Insimbi engagqwali

Imidwebo yepayipi engu-347 ne-spool yokuzwakala kanye nokugqwala kwezinto ezithinta izinkinga

Okuhlukile, noma kunjalo, ama-acid axidizing axidizings a njenge-nitric acid. Ama-alloys aqukethe i-molybdenum ngokuvamile awenzi kahle kulezi zindawo.?

I-Alloy 317L inokuphikiswa okuhle kakhulu kokugqwala ngamakhemikhali ahlukahlukene. Imelana nokuhlaselwa ku-sulfuric acid, i-chlorine ye-acidic ne-phosphoric acid.

Yakhelwe ukumelana nokuvuselelwa okuthuthukile kanye namandla aphezulu emazingeni okushisa angenhla kwe-1000¡Ãf (537¡Ãc).

I-Chromium, i-molybdenum, i-nickel ne-nitrogen bonke abanikela ngokumelana nakancane ekugcekeni yimidiya ehlukahlukene

Ingafakwa kalula futhi icutshungulwe yimikhuba yokuqamba ye-stack shop evamile.

I-Chromium yi-ejenti eyinhloko yokuhambisa ukumelana nokugqwala ezindaweni ezingathathi hlangothi noma ezi-oxidizing.

U-IS31254 uvame ukubizwa ngokuthi yi-¡° 6% moly¡ ± ibanga ngenxa yokuqukethwe kwe-molybdenum.

Ngokungezwa kwe-nitrogen njenge-ejenti eqinisayo, i-alloy ingaba nesiqinisekiso esimbili njengo-Alloy 317 (ama-S31700).

I-AL6XN PREPAGRICITICICITICITICITIC PIPING Systems Ukumelana Ne-Chloride Pitting

I-316l, nokho, ukukhetha okungcono kwephrojekthi edinga ukufudumala okuningi ngoba i-316 itholakala kalula ekuwohlokeni kwamandla ku-316L (ukugqwala ngaphakathi kweWeld).

Alloy 347 Iplate yensimbi engenasici ibonisa ukumelana nokuqina okujwayelekile okuqhathaniswa no-304.

I-254 SMO Pipe Fanzication Amandla Aseduze okuphindwe kabili kwe-300 Series Steel engenacala

Umndeni weMoly unekhono lokumelana namazinga okushisa aphezulu futhi alondoloze amandla ngaphansi kwezimo eziguqukayo.

Leli banga ledlule inhloso yalo lasekuqaleni futhi lifakwe ezimbonini eziningi ezifakazela ngenxa yezinga eliphakeme le-molybderum inani ezinye izinto eziphathelene nezinsiza ezihlukile njengokuphelelwa yigesi kwe-flue kanye nezindawo zamakhemikhali.

I-317 amapayipi spools ephakeme chloride chloride pittipt kanye ukumelana nokugqwala okujwayelekile

? Ukuqukethwe okuphansi kwekhabhoni ye-alloy 317l kukuvumela ukuthi kufakwe i-weld ngaphandle kokugqwala okuvela ekugxoliseni kwe-chromium carbide ukukwenza kube lula ukusetha isehlakalo se-as-welded.

Okwezinhlelo ezithile, ibanga le-grade 254 SMO kubikwe ukuthi libambela imali esebenza ngempumelelo ye-Nickel neTitanium Alloys.

I-316L ifana kakhulu ne-316 cishe ngazo zonke izindlela.?

I-Chromium, i-molybdenum ne-nitrogen kukhulisa ukumelana nokugqwala okukhonkotha. I-nickel ifaka isakhiwo se-auntenitic.

Kuklanyelwe ukuhlanganiswa kobunzima bokuqina kobunzima bokugqwala kwe-chloride ukuqhekeka kokuqhekeka, kanye nokugqwala okukhohlisayo kanye nokugqwala kwamandla ngamandla okuphindwe kabili kochungechunge lwensimbi engama-300.

I-Al6xn isetshenziselwa ikakhulukazi ukumelana nokugqwala kwayo okuthuthukile kanye ne-crevice in clorides. Kuyinsimbi enobunzima futhi engakhathali.

I-AL6XN inamandla amakhulu ashubile kunezinto ezivamile ze-austentitic, ngenkathi zigcina i-decticity ephezulu kanye namandla omthelela.

I-Alloy 254 SMO ukuphela okuphezulu, i-molybdenum ne-nitrogen allOred Super Auntenitic insimbi engenacala ngokuqukethwe okuphansi kwekhabhoni.

Insimbi engu-316 inensimbi engagqwali inekhabhoni eningi kuyo kune-316l. Lokhu kulula ukukhumbula, njengoba i-L imile "ephansi."

I-316l nayo yensimbi enhle engabi nesiqhingi ekushiseni okuphezulu, ukusetshenziswa okuphezulu kokugqwala, yingakho kudumile kakhulu ukusetshenziswa ekwakhiweni kwezokwakha nasezandleni zasolwandle.

Ipuleti lensimbi engu-alloy 347 alisebenzi kahle ngokwelashwa kokushisa, kuphela ngokusebenza kubanda.

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.

Ine-nickel ephezulu (24%), i-molybdenum (6.3%), i-nitrogen kanye nokuqukethwe kwe-chromium okunikeza ukumelana kahle nokuqhekeka kokugqwala kwe-chloride, i-chloride ukumelana, kanye nokuphikiswa okujwayelekile kokugqwala.

I-304 insimbi engagqwali inobuthakathaka obunye: Itholakala ekugculweni okuvela kwizixazululo ze-chloride noma ezindaweni zesawoti ezifana nogu.
