Cryogenic mavharuvhu anoshandiswa zvakanyanya muminda yefetereza, LNG uye petrochemical indasitiri. Kunze kweiyo nitrogen yemvura uye mamwe magasi anert inert, mazhinji enhau anodzorwa haangobatiki uye anoputika, asiwo gasification inoitika kana ichipisa kana kupenya. , Zvinokonzera kukurumidza kuwedzera kwevhoriyamu, zviri nyore kukonzera kuvuza uye kuputika. Muindasitiri, mavharuvhu anoshandiswa mukupisa kwepakati pazasi -40 ℃ anowanzo kunzi cryogenic mavharuvhu, uye mavharuvhu anoshandiswa mukati tembiricha pazasi -101 ℃ anonzi ekupedzisira-yakaderera tembiricha mavharuvhu.
Kusarudzwa kwezvinhu zve cryogenic valves:
Iyo mechanical properties yesimbi pane yakaderera tembiricha yakasiyana neaya ari mukamuri tembiricha. Kuwedzera kune simba, kuderera-tembiricha kukanganisa kuoma ndiyo inonyanya kukosha index kune yakaderera-tembiricha simbi. Iyo yakaderera tembiricha inokanganisa kuoma kwechinhu kune hukama neiyo brittle shanduko tembiricha yechinhu. Iyo yakadzikira iyo brittle shanduko tembiricha yechinhu, zviri nani iyo yakaderera tembiricha kukanganisa kuoma kwezvinhu. Zvishandiso zvesimbi zvine body-centered cubic lattice senge kabhoni simbi zvine yakaderera-tembiricha inotonhora brittleness, nepo zvesimbi zvine kumeso-centered cubic lattice senge austenitic stainless simbi hazvina zvazvinokanganisa pakusimba kwekupisa kwakadzikira.
Yakadzika tembiricha vharafu muviri, bhoneti uye zvimwe zvinomanikidza-inodzivirira zvikamu zvinowanzo gadzirwa nemidziyo ine yakanaka yakaderera tembiricha simba uye kuoma. Panguva imwecheteyo, zvinhu zvakaita seweldability, machinability, kugadzikana uye hupfumi zvinofanirwa kutariswa.
Paunenge uchigadzira, matatu akadzika-tembiricha mazinga e -46 ℃, -101 ℃ uye -196 ℃ anowanzoshandiswa. Yakaderera-tembiricha kabhoni simbi inowanzo shandiswa kune -46 ℃ yakaderera-kupisa giredhi, uye mazana matatu akatevedzana austenitic simbi isina tsvina inowanzoshandiswa ku -101 ℃ uye -196 ℃ giredhi yakaderera-tembiricha. Iyi simbi isina tsvina ine simba rine mwero, kusimba kwakanaka uye kuita kwakanaka kwekugadzirisa.
