304 310s 347 chitsulo chosapanga dzimbiri cham'madzi choyenerera

B16.11

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

Gulu la kalasi 316 lamphamvu limatha kugwira ntchito bwino, ndi njira zoyenera zitsulo zogwirira ntchito, kupatula kuti sizingakhale zodulidwa kwa oxygen. Kudula kwa plasma ndikwabwino. Kulephera kwakukulu kwa giredi 316 ndikopambana, chifukwa cha kukhazikika kwake kwa Austenite.

Chotupa ndi chinthu chosinthika chomwe chimalola kusintha mayendedwe mu dongosolo la masipi. Thambo limagawidwa m'magulu awiri a radius yayitali komanso radius yafupifupi, yomwe imatha kusinthidwa ndi madigiri 45, madigiri 90 ndi madigiri 180. Ma weleble amatha kukhala otchulidwa pamtunda, omwe amasintha kuwongolera kuchokera pakati pa gawo lotsutsana ndi gawo la chinthucho. Chotchedwanso pakati. Moyang'anani pakatikati pa ma radius kutalika kwa ma radius ndi 1.1 \ / 2 x nominal chitoliro chochepa, pomwe kwa radius yochepa kwambiri imakhala yofanana ndi kukula kwa Nomwenal.

Zovala zathu za SS 310s chitumbuzi zimapangidwa ndi chitsulo chochepa cha kaboni chotsika kuti chitha kuwononga chimbudzi, makamaka chiwonongeko chamadzi ndikuwongolera m'magulu a mankhwala ndi ore.

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.

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).

Zovala zasayansi 600 zimapangidwa kuchokera ku almoy-chromial-cromin inckel ndi 14% chromium yocheperako ndi 14% chromium mu kaboni, manganese, silicon, mkuwa ndi chitsulo.

Kuchepetsa kumalola kusintha kwa kukula kwa chitoliro kuti mukwaniritse zofunika kuchita kapena kuzolowera kuti mupange malo omwe alipo. Kutalika kwa kuchepetsedwa kumakhala kofanana ndi pafupifupi magawo a zitoliro zazikulu komanso zazing'ono. Kuchepetsa kumakhala kovuta, koma ma eccentric kumatha kugwiritsidwa ntchito kukhala ndi chitoliro chomwecho kapena pansi pa chitoliro.

Alinso ndi zipinda zothandiza zopangira malo osiyanasiyana ndi kutentha kwambiri. Kugonjetsedwa ndi kupsinjika kwa chloride kuwononga. Sankhani nthawi zonse kuti muchepetse mavuto osokoneza bongo. Ndikwabwino kukana chimbudzi cha sulufuric acid.

ASME A234 Wp9 Steel Pipe Mapaipi amatanthauza zokutira zomwe zili mu ASTM A234 WP9, amagwiritsidwa ntchito ngati masitepe a mafakitale am'maluwa.

Zitsulo zosapanga dzimbiri za ASM A403 WP316L zoyenerera zimatha kukhala zowoneka bwino komanso zowuma ndi ntchito yozizira. Zosapanga dzimbiri ASMEM A403 WP316L Kuyenerera kumatha kupirira ntchito yokhala ndi nitric ndi phosphoric acid ndi oxidation.

Kuphatikiza uku kumapangitsa kugonjetsedwa ndi zinthuzo ndi kutentha kwambiri mpaka 889 digiri Celsius. 304 Chitsulo Chopanda Chitsulo Chowonda Malipiro Amakumana ndi ASME A403 ndipo akupezeka kunja kwa diameters? " mpaka 48.

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.

Pofala mu makampani opukutira, zokutira zopindika ndi kulumikizana kwapata kwa chipata kumawonjezera ndikukhazikitsa kutalika kwa chitoliro.

S31254 ndi chinthu chovomerezeka ndi anti-Colussion Endost, kachulukidwe kake ndi 8.0g \ / cm3, ndipo malo osungunuka ndi 1320-130íem. Zovala zazitali za molybdenum ndi chromium ndi nayitrogeni zimapangitsa kuti zikhale zosagwirizana bwino kwambiri ndikukhotakhota. Kuphatikiza kwa mkuwa kumapangitsa kuti kutsutsana ndi kuwonongeka kwa macitidi ena. Kuphatikiza apo, kulibe mutu31254 kumakhala ndi kukana kwabwino kuphwanya chifukwa cha zomwe zili mu nickel ndi chromium ndi molbdenum zomwe zili.

Ndife tokha chitsulo chosapanga chitsulo chosapanga, duplex 2507 chipongwe, chitsulo chosapanga dzimbiri choyenerera masitepe opanga ma £. Izi zimatchedwa Duptux (kapena Austetic-Ferritic) chifukwa ma zitsulo omwe ali ndi magawo awiri, austete (cubic cubic cubic) ndi Ferrite (Thupi la Thupi Lofanana) mokwanira. Amapangidwa kuti athe kukana bwino, makamaka chloride mopsinjika kudontho ndi chloride polosera.

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.

Chitoliro chowoneka bwino chimapangidwa kuti chiwongoledwe patsamba kumapeto kwake

Giredi 310 ndi chitsulo chosapanga dzimbiri chogwiritsidwa ntchito kutentha kwambiri pamapulogalamu monga zigawo za ntchentche ndi kutentha kotentha. Imagwiritsidwa ntchito pogwira ntchito mpaka 1150¡c ndi intermittent adagwira ntchito pa 1035¡c. Gulu la 310s ndi mtundu wa kaboni wotsika wa 310 kalasi. Zitsulo zosapanga dzimbiri zili ndi zokambirana za oxidid ndipo zitha kugwiritsidwa ntchito mosalekeza pang'onopang'ono mpaka kulibe mpweya wa sulufule. Ndi chromium yomwe ili pachimake, zitsulo zosapanga dzimbiri zimakhala ndi chipongwe chabwino chomwe chimagwiritsidwa ntchito kutentha kwambiri.

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