Pūnaha pouaka whakamātao, pūnaha wai whakamatao, pūnaha wai pouaka whakamātao me te pūnaha whakarewa wai paipa, flanges, takirere, papu wai me ngā ipu, me ētahi atu, i roto i te pēhanga me te pāmahana e huri haere tonu ana mō te wā roa, e te pouaka whakamātao, te pouaka whakamātao, te wai, te hau me ētahi atu waikura, ka puta tōna hanganga me ngā rauemi ki ngā nekehanga rerekē o te angiangi, te whakarerekētanga rānei, ki te whānuitanga ka puta pea te rohe o te whānuitanga o te aituā.
1. Te whakatika i te rerekētanga ā-rohe o te paipa
Hei whakakore i te āhua whakarerekētanga ā-rohe, me kimi te take mai i te hanganga me te mahi. Pērā i te putorino hauā o te pakitara rokiroki makariri nā te nui rawa o te whakarerekētanga, me whakapakari te mahi whakarewa. Mena he roa rawa te paipa, ka puta te whakarerekētanga nā te tawhiti o te whāriki, te whakairi rānei, me whakanui ake te whāriki, te whakairi rānei. Mena kāore i te nui te whakarerekētanga, kāore e pā ki te whakamahinga tonu, me tatari kia whakahoutia, kātahi ka whakatika, engari me whakapakari te tirotiro me te mahi tiaki. Mena he tino piko te ngongo, ka taea te tapahi i te wāhanga piko o te ngongo i muri i te whakawātea i te hauhautanga i roto i te ngongo, ka whakanohoia ki te whakatikatika hei whakatika. Me ōrite te pēhanga, kia puhoi hoki, kaua e whiua ki te hama, kātahi ka honoa te paipa kua whakatika ki te paipa hauā.
2. Te whakatika i ngā kapiti me ngā kōhao iti o ngā paipa
Mō ngā kapiti me ngā kōhao iti o ngā taputapu kāore i te rahi, me whakamahi te tikanga whakapiri hei whakatika. Mēnā he turuturu te whakapiri hau, kaua e neke atu i te rua ngā turuturu whakapiri, me whakakapi rānei hei whakatika i te paipa. I te wā e whakapiri ana i te pūwāhi turuturu, kāore e whakaaetia te mahi i roto i te taiao matotoru o te hau whakamatao.
3. Te whakahou i te flange
1) Tirohia te taumahatanga o ngā pūtu i te hononga o te flange, ki te mea he wetekina, whakaukia ngā nati kia ōrite te kaha ki te whakamahi i te wēti kia kore ai e tino kikī. Ki te mea kua hē te āhua o ngā pūtu, kua waikura nui rānei, me whakakapi he pūtu hou.
2) Kua waikura, kua wera rānei te hiri asbestos i te hononga flange, ā, ka ngaro te kaha hiri, me whakakapi ki tētahi hiri hou. I mua i te whakakapinga i te hiri hou, me waru te hiri taketake, ā, me horoi ki te paraffin hei tirotiro mēnā kua waikura, kua pakaru rānei te raina hiri flange. Ki te kore he raruraru, ka taea te whakakapi ki tētahi hiri hou, me whakakīkī kia rite te āhua o ngā pūtu flange. Ki te mea he kino te waikura o te mata hiri o te flange, he kino rānei ki te raina hiri, ka taea te whakakapi i te flange hou, te whakatika rānei i ngā mea kua tohua, kātahi ka tāuta ki te hiri hou hei ārai i te turuturu.
3) Kāore i te piri te hononga whakarewa, me whakatika te whakarewa.
4) Mena ka piko te flange nā te whakarewa, ā, kāore e tutuki i ngā whakaritenga huihuinga, me tahuri, me tukatuka, me whakakapi rānei.
5) I te tukanga tāutanga, ki te kore e ōrite te rārangi pokapū o ngā flanges e rua, kāore hoki e ōrite te tauira o te mata pa, me tapahi te paipa ka whakarewa anō.
4. Te whakatikatika i te takirere
1) Te whakakapinga o te takai. Ko te mahi matua o te takai he ārai i te turuturu o te rauemi mahi i te taha o te kakau takirere me te whakatū. Mēnā he turuturu iti, me whakakī te repe takai, pērā i te turuturu kāore e taea te ārai, me whakakapi te takai. Me whakawiri te whakakapinga o te kakau takirere ki waho ki te pito, me te pine takai ki te takai tawhito ki waho, kātahi ka rite ki te whakawiri i te takai hou kia rite, kātahi ka whakakī te repe.
2) Whakatikahia te pōkai. I roto i ngā kaupapa hauhautanga me te pouaka whakamātao, ina nui te diameter o te takirere, ka whakawhirinaki te pōkai ki tētahi paparanga o te hiri koranu kua whakamātaotia, te hiri kirihou fluorine rānei. Kei muri o te pōkai anō hoki he paparanga o te koranu kua whakamātaotia, kia taea ai te hiri i te rauemi me te kore e turuturu ki waho i te taha o te kakau takirere ina whakawirihia te kakau takirere ki raro.
Ina wetewetehia te takirere, whakatikahia te kakau takirere kia kore ai e pakaru, kātahi ka whakakapia te takai o te koranu kua whakamātaotia, ā, i te wa ano, me huri hoki te nohoanga takirere, kia piri ai te takai me te nohoanga o te takirere.
Mō te takai rino iti, parahi rānei, ka whakawhirinaki te hiri o tēnei takai ki tētahi rārangi whakapiri whakarewa hei whiwhi i te mea e kiia nei ko te hiri raina. Nā te mea he hiri raina, nō reira me huri marie te nohoanga o te takai me te takai kia pai ake ai te hiri.
Kia oti te whakatikatika i te takirere, me rite ki ngā whakaritenga e tika ana mō te whakamātautau ātete hau.
He rite tonu te pūnaha whakamatao i roto i te whakatikatika i te takirere haumaru ki te mea i runga ake nei, engari nā te ngohengohe o te koranu kua whakamātaohia, he maha ngā wā nā te nui rawa o te pēhanga me te mahi a te takirere haumaru i muri i tētahi wā, he uaua ki te hoki ki tōna tūranga taketake, nō reira, ina heke te pēhanga ki te pēhanga kati, kāore tonu te kati e piri. Hei whakakore i tēnei hapa, kua whakakapia ētahi hua ki te koranu koranu nickel-chromium-titanium (mārō), ki te polytetrafluoroethylene rānei.
