Te Tāutanga o ngā Mita Rere Hikohiko

Ka pā tika te kounga o te tāutanga o ngā mita rere hikohiko ki te tika me te pumau o te ine. Kei raro nei ngā tikanga tāutanga me ngā whakatūpato taipitopito:

1. Te Whakarite i mua i te Tāutanga

1.1 Kōwhiringa Pae

• Āta karohia ngā wāhi e kaha ana te wiri; ki te nui te wiri, he pai ake te tāuta i te momo wehewehe.
• Kia matara atu i ngā taputapu e whakaputa ana i ngā mara hiko hiko kaha, pērā i ngā motuka nui me ngā whakawhiti hiko.
• Me whakarite kia māmā te tirotiro, te whakahaere, me te tiaki i te wāhi tāutanga.

1.2 Tirotiro Āhua o te Paipa

• Me whakakī katoa te paipa inehia ki te wai; kaua e tāuta ki te wāhi teitei rawa o te pūnaha paipa, ki roto rānei i ngā paipa poutū kei reira te ahunga rere mai i runga ki raro me te pito tuwhera, takoto kau. Mō ngā paipa e ngāwari ana ki te whakakī hapa, tāutahia te mita ki te wāhi iti o te paipa āhua-U.
• Me maeneene te pakitara o roto o te paipa (kaua e kitea he koretake), me te ma (karekau he paru, he onepū rānei) i mua i te tāutanga.

2. Tukanga Tāutanga

2.1 Hononga Paipa

• Ko ngā mita rere hikohiko ka honoa ki ngā paipa mā roto i ngā flanges. Me whakarite kia ōrite te mita ki te tuaka o te paipa kia kore ai e rerekē, e piko rānei.
• Tāutahia ngā wāhanga paipa tika e hiahiatia ana: kaua te wāhanga paipa tika o runga e iti iho i te 10 ngā wā o te diameter o te paipa (DN), me te wāhanga o raro kaua e iti iho i te 5×DN, kia pumau ai te rere o te wai, kia pai ake ai te tika o te ine.
• Tāutahia ngā takirere kati (ki runga) me ngā takirere ārai (ki raro) hei whakahaere i te tiaki me te whakahaere.

2.2 Maimoatanga Whenua

• Whakatutukihia te hononga ōrite i waenga i te whare mita, te wai inehia, me ngā parirau paipa, ā, whai muri ko te whakapūmau tika i te whenua.
• Mō te tāutanga ki ngā paipa whakarewa (me te kore he arai ārai i te pakitara o roto), ka taea te whakawhenua tika. Mō ngā paipa kirihou, ngā paipa rānei he arai ārai, tāutahia ngā mowhiti whakawhenua, ngā āputa whakawhenua, ngā paipa poto rānei me ngā irahiko whakawhenua i ngā pito e rua o te pūoko.

2.3 Waea

• Honoa ngā waea whakaoho me ngā waea tohu i waenga i te tuku me te pūoko kia mau ai te hononga pai, kia kore ai hoki e motu, e poto rānei ngā ara iahiko.
• Me ara motuhake ngā waea tohu mai i ngā raina ngaohiko teitei, ā, me pupuri kia matara atu i ngā papa aukume me ngā pūtake wiri kaha hei whakaiti i te pokanoa o te tohu.
• Mō ngā mita rere hikohiko whakauru, tāutahia te SENSORPROM me te ahunga whakauru me te teitei tika kia taea ai e te tuku te pānui i ngā raraunga pūoko i runga i te tikanga noa.

3. Tirotiro i muri i te Tāutanga

3.1 Tirotiro Whānui

3.2 Tirotiro Whakakā-Hiko

3.3 Te Whakatikatika Rere
