Nā Nīnau i Nīnau Pinepine ʻia (FAQ) - Cryogenic Gate Valve (-196°C)
Q: He aha ka ʻokoʻa ma waena o kahi kiwikā puka cryogenic a me kahi kiwikā puka maʻamau?
A: Loaʻa i nā kiwikā puka cryogenic kekahi mau hiʻohiʻona koʻikoʻi i loaʻa ʻole i nā kiwikā maʻamau: ka pāpale i hoʻolōʻihi ʻia me ka pā drip e pale i nā sila kumu; ka mālama hohonu ʻana i ka cryogenic o nā ʻāpana āpau; nā ʻili sila puka paʻa Stellite a me nā noho no ke kūpaʻa ʻana i ka ʻaʻahu; nā mea kūikawā no ka paʻakikī haʻahaʻa haʻahaʻa; ka hoʻopili ʻana i ka hoʻokuʻu mahuka haʻahaʻa; a me ka hoʻāʻo hana cryogenic mandatory e like me BS 6364. ʻO ka maʻamau, loaʻa i nā kiwikā puka maʻamau nā pāpale i hoʻolōʻihi ʻole ʻia, nā ʻili sila paʻa ʻole, a ʻaʻohe hoʻāʻo cryogenic.
Q: He aha ka mahana lawelawe haʻahaʻa loa no kāu mau kiwikā puka cryogenic?
A: Ua helu ʻia kā mākou mau kiwikā puka cryogenic maʻamau no ka lawelawe -196°C (mahana naikokene wai) e like me BS 6364. No ka lawelawe hydrogen wai (-253°C) a i ʻole ka lawelawe helium wai (-269°C), hāʻawi mākou i nā hoʻolālā kūikawā me nā mea i hoʻololi ʻia a me nā sila.
Q: He aha ka lapaʻau cryogenic hohonu a no ke aha e pono ai?
A: ʻO ka mālama ʻana i ka cryogenic hohonu ke kaʻina hana o ka hoʻomaʻalili ʻana i nā ʻāpana valve i -196°C no ka liʻiliʻi he 8 mau hola. Hoʻololi kēia i ka austenite i mālama ʻia, hoʻomaha i nā koʻikoʻi koena, a hōʻoia i ke kūpaʻa dimensional ma ka mahana lawelawe. Pono ʻo BS 6364 i ka mālama ʻana i ka cryogenic hohonu no nā valves me nā mahana lawelawe ≤ -101°C.
Q: He aha ka Stellite hardfacing a no ke aha i hoʻohana ʻia ai?
A: ʻO ka Stellite hardfacing ka hoʻopili ʻana o kahi cobalt-chromium alloy kūpaʻa i ke kapa (Stellite 6 a i ʻole 21) i nā ʻili sila o ka puka a me ka noho. Hāʻawi kēia i ke kūpaʻa maikaʻi loa i ke kapa, pale i ka galling a me ka hopu ʻana i nā mahana cryogenic, a hoʻolōʻihi i ke ola lawelawe valve. ʻO ka Stellite hardfacing kahi hiʻohiʻona maʻamau o nā valves puka cryogenic e like me API 600.
Q: He aha ka ʻokoʻa ma waena o nā hoʻolālā puka wedge a me nā hoʻolālā puka paheʻe like?
A: Hoʻohana pinepine ʻia nā kiwikā puka wedge (wedge paʻa a palupalu paha) no nā nui a hiki i ka 24" a hāʻawi i ka hana pani maikaʻi loa. Hoʻohana ʻia nā kiwikā puka paheʻe like (nā noho lana) no nā nui nui (≥ 12") a hoʻemi i ka torque hana me ka mālama ʻana i ka hana sila maikaʻi loa i nā noi paikikala thermal.
Q: He mea koi ʻia ka hoʻāʻo hana cryogenic?
A: E like me BS 6364 a me MSS SP-134, he mea koi ʻia ka hoʻāʻo ʻana i ka hana cryogenic no nā valves i hoʻohana ʻia ma ka LNG a me ka lawelawe cryogenic. Pono e hana ʻia nā hoʻāʻo ma -196°C (naikokene wai) me ka hoʻāʻo noho pneumatic haʻahaʻa ma hope o ka hoʻopaʻa ʻana o ka mahana. Hana ʻo Womic i ka hoʻāʻo hana cryogenic 100% ma kēlā me kēia valve puka cryogenic ma mua o ka hoʻouna ʻana.
Q: Ke hāʻawi nei ʻoe i ka hoʻopili hoʻokuʻu haʻahaʻa haʻahaʻa?
A: ʻAe. Hoʻolako ʻia kā mākou mau kiwikā puka cryogenic a pau me ka hoʻopili hoʻokuʻu haʻahaʻa haʻahaʻa i hoʻāʻo ʻia i ka ISO 15848-1. Hiki iā mākou ke hāʻawi i ka palapala hōʻoia Class A a i ʻole Class B ma muli o kāu mau koi.
Q: Hiki iā ʻoe ke hoʻolako i nā kiwikā puka cryogenic me ka hoʻokō ʻana o NACE MR0175?
A: ʻAe. No nā noi cryogenic lawelawe ʻawaʻawa (LNG me H2S a i ʻole ethylene me H2S), hāʻawi mākou i nā valves puka cryogenic me nā mea kūpono NACE MR0175 / ISO 15156. Hoʻokomo pū kēia i ka hoʻāʻo paʻakikī, ke koho ʻana i nā mea kūpono, a me ka hoʻokō palapala.
Q: He aha ka manawa alakaʻi maʻamau no nā kiwikā puka cryogenic?
A: ʻO ka manawa alakaʻi maʻamau he 10-14 mau pule no nā hoʻonohonoho maʻamau (nā nui ≤ 24", Papa 150-600). No nā nui nui (> 24") a i ʻole ke kaomi kiʻekiʻe (Papa 900+), ʻo ka manawa alakaʻi he 16-22 mau pule. Loaʻa paha nā kauoha wikiwiki no nā nui liʻiliʻi.
Q: Ke hāʻawi nei ʻoe i ka hoʻāla ʻana no nā kiwikā puka cryogenic?
A: ʻAe. Hāʻawi mākou i ka hana lima me ka mea hoʻohana huila lima a i ʻole ka mea hoʻokele kia, ka hoʻāla pneumatic (spring-return a i ʻole double-acting), ka hoʻāla uila (on-off a modulating paha), a me ka hoʻāla hydraulic. Hoʻonohonoho ʻia nā actuator āpau e hāʻawi i ka torque kūpono i nā mahana cryogenic.
