Ukusetyenziswa:Ukwahlulwa kwetanki yemithwalo yenkampani ye-LNG, ukuvalwa komgca wemithwalo ophambili, kunye nokwahlulwa kwengalo yokulayisha. Ubushushu benkonzo: -162°C (LNG), uxinzelelo loyilo: 1.6-4.0 MPa. Ibhonethi eyoluliweyo enepleyiti yokuthontsiza, esetyenziswa yigiya (ngesandla). Uyilo olukhuselekileyo emlilweni ngokwe-API 6FA, ukupakisha okuphumayo okuphantsi ngokwe-ISO 15848-1 Class B. Uhlobo lwe-ABS kunye ne-DNV luvunyiwe.
Imingeni yoBugcisa kunye neZisombululo:
1. Iivalvu ezinkulu zebhore (30") zomgca omkhulu wemithwalo ye-LNG– Iivalvu zesango lesilayidi esihamba kunye ezingama-30" ezifunekayo ukuze kuhlukaniswe itanki yomthwalo wemithwalo ye-LNG. Ubukhulu obukhulu babufuna umatshini okhethekileyo kunye nokuhlanganiswa. Iivalvu zesango lesilayidi esihamba kunye ezisebenza ngegiya ezinezihlalo ezidadayo zokujikeleza ngobushushu. Zonke iivalvu ezine ziphumelele uvavanyo lwe-cryogenic kwi--162°C ngaphandle kokuvuza.
2. I-Stellite hardfacing esebenza ixesha elide– Iivalvu zokuthwala i-LNG zisebenza rhoqo (ukuvulwa/ukuvalwa kumjikelo ngamnye wokulayisha/ukukhulula). Isango eliqinileyo leStellite 6 kunye neendawo zokuhlala ezibonelelwa yiWomic kuzo zonke iivalvu ezili-132. Ubukhulu be-Hardfacing: 2.0mm emva kokwenziwa. Ubunzima: HRC 38-45.
3. Ukuvunywa kohlobo loluntu lweklasi (i-ABS kunye ne-DNV)– Iivalvu zokuthwala i-LNG zifuna imvume yohlobo lwe-ABS kunye ne-DNV ngokweKhowudi ye-IGC (iKhowudi yoMthwali weGesi yaMazwe ngaMazwe). I-Womic idibene nabahloli be-ABS kunye ne-DNV ukuze kuvavanywe imvume yohlobo oluquka ukusebenza kwe-cryogenic, uvavanyo lwe-hydrostatic, kunye novavanyo lokukhupha umoya olubalekayo. Izatifikethi zokuvuma uhlobo zikhutshwe zingadlulanga iintsuku ezingama-60.
4. Unyango olunzulu lwe-cryogenic kwi-castings ezinkulu (umzimba we-30")– Ii-castings ezinkulu ze-CF3M (umzimba we-30") ezisengozini yokuhlaselwa yi-austenite egciniweyo. I-Womic yenze unyango lwe-cryogenic olujikelezayo kathathu (ukuntywila kwi--196°C, iiyure ezili-12 ngomjikelo ngamnye). Ukuhlolwa kwakhona kobukhulu kuqinisekisile ukuba akukho siphazamiso emva konyango.
5. Ukupakisha ukukhutshwa komoya okuncinci okubalekayo ukuze kuthotyelwe imiqathango yokusingqongileyo– Iinkampani ze-LNG zisebenza kwiindawo ezinobuthathaka kokusingqongileyo ezifuna ukupakisha kwe-ISO 15848-1 Class B. I-Womic ibonelela ngokupakisha i-graphite emission ephantsi ephumayo enoyilo olude lwebhonethi ukuqinisekisa ukuba ubushushu bokupakisha buhlala bungaphezulu kwe-20°C.
6. Umhloli we-ABS kunye ne-DNV ubone uvavanyo– Zonke iivalvu ezili-132 ezifunekayo, umhloli we-ABS kunye ne-DNV, ubone uvavanyo kwiziko laseWomic. I-Womic iququzelele ishedyuli yovavanyo kunye nemibutho yokwahlulahlula. Uvavanyo lugqityiwe kwiintsuku ezingama-30. Akukho mfuneko yovavanyo kwakhona.
7. Ukuhanjiswa ngexesha elifanelekileyo kweshedyuli yokwakha yenkampani ye-LNG– Ishedyuli yokwakha yenkampani ye-LNG ifuna ukuhanjiswa ngokwezigaba kwiinyanga ezi-8. I-Womic ihambise zonke iivalvu ezili-132 kwiimpahla ezi-6, kwaye ukuthunyelwa ngakunye kufike ngomhla ofunekayo. Akukho kulibaziseka kwishedyuli yokwakha.
Isiphumo:Isithuthi se-LNG safika ngempumelelo kumniniso ngo-2023. Zonke iivalvu zesango ze-cryogenic ezili-132 zisebenze kwi--162°C kangangeminyaka engaphezu kwemi-2 ngaphandle kweziganeko zokugcinwa. Umphathi womniniso uthe: "Iivalvu zesango ze-cryogenic zaseWomic zisebenze kakuhle ngexesha lovavanyo lwegesi - asizange sifumane kuvuza nanye kuzo zonke iivalvu zokwahlukanisa iitanki zemithwalo." Umthengi ukhuphe isivumelwano sesakhelo seenkampani ze-LNG ezi-6 ezongezelelweyo.
