Dewar flasks, inowanzozivikanwa seDewar mabhodhoro kana vacuum flasks,
Post-weld heat treatment ine chinangwa chekubvisa zvakasara zvinonetsa uye kuwedzera kuderera-tembiricha kuoma mumidziyo yekumanikidza.
Unhu hwezvikepe zvakaderera-kupisa zvinotsamira zvakanyanya pazvinhu zvinoshandiswa, kunyanya simbi dzakadzika.
Welding munzvimbo dzakaderera-tembiricha zvinounza akasarudzika matambudziko anoda hunyanzvi hunyanzvi uye hunyanzvi.
Munzvimbo dzinodiwa dzine kutonhora kwakanyanya, kusarudzwa kwezvinhu zvakakodzera zvekudzika-tembiricha kunova kwakakosha pakuchengetedza kutendeseka kwechimiro uye kuita.
Ongorora basa rakakosha rekukurumidza kutonhora tekinoroji mumatangi ekuchengetedza ekudzikira neichi chinyorwa chinonzwisisika.
Iko kushanda kunofanirwa kunyatso kudzora chiyero chemvura uye kudzvanywa kuti isapfuure kukosha kwakatarwa, uye panguva imwe chete, iyo nhanho yemvura inofanirwa kutariswa pakatarisana nesaiti kudzivirira kuwanda.
