Ubwino Waukulu wa Incoloy 825

Kukana Kwambiri kwa Acid– Incoloy 825 imapereka kukana kwakukulu kwa sulfuric, phosphoric, ndi nitric acids pamlingo waukulu komanso kutentha. Kuphatikiza kwa nickel, chromium, molybdenum, ndi mkuwa kumapanga zinthu zomwe zimakana kuchepetsa komanso kuwononga asidi. Mu sulfuric acid mpaka 40% pa 100°C, chiŵerengero cha dzimbiri chimakhala chochepera 0.5 mm pachaka.

Kukana Kudzikundikira ndi Kupasuka kwa Mng'alu– Kuchuluka kwa molybdenum (2.5-3.5%) kumapereka kukana bwino kwambiri ku dzimbiri la dzenje ndi ming'alu m'malo okhala ndi chloride. Mtengo wa PREN wa pafupifupi 36 umatsimikizira magwiridwe antchito odalirika m'madzi a m'nyanja ndi mitsinje yokhala ndi chloride yambiri komwe chitsulo chosapanga dzimbiri cha 316L chingalephereke.

Kupsinjika kwa Dzimbiri Kukaniza Kupsinjika– Kuchuluka kwa nickel (38-46%) kumapereka kukana kwakukulu ku ming'alu ya dzimbiri yomwe imabwera chifukwa cha chloride. Incoloy 825 imatetezedwa kwambiri ku SCC m'madzi a m'nyanja, kupopera mchere, ndi malo okhala ndi chloride komwe zitsulo zosapanga dzimbiri za 304/316 nthawi zambiri zimalephera.

Kukhazikika kwa Titaniyamu– Kuwonjezera titaniyamu (0.6-1.2%) kumalimbitsa alloy motsutsana ndi dzimbiri la pakati pa tinthu tating'onoting'ono. Mwa kupanga TiC ndi TiN precipitates zokhazikika, titaniyamu imaletsa kupangika kwa chromium carbides pamalire a tirigu panthawi yowotcherera, kuonetsetsa kuti dzimbiri silikulimba m'dera lomwe lakhudzidwa ndi kutentha.

Kutha Kusenda Bwino Kwambiri– Incoloy 825 ikhoza kulumikizidwa pogwiritsa ntchito TIG, MIG, resistance welding, ndi njira zina zokhazikika. Kufanizira filler metal ERNiFeCr-1 (AWS A5.14) kumalimbikitsidwa pa ntchito zomwe zimafuna chemistry yofanana. Nthawi zambiri sikufunika kutentha koyambirira, ndipo chithandizo cha kutentha pambuyo pa weld sichifunikira pa ntchito zambiri.

Katundu Wabwino wa Makina– Chitsulochi chimasunga mphamvu zabwino zamakina kuyambira kutentha kwa cryogenic mpaka -184°C mpaka 538°C (1000°F). Kugwira ntchito mozizira kumawonjezera mphamvu (mpaka 1,035 MPa) pamene kuli koyenera kusinthasintha.

Kutsatira NACE MR0175 / ISO 15156– Incoloy 825 ndi yoyenera kugwiritsidwa ntchito mumakampani opanga mafuta ndi gasi, polimbana ndi kusweka kwa sulfide stress (SSC) ndi kusweka kwa hydrogen (HIC) m'malo okhala ndi H₂S.

Kugwiritsa ntchito kwa Incoloy 825

Kukonza Mankhwala– Incoloy 825 imagwiritsidwa ntchito kwambiri mu zomera za sulfuric acid, phosphoric acid, ndi nitric acid. Ntchito zake zimaphatikizapo zosinthira kutentha, zipilala zotulutsira, matanki osakanizira, mapaipi, mapampu, ndi ma valve omwe amagwira mitsinje ya asidi wowononga. Kuchuluka kwa mkuwa mu alloy kumapereka kukana kwakukulu ku sulfuric acid pamitundu yosiyanasiyana.

Mafuta ndi Gasi– Incoloy 825 yapangidwa kuti igwiritsidwe ntchito pa zipangizo zopangira mafuta ndi gasi, kuphatikizapo mapaipi olowera pansi, zida zoyambira pansi pa madzi, mitengo ya pansi pa nyanja, mizere yoyenda, ndi zinthu zina zopangira. Kutsatira kwake NACE MR0175 / ISO 15156 kumatsimikizira kuti zinthu zikuyenda bwino m'malo okhala ndi H₂S. Chosakanizachi chimagwiritsidwanso ntchito pamizere yopangira mankhwala ndi zida za nsanja yakunja.

Kupanga Mphamvu za Nyukiliya– Incoloy 825 imagwiritsidwa ntchito m'mafakitale okonzanso mafuta a nyukiliya, makina osungira mafuta ogwiritsidwa ntchito, komanso m'malo oyeretsera zinyalala za radioactive. Kukana kwake ku nitric acid ndi radiation kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito motere.

Uinjiniya wa Zam'madzi- Chitsulochi chimagwiritsidwa ntchito popaira madzi a m'nyanja, zida zochotsera mchere m'madzi, ndi zida zina za pa pulatifomu ya m'nyanja. Kukana kwake ku dzimbiri ndi kuphulika kwa ming'alu m'madzi a m'nyanja kumapangitsa kuti chigwiritsidwe ntchito m'nyanja komwe chitsulo chosapanga dzimbiri cha 316L sichikwanira.

Kuletsa Kuipitsa– Incoloy 825 imagwiritsidwa ntchito m'makina oyeretsera mpweya woipa (FGD), m'malo otenthetsera zinyalala, komanso m'malo osungira zinyalala zapoizoni. Kukana kwake ku mpweya wa asidi ndi condensate yowononga kumatsimikizira kuti ntchito yake ndi yayitali.

Mafunso Ofunsidwa Kawirikawiri

Q: N’chifukwa chiyani Incoloy 825 ndi chinthu chomwe chimakondedwa kwambiri pa ntchito ya sulfuric acid?

A: Kuphatikiza kwa Incoloy 825 kwa nickel, chromium, molybdenum, ndi mkuwa kumapereka kukana kwakukulu kwa sulfuric acid pamlingo wosiyanasiyana komanso kutentha. Kuwonjezera kwa mkuwa (1.5-3.0%) kumathandiza kwambiri pakukweza kukana dzimbiri pochepetsa malo okhala ndi asidi.

Q: Kodi kusiyana pakati pa Incoloy 825 ndi Inconel 625 ndi kotani?

A: Incoloy 825 ili ndi mkuwa (1.5-3.0%) woteteza kwambiri asidi wa sulfuric ndipo ndi wotsika mtengo. Inconel 625 ili ndi molybdenum wochuluka (8-10%) ndi niobium woteteza kwambiri dzenje m'madzi a m'nyanja. Sankhani 825 woteteza asidi; sankhani 625 woteteza kwambiri madzi a m'nyanja ndi malo okhala ndi chloride yambiri.

Q: Kodi Incoloy 825 ndi yoyenera kugwiritsidwa ntchito ngati sour service?

A: Inde. Incoloy 825 ndi yoyenerera kugwiritsa ntchito NACE MR0175 / ISO 15156 pa ntchito zofewa mumakampani amafuta ndi gasi, polimbana ndi kusweka kwa sulfide komanso kusweka komwe kumachitika chifukwa cha haidrojeni m'malo okhala ndi H₂S.

Q: Kodi Incoloy 825 ndi yosavuta kuiwotcherera?

A: Inde. Incoloy 825 ikhoza kulumikizidwa pogwiritsa ntchito TIG, MIG, resistance welding, ndi njira zina zokhazikika. Kufanizira filler metal ERNiFeCr-1 (AWS A5.14) kumalimbikitsidwa. Nthawi zambiri sikufunika kutentha, ndipo kutentha pambuyo pa weld sikofunikira pazinthu zambiri.

Q: Kodi kutentha kwakukulu kwa ntchito ya Incoloy 825 ndi kotani?

A: Kuteteza dzimbiri: ntchito yopitilira mpaka 538°C (1000°F). Kugwiritsa ntchito masika: mpaka 260°C (500°F). Chitsulochi chimasunga mphamvu zabwino zamakina kuyambira kutentha kwa cryogenic (-184°C) mpaka 538°C.

Q: Kodi Incoloy 825 ndi yofanana bwanji ndi ya ku China?

A: Giredi yofanana ndi ya ku China ndi NS142 (耐蚀合金). Imadziwikanso ndi dzina lake la UNS N08825 ndi nambala ya Werkstoff 2.4858.

Q: Ndi mitundu iti ya zinthu zomwe zilipo za Incoloy 825?

A: Womic Steel imapereka Incoloy 825 mu chitoliro chopanda msoko, chitoliro cholumikizidwa, bala lachitsulo, mbale yachitsulo, cholumikizira chachitsulo, mzere, ma flange, zolumikizira mapaipi, zolumikizira, waya, masipure, ndi ma valve.
