Ngā Tuke Kore-Pamahana Waro maitai
I hangaia mō te mahi nui i roto i ngā taiao cryogenic me te pāmahana iti, ko ā mātou Tuke Kore-Mahana Waro Rino he mea hanga mai i ngā rauemi kounga teitei pēnei i te API 5L X65, i te maitai motuhake ASTM A333 Grade 6 rānei. E wātea ana i roto i ngā whirihoranga 90° me te 180° me te Radius Roa 1.5D paerewa, kua hangaia ēnei tuke whakarewa hei pupuri i te pakari me te hanganga pai i raro i ngā āhuatanga tino iti iho i te kore, hei ārai i te pakarukaru i roto i ngā tono pēnei i te tukatuka LNG, te rokiroki cryogenic, me ngā pūnaha paipa arctic.
He mea hanga mā te tukanga hanga wera maeneene, ka tukuna e ēnei tuke te haere tonu o te whakarewa me te pumau o te pēhanga ki te whakataurite ki ngā mea kua whakarewahia. Mā te pūtoro piko 1.5D ka pai te rere o te wai me te iti o te aueue me te hekenga pēhanga, ā, mā te whakaritenga tika o te piko whakarewa ka oati kia pai te kounga o ngā whakarewa mara uru katoa. Ko ēnei wāhanga te whiringa pono mō ngā kaihangarau e hoahoa ana i ngā pūnaha paipa haumaru me te pakari e tika ana kia mahi pono mai i te pāmahana taiao ki raro ki te pāmahana makariri.
