Paerewa PC mo te Taapapa LNG
He pai tenei hua mo nga hanganga raima whakahirahira o nga kaupapa waapu penapena LNG me te whakamahi i etahi atu waahi iti te pāmahana. Ko tona hanganga he 1X7 me te diameter ingoa ko 15.20mm, 15.7mm & 17.80mm. Ko te rereketanga e whakaaetia ana mo te diameter ka whakatutukihia kia rite ki te + 0.20mm, -0.10mm. Ko te tohu kaha ko 1860Mpa; ko te roanga o te roanga i raro i te kaha nui (Agt) me ≥5.0%; ko te whati i muri o te wehenga he kirihou; ko te utu whakaheke waahanga (Z) ko ≥25%; te diameter o te waea waea waenganui kaore i te iti iho i te 1.03 nga wa o te diameter waea o waho. Kaore he tohu maitai a te whenu. He pai te mahi-punga-punga-punga pai. I te -196 +/- 5 ° C, kua taurite te whenu me te huihuinga punga, ko te taunga whakakapinga whaihua (ή) ko te ≥95%, ko te tapeke o te roanga kei raro i te taumahatanga nui -2.0%. Koinei te kowhiringa tuatahi mo te miihini whakaoho-patu o te raima tank o waho o te LNG. Ka taea e te hua te whakatutuki i nga whakaritenga o prEN10138, EN14620-3 me etahi atu paerewa.
