304 Madzi osapanga dzimangira kumatenthetsa chitoliro gasi loyenera 316 mkati ndi kunja

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

304 Imaphimba muyezo wopangira chitsulo chosapanga chitsulo chosapanga chitsulo chosakanikirana. Zinthu za zoukira chitoliro zidzaphatikizanso ku East, mipiringidzo kapena mbale yopanda nsapato kapena yosalala. Kukhululuka kapena kupanga magwiridwe antchito kudzachitika kutonthoza, kukanikiza, kuboola, kumachotsa, kugundana, kumangirirani, kapena kuphatikiza kwa ntchito ziwiri izi. Zipangizo zonse ziyenera kukhala kutentha.

Ndi kuwonjezera kwa mawonekedwe a Niobichi osapanga dzimbiri cha NNR 1.4401, zoyenerera zimakhazikika motsutsana ndi kuphatikizika kwamkati ndi komwe kumachitika. Zimalepheretsanso kufesa mkati mwa malo owala. Itha kukhalanso yotentha pogwiritsa ntchito isofce yofunikira kuti ikhale yotentha. Ili ndi nyumba yodziwika bwino ya chilengedwe chilichonse ndi kutentha kwapamwamba. Zinthu zamkuwa zomwe zili mu zolimba zimawateteza ku sulfuric acid.

Zovala zowala zolumikizira kulumikizana ndi chitoliro kuti ibweretse mpweya, madzi, mpweya wachilengedwe, ndi mafuta mu mapulogalamu ndi chakudya ndi mkaka. DZIKO LAPANSI (BW) Zoyenera kupanga zolumikizira chitoliro ndi mphamvu, kutopa, kupewetsa kutentha, komanso kutsatira kutentha.

Zitsulo zosapanga dzimbiri monga momwe zinthu zimagwiritsidwira ntchito popanga zinthu zosiyanasiyana kuchokera kumapaipi kupita kumayiko ndi zigawo zomwe zimapangidwa kamodzi ndi chitsulo chosapanga dzimbiri. Ili ndi chingwe cha radius lalitali, kuchepa kwa kusiyana, komanso kuchepa kwa eccer. Ndi gawo lofunikira m'makina opangira mafakitale omwe amathandizira kusintha mapaipi.

MSS-SP43 Yaitali ya Rius, wowongoka mtima, lowongoka, lopindika, ma radius okwera, 1 \ 2 "-24" schxxs

Zomwe timapereka 904l Budweld erbow ili ndi chitsulo chotsika champhamvu cha ma carbon ndi cromium

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.

Chipata chosapanga dzimbiri 304 chitoliro cha 304l chitoliro chimapangidwa pakutsatira anyezi A403 ndi ANA B16.9

Ndife ogulitsa ndife opanga chitoliro, zolengedwa zachitsulo zosapanga dzimbiri, zosapanga dzimbiri zosapanga, chitsulo chosapanga dzimbiri, chitsulo chosapanga dzimbiri 310 Chitoliro cha chitoliro, chitsulo chosapanga dzimbiri cha 316 chitoliro, chosapanga dzimbiri cha 316l chitoliro chokhazikika, chitsulo chosapanga dzimbiri 321 chipika

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.

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.

Zitsulo zosapanga dzimbiri ndi banja la zitsulo zosapanga dzimbiri. 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. Adapangidwa kuti athe kukana bwino, makamaka chloride mopsinjika chipongwe ndi chloride pansi kutukula, komanso kulimba kwambiri kuposa zitsulo zosapanga dzimbiri monga 30 kapena 316.

Zithunzi zopendekera nthawi zambiri zimagwiritsidwa ntchito m'njira zosiyanasiyana zaulimi ndi mafakitale. Mankhwala a mankhwala, mafakitale a petrochemical, zamkati, ndi zomera zopangira pepala, zowonjezera, zotayika, kutaya zinyalala kapena kuwononga zinyalala.

Alloy X chitoliro chotsitsidwa chimadziwika kuti mphamvu zake zimakhala bwino kwambiri zamphamvu kwambiri mpaka 2200¡f. Alloy imathanso kukhala yopangidwa mosavuta ndikupanga ndi kuwotzera mawonekedwe ndi njira zonse ziwiri komanso njira zokha.

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).

Pamene titanium imasakanikirana ndi zitsulo zina, oyang'anira amathanso kukhala ndi mphamvu yayikulu yoposa 1,400 MPA, yomwe imapanga 200,000 psi.

Zovala zosapanga dzimbiri 316 zachitsulo 316 zokhala ndi malonda omwe amapangidwa ndi kalasi 316. Amatchedwanso Bine kalasi. Akuluwa S31600 SS amanenedwa kuti ali ndi magetsi ndi kuponderezedwa ndi magiredi ena osapanga dzimbiri. Ngakhale zitsulo zosapanga dzimbiri nthawi zambiri zimatchedwa chitsulo, ndi nickeum ndi chromium ndi chromium madonthos a SP303 SS Slub ali ndi Molybdenum omwe ali ndi Molybdenum wowonjezerapo kuti athe kuthana ndi vuto lake.

Izi zowoneka bwino 90 zowoneka bwino zimapangidwa kuti zizilekerera kwambiri kudzera pa hydroformeng. Zotsatira za hydroformarming zimabweretsa yunifolomu yofanana ndi yosavuta kutchetcha ndi kupopera. Njira yopanga iyi imatipatsa mwayi wopereka zabwino kwambiri mosasamala kanthu za ntchitoyo. Oyenera kugwiritsa ntchito ntchito kuyambira pa chakudya ndi chakumwa, mkaka, ndi mankhwala osokoneza bongo ndi oyendetsa.

Zoyenera za N10276 zimakhala ndi mphamvu zapamwamba ngakhale kutentha kwambiri ndikuwonetsa ntchito yabwino pansi. Mphamvu ya Astm B366 SI10276 Tsitsi ndi pafupifupi 105.4 ksi.the.am. B366 WFC276 imapangidwa mosavuta ndi kuzizira. Ngakhale kuchepa kwa WFCC2776 kungakhale kotentha, njirayi iyenera kuchitika ndi magawo ena

Chizindikiro cha Nickel-Copper chimakhala chouma chifukwa chowonjezera aluminiyamu ndi titanium. Imaphatikiza kukana kwa Monl 400 ndi phindu lopeza lamphamvu kwambiri ndi kuuma (kuchokera ku zovuta zake). Monl K-500 imadziwikanso kuti nsalu ya nsalu yoyerekeza poyerekeza ndi ena a superralos, ndipo kwenikweni kuti ndi madzi osalala ngakhale kutentha pang'ono.

ASTM A420 ndiye lingaliro lokhazikika la zoukira za chitoliro za chitsulo cha mkaka chambiri komanso chachitsulo cha ntchito yotsika kutentha. Zoyenera izi, kaya ka zomangamanga zosasaka kapena zowoneka bwino, zimagwiritsidwa ntchito makamaka pakukakamizidwa ndi ntchito yochepa ya kutentha pang'ono. Metals-Pippop imatha kupereka ma grade onse achitsulo okutidwa ndi Astm A420: WPL6, WPL9, WPL3, ndi WPL8.

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

1.4404 Sa403 WP316L ERIBO siyofunikira. Chifukwa cha kukana kwawo kwabwino kwambiri ku Controsion kwa Internasion, zoyengerera izi zitha kugwiritsidwanso ntchito m'malo owotcha. Kuzizira Kugwiritsa ntchito Althor sikungakulitse mphamvu ndi kuuma kwa anyezi A403 WP316L Fritings, koma zingawapangitsenso maginito pang'ono.

Zithunzi zopendekera nthawi zambiri zimagwiritsidwa ntchito m'njira zosiyanasiyana zaulimi ndi mafakitale. Mankhwala a mankhwala, mafakitale a petrochemical, zamkati, ndi zomera zopangira pepala, zowonjezera, zotayika, kutaya zinyalala kapena kuwononga zinyalala.
