I. Ngā Painga Matua

1. Tāutanga Māmā, Ā, Whai Hua, He Pai mō ngā Horopaki Ā-Wāhi-He iti

   Kāore e hiahiatia he whakapiringa uaua mō ngā flange. Ka taea te whakaoti i te tāutanga mā te whakawiri noa me te whakamau ki te atanga miro kua rāhuitia o te paipa, ka taea te whakahaere e te tangata kotahi, ka penapena nui i te wā hanga. He tino pai mō ngā wāhi whaiti, ngā taputapu e mau ana ki te pakitara, ngā whakahoutanga paipa rānei, ā, he maha ngā wā e whakamahia ana e ngā kiritaki o tāwāhi i roto i ngā raina whakaputa iti me ngā taputapu taiwhanga.

2. He pai rawa te mahi hiri, te whakaiti i ngā tūponotanga turuturu

   Ina whakamahia me ngā wāhanga hiri pēnei i te rīpene hiri miro PTFE me ngā gaskets, ka piri pai te mata pa o te hononga miro, ka taea te ārai i te turuturu o ngā wai kawe hiko (hei tauira, ngā otinga waikawa-pūtake, te paru). Ki te whakaritea ki ngā hononga flange, ka tukuna e ngā hononga miro he mahi hiri pumau ake i raro i ngā āhuatanga pēhanga iti, ā, kāore e ngāwari te pānga hiri i te wā e wetewetehia ana, e huihuia anōtia ana.

3. Te Tika o te Ine Teitei mō ngā Kaitiri Iti, te Ngaronga Pēhanga Iti

   Ko ngā mita rere hikohiko hononga miro e wātea ana i roto i ngā kāpara mai i te DN10 ki te DN50. I roto i tēnei whakatakotoranga, he hanganga kiato te pūoko, e whakarite ana i te papa rere wai pumau i te wā e toia ana, e whakaiti ana i ngā ia hurihuri me te tere rere kore taurite, ā, ka whakapai ake i te tika o te ine. I taua wā, kāore he pūwero tāpiri (pēnei i ngā pūtu flange) i runga i te pakitara o roto o te paipa, ka hua ake he iti te ātete wai me te ngaronga pēhanga, e pai ai mō ngā horopaki me ngā whakaritenga whakahaere whakapaunga pūngao.

4. Utu Whakahaere, Te Urutau ki ngā Hokonga Puranga-Iti

   He māmā noa te hanganga o te tinana takirere me ngā wāhanga hono o ngā hononga miro, ā, he iti ake ngā utu hanga i ngā hononga flange, ka pai ake te whakataetae o te utu hua. Hei tāpiri, he iti noa te rahinga ota iti rawa (MOQ) mō ngā mita rere hikohiko miro iti-rahi, e tutuki ai ngā hiahia ota whakamātautau o ngā kiritaki iti o tāwāhi, ā, ka noho hei tauira rongonui mō te whakatairanga hokohoko ki tāwāhi i te wāhanga tuatahi.

II. Ngā Herenga o te Tono

1. He mea here e te Caliber me te Pressure, Kāore mō ngā horopaki Rere-Tiketike me te Pēhanga-Tiketike

   Nā te kaha o te miro me te mahi hiri, ko te rahinga mōrahi o ngā mita rere hikohiko me ngā hononga miro kāore e neke ake i te DN50, ā, ko te pēhanga mahi kei roto i te nuinga o te wā i te PN1.6 – PN4.0MPa. Kāore e taea te whakatutuki i ngā whakaritenga o ngā paipa whānui ahumahi (hei tauira, i runga ake i te DN100) me ngā paipa pēhanga teitei (hei tauira, ngā putanga o ngā tauhohenga matū pēhanga teitei), nō reira e taunakihia ana kia whakamahia ngā hononga flange, ngā hononga rawhi rānei.

2. Te Whakaritenga Nui mō te Hononga Paipa i te Wā Tāutanga

   Mena he rerekē te paipa, he piko rānei te atanga miro i te wā e whakamau ana i te tīwiri, ka pā pea te kaha kore taurite ki te pūoko, ka pā kino ki te tika o te ine, engari ka kino hoki te atanga miro. I te wā tāutanga, me whakarite kia ranea ngā wāhanga paipa tika o runga (10D) me raro (5D), ā, me waiho te pūoko kia matara atu i ngā pūtake wiri pēnei i ngā papu me ngā takirere.

3. Te Tiaki me te Wetewete i te Wāhi e Herea ana e te Wāhi

   Mena ka waikura, ka piri rānei te wāhanga hononga miro i muri i te whakamahinga roa, me whakamahi taputapu motuhake hei wetewete, he mea uaua ki te whakahaere i roto i ngā paipa whaiti. Ki te whakatauritea ki te wetewete pūtu o ngā hononga flange, he ngoikore ake te ngāwari tiaki o ngā hononga miro, inā koa i roto i ngā rauemi he kaha te waikura, me tirotirohia tonutia te āhua o te miro.

III. Ngā Tohu Tāpiri Matua mō te Urutau Tauhokohoko ki Tāwāhi

1. Te Whakarerekētanga Rauemi ki ngā Āhuatanga Mahi o te Ao

   Ka taea te whakarite i ngā rauemi o te atanga miro kia rite ki ngā paerewa reo me ngā paerewa ā-rohe a te kiritaki. Ko ngā rauemi ātete-waikura noa pērā i te maitai kore waikura 316L me te Hastelloy ka whakamahia hei whakatutuki i ngā whakaritenga rauemi a ngā kiritaki Pākehā me Amerika i roto i ngā ahumahi matū me te kai. Mō ngā āhuatanga he kounga wai teitei, ka taea hoki te whakarato i ngā atanga miro maitai waro hei whakahaere i ngā utu.

2. Te Whakatutuki i ngā Paerewa Miro o te Ao

   He rerekē ngā paerewa miro i ngā rohe o tāwāhi, nō reira me whakaū i ngā hiahia o te kiritaki i mua: Ko te nuinga o ngā kiritaki o Ūropi e whakamahi ana i te BSPP (British Standard Pipe Parallel), ko ngā kiritaki o Amerika Te Raki ia e pai ake ana ki te NPT (National Pipe Taper). Me mārama te tohu i ngā paerewa e tika ana i roto i te pukapuka hua hei karo i ngā raruraru hototahi tāutanga.
