Pūtu-rua-pito kounga teitei
Ngā rauemi matua me ngā āhuatanga
Rauemi:45# maitai (tohu 8.8), 40Cr maitai koranu (tohu 10.9).
Ngā Āhuatanga:
Te kaha kume teitei: Ko te kaha kume o ngā pūtu 10.9 he ≥1040MPa, he pai mō ngā kawenga taumaha;
Kāore he mōrearea o te pakarukaru hauwai: ka karohia e te maimoatanga pango te pakarukaru hauwai hiko, he pai mō ngā taputapu tino tika;
Te Whakaritenga: Ka taea te whakarite i te roa o te tokotoko rama waenga kia tutuki ai ngā whakaritenga tāutanga rerekē.
Ngā mahi me ngā horopaki e tika ana
Ngā Mahi:
Honoa ngā ipu matotoru-taiepa, ngā flanges me ētahi atu wāhanga kāore e taea te whakamahi i ngā pūtu kotahi-upoko;
Whakakapia te whakarewa kia māmā ai te wetewete me te tiaki.
Horopaki:
Ngā taputapu matū (te flange o te tauhohenga), ngā mīhini keri (te nohoanga o te kuru), ngā taputapu hiko (te pūkaha whakawhiti).
Te tāutanga me te tiaki
Tāutanga:
Ka whakawirihia tetahi pito ki roto i te kōhao miro o te pito pumau, ā, ka whakakīia tetahi pito ki te nati;
Whakamahia ngā mīhini horoi papatahi me ngā mīhini horoi puna hei whakarei ake i te mahi ā-aukati-wetewete.
Te Tiaki:
Tirohia te piripono o ngā nati i ia wā, ā, whakapiritia anō i roto i te taiao pāmahana teitei (>200℃);
Āta karohia te ruku roa o ngā pūtu mangu hei ārai i te kino o te kiriata waikura.
