4. Te ariā mahi
Ka tuwhera, ka kati aunoa te taki takirere i te kōpae kia kore ai e rere whakamuri te reo ma te rere waenga.
5. Ko nga paerewa paera e tika ana engari kaua e iti ki:
（1）API 6D-2002（2）ASME B16.5-2003
（3）ASME B16.10-2000 （4）API 598-2004

6. Rokiroki & Tiaki & Whakanoho & Mahi
6.1 Me penapena te takirere ki roto i te rūma maroke me te hau pai .me hono nga pito o te huarahi ki nga uhi.
6.2 Me tirotirohia me te horoi i nga wa katoa nga whao kei raro i te rokiroki mo te wa roa, ina koa ko te kanohi nohoanga kia kore ai e pakaru, me whakakikoruatia te mata o te nohoanga ki te hinu aukati waikura.
6.3 Me tirohia te tohu takirere kia rite ki te whakamahi.
6.4 Me tirotirohia te kohao o te takirere me te mata hiri i mua i te whakaurunga me te tango i te paru mena kei reira.
6.5Kia rite te ahunga pere ki te ahunga rere.
6.6 Me whakauru poutū te arataki kōpae taki takirere ki te paipa. Ko te hiki i te pihanga taki kōpae whakapae me whakanoho whakapae ki te paipa.
6.7 Me tirotirohia te wiri me te whakarereke i te pehanga reo paipa kia kore ai e pa te wai.
- Nga raru pea, nga take me nga tikanga whakaora
| Nga raruraru pea | Nga take | Ine Whakatikatika |
| Kaore e taea e te kōpae te whakatuwhera, te kati ranei |
| |
| Leakage |

8. Pūtāhui
I muri i te whakamahi i te takirere, ko te wa whakamana o te takirere he 12 marama, engari kaua e neke ake i te 18 marama i muri i te ra tuku. I roto i te waa whakamana, ka whakawhiwhia e te kaiwhakanao he ratonga whakatika, mokowhiti ranei mo te kore utu mo te pakaru o te taonga, te mahi, te pakaru ranei mena ka tika te mahi.
