Ngaphezu kwamanzi, Iningi lemithombo yezindaba esetshenziselwa i-plate heat exchanger iyisisombululo esithambile, isixazululo esicebile, i-sodium hydroxide, i-sulfuric acid kanye neminye imithombo yamakhemikhali, okulula ukubangela ukugqwala kwepuleti nokuvuvukala nokuguga kwe-gasket.
Ipuleti kanye ne-gasket yizici ezibalulekile zesishintshi sokushisa samapuleti, Ngakho ukukhethwa kwepuleti ne-gasket impahla kubaluleke kakhulu.
Ukukhetha impahla yepuleti yesishintshi sokushisa kwepuleti:
| Amanzi ahlanzekile, amanzi omfula, amafutha adliwayo, amafutha amaminerali kanye neminye imidiya | insimbi engagqwali (AISI 304, AISI 316, njll.). |
| amanzi olwandle, amanzi anosawoti, usawoti kanye nezinye imidiya | i-titanium ne-titanium palladium(Ti, Ti-Pd) |
| Nciphisa i-sulfuric acid, i-sulfur salt aqueous solution, i-inorganic aqueous solution kanye neminye imidiya | I-20Cr, 18Ni, 6Mo (254SMO) namanye ama-alloys |
| Izinga lokushisa eliphezulu kanye nokuhlushwa okuphezulu kwe-caustic soda medium | Ni |
| I-sulfuric acid egxilile, i-hydrochloric acid ne-phosphoric acid medium | Ingxubevange ye-Hastelloy (C276, d205, B20) |
Ukukhetha okubalulekile kwe-gasket yesishintshi sokushisa kwepuleti:
Iningi labantu liyazi ukuthi i-rubber sealing gaskets yizinto ezisetshenziswa kakhulu, njenge-EPDM, i-nitrile rubber, i-hydrogenated nitrile rubber, i-fluororubber njalonjalo.
| I-EPDM | Izinga lokushisa lesevisi ngu-25 ~ 180 ℃.Ilungele amanzi ashisayo aphakathi nendawo, umusi, i-ozone yasemkhathini, uwoyela wokugcoba ongasuselwe ku-petroleum, i-asidi ebuthakathaka, isisekelo esibuthakathaka, i-ketone, utshwala, i-ester, njll. |
| I-NBR | Izinga lokushisa lesevisi ngu-15 ~ 130 ℃.Ifanele imikhiqizo ehlukahlukene kawoyela wamaminerali efana ne-fluid medium, uwoyela we-fuel light, amafutha okugcoba, amafutha ezilwane nemifino, amanzi ashisayo, amanzi anosawoti, njll. |
| I-HNBR | Izinga lokushisa lesevisi ngu-15 ~ 160 ℃.Ilungele amanzi anoketshezi oluphakathi naphakathi nendawo, uwoyela ongahluziwe, uwoyela oqukethe isibabule nezinhlanganisela eziqukethe isibabule, amanye amafutha okudlulisa ukushisa, isiqandisi esisha esingu-R134a kanye nemvelo ye-ozone. |
| I-FKM | Izinga lokushisa lesevisi ngu-15 ~ 200 ℃.Ilungele i-fluid medium, njenge-concentrated sulfuric acid, i-caustic soda, uwoyela wokudlulisa ukushisa, uwoyela wamafutha otshwala, uwoyela we-asidi kaphethiloli, umusi oshisa kakhulu, amanzi e-chlorine, i-phosphate, njll. |
