Different kushanda tembiricha vharafu zvinhu kushandisa vharafu zvinhu Stainless simbi ndiro inopisa yakakungurutswa simbi sumo
Chimwe chezvinhu zvakakosha zvekufunga nezve dhizaini dhizaini uye kusarudzwa kwezvinhu ndiko kupisa kwekushanda kwevhavha. Uyezve simbisa tembiricha yakakodzera yekushanda kwevhavha maitiro emuviri zvinhu, kubva mukuita kwesimbi yakadzika nhamba inoshandiswa mumhando dzakasiyana dzezvivakwa zvekuvaka mavharuvhu, tembiricha yakakodzera yekushanda uye zvinoenderana nezvinodiwa zvevhavha maitiro emuviri zvinhu zvinoshandiswa mudzimba petrochemical midziyo, zvidyarwa zvemakemikari, organic fetereza, magetsi emagetsi engineering uye metallurgical indasitiri uye mamwe minda akatsanangurwa kutaridzika kwedhizaini, kugadzira uye kuyedzwa kwezvigadzirwa zvevharuvhu Hongu. Iri bepa rinonyanya kusuma zvakadzama tembiricha vharafu, inoenderera yakakwira tembiricha vharafu, corrosion resistant nickel base alloy corrosion resistant nickel base alloy valve yakasarudzwa.

Uyezve simbisa tembiricha yakakodzera yekushanda kwevhavha maitiro emuviri zvinhu, kubva mukuita kwesimbi yakadzika nhamba inoshandiswa mumhando dzakasiyana dzezvivakwa zvekuvaka mavharuvhu, tembiricha yakakodzera yekushanda uye zvinoenderana nezvinodiwa zvevhavha maitiro emuviri zvinhu zvinoshandiswa mudzimba petrochemical midziyo, zvidyarwa zvemakemikari, organic fetereza, magetsi emagetsi engineering uye metallurgical indasitiri uye mamwe minda akatsanangurwa kutaridzika kwedhizaini, kugadzira uye kuyedzwa kwezvigadzirwa zvevharuvhu Hongu. Mukuwedzera, kubva pakuona kwehutano hwehutungamiri uye hutungamiri hwekugadzirwa kwebhizimisi uye kutenga zvinhu, kune imwe neimwe simbi yakasiyana inofanira kusarudzwa nekushanda kwakazara, isingakodzeri kushandiswa kwemhando dzakawanda dzesimbi dzine nhamba yakafanana, kudzivirira kuvhiringidzika.
1. Chinhu chikuru chevharuvhu yekushisa (-254 (liquid hydrogen) ~ -101 ℃ (butadiene)) maitiro anofanira kunge ari pasi-alloy simbi, alloy material kana aluminium alloy profile ine body-centric lattice constant. Iyo yekupedzisira-yakaderera tembiricha yemuviri zvivakwa mushure mekupisa kurapwa maitiro, kunyanya iyo yekupedzisira-yakaderera tembiricha kutsemuka kuoma kunoda kusangana nezvinodiwa zveyero. Masimbi anotevera akaderera alloy anogona kushandiswa kugadzira tembiricha mavharuvhu. ASTMA351 CF8M, CF3M, CF8 uye CF3,ASTM A182F316, F316L, F304 uye F304L,ASTM A433 316, 316L, 304, 304L uye CF8D. Iyo oiri yedunhu ndiro, imwe inoyerera vharafu, gedhi vharafu kana piston vharafu yekushisa vharafu inofanira kunge iri cryogenic kurapwa mune yemvura nitrogen (-196 ℃) isati yadzika kugadzirisa.
2. Inoramba iine tembiricha yevharuvhu I-Cr-Mo inoramba iine tembiricha yesimbi yesimbi inowanzo shandiswa kusarudza WC6, WC9 uye C5 (ZG1Cr5Mo) muASTM A217 tsanangudzo, uye mahwendefa anowirirana akakungurutswa ari F11, F22 uye F5 muASTM A182.
(1) Low chromium giredhi chrome-molybdenum simbi ine WC6, WC9, F11 uye F22, svikiro rayo rinoshandiswa imvura, chiutsi uye radon gasi, haikodzere sulfuri yemafuta akacheneswa. WC6 uye F11 akakodzera kushanda tembiricha -29 ~ 540 ℃, uye WC9 uye F22 akakodzera kushanda tembiricha -29 ~ 570 ℃.
(2) C5 (ZG1Cr5Mo) uye F5 chromium pentamolybdenum yakakwirira tembiricha simbi, ayo anoshanda midhiya yemvura, utsi, radon gasi uye sulfur yemukati yemafuta akacheneswa. C5(ZG1Cr5Mo) kana yakashandiswa mumhute yemvura, tembiricha yayo yakanyanya kushanda i600 ℃. Iyo yakanyanya tembiricha yekushanda i550 ℃ kana ichishandiswa mukati senge sulfur content yakanatswa mafuta. Naizvozvo, tembiricha yekushandisa yeC5(ZG1Cr5Mo) inofanirwa kuve isingasviki 550 ℃.
3, corrosion resistant nickel base yakakwira tembiricha alloy corrosion resistant nickel base alloy valve ndiyo kiyi yekushandisa iyo ASTM A494 kutsanangurwa kweiyo forged monel alloy.
(1), cast nickel base alloy (CZ-100), Inconnel aluminium alloy (CY-40), Hastelloy alloy B(N-12MV, N-7M) uye Hastelloy C(CW-(1) Monel alloy Monel ine simba guru. uye ductibility, kunyanya yakanakisa kuramba kuderedza asidhi uye yakasimba asidhi zvinhu uye gungwa corrosion ehupfumi Naizvozvo, inowanzoshandiswa pakugadzira uye kutakura hydrochloric acid, mvura munyu, kwazvakarerekera zvinhu, alkali munyu uye oxidizing asidhi uye zvimwe midhiya midziyo uye mavharuvhu, uyewo. Yakakodzera kuoma uye manic hydrogen, hydrogen chloride gasi, 425 ℃ inoenderera tembiricha yehydrogen uye 450 ℃ inoenderera tembiricha yehydrogen chloride gasi nezvimwe zvinhu, asi hairambire zvinhu zvesarufa uye zvinoderedza (senge sodium cyanide uye zvinhu zvine oxygen. ) Kuora Ivharuvhu yezvinhu kodhi yeMonel alloy iMM, uye chikamu chikuru iMonel alloy vheruvha yekabhoni simbi iC/M, iyo vheji yemhando yeCF8 iP/M, uye vharafu zvinhu. kodhi yeCF8M iR/M. Iyo yakakodzera tembiricha yekushandisa yeMonel M35-1, Monel 400 uye MonelK500 aruminiyamu alloys ndeye -29 ~ 480 ℃.
(2) Cast nickel base alloy Cast nickel alloy (CZ-100) i95%Ni uye 1100%C, uye hapana ndiro yakamonera inofambirana. Iyo CZ-100 ine yakanakisa corrosion kuramba kana ichishandiswa mukuenderera kwepamusoro tembiricha mhinduro ine yakanyanya kudzika kana isina mvura uye alkali. CZ-100 inonyanya kushandiswa mukugadzirwa kweklori-alkali kemikari ine yakakwirira etching concentration (kusanganisira kunyunguduka kwealuminium chloride pasina mvura uye anhydrous) uye munzvimbo dzisina mhangura nesimbi uye zvimwe zvigadzirwa zvesimbi zvinosvibisa zvakatipoteredza. Kanda nickel base alloy CZ-100 valve zvinhu kodhi Ni. CZ-100 aluminium alloy yakakodzera kushanda tembiricha ye -29 ~ 316 ℃.
(3) Hastelloy Hastelloy izita rekutengesa reHastelloy, iro rinonyanya kusanganisira nhevedzano yemisanganiswa, kazhinji Hastelloy B uye Hastelloy C inoshandiswa mumavharuvhu asingadziviriri. Kugadzirwa kweHastelloy B alloys kuenda kuN-12MV (N-12M-1) uye N-7M (zvimwe zvinhu zvinonzi N-12M-2, inozivikanwawo seChlorimet 2 aluminium alloy) muASTM A494 yakakungurutswa kuUNS muASTM B335 N10665. . Hastelloy B inopikisa sulfuric acid yezvikamu zvose, pamwe nekusaderedza munyu uye acids. Iyo corrosion resistant valve yeHastelloy B, kubva pakupokana kwekuora uye kushushikana kwekushomeka kwekudzivirira kutariswa kunofanirwa kusarudzwa yakaderera kabhoni yekuchengetedzwa kwezvakatipoteredza giredhi Hastelloy B (N-7M). Hastelloy zvinhu nhamba Hapana chinodiwa mumunda wevharuvhu. Hastelloy B valve yezvinhu nhamba inogona kutsanangurwa zvakananga nekugadzira nhamba yejoint. Hastelloy B inokodzera kushanda tembiricha ye -29 ℃ ~ 425 ℃.
Iyi chiyero inotsanangura hukuru, dhizaini yechitarisiko, tekinoroji zviyero, nzira dzekuyedza, zviyero zvekuongorora, mamaki ekurongedza uye zvitupa zvemhando yesimbi inopisa-yakatenderedzwa isina tsvina. Iyi chiyero inoshanda kune corrosion isingagadzike inopisa yakakungurutswa simbi yezvese zvinangwa.
