Zida zamankhwala ndi mapaipi amadalira kwambiri zitsulo zosapanga dzimbiri, kuti apereke zomangamanga zosagwira ntchito, zosagwira dzimbiri zomwe zimafunikira popanga ndi kutentha.kutsekereza.Komabe, ma thermoplastics alipo omwe angapereke zabwino kapena zotsika mtengo.Mapulasitiki otsika mtengo monga polypropylene (PP) ndi polyvinyl chloride (PVC) angakhale ovomerezeka ku machitidwe osakakamiza.Zina, monga polyvinylidene fluoride (PVDF) zomwe zimapereka kukana kutentha kwambiri, zitha kukhala zoyenera pamadzi olipidwa, ngakhale zimafunikira kuthandizira mosalekeza pamagwiritsidwe ntchito otentha.Mtengo wa dongosolo la PVDF ukhoza kukhala pafupifupi 10-15 peresenti kuposa mtengo wazitsulo zosapanga dzimbiri kamodzi zinthu monga passivation, boroscope radiographic inspection, etc., zikuphatikizidwa.Njira zatsopano zolumikizira machubu a PVDF zimasiya chowotcherera chosalala kwambiri kuposa kotheka ndi chitsulo chosapanga dzimbiri.Kutentha kokwera, komabe, kukulitsa kutentha kwa pulasitiki kumakhala vuto lalikulu.
Kusankhidwa kwa zinthu kuyenera kukhala kosasinthasintha (zonse 316L kapena zonse 304L etc.) panthawi yonse yogawa, kusungirako, ndi kukonza machitidwe ngati kupititsa patsogolo nthawi zonse kukukonzekera.
Pamadzi olimbikira, kugwiritsa ntchito chitsulo cha 316L ndikwabwino.Insulation kwamapaipi opanda bangaziyenera kukhala zopanda ma chloride, ndi zopachika zopatsirana zodzipatula kuti zisawononge dzimbiri.
304L ndi 316L zitsulo zosapanga dzimbiri zakhala zokonda zamakampani m'matanki posungira madzi ofunikira.Zinthu za jekete zomwe zakhudzana ndi chipolopolo ziyenera kugwirizana, kupewa kuchepa kwa chromium m'madera omwe akhudzidwa ndi weld.Kusungirako madzi kosafunikira sikungafune kukana kwa dzimbiri kapena kugwiritsa ntchito ma aloyi otsika a carbon nickel-chromium ndi kumaliza kwapadera, kutengera mwiniwake.'s mfundo za madzi.
