    Whakaritenga Whakamatau

    Whakamatau Hydraulic
    Ka mahia nga whakamatautau wai mo nga paipa rino takitahi. Ko 20 MPa te pēhanga whakamātautau mōrahi. I raro i te pehanga whakamatautau, ko te wa whakapumautanga kaua e iti iho i te 10 s, kaore hoki e whakaaetia te pakaru o te putorino maitai.
    Whakamātautau papatahi
    Me whakahaere te whakamatautau papatahi mo te paipa maitai me te diameter o waho nui ake i te 22 mm
    Te whakamatautau mura
    Ko te maitai o te hanga waro kounga teitei me nga paipa rino kowiri (whana-wera) me te diameter o waho kaua e neke ake i te 76 mm me te matotoru o te pakitara kaua e neke atu i te 8 mm ka tukuna ki te whakamatautau whakawhanui. Me whakahaere te whakamatautau mura i te pāmahana rūma. Ko te 60% o te mura o te whanui o waho o te tauira i muri i te taper matua o runga ka tutuki nga whakaritenga o te ripanga 7. Kaore he kapiti, he kapiti ranei e whakaaetia i runga i te tauira i muri i te mura. E ai ki nga whakaritenga a te kaitono me te tohu i roto i te kirimana, ka taea hoki te whakamahi i te rino hanganga koranu mo te whakawhanui whakamatautau.
    Te whakamatautau kore kino
    Ko nga putorino rino ka pa ki te kitenga koha ultrasonic tetahi i tetahi i runga i nga tikanga o GB / T 5777-2008. E ai ki nga whakaritenga a te kaitono, ka taea te taapiri i etahi atu whakamatautau kore-kino i muri i nga whiriwhiringa i waenga i te kaiwhakarato me te kaitono me te tohu i roto i te kirimana.
    Te whakamatautau waikura i waenga
    Me whakahaere te whakamatautau waikura waenga mo te paipa rino kowiri (te wera-wera). Ko te tikanga whakamatautau kia rite ki nga whakaritenga o te tikanga Hainamana E i roto i te GB / T 4334-2008, a kaore e whakaaetia te ahua o te waikura intergranular i muri i te whakamatautau.
    I muri i nga whiriwhiringa i waenga i te kaiwhakarato me te kaitono, ka tuhia i roto i te kirimana, ka taea e te kaitono te tohu etahi atu tikanga whakamatautau waikura.
