I hangaia mai i te maitai waro ASTM A105—kua whaimanahia kia rua ngā tohu mō te kaha ake o te whai i ngā mea e hiahiatia ana—ka whakaratohia e tēnei parirau kaki whakarewa he kaha miihini me te ātete pānga pai rawa atu. Mā te whakatauranga pēhanga 900# ka whakarite kia pono te mahi i roto i ngā pūnaha e mahi ana tae atu ki te 1500 psi i te 100°F (me te whakahekenga pāmahana tika). Ko tōna hoahoa e whakatairanga ana i te whakawhiti maeneene mai i te paipa ki te parirau mā te kaki whakauru, e whakaiti ana i te aueue me te arotau i ngā āhuatanga rere ki runga me raro o te pereti kōhao.
NGĀ PAEREWA WHĀNUI
Whakaaturanga Taipitopito o ngā Hua
Hanganga Ripa:
Ka tīmata ia flange hei poro maitai waro wera, he mea hanga i raro i te pēhanga teitei hei whakapai ake i te hanganga o te witi, hei whakarei ake i ngā āhuatanga miihini (ina koa te pakari me te ātete ki te ngenge), me te whakakore i ngā āputa o roto, i ngā hapa rānei. Mā tēnei tukanga ka whakarite kia ōrite me te kaha ake i ngā momo whakarewa, pereti rānei.
Mīhini Tika:
Mā te mīhini CNC ka oatihia ngā āheinga tika mō ngā mata nui katoa. Ka mīhinihia te poka kia maeneene te mutunga hei whakaiti i te raruraru rere. Ko te mata kua whakaarahia he mea whakakoi tika (125-250 AARH te mutunga) hei whakanui ake i te pupuri o te gasket me te whai huatanga o te hiri. Ka pokaia ngā kōhao pūtu, ā, ka whakakoi-mata kia tika ai te tūnga me te uta pūtu.
Ngā Āhuatanga Motuhake mō te Kōhao:
Kei roto i te flange ngā kōhao waikeri/pūhau e rua 1/2" NPT (he rite rānei) o te Reanga 3 kua whakanohoia kia 90 nekehanga te tawhiti, e tutuki ana i ngā whirihoranga flange kōhao paerewa mō ngā hononga tuku pehanga. Kua hangaia te mata hononga hei pupuri i tētahi pereti kōhao paerewa me tētahi kōhao porowhita, koi te taha hei ine tika i te rere.
Te Whakaritenga Whakarewa:
Kua whakapikohia te pito kaki whakarewa ki te koki paerewa 37.5° me te whenua 1.6mm, kua rite mō te whakarewatanga matua ki te paipa Whakaritenga 160 e ōrite ana. Mā tēnei hoahoa ka tangohia te whakarewatanga mai i te mata o te flange taumaha-teitei, ka whakarato i te hononga tino pai.
Tiwhikete Rauemi:
Kua tukuna mai me te tiwhikete takirua ASTM A105 katoa (ngā āhuatanga matū me te hangarau mai i te tātari wera me te tātari hua), kia mōhio ai ka tutuki, ka hipa rānei te rauemi i ngā whakaritenga mō te kaha whakaputa iti rawa (250 MPa) me te kaha kume (485 MPa).
TE TOHU ME TE TAKAI
Ka whakaritea takitahi ia āputa mō te tuku. Whai muri i te paninga whakamutunga o te hinu ārai-waikura, te VCI rānei (Aukati Waikura Kohu), ka takaihia te āputa ki te kirihou taumaha, ki te pepa ārai-waikura rānei. Ko ngā mata mīhini nui - ina koa ko te mata me te āputa kua ara ake - ka tiakina ki ngā taupoki kirihou, ki te kāri rānei kua tapahia kia rite ki te hiahia. Kātahi ka herea ngā āputa ki te papa rakau, ka tākaihia rānei ki roto i te pouaka rakau kua whakapakaritia, i runga i te rahinga o te ota me te wāhi e haere atu ana.
TE TIROTIRO
Tiwhikete Rauemi: Kei ia flange he Tiwhikete Whakamātautau Mira (MTC) e rite ana ki te EN 10204 3.1 / ASTM A961. Mā tēnei tiwhikete ka taea te whai i te wera taketake o te maitai, ā, kei roto ko:
Tātaritanga matū katoa (C, Mn, P, S, Si, Cu, me ētahi atu)
- Ngā hua o ngā whakamātautau ā-ringa (Kaha Kume, Kaha Tuku, Toronga, Whakaiti i te Horahanga)
- Ngā hua whakamātautau pānga Charpy (mēnā kua tohua mō te ratonga pāmahana iti)
- Ngā tuhinga maimoatanga wera (te whakataurite, mēnā ka whakamahia)
TAKE MAHI NGĀTAHI
I hangaia mō ngā tono ine tika, ka whakamanahia e tēnei flange te pumau o ngā āhuatanga i raro i te huringa wera me te pēhanga. Mā te whakaotinga Raised Face (RF) ka whakarite he hiri pono me ngā gasket hononga porowhita, mowhiti rānei, ā, mā te hanganga pakitara taumaha Schedule 160 ka whakaratohia he tawhā haumaru tāpiri mō ngā ratonga whakahekenga pehanga teitei, whakahekenga pēhanga rānei. Hei tūāpapa mō te ine wai haumaru me te tika, he wāhanga nui tēnei flange kōhao mō ngā miihini e hiahia ana ki te tika, te pakari, me te tutuki katoa ki ngā waehere taputapu pēhanga o te ao.
