Chitsulo chosapanga dzimbiri cha A403 WP316L ELbow LR

Ma SD Rowrs adapangidwa kuti athetse kukana, kutopa kwambiri, kukokoloka kwa kukokoloka, SCC, Crevice kuturuka komanso luso labwino. SD Cross imaphatikiza ducticle, mphamvu yayikulu ndi kukana kwa m'mlengalenga.

Chifukwa chowonjezera chromium, osakwana N08800 Tsamba lolemba sagwirizana ndi maxidive media monga Nitric Acid, Mchere ndi Nitrate. Izi za Anoy 800ht Malekezero amatha kupirira kutentha kwambiri madera ndipo ali ndi mawonekedwe abwino.

Kukana kwa Suftelluy ku Sulfuric acid kumapangitsa kuti ikhale chisankho wamba chitetezo ku hydrogen sulfide (h2s), imadziwika kwambiri.

Ubwino wa zitsulo zosaphika dzimbiri - zotsekerera zomaliza zopepuka zimaphatikizapo kupewa kwamuyaya, mphamvu zowonjezereka za pasitepe, ndikuchepetsa kutaya kwa nsalu, koma chipewa chakhungu chimakhazikika ngati wakhungu.

Kukhalapo kwa gawo la sigma mu S31803 AsBofeser Alboy akuvulaza chifukwa chokana chifukwa chakuti, kumachepetsa katundu wazinthu monga kusokoneza.

Gulu lopanga dzimbiri 317l ndi mtundu wotsika wa kaboni ka 317, chitsulo chosapanga dzimbiri 317 \ /

Zitsulo zosapanga dzimbiri ndi chitsulo chomwe chimalimbana ndi dzimbiri. Ili ndi 11% chromium ndipo imatha kukhala ndi zinthu monga kaboni, zina zosakhala ndi zitsulo zina kuti mupeze zomwe akufuna. Kutsutsa kopanda dzimbiri kuti chiwonongeke kumabweretsa chifukwa cha chromium, omwe amapanga kanema wongokhala womwe umatha kuteteza nkhaniyo ndikuchira pamaso pa mpweya.

The S31803 (ASTM F51) imathamangitsidwa kwambiri ndi S32205 (1.4462, Astm F60). Izi zikuwonetsa chikhumbo chawo chokulitsa zachilengedwe za Aloy Kuphatikiza apo, zimalola kukopa gawo la nayitrogeni osati kungokhala ngati chinthu choyambira. Therefore, the highest performing duplex grades seek to maximize the content of chromium (Cr), molybdenum (Mo) and nitrogen (N).

Incloy 800, 800h, ndi 800ht ndi Nickel-Chromial-Chromium imayendetsa bwino ndi mphamvu yabwino kwa oxidation ndi kusamala kwambiri.

Pofuna kufafanizira mapaipi, ndikofunikira kuchotsa payipi yolunjika pa mapaipi. Mukamagwiritsa ntchito ma piipelines osiyanasiyana, mapaipi osiyanasiyana ayenera kugwiritsidwa ntchito. Pamene mapaipiwo amagwiritsidwa ntchito, chikopa chiyenera kugwiritsidwa ntchito kusintha kukula kwa mapaipi. Mukamacheza, chipika chanjira zitatu chowonekacho chimagwiritsidwa ntchito ngati cholumikizira cholumikizira, kuti chikhazikitse chipani cholumikizirana kapena kukula kwa nthawi yayitali komanso cholumikizira cholumikizira cha mapaipi. , Pakulumikizana ndi zida zosiyanasiyana, palinso zolumikizira ndi mapulagini a gawo la chida.

Kwa mapulogalamu ogwiritsa ntchito pepala amafuna magiredi a Anoy omwe alibe zokwanira kuwonongeka. Kutengera ndi zikhalidwe 22%, ali ndi austetitic: microptuction microstructuctunce yomwe imapereka mphamvu zazikulu, kukana ndi kuchuluka kwa mtengo wake.

ASTM A815 S3205 S3205 Kutalika kwa ma rabow kumagwiritsidwa ntchito potembenukira kutsogoza mapaipi ndipo amagonjetsedwanso chloride ndi mabwinja a Sulfide. Asme B16.9 Duplex kapangidwe ka chitsulo chosapanga chitsulo chopanda kanthu zimakhala ndi zolaula zapamwamba.

S31803 ndiye njira yolumikizirana yolumikizidwa (yopanda tanthauzo) ya chitsulo choyambirira. Dongosolo la Unili lidapangidwa ndi magulu ambiri amalonda m'ma 1970 kuti muchepetse chisokonezo pomwe alloyo yemwe yemweyo adatchedwa zinthu zosiyanasiyana, komanso mosemphanitsa. Chitsulo chilichonse chimayimiridwa ndi kalata yotsatiridwa ndi manambala asanu, pomwe kalatayo ikuyimira zitsulo, i.I. s ya chitsulo chosapanga dzimbiri.

800h amatha kukana kufesa kwa nkhani zambiri zowononga. Zolemba zake zapamwamba zimapangitsa kuthana ndi kupsinjika kuwononga mikhalidwe yotupa. Zovala zazitali za chromium zimaperekanso kukana kwabwino kuti tisunthe komanso kupindika. Alloy ali ndi vuto labwino ku Nitric acid ndi organic acid, koma kutsika pang'ono ku sulufuric acid ndi hydrochloric acid. Kutsutsa kwabwino kwa mchere wosalala komanso wopanda mchere, kuwonjezera pa zomwe zingatheke kuwononga. Ilinso ndi kukana bwino m'madzi, nthunzi ndi zosakanizira za nthunzi, mpweya ndi mpweya woipa.
Zingwe za Aloy 825 zopota ndi zigawo zopangidwa kuti zikhale ndi zowonjezera za chromium, nickel ndi chitsulo ndi zowonjezera ndi zowonjezera za Molybdenum, Titanium ndi mkuwa. Zovala zopserezi m'mitundu iyi zimakhala ndi ulusi womwe umagwirizana ndi ulusi wa gawo la chitoliro. Izi zimawathandiza kuti azitetezedwa mosavuta mpaka zingwe za misonkhano ya zipuile yotsatira. Lumikizani mwachikondi kukwaniritsa msonkhano; Komabe, mu ntchito zina zoyenerera izi zitha kuphatikizidwa mosavuta. Kugulitsa msonkhano sikulimbikitsidwa, monga zolumikizira zopindika zomwe zasindikizidwa kale kumatha kukulira kutentha chifukwa cha kutentha kwa matcheru.

Asme B16.9 Kutalika Kwakale, Radius Wautali Kubwezeretsa Malekezero, Rius Longlers, Mitambo Yolunjika, Mitambo Yolunjika, 1 \ 2 "-48" Khoma makulidwe: Sch5s-Schxxs

Ndife kampani yokhala ndi zaka 50 zokumana nazo muzosapanga dzimbiri zopanga zowonjezera. Kusungitsa mwadzidzidzi kwadzidzidzi kumapangitsa zinthu zina ndi zinthu zina zomwe zimapangidwa kuchokera ku zinthu zapamwamba komanso macheke okhazikika pamagawo onse opanga kuti awonetsetse kuti akhale abwino.

Kenako kuyenera kukhala gawo la kachitidwe koyendetsa madzi (mafuta, gasi, nthunzi, macheza, ...) mtunda wautali kapena wautali.

FOSTELOLELOY B2 chitoto chawuma chimakankhira mapangidwe a chimanga cha chimanga cham'madzi chofiyira, ndikupangitsa kukhala koyenera kwa ntchito zamankhwala ambiri mu mkhalidwe wa mankhwalawo.

Duptux Steel 2101 Fuss Stud Top, yomwe ndi yogwiritsidwa ntchito kwambiri (modabwitsa & austetitic kwambiri)

Mchere uwu umatha kudwala pomwe hydrochloric acid amakumana ndi chitsulo ndi mkuwa. Chifukwa chake, ngati alloy uyu amagwiritsidwa ntchito molumikizana ndi chitsulo kapena mkuwa mu dongosolo lomwe lili ndi hydrochloric acid, kukhalapo kwa mcherewu kumatha kuyambitsa chisanakwa.

Mapulogalamu achitsulo osapanga dzimbiri ndi chinthu chosankha chonyamula madzi otchinga kapena udzi, ma slorries ndi mipweya yambiri, kutentha kwambiri kapena matupi obiriwira omwe akukhudzidwa. Chifukwa cha zokongoletsa za chitsulo chosapanga dzimbiri, chitoliro nthawi zambiri chimagwiritsidwa ntchito pogwiritsa ntchito zomangamanga.

Kuletsa kuwonongeka ndikusokoneza kutentha kwambiri, gawo lambiri s31803 \ / s32205 chimakhala chopambana pazigawo zamankhwala zomwe zimatha kuwonongeka ku chloride. Ndi makina osokoneza bongo.

FOSTELOLELOY B2 chitoliro chimakhala chowongolera kwambiri kuti muchepetse kuwononga chipongwe ndi kupsinjika komwe kumachitika

Chitoliro chowoneka bwino chimapangidwa kuti chijambulidwe patsamba kumapeto kwake ndikulumikizani mapaipe (s) ndikulola kusintha njira kapena kuthirira kapena kutha.

Chiwonetsero cha nickel ndi chotsimikizika chawiri (800h \ / ht) ndikuphatikiza zomwe zimapangidwa ndi mitundu yonseyi. Incluoy 800h \ / ht alloy adapangidwa kuti azitha kutentha kwambiri.

Astme A234 imaphimba zitsulo za kaboni wa kaboni pang'ono komanso zomangamanga zaposachedwa kwambiri za ASME B16.9, B16.11, SS-73, ndi MSS-95, 97.

Pakadali pano zokhala ndi chitolirochi zikukhudzidwa, kuthamanga komweko ndi kuthamanga kumatheka ndi chitsulo chosapanga dzimbiri chomaliza.
