Ko te kaupapa mahi me te hanganga me ngā wāhi tāutanga o te takirere pūrerehua noho rapa

Tetakirere pūrerehua noho rapahe momo takirere e whakamahi ana i tētahi pereti pūrerehua porowhita hei wāhanga whakatuwhera me te kati, ā, ka hurihuri tahi me te kakau takirere hei whakatuwhera, hei kati me te whakarite i te awa wai. Ko te pereti pūrerehua o tetakirere pūrerehua noho rapakua tāutahia ki te ahunga diameter o te paipa. I roto i te hongere porotaka o tetakirere pūrerehua noho rapatinana, ka huri te pereti pūrerehua āhua-kōpae i te tuaka, ā, ko te koki hurihanga kei waenganui i te 0° me te 90°. Ina huri ki te 90°, kua tuwhera katoa te takirere.

Ngā wāhi hanga me te tāutanga

1. Me tutuki i te tūranga tāutanga, te teitei, me te ahunga o te kawemai me te kaweake ngā whakaritenga hoahoa, ā, me pūmau, me piri hoki te hononga.

2. Mō ngā momo takirere ā-ringa katoa e tāutahia ana ki te paipa whakamahana wera, kaua te kakau e anga ki raro.

3. Me tirotiro ā-kanohi i mua i te tāutanga o te takirere, ā, me tutuki te papa ingoa o te takirere i ngā whakaritenga o te paerewa ā-motu o nāianei "Tohu Takirere Whānui" GB12220. Mō te takirere he nui ake te pēhanga mahi i te 1.0MPa, ā, he wāhi nui ki te tapahi i te paipa matua, me whakahaere te whakamātautau kaha me te mahi piripono i mua i te tāutanga, ā, ka whakaaetia kia whakamahia i muri i te whakamātautau. I te wā o te whakamātautau kaha, ko te pēhanga whakamātautau he 1.5 ngā wā o te pēhanga ingoa, ā, ko te roanga kaua e iti iho i te 5 meneti. Me tohu te whare takirere me te takai me te kore e turuturu. I te whakamātautau piripono, ko te pēhanga whakamātautau he 1.1 ngā wā o te pēhanga ingoa; me tutuki te pēhanga whakamātautau i ngā whakaritenga o te paerewa GB50243 i te wā o te whakamātautau, ā, ka tohua te mata hiri kōpae takirere mēnā kāore he turuturu.

Ngā wāhi whiriwhiri hua

1. Ngā tawhā whakahaere matua o tetakirere pūrerehua noho rapako ngā whakatakotoranga me ngā rahinga.

2. Ka taea te whakahaere ā-ringa, mā te hiko, mā te reti rānei, ā, ka taea te whakamau i tētahi koki i roto i te awhe 90°.

3. Nā te mea he kotahi te pou me te pereti takirere kotahi, he iti te kaha o te pikaunga, ā, he poto te roa o te ora o te takirere i raro i ngā āhuatanga o te rerekētanga pēhanga nui me te tere rere nui.
