Ko te pāmahana me te pēhanga mōrahi o te mita rere hikohiko (EMF) e herea ana e te rauemi arai, ngā hiri hikohiko, te akomanga whakamarumaru koiri, me te whakatauranga flange. Kei raro nei he wehewehenga hanganga o ngā rohe paerewa me ngā rohe tino.
1. Ngā Whakatauranga Pāmahana Mōrahi (mā te Rauemi Raina)
Rapa (NR/EPDM/CR)
Tonu: ‐10 °C ki te +80 °C (14 °F ki te 176 °F)
Te tihi poto: +90 °C (194 °F)
Pai rawa atu mō: Wai, wai para, paru, waikawa/kawa ngoikore (pH 4–10)
PTFE (Teflon®)
Tonu: ‐40 °C ki te +130 °C (‐40 °F ki te 266 °F)
Te tihi poto: +150 °C (302 °F)
Kia mōhio: I runga ake i te 130 °C, ka tino heke te ātete ki te korehau
PFA (Perfluoroalkoxy)
Tonu: ‐40 °C ki te +180 °C (‐40 °F ki te 356 °F)
Te tihi poto: +200 °C (392 °F)
Putanga pāmahana teitei: Kua whakatauria mō te 180 °C tonu (me te whakamarumaru koiri akomanga-H)
Uku (Alumina)
Tonu: ‐40 °C ki te +200 °C (‐40 °F ki te 392 °F)
Pai rawa atu mō: Ngā wai wera nui, ngā wai whakakoi, ngā wai tino waikura rānei
Tepe Āraitanga Koiri:
Akomanga E: ≤120 °C (248 °F)
Akomanga H: ≤180 °C (356 °F) (e hiahiatia ana mō ngā tauira pāmahana teitei PFA)
2. Ngā Whakatauranga Pēhanga Mōrahi
Ngā EMF Ahumahi Paerewa (Momo Flange)
Paerewa: PN16 / PN25 (16–25 pae / 230–363 psi)
Pēhanga teitei: PN40 (40 pae / 580 psi) (he mea noa mō ngā raina PFA/PTFE)
Pēhanga tino teitei: PN100 / ASME Cl 600 (100 pae / 1,450 psi) (ngā tauira motuhake, hei tauira, KROHNE OPTIFLUX 4300)
Tino Kaha: Tae atu ki te 1,500 pae (21,750 psi) (ngā pūoko pēhanga teitei ritenga mō te hinu/hau)
Ngā Herenga Pēhanga e Hangai ana ki te Raina
Rapa: Teitei PN25 (25 pae) (mōrearea o te wehewehe i te pēhanga teitei ake)
PTFE: Teitei PN40 (40 pae); ehara mō te korehau (ka hinga i raro i te pēhanga kino)
PFA: Teitei PN40 (40 pae); ātete tino pai ki te korehau (‐1 pae / 29.9 inHg)
