Ngā whakaritenga mō te maimoatanga wera: te whakarite i te 850°C; te tinei i te 880°C; te whakamahana i te 600°C.
Rauemi: he mea hanga ki te kounga teiteimaitai hanganga waromā te hurihuri wera, mā te kume matao rānei.
Whakamahinga: whakamahia mō te hanga paipa pakitara matao-wai, paipa wai kohua, paipa mamaoa tāke wai o te waka tereina me te paipa pereki āwhata, me ētahi atu.
Ngā whakatakotoranga me te kounga āhua:
Ia puranga ongā paipa maitaiMe tirotirohia takitahi, ā, me kore he ngatata, he takai, he hapa kiri takirua i te mata; Me mahi te kimi hapa ultrasonic mō ia paipa maitai hei tirotiro i ngā āhuatanga miihini o te whakarewa. Ko te whānui o te whakakaha roa o te whakarewa he 0.2-0.25mm, ko te whānui o te whakakaha roa o te whakarewa porowhita he 0.75-1mm, ā, kaua e iti iho i te 0.25mm te whakakaha ahotea roa i te putanga.
Te hanganga matū E tutuki ana te hanganga matū o te hua kua oti ki ngā whakaritenga o GB 222-84.
Ngā āhuatanga ā-tinana me ngā āhuatanga ā-mīhini:
1) Me papatahi te pihi ahotea-taumahatanga o te whakamātautau kume, me te kore he huringa ohorere
2) Whakamātautau pānga Ka whakamatautauria te pakari pānga pāmahana-iti o te tauira mā te tikanga whakamātautau piko makariri i te pāmahana kua tohua.
3) Kāore e whakaaetia kia pakaru ngā paipa e mura ana i ngā taputapu waipēhi, hau rānei.
4) Kaua te kore-taurite o te ahotea o te whakamātautau piko e neke ake i te uara kua tohua.
Te rere o te tukanga: Whai muri i te miro aunoa o te rīpene maitai kia rite ki te kōpae angiangi, ā, ka hangaia tonutia, ka whakatauritea e te mīhini whakatika maha-haere, kātahi ka uru ki te waeine whakarewa auau-teitei. Ka werohia ngā pito e rua e te mīhini whakarewa auau-teitei kia hanga he whakarewa porowhita kōpikopiko. Whai muri i te whakarewa, ka rahihia te paipa maitai, ka tapahia e te waeine whakarahi me te tapahi. Hei whakamutunga, ka tineia te paipa maitai, ka whakamahanahia e te waeine whakaoti, kātahi ka rehuhia ki te paninga tuatahi hei whakaoti i te tukanga whakaputa.
