Ko te pāmahana whakahaere o te paera ka whakatauhia e te rauemi o te paera.Ko te pāmahana o nga rauemi e whakamahia nuitia ana mo nga paera e whai ake nei:
Te pāmahana whakahaere o te takirere
Wero rino maka hina: -15~250℃
Rere rino whakarewa ngawari: -15~250℃
Waea rino ngongo: -30~350℃
Te teitei o te nickel maka rino valve: te teitei o te pāmahana whakahaere ko te 400 ℃
Waro maitai piha: -29~450℃, tūtohutia pāmahana t<425℃ i roto i te JB/T3595-93 paerewa
1Cr5Mo, koranu rino takirere: ko te pāmahana whakahaere teitei ko 550 ℃
12Cr1MoVA, koranu rino takirere: ko te pāmahana whakahaere teitei ko te 570 ℃
1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti tira kowiri tira: -196~600℃
Waea koranu parahi: -273~250℃
Kirihou takirere (nylon): te pāmahana whakahaere teitei ko 100 ℃
Takiwa Kirihou ( polyether māota): mōrahi pāmahana whakahaere 100 ℃
Kirihou takirere (polyvinyl pūhaumāota): mōrahi pāmahana whakahaere 60 ℃
Rere kirihou (polytrifluorochloroethylene): -60~120 ℃
Takiwa Kirihou (PTFE): -180~150 ℃
Takiwa kirihou (maori rapa diaphragm valve): Morahi te pāmahana whakahaere 60℃
Takiwa kirihou (rapa nitrile, neoprene diaphragm valve): ko te 80 ℃ te pāmahana whakahaere teitei
Kirihou takirere (fluorine rapa diaphragm valve): te pāmahana whakahaere teitei ko 200 ℃
Ina whakamahia te rapa, te kirihou ranei mo te ararewa takirere, ka kaha te aukati i te pāmahana o te rapa me te kirihou
I te nuinga o te waa ka whakamahia nga maru karamik, na te kino o te pāmahana, i roto i nga ahuatanga mahi i raro i te 150°C.I tata nei, kua puta mai he reera karaima tino mahi, ka taea te tu i nga wera teitei i raro i te 1000°C.
He kino te atete ki te pāmahana o nga maru karaihe, a ka whakamahia i roto i nga tikanga mahi i raro i te 90°C.
Ko te parenga o te pāmahana o te tohu tohu he mea iti e nga mea o te mowhiti hiri, a, ko te teitei o te pāmahana whakahaere kaore e neke ake i te 150°C.
Ko nga rauemi tinana o te takirere te nuinga ko: C waro maitai, I 1Cr5Mo chromium molybdenum maitai, H Cr13 raupapa kowiri tira, K malleable maka rino, L konumohe koranu, P 0Cr18Ni9 raupapa kowiri tira, PL 00Cr19Ni10 raupapa he kowiri tira, Q ductile rino, R 0Cr12Ni12Mo raupapa he kowiri tira, RL 00Cr17Ni14Mo2 raupapa He kowiri tira, S kirihou, T parahi me te konukura parahi, Ti titanium me te titanium alloy, V chromium molybdenum vanadium maitai, Z hina te rino maka.
