He maha ngā whakamātautau ka pā ki te takirere pūrerehua mai i te hanga ki te tuku hei whakarite i tōna kounga me tōna pono. Ka hipokina e te tirotiro whānui ngā tūemi paerewa pēnei i te rauemi, te paninga, te āhua, te rapa, te pēhanga, me ngā ine, tae atu ki te mahi hiri, te āhua, te taipana, te pakeke, te matotoru, te huihuinga, te tika o te miro me te flange, me ngā tohu whai.
Ka taea te whakahaere i te tukanga tirotiro i tēnei raupapa: Tirotiro rauemi mata → Tirotiro tukatuka → Whakamātautau mahi hua kua oti → Whakaaetia whakamutunga. Ka whakamāramahia ia āhuatanga me ngā tikanga me ngā paerewa motuhake.
Te Tukanga Tirotiro i te Takirere Pūrerehua
1. Tirotiro Rauemi Mata

1.2 Ngā Tuemi Tirotiro:
-Tātari Hanganga Matū: Mā te whakamahi i te ine ā-rorohiko, i te tikanga tātari matū rānei, manatokohia te tiwhikete rauemi hei whakaū i te tutuki i ngā paerewa rauemi ASTM/GB/EN.
-Whakamātautau Mahi Ā-Mīhini: Ka whakahaerehia te tauira mō ngā whakamātautau kume, hua, roa, me te pānga.
-Te Tāututanga Rauemi me te Whai Aroturuki: Me tāutuhia ia puranga rauemi mata mā te tau oumu hei whakarite kia taea te whai i te pūtake.
- Tirotiro Whakarewa (Whiringa): Tirohia ngā whakarewa mō ngā hapa pēnei i te whakaurunga para me te pūngao.
2. Tirotiro Ahu

Te mokowā o te kōhao hononga flange, te diameter o te kōhao, te whakatakotoranga miro
Te matotoru o te pereti takirere me te ātea o te taha
Te hohonutanga o te miro me te manawanui
3. Tirotiro Rapa me te Nohoanga
Ngā Rauemi Noa: EPDM, NBR, VITON, PTFE.
3.1 Kaupapa
Hei whakarite i te ātete ki te pēhanga, ki te pāmahana, me te ātete ki te waikura o ngā rauemi hiri.
3.2 Ngā Tuemi Tirotiro
Whakaū Rauemi
Tirohia te maeneene o te mata, te ngaro o ngā pūwero, ngā mirumiru, me ngā poke.
Tirohia ngā āhuatanga matua o te mowhiti hiri, pērā i te diameter whakawhiti-wāhanga me ngā diameter o roto, o waho hoki.
Te pakeke o te rapa (Te whakamātautau pakeke o te takutai), te huinga pēhanga, te kaha kume, me ētahi atu.
Whakamātautau ātete ki te pakū
Te taunga me te pono o te pereti takirere
4. Tirotiro Paninga
4.1 Kaupapa
Hei whakarite kia tutuki i ngā paerewa te ātete ki te waikura, te piri, me te matotoru o te paninga.
4.2 Ngā Tuemi Tirotiro
Te maimoatanga mata i mua i te mata (tango waikura) te taumata i mua i te rehu (Sa2.5, neke atu rānei, kāore he unahi, he waikura rānei e kitea ana)
Te matotoru o te paninga i muri i te rehu (mā te whakamahi i te ine matotoru o te paninga)
Te piri o te paninga (whakamātautau tapahi whakawhiti, te mokowā 1mm, te horahanga tango paninga ≤5% i muri i te tango rīpene)
Te tirotiro āhua (ngā piko, ngā kōhao iti, ngā mirumiru, te kiri karaka, te rerekētanga o te tae)
Te whakamātautau pakeke o te paninga me te ātete ki te waikura i te rehu tote
5. Whakamātautau Pēhanga me te turuturu
5.1 Kaupapa
Hei whakarite kia kore te takirere e turuturu i raro i te pēhanga kua whakatauria.
5.2 Ngā Paearu Whakaae
Kaua te tinana takirere me ngā wāhanga katoa e mau ana i te pēhanga e pakaru te hanganga, e rerekē te āhua tuturu, e turuturu rānei.
5.3 Ngā Tuemi Whakamātautau
Whakamātautau Kaha Anga: Whakamātautau waipū i te 1.5 ngā wā pēhanga whakatauranga, te wā pupuri ≥ 2 meneti.
Whakamātautau Hiri: Whakamātautau hiri whakamua me te whakamuri i te 1.1 ngā wā pēhanga whakatauranga.
Whakamātautau Ātete Hau: Kitea te turuturu moroiti mā te whakamahi i te hau, te hauota rānei i te 0.6 MPa.
Paerewa Kore-Tuku: E tutuki ana i ngā whakaritenga API 598 / ISO 5208.
6. Whakamātautau Taipana Whakahaere
6.1 Kaupapa
Hei manatoko mēnā e tutuki ana te taipana whakatuwheratanga me te katinga i te paerewa, ā, kei roto hoki i ngā whakaritenga hoahoa, me whakarite kia ōrite te waeine taraiwa.
Tikanga Whakamātautau
Inehia mā te whakamahi i ngā kī taipana me ngā mita taipana pēnei i ngā kaiwhakaoho hiko; whakatairitehia te taipana hoahoa ki te taipana i inehia.
7. Tirotiro Tirohanga me te Tohu
7.1 Kaupapa
Hei whakarite i te kounga o te āhua me ngā whakatakotoranga tohu.
7.2 Ngā Tuemi Whakamātautau
Kāore he kongakonga rino, he para whakarewa, he paru hinu, he poke rānei i roto.
Kāore he ngatata, he pūwero, he waikura rānei. He maeneene te mata me te ōritetanga o te tae. He mārama, he oti, he haumaru hoki ngā mōhiohio e pā ana ki te papa ingoa (tauira, whakatauranga pēhanga, rauemi, pere ahunga rere).
8. Whakamātautau Mahi
8.1 Kaupapa
Hei manatoko i te pono me te rere o te takirere.
8.2 Ngā Tuemi Whakamātautau
Te ngāwari o te whakatuwhera me te kati i te pereti takirere
Te tika o te tūnga o te takirere
Te ine i te tauwehenga ātete rere (uara Cv)
Te ōritetanga o te ahunga rere wai
9. Tirotiro Whakamutunga me te Tirotiro Wheketere
9.1 Kaupapa
Hei whakatau whānui mēnā he tika te hua, ā, kua rite mō te tuku.
9.2 Kei roto
Arotake i ngā tuhinga whakamātautau
Te whakapiri i te tiwhikete whakaritenga me ngā tapanga whakamātautau
Mēnā rānei he pai te tiaki a te takai i ngā kino i te wā e kawe ana, ā, mēnā he taupoki tiaki kei te mata o te flange me ngā pito miro.
