulu zezinhlelo zepayipi. Kuqinile futhi kungamelana nezingcindezi, amazinga okushisa, ukushaqeka okusindayo, nokudlidliza. Iphinde ibe nokuguquguquka okuhlukile okunikezela ukunwetshwa okulula.
Okuqukethwe okuphezulu kwe-chromium kukhuthaza futhi kugcinwe ifilimu nje evikela impahla ezindaweni eziningi ezilonakalisayo.
Alloy 347h (us s3409) ipuleti yensimbi engagqwali yi-carbon ephakeme (0.04 ¨c 0.10) inguqulo ye-alloy.
I-316l PePRAB PIGE inamandla emazingeni okushisa aphakeme
Amanani aphezulu e-nickel ne-chromium e-autenitutic steress acrenless anikeza izakhiwo ezinhle kakhulu zemishini, kanye nokuphikiswa okuhle kakhulu kokugqwala.
Amapayipi ensimbi engagqwali 304 304l ngama-Flanges
I-304 insimbi engagqwali inobuthakathaka obunye: Itholakala ekugculweni okuvela kwizixazululo ze-chloride noma ezindaweni zesawoti ezifana nogu.
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.
Lezi zimboli zochwepheshe ezikhethekile zikhiqiza uhlelo ngaphansi kwesethi ebekiwe yekhwalithi nokunemba ukuze sithole kufanelekile endaweni futhi ukugcina izakhiwo zezobuchwepheshe ezidingekayo ezichazwe yiklayenti.
Ngokuhlinzekwa kwamanzi namagesi avuthayo, amapayipi ensimbi angamapayipi awusizo kakhulu. Zisetshenziswa emakhaya amaningi nakumabhizinisi ukudlulisa igesi yemvelo noma uphethiloli we-propane. Baphinde basebenzise izinhlelo zokufakelwa komlilo ngenxa yokumelana kwabo okuphezulu.
I-316l nayo yensimbi enhle engabi nesiqhingi ekushiseni okuphezulu, ukusetshenziswa okuphezulu kokugqwala, yingakho kudumile kakhulu ukusetshenziswa ekwakhiweni kwezokwakha nasezandleni zasolwandle.
Ukwakheka kwepayipi kubaluleke kakhulu ngoba ukwakhiwa komkhumbi nezinye izimboni zasemanzini zidinga amapayipi amakhulu. Amapayipi Spools adala izinzuzo ezinhle ngoba anciphisa ukulinganiselwa kwesikhala esizeni.
I-Alloy 904L ihluphuke ezinye izinsimbi ze-autenitic ezingenasici ngenxa yezinga eliphakeme lokwabiwa kwe-nickel ne-molybdenum.
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).
I-316l, nokho, ukukhetha okungcono kwephrojekthi edinga ukufudumala okuningi ngoba i-316 itholakala kalula ekuwohlokeni kwamandla ku-316L (ukugqwala ngaphakathi kweWeld).
Ama-Pipe Spool Systems asetshenziswa kakhulu ezitshalweni zamandla kanye nama-petroleum Remineries adinga amapayipi anzulu. Lezi zinhlelo zifaka ukuthwala kanye nokuthuthwa koketshezi kanye negesi futhi lezi zinhlelo zokuhamba zidinga izingxenye eziningi zokuxhuma. Kulezi zinhlelo, ayikho indawo yamaphutha.
Insimbi engenasici 904L \ 15539 impahla ingasetshenziswa ukwenza ishidi elishisayo nelibandayo, imikhiqizo eqediwe, imigoqo ye-rolled, kanye namapayipi athuliwe kanye namaphrofayili ezicelo zokucindezela.
Ngale nzuzo, yonke ipayipi esebenzisa izimboni inethuba elihle lokukhulisa ukusebenza kahle kohlelo lwepayipi futhi yehlise isidingo sabo sokusebenza nesikhathi.
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.
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).?
Imiphetho engaphezulu yezakhi kumele ibe nokungcola komhlaba kufanele kususwe. Inqubo ebhekisisa isetshenziswa emaphethelweni ezingxenye. Kuqashwa umshini wokugaya inqubo ye-Beving. Uhlobo lwemishini yokugaya ye-beveling yehluka ngezakhi zensimbi ezingagqwali nezakhi zensimbi zekhabhoni.
Amapayipi e-Spools akhiqizwa ukusetshenziswa kwamapayipi aluhlaza kanye nokufakwa kwamapayipi. Inqubo yokusika yamapayipi eluhlaza yenziwa ngosayizi wamasehlakalo ofanele ukufakwa kwamapayipi nezinye izinto.
Inqubo elandelayo ngemuva kokumaka isinyathelo sokusika. Indlela yokusika yehluka ngezinto ezahlukahlukene. Ngakho-ke, ngensimbi yekhabhoni, indlela yokusika amalangabi iyasetshenziswa. Ngaphezu kwalokho, izingxenye zensimbi ezingagqwali zingasikwa kusetshenziswa umshini wokusika we-plasma arc. Uma umsiki we-plasma arc usebenzisa ezinye izimo ezithile kufanele zigcinwe.
Inqubo efanelekile ne-welding kumele isetshenziswe ngemuva kokuqedwa kokuphela kwezingxenye. Ngakho-ke, ngensimbi engagqwali kanye ne-carbon spoile spools spools, izingxenye zingatholakala ezisekelweni zensimbi noma izisekelo zokhuni. Ngaphezu kwalokho, noma yiliphi ithuba lokuxhumana phakathi kwensimbi yekhabhoni nensimbi engenacala kufanele kuncishiswe.
I-Plasma Arc Cutter isetshenziselwa amapayipi amakhulu (ngenhla kwama-intshi angama-28 wosayizi wepayipi oyisikhonkwane) nokusetshenziswa kwayo nakho kuzuzisa ukusika amagatsha. Uma kungenzeka, icala langaphakathi kumele libe ngamapayipi noma ukufakwa, ukuze livikeleke eziswindi ezidalwe yi-plasma arc cutter. Ngemuva kokusika, nokulungiselela onqenqemeni kumele kugcinwe.
