Imibuzo Evame Ukubuzwa (Imibuzo Evame Ukubuzwa) – I-Cryogenic Gate Valve (-196°C)
U: Uyini umehluko phakathi kwevalvu yesango eliyi-cryogenic kanye nevalvu yesango ejwayelekile?
A: Amavalvu esango le-cryogenic anezici eziningana ezibalulekile ezingatholakali kumavalvu ajwayelekile: i-bonnet enwetshiwe enepuleti lokuconsa ukuvikela izivalo zesiqu; ukwelashwa okujulile kwe-cryogenic kwazo zonke izingxenye; isango eliqinile le-Stellite kanye nezindawo zokuvala izihlalo ukuze zingagugi; izinto ezikhethekile zokuqina kwezinga lokushisa eliphansi; ukupakisha okuphansi kokukhishwa kwegesi; kanye nokuhlolwa kokusebenza kwe-cryogenic okuphoqelekile ngokwe-BS 6364. Amavalvu esango ajwayelekile ngokuvamile anama-bonnet anganwetshiwe, izindawo zokuvala ezinganwetshiwe, futhi akukho ukuhlolwa kwe-cryogenic.
Q: Lingakanani izinga lokushisa eliphansi lesevisi yama-valve akho esango acwebezelayo?
A: Ama-valve ethu esango ajwayelekile e-cryogenic alinganiselwe isevisi ye--196°C (izinga lokushisa le-nitrogen eliwuketshezi) ngokwe-BS 6364. Ngesevisi ye-hydrogen ewuketshezi (-253°C) noma i-helium ewuketshezi (-269°C), sinikeza imiklamo ekhethekile ngezinto eziguquliwe kanye nezivalo.
U: Kuyini ukwelashwa okujulile kwe-cryogenic futhi kungani kudingeka?
A: Ukwelashwa kwe-cryogenic ejulile yinqubo yokupholisa izingxenye ze-valve zibe yi--196°C okungenani amahora ayi-8. Lokhu kuguqula i-austenite egciniwe, kunciphisa ukucindezeleka okusele, futhi kuqinisekisa ukuzinza kobukhulu ekushiseni kwesevisi. I-BS 6364 idinga ukwelashwa kwe-cryogenic ejulile kuma-valve anezinga lokushisa lesevisi ≤ -101°C.
Q: Kuyini i-Stellite hardfacing futhi kungani isetshenziswa?
A: Ukuqina kwe-Stellite ukusetshenziswa kwe-cobalt-chromium alloy engagugi (Stellite 6 noma 21) ezindaweni zokuvala isango nezihlalo. Lokhu kunikeza ukumelana okuhle kakhulu kokuguguleka, kuvimbela ukugabha nokubamba emazingeni okushisa aphansi, futhi kwandisa impilo yesevisi ye-valve kakhulu. Ukuqina kwe-Stellite kuyisici esijwayelekile sama-valve esango aqinile nge-API 600 ngayinye.
U: Uyini umehluko phakathi kwemiklamo yesango le-wedge kanye neyamasango esilayidi ahambisanayo?
A: Amavalvu esango le-Wedge (i-wedge eqinile noma eguquguqukayo) avame ukusetshenziselwa osayizi abafika ku-24" futhi ahlinzeka ngokusebenza okuhle kakhulu kokuvala. Amavalvu esango le-parallel slide (izihlalo ezintantayo) asetshenziselwa osayizi abakhulu (≥ 12") futhi anciphisa i-torque yokusebenza ngenkathi egcina ukusebenza okuphezulu kokuvala ezisetshenziswayo zokujikeleza kokushisa.
U: Ingabe ukuhlolwa kokusebenza kwe-cryogenic kuyimpoqo?
A: Ngokwe-BS 6364 kanye ne-MSS SP-134, ukuhlolwa kokusebenza kwe-cryogenic kuyimpoqo kuma-valve asetshenziswa ku-LNG kanye nesevisi ye-cryogenic. Ukuhlolwa kumele kwenziwe ku--196°C (i-nitrogen ewuketshezi) ngokuhlolwa kwesihlalo esinomfutho ophansi ngemva kokuqina kokushisa. I-Womic yenza ukuhlolwa kokusebenza kwe-cryogenic okungu-100% kuwo wonke ama-valve esango le-cryogenic ngaphambi kokuthunyelwa.
U: Ingabe ninikeza ukupakisha ukukhishwa komoya okuphansi okusabalele?
A: Yebo. Wonke ama-valve ethu esango acwebezelayo ahlinzekwa nge-low fugitive emission packing evivinywe ngokwe-ISO 15848-1. Singakunikeza isitifiketi se-Class A noma se-Class B kuye ngezidingo zakho.
U: Ungakwazi yini ukunikeza ama-valve esango acwebezelayo ngokuhambisana ne-NACE MR0175?
A: Yebo. Ngezinhlelo zokusebenza ze-cryogenic zesevisi emuncu (i-LNG ene-H2S noma i-ethylene ene-H2S), sihlinzeka ngama-valve esango le-cryogenic anezinto ezihambisana ne-NACE MR0175 / ISO 15156. Lokhu kufaka phakathi ukuhlolwa kobulukhuni, ukukhethwa kwezinto ezifanele, kanye nokuhambisana okubhaliwe.
Q: Singakanani isikhathi esijwayelekile sokuhola sama-valve esango le-cryogenic?
A: Isikhathi esijwayelekile sokulethwa singamaviki ayi-10-14 kumalungiselelo ajwayelekile (osayizi ≤ 24", Isigaba 150-600). Kumasayizi amakhulu (> 24") noma umfutho ophezulu (Isigaba 900+), isikhathi sokulethwa singamaviki ayi-16-22. Ama-oda asheshayo angatholakala ngamanani amancane.
U: Ingabe ninikeza amandla okusebenza kwama-valve esango acwebezelayo?
A: Yebo. Sinikeza ukusebenza ngesandla nge-handwheel noma i-gear operator, i-pneumatic actuation (i-spring-return noma i-double-acting), i-electric actuation (ivuliwe noma iguqulwa), kanye ne-hydraulic actuation. Zonke i-actuator zinosayizi ukuze zinikeze i-torque eyanele emazingeni okushisa aphansi.

Ukusetshenziswa:Ukuhlukaniswa kwethangi lempahla yesithwali se-LNG, ukuvalwa komugqa oyinhloko wempahla, kanye nokuhlukaniswa kwengalo yokulayisha. Izinga lokushisa lesevisi: -162°C (LNG), ingcindezi yomklamo: 1.6-4.0 MPa. Ibhonethi enwetshiwe enepuleti lokuconsa, eqhutshwa yigiya (ngesandla). Umklamo ophephile emlilweni ngokwe-API 6FA, ukupakisha okuphumayo okuphansi ngokwe-ISO 15848-1 Class B. Kuvunyelwe uhlobo lwe-ABS kanye ne-DNV.
Izinselele Zobuchwepheshe Nezixazululo:
1. Amavalvu amakhulu ebhore (30") omugqa omkhulu wemithwalo ye-LNG– Amavalvu esango lesilayidi elingu-30" elihambisanayo ayadingeka ukuze kuhlukaniswe ithangi lempahla elithwala i-LNG. Usayizi omkhulu wawudinga imishini ekhethekile kanye nokuhlanganiswa. Amavalvu esango lesilayidi elihambisanayo ahlinzekwa yi-Womic asebenzisa igiya anezihlalo ezintantayo zokujikeleza okushisa. Wonke amavalvu amane aphumelele ukuhlolwa kwe-cryogenic ku--162°C ngaphandle kokuvuza.
2. Ukuqina kwe-Stellite ukuze kusebenze isikhathi eside– Amavalvu okuthwala i-LNG asebenza njalo (ukuvulwa/ukuvalwa komjikelezo ngamunye wokulayisha/ukukhulula). Isango eliqinile le-Stellite 6 elinikezwe yi-Womic kanye nezindawo zesihlalo zawo wonke amavalvu angu-132. Ubukhulu be-Hardfacing: 2.0mm ngemva komshini wokugaya. Ukuqina: HRC 38-45.
3. Ukuvunyelwa kohlobo lomphakathi wekilasi (i-ABS ne-DNV)– Amavalvu okuthwala i-LNG adinga ukuvunyelwa kohlobo lwe-ABS kanye ne-DNV ngokwekhodi ye-IGC (ikhodi yokuthwala igesi yamazwe ngamazwe). I-Womic ihlanganiswe nabahloli be-ABS kanye ne-DNV ukuze kuhlolwe ukuvunyelwa kohlobo okuhlanganisa ukusebenza kwe-cryogenic, ukuhlolwa kwe-hydrostatic, kanye nokuhlolwa kokukhishwa kwegesi okusabalele. Izitifiketi zokuvunyelwa kohlobo zikhishwe zingakapheli izinsuku ezingama-60.
4. Ukwelashwa okujulile kwe-cryogenic kwe-castings enkulu (umzimba ongu-30")– Ama-castings amakhulu e-CF3M (umzimba ongu-30") asengozini yokuhlaselwa yi-austenite egciniwe. I-Womic yenze ukwelashwa okujulile kwe-cryogenic kwemijikelezo emithathu (ukucwiliswa -196°C, amahora angu-12 ngomjikelezo ngamunye). Ukuhlolwa kabusha kobukhulu kuqinisekisile ukuthi akukho ukuphazamiseka ngemva kokwelashwa.
5. Ukupakisha ukukhishwa komoya okuphansi okusabalele ukuze kuhambisane nemvelo– Izithwali ze-LNG zisebenza ezindaweni ezizwela imvelo ezidinga ukupakisha kwe-ISO 15848-1 Class B. I-Womic ihlinzeka ngokupakisha kwe-graphite ekhipha umoya omncane enomklamo we-bonnet onwetshiwe oqinisekisa ukuthi izinga lokushisa lokupakisha lihlala lingaphezu kuka-20°C.
6. Umhloli we-ABS kanye ne-DNV ubone ukuhlolwa– Wonke ama-valve angu-132 adingekayo, umhloli we-ABS kanye ne-DNV, ubone ukuhlolwa esikhungweni sikaWomic. I-Womic ihlele isimiso sokuhlola nezinhlangano zombili zokuhlukanisa. Ukuhlolwa kuqediwe zingakapheli izinsuku ezingu-30. Akukho ukuhlolwa kabusha okudingekayo.
7. Ukulethwa ngesikhathi esifanele kwesheduli yokwakha yenkampani ye-LNG– Uhlelo lokwakha lwenkampani ye-LNG ludinga ukulethwa kancane kancane ezinyangeni ezingu-8. I-Womic ilethe wonke ama-valve angu-132 ngokuthunyelwa okungu-6, kanti ukuthunyelwa ngakunye kufike ngosuku oludingekayo. Akukho ukubambezeleka ohlelweni lokwakha.
Umphumela:Isithwali se-LNG salethwa ngempumelelo kumnikazi ngo-2023. Wonke ama-valve esango angu-132 e-cryogenic asebenze ku--162°C iminyaka engaphezu kwemibili ngaphandle kwezehlakalo zokulungisa. Umphathi womnikazi uthe: "Ama-valve esango e-cryogenic e-Womic asebenze kahle ngesikhathi sokuhlolwa kwegesi - asizange sithole ukuvuza kuwo wonke ama-valve okuhlukaniswa kwethangi lempahla." Iklayenti likhiphe isivumelwano sohlaka lwezinye izithwali ze-LNG eziyisithupha ezengeziwe.
