Ko te tātari irahiko me te irahiko tukunga whatu (OES) e whakamahia whānuitia ana hei manatoko kei te tutuki i ia puranga te hanganga e hiahiatia ana.

2. Te Whakamātautau i te Kaha Kume me te Āhuatanga Mīhini

Ko te whakamātautau miihini tētahi o ngā mahi tino nui, nā te mea he maha ngā wā ka mahi ngā taura waea i raro i ngā āhuatanga hihiri, taumaha rānei. Kei roto i ngā whakamātautau:

Whakamātautau Kaha Kume

Ka ine i te kaha mōrahi ka taea e te taura te tu atu i mua i te whati. Ka rerekē ngā uara i runga i te hanganga o te taura pēnei i te 1×7, 1×19, 7×7, 7×19 rānei.

Te Kaha Tuku me te Toronga

Ka manatoko i te kaha o te taura ki te totoro me te mimiti i te kaha, me te kore e huri āhua tuturu.

Te Tauwehenga o te Āhuatanga

Ka whakarite i te whanonga e matapaetia ana i raro i te taumahatanga, he mea nui mō ngā mahi hiki me ngā mahi hanganga.

Ka whakahaerehia ēnei whakamātautau mā te whakamahi i ngā mīhini kume kua whakatikatikaina ka taea te ine i ngā taura whakarewa kaha-teitei.

3. Te Diameter Waea me te Tika o ngā Ahu

He mea nui te ōritetanga o ngā āhuatanga mō te mahi tika o te taura. Kei roto i ngā tirotirohanga:

• Te ine i te diameter o ngā waea takitahi

E whakatauira ana tēnei whakamātautau i te whakamahinga o ngā kerēne, ngā ararewa, me ngā taputapu moana i te ao tūturu.

6. Whakamātautau Ātete Waikura

I te mea he whānuitia te whakamahinga o te taura waea 904L i roto i ngā taiao whai rawa i te hauhā me te waikawa, he mea nui te whakamātautau waikura. Ko ngā tikanga ko:

Whakamātautau Rehu Tote (ASTM B117)

Ka whakatauira i te pānga roa ki ngā taiao moana.

Whakamātautau Waikura Ā-Whānui

Ka whakarite i te ātete ki te pāwera i muri i te whakarewanga, i te whakamahana rānei.

Whakamātautau Waikura me te Poka

Aromatawai i te ātete ki te waikura ā-rohe i roto i ngā taiao pūmau, iti rānei te hāora.

Mā ēnei whakamātautau ka whakaūtia te pai o te taura mō ngā mahi tai, matū, me te moana.

7. Whakamātautau Matūriki Aukume me te Au Eddy

Ahakoa te kore-aukume o te maitai kore-waikura i te nuinga o te wā, tera pea ka puta he urupare aukume iti i roto i te waea 904L kua mahi matao. Mā ngā tikanga kore-whakangaro ka āwhina i te kimi i ngā hapa o roto:

• Whakamātautau matūriki aukume

• Te tirotiro i te au eddy

• Te kimi hapa orooro

Ka tautuhia e ēnei tikanga ngā whati waea, ngā whakaurunga, ngā pakaru o te matua, me ngā āhuatanga rerekē o te hanganga, me te kore e kino ki te hua.

8. Manatoko Hanganga me te Whakamātautau Taurite Taura

Ka tirotirohia te hanganga o te taura hei manatoko:

• Momo whakatakoto tika (whakatakotoranga noa, whakatakoto roa rānei)

• Te ahunga tika o te miro me te ōritetanga

• Taurite taura i raro i ngā kaha takahuri

• Te korenga o te nekehanga o te whenu, te kore rānei o te tūnga tika

• Te pono o ngā taura me ngā matua muka, ngā matua kowiri tira rānei

He mea nui te whakarite i te tika o te hanganga mō ngā whakamahinga kawenga nui me te haumaru.

9. Whakamātautau Utaina Pakaru

Ko tētahi o ngā whakamātautau tino nui mō te tiwhikete, ko te whakamātautau kawenga pakaru e whai ake nei:

• Te kaha pakaru tuturu

• Te whakataurite ki te kawenga pakaru iti rawa kua whakatauria

• Tātaritanga aratau rahunga

• Te pumau o te taura i muri i te tono kume

He mea nui ngā hua o te pakaru kawenga mō te tiwhikete taputapu hiki, ā, me hangai ki ngā paerewa ISO 2408, ASTM A1023 rānei.

10. Te Tuhituhi Kounga me te Whai Aroturuki

Me whakauru i roto i ia puranga taura waea 904L:

• Ngā tiwhikete whakamātautau mira (MTC 3.1, 3.2 rānei)

• Ngā pūrongo tirotiro ine

• Ngā pūrongo āhuatanga mīhini

• Ngā hua tirotiro mata

• Ngā raraunga whakamātautau ātete waikura

• Te maha o te wera me ngā mōhiohio whai i te hanga

Mā te whai i ngā āhuatanga katoa ka tutuki te whakaritenga mai i te rauemi mata ki te taura kua oti.

Ngā tono ahumahi e hiahia ana ki te whakamātautau kounga tino pakari

Nā te uaua o ngā āhuatanga o ētahi rāngai, he mea nui te whakamātautau pakari mō ngā tono pēnei i:

• Ngā papa hinu me te hau o waho

• Ngā pūnaha hiki me te taunga moana

• Ngā taiao karihi me ngā taiao pāmahana teitei

• Ngā huihuinga taura rererangi

• Te tukatuka rongoā me te kai parakore teitei

I roto i ēnei tono, ahakoa ngā hapa iti noa, ka raru pea te haumaru me te utu nui mō te wā kore mahi.

Me pēhea te whakarite a sakysteel i te kounga teitei o te taura waea 904L

Hei kaiwhakarato pono mō ngā rauemi kowiri tira me te koranu nikara, ka whai a sakysteel i ngā paerewa o te ao kia pai ai te kounga o tana taura waea 904L. Ko ngā mahi matua ko:

• Te whakamahi i te waea mata parakore teitei e tutuki ana i ngā whakaritenga ASTM me ISO

• Te whakahaere i te tirotiro 100 ōrau o te hanganga matū

• Te whakatinana i ngā tukanga kukume waea me te here taura matatau

• Te whakahaere i ngā whakamātautau miihini tae atu ki ngā whakamātautau kume, piko, me te ngenge

• Te whakarite i te kounga o te mata mā te hangarau tirotiro whatu

• Te whakarato i ngā tuhinga MTC katoa me te whai i ngā tuku katoa

Mā ēnei mahi ka oati ngā kaihoko ka whiwhi taura waea ka taea te mahi pono i roto i ngā taiao ahumahi tino kino.

Whakamutunga

He mea nui ngā whakaritenga tirotiro me te whakamātautau kounga mō te taura waea 904L hei whakapūmau i te mahi roa, te hanganga pai, me te haumaru i roto i ngā taiao uaua. I te pikinga ake o te whakamahinga o te 904L i roto i ngā ahumahi moana, matū, me te parakore teitei, kua noho hei mea nui ngā tukanga whakamātautau pakari hei whakarite kia tutuki i ia taura ngā tumanakohanga o te ao. Mā te piri ki ngā paerewa o te ao me te whakatinana i te hangarau tirotiro matatau, kei te haere tonu ngā kaiwhakarato pēnei i a sakysteel ki te whakarato i te taura waea 904L mahi teitei e tautoko ana i ngā kaupapa hangarau o te ao me te pono me te maia.
