Haunga te wai, ko te nuinga o ngā rauemi e whakamahia ana i roto i te whakawhiti wera pereti ko te wairewa kikokore, te wairewa momona, te hauwai konutai, te waikawa whanariki me ētahi atu rauemi matū, e ngāwari ai te waikura o te pereti, te pupuhi me te koroheketanga o te gasket.
Ko te pereti me te gasket ngā huānga matua o te whakawhiti wera pereti, nō reira he mea tino nui te whiriwhiri i te rauemi o te pereti me te gasket.
Kōwhiringa rauemi pereti o te whakawhiti wera pereti:
| Wai parakore, wai awa, hinu kai, hinu kohuke me ētahi atu momo rauemi | kowiri tira (AISI 304, AISI 316, etc.). |
| te wai moana, te tote, te whakatō tote me ētahi atu mea | te titanium me te titanium palladium (Ti, Ti-Pd) |
| Whakarewahia te waikawa whanariki, te wai tote whanariki whakarewahia, te wai kore-waro me ētahi atu rauemi | 20Cr, 18Ni, 6Mo (254SMO) me ētahi atu koranu |
| He pāmahana teitei, he kukū teitei hoki te wairewa houra kautika | Ni |
| Waikawa whanariki kukū, waikawa hauwaiora me te waikawa whākawakawa | Koranu Hastelloy (C276, d205, B20) |
Kōwhiringa rauemi o te gasket mō te whakawhiti wera pereti:
E mōhio ana te nuinga o te tangata he mea noa te whakamahi i ngā hiri rapa, pērā i te EPDM, te rapa nitrile, te rapa nitrile hauwai, te rapa fluororubber me ētahi atu.
| EPDM | Ko te pāmahana ratonga he – 25 ~ 180 ℃. He pai mō te wai wera rawa, te mamaoa, te ozone hau, te hinu whakahinuhinu kāore i te hinu, te waikawa ngoikore, te turanga ngoikore, te ketone, te waipiro, te ester, me ētahi atu. |
| NBR | Ko te pāmahana ratonga he – 15 ~ 130 ℃. He pai mō ngā momo hua hinu kohuke pēnei i te hinu wai, te hinu wahie māmā, te hinu whakahinuhinu, te hinu kararehe me te hinu huawhenua, te wai wera, te wai tote, me ētahi atu. |
| HNBR | Ko te pāmahana ratonga he – 15 ~ 160 ℃. He pai mō te wai pāmahana-tiketike reo-rahi, te hinu mata, te hinu kei roto he whanariki me ngā matū kei roto he whanariki waro, ētahi hinu whakawhiti wera, te hauhautanga hou R134a me te taiao ozone. |
| FKM | Ko te pāmahana ratonga he – 15 ~ 200 ℃. He pai mō ngā momo wai, pērā i te waikawa whanariki kukū, te houra tunutunu, te hinu whakawhiti wera, te hinu wahie waipiro, te hinu wahie waikawa, te mamaoa pāmahana teitei, te wai māota, te phosphate, me ētahi atu. |
