Te tātari i ngā whakaritenga hangarau me ngā kaupapa matua mō te tāutanga o te whakaiti tauhou i roto i te pūnaha papu ahi.
1. Ngā whakaritenga whirihoranga o ngā wāhanga paipa putanga
E ai ki ngā whakaritenga whakahau o te GB50261 "Waehere mō te Hanga me te Whakaae i te Pūnaha Tauhiuhi Aunoa":
Whirihoranga Wāhanga Matua:
● Me tāuta he takirere tirotiro (he takirere whakahaere papu maha-mahi rānei) hei ārai i te rere whakamuri o te reo
● E hiahiatia ana he takirere whakahaere hei whakahaere i te rere
● Te aroturuki takirua i te ine pēhanga mahi me te ine pēhanga o te paipa putanga matua o te pūnaha
Ngā Whakaritenga Aroturuki Pēhanga:
● Me whai taputapu ārai te ine pēhanga (e taunakitia ana te ārai diaphragm)
● Kua tāutahia te takirere mono ki mua i te taputapu ārai hei whakahaere ngāwari
● Te whānuitanga o te ine pēhanga: 2.0-2.5 ngā wā o te pēhanga mahi o te pūnaha
2. Ngā aratohu tāutanga mō ngā taputapu whakahaere wai
Ngā Whakaritenga Aronga:
● Me tino rite ngā takirere tirotiro/takirere whakahaere maha-mahi ki te ahunga o te rere o te wai
● E taunakihia ana te hononga flange kia mau ai te piri
Ngā taipitopito tāutanga mō te ine pēhanga:
● Me whakamahi ngā rauemi ātete-waikura (te maitai kore waikura 304, te koranu parahi rānei) hei taputapu ārai
● Me 1.2-1.5m te teitei o te mahi o te takirere mono mai i te whenua
3. Kaupapa arotau o te pūnaha paipa momi
Whirihoranga pūrere tātari:
● Me whai tātari kete te paipa momi (rahi o ngā pūwero ≤3mm)
● Me whakauru he taputapu whakaoho pehanga rerekētanga ki te tātari
I hangaia kia māmā ake te tiaki:
● Me whai paipa karo me te atanga horoi tere te tātari
● E taunakihia ana te hanganga tātari wetewete
4. Ngā mahi tiaki mō ngā āhuatanga waipēhi
Kōwhiringa whakaiti rerekē:
● Me whakamahi ngā whakaiti pēhi paerewa (e ai ki te SH/T 3406)
● Me ≤8° te koki o te whakaiti hei ārai i ngā huringa ohorere o te ātete ā-rohe
Arotau Rere:
● Ko te roa o te wāhanga paipa tika i mua me muri i te whakaiti me ≥ 5 ngā wā o te whānui o te paipa
● E taunakihia ana ngā whakatauira CFD hei manatoko i te tohatoha tere rere
5. Ngā whakatūpato mō te whakatinanatanga o te kaupapa
Whakamātautau ahotea:
● Me 1.5 ngā wā o te whakamātautau pēhanga pūnaha i te pēhanga mahi
● Kāore e iti iho i te 2 hāora te roa o te pupuri
Te Tikanga Horoi:
● Me whakahaere te whakakorenga o te pūmua i mua i te tāutanga o te pūnaha
● Me ≥ 1.5m/s te tere o te rere o te wai
Ngā Paearu Whakaae:
● Kaua te taumata tika o te ine pēhanga e iti iho i te 1.6
● Me ≤ 0.02MPa te pēhanga rerekētanga o te tātari
6. Kua whakaurua tēnei pūnaha whakatakotoranga ki roto i te "Ngā Whakatakotoranga Hangarau mō te Tuku Wai Ahi me ngā Pūnaha Wai Ārai Ahi" GB50974, ā, e taunakihia ana kia whakahaerehia te tātaritanga HAZOP me ngā kaupapa motuhake, me te arotahi ki ngā āhuatanga mōrearea e whai ake nei:
● Te mōrearea o te rerenga whakamuri o ngā pāpāho nā te korenga o ngā takirere tirotiro
● Te tūponotanga o te pakaru o te puna wai nā te mea kua purua ngā tātari
● Te mōrearea o te mahi pēhanga nui rawa atu nā te ngoikore o te ine pēhanga
● Te mōrearea o te ru waipēhi i puta mai i te tāutanga hē o ngā whakaiti
E taunakihia ana kia whakamahia he kaupapa aroturuki matihiko, kia whirihorahia ngā pūoko pēhanga, ngā aroturuki rere me ngā tātari wiri, ā, kia whakatūria he pūnaha whakahaere rūma papu ahi atamai hei whakatutuki i te aroturukitanga tūnga me te whakatūpato hapa i te wā tūturu.
