Mibvunzo Inowanzo bvunzwa (Mibvunzo Inowanzo bvunzwa) - Vharuvhu yeGedhi reCryogenic (-196°C)
Mubvunzo: Ndeupi musiyano uripo pakati pevharuvhu yegedhi ine cryogenic nevharuvhu yegedhi yakajairwa?
A: Mavharuvhu egedhi ane zvinhu zvakakosha zvisingawanikwe mumavharuvhu akajairwa: bhoneti yakatambanudzwa ine drip plate yekudzivirira stem seals; kurapwa kwakadzika kwe cryogenic kwezvinhu zvese; nzvimbo dzekuvhara gedhi dzakasimba dzeStellite nedzekuchengetedza chigaro kuti dzisaparare; zvinhu zvakakosha zvekusimba kwekupisa kwakaderera; kurongedza kwakaderera kwekubuda kwemhepo; uye kuyedzwa kwekushanda kwe cryogenic kunofanirwa kuteverwa neBS 6364. Mavharuvhu egedhi akajairwa anowanzova nemabhoneti asina kutambanudza, nzvimbo dzekuvhara simbi dzisina kusimba, uye hapana kuyedzwa kwe cryogenic.
Mubvunzo: Ndeipi tembiricha shoma inoshandiswa pamavharuvhu egedhi rako re cryogenic?
A: Mavharuvhu edu egedhi e cryogenic akajairwa akapihwa sevhisi ye -196°C (tembiricha yenitrogen yemvura) zvichienderana neBS 6364. Kune sevhisi yehydrogen yemvura (-253°C) kana ye helium yemvura (-269°C), tinopa magadzirirwo akasarudzika ane zvinhu zvakagadziriswa uye zvisimbiso.
Mubvunzo: Chii chinonzi kurapwa kwe deep cryogenic uye nei kuchidikanwa?
A: Kurapa ne cryogenic yakadzika inzira yekutonhodza zvikamu zvevharuvhu kusvika -196°C kwemaawa masere. Izvi zvinoshandura austenite yakachengetwa, zvinoderedza kushushikana kwakasara, uye zvinovimbisa kugadzikana kwehukuru pakupisa kwekushanda. BS 6364 inoda kurapwa ne cryogenic yakadzika yemavharuvhu ane tembiricha yekushanda ≤ -101°C.
Mubvunzo: Chii chinonzi Stellite hardfacing uye nei ichishandiswa?
A: Stellite hardfacing ibasa rekushandisa cobalt-chromium alloy (Stellite 6 kana 21) rinodzivirira kupera simba panzvimbo dzinovhara magedhi nechigaro. Izvi zvinopa simba rakanaka rekudzivirira kupera simba, zvinodzivirira kupwanyika kana kubatwa nekupisa kusingadzoreki, uye zvinowedzera hupenyu hwevharuvhu zvakanyanya. Stellite hardfacing ibasa remavharuvhu emagedhi anodzivirira kupera simba paAPI 600.
Mubvunzo: Ndeupi musiyano uripo pakati pemagadzirirwo egedhi re wedge ne parallel slide gate?
A: Mavharuvhu egedhi reWedge (wedge yakasimba kana inochinjika) anowanzo shandiswa pahukuru hunosvika 24" uye anopa mashandiro akanaka ekudzima. Mavharuvhu egedhi reparallel slide (zvigaro zvinoyangarara) anoshandiswa pahukuru hukuru (≥ 12") uye anoderedza torque yekushanda uku achichengetedza mashandiro epamusoro ekuvhara mukushandiswa kwemhepo inopisa.
Mubvunzo: Kuongororwa kwekushanda kwe cryogenic kunosungirwa here?
A: Maererano neBS 6364 neMSS SP-134, kuyedzwa kwe cryogenic performance kunosungirwa kumavharuvhu anoshandiswa muLNG uye cryogenic service. Kuyedzwa kunofanirwa kuitwa pa -196°C (liquid nitrogen) nekuyedzwa kwechigaro chine simba shoma mushure mekudzikamiswa kwekupisa. Womic inoita kuyedzwa kwe cryogenic performance kwe100% pavharuvhu yega yega ye cryogenic gate isati yatumirwa.
Mubvunzo: Munopa here kurongedza zvinhu zvinoburitsa utsi hushoma?
A: Ehe. Mavharuvhu edu ese egedhi ane cryogenic ane low fugitive emission packing yakaedzwa zvinoenderana neISO 15848-1. Tinogona kupa certification yeClass A kana Class B zvichienderana nezvamunoda.
Mubvunzo: Munogona here kupa mavharuvhu egedhi ane cryogenic zvinoenderana neNACE MR0175?
A: Ehe. Kune mashandisirwo e cryogenic (LNG ine H2S kana ethylene ine H2S), tinopa mavharuvhu egedhi ane cryogenic ane zvinhu zvinoenderana neNACE MR0175 / ISO 15156. Izvi zvinosanganisira kuyedzwa kwekuoma, kusarudzwa kwezvinhu zvakakodzera, uye kutevedzera zvakanyorwa.
Q: Ndeipi nguva yakajairika yekutungamira kwemavharuvhu egedhi ane cryogenic?
A: Nguva yakatarwa yekutumira zvinhu imavhiki gumi kusvika gumi nemana ekugadzirisa zvinhu zvakajairwa (saizi ≤ 24", Kirasi 150-600). Kune saizi dzakakura (> 24") kana kumanikidzwa kwakanyanya (Kirasi 900+), nguva yakatarwa imavhiki gumi nematanhatu kusvika makumi maviri nemaviri. Maodha ekukurumidzira anogona kuwanikwa kune mashoma.
Mubvunzo: Munopa here nzira dzekushandisa mavharuvhu egedhi ane cryogenic?
A: Ehe. Tinopa mashandiro nemaoko neruoko kana giya rinoshandisa, pneumatic actuation (spring-return kana double-acting), electric actuation (on-off kana modulating), uye hydraulic actuation. Ma actuator ese ane saizi yekupa torque yakakwana pakupisa kwe cryogenic.

Mashandisirwo:Kuchengetedzwa kwetangi rekutakura zvinhu reLNG, kuvharwa kwetambo huru yekutakura zvinhu, uye kuchengetedzwa kweruoko rwekutakura zvinhu. Kupisa kwebasa: -162°C (LNG), kumanikidzwa kwedhizaini: 1.6-4.0 MPa. Bhoneti yakawedzerwa ine drip plate, inoshandiswa negiya (nemaoko). Dhizaini isingatsvedzi moto paAPI 6FA, kurongedza kwakaderera kwemhepo inobuda paISO 15848-1 Class B. ABS neDNV type zvinotenderwa.
Matambudziko ehunyanzvi nemhinduro:
1. Mavharuvhu makuru (30") emuchina mukuru wekutakura zvinhu weLNG– Mavharuvhu egedhi remasiraidhi ane 30" anodiwa kuti tangi rekutakura zvinhu reLNG rive rakasanganiswa. Saizi hombe yacho yaida michina yakagadzirwa uye kugadzirwa kwakagadzirwa. Mavharuvhu egedhi remasiraidhi aishandiswa neWomic aishandiswa negiya ane zvigaro zvinoyangarara zvekupisa. Mavharuvhu ese mana akapa bvunzo ye cryogenic pa -162°C pasina kubuda kwemvura.
2. Stellite hardfacing inoshanda kwenguva refu– Mavharuvhu anotakura LNG anowanzo shandiswa (kuvhurwa/kuvharwa kwega kwega kwekurodha/kuburitsa). Gedhi reStellite 6 rakagadzirwa neWomic rine mavharuvhu 132 ese. Ukobvu hwemavharuvhu akaomarara: 2.0mm mushure mekugadzira. Kuomarara: HRC 38-45.
3. Kubvumidzwa kwerudzi rwevanhu vekirasi (ABS neDNV)– Mavharuvhu ekutakura LNG anoda kubvumidzwa kwemhando yeABS neDNV zvichienderana neIGC Code (International Gas Carrier Code). Womic yakabatana nevaongorori veABS neDNV kuti vaongorore kubvumidzwa kwemhando kusanganisira cryogenic performance, hydrostatic, uye fugitive emission tests. Zvitupa zvekubvumidzwa kwemhando zvinopihwa mukati memazuva makumi matanhatu.
4. Kurapa kwakadzama kwe cryogenic kwe castings hombe (30" muviri)– Matombo makuru eCF3M (muviri we30") anogona kubatwa neaustenite yakachengetwa. Womic yakarapa cryogenic yezvikamu zvitatu (-196°C inonyoroveswa, maawa gumi nemaviri padenderedzwa). Kuongororazve kwakaratidza kuti hapana kukanganiswa mushure mekurapwa.
5. Kurongedza kwakaderera kwekubuda kwemhepo inobuda nekuda kwekutevedzera nharaunda– Zvifambiso zveLNG zvinoshanda munzvimbo dzinonyanya kukanganiswa nezvakatipoteredza zvinoda ISO 15848-1 Class B packing. Womic inopa graphite packing yakaderera ine dhizaini yakareba inoita kuti kurongedza kugare pamusoro pe -20°C.
6. Muongorori weABS neDNV akaona kuyedzwa– Mavharuvhu ese 132 aidiwa neABS neDNV surveyor akaona kuyedzwa paWomic's facility. Womic yakaronga purogiramu yekuyedza nemasangano ese ari maviri ekupatsanura. Kuyedzwa kwapera mukati memazuva makumi matatu. Hapana bvunzo zvakare inodiwa.
7. Kutumirwa panguva chaiyo kwehurongwa hwekuvaka kweLNG carrier- Purogiramu yekuvaka yekutakura LNG yaida kutumirwa zvishoma nezvishoma kwemwedzi misere. Womic yakaendesa mavharuvhu ese 132 muzvikamu zvitanhatu, uye kutumira kwega kwega kwakasvika pazuva chairo raidiwa. Hapana kunonoka purogiramu yekuvaka.
Mhedzisiro:Chifambiso cheLNG chakaendeswa kumuridzi muna 2023. Mavharuvhu ese 132 egedhi re cryogenic ave achishanda pa -162°C kwemakore anopfuura maviri pasina zviitiko zvekugadzirisa. Mukuru wemuridzi akati: "Mavharuvhu egedhi re cryogenic reWomic akashanda zvakanaka panguva yekuyedzwa kwegasi - hatina kuwana chero kubuda kwemvura pamavharuvhu ese ekutakura matangi emotokari." Mutengi akapa chibvumirano chekuwedzera mamwe mavharuvhu matanhatu e LNG.
