I roto i te rāngai ahumahi tino whanake me te whakahaeretia o Ūropi, ko te mahi, te pono, me te tutuki i ngā whakaritenga o ngā rauemi te mea nui rawa atu. I roto i ngā rauemi tino nui, ko te ngongo maitai kore hononga EN 10216 S355J2H, e mōhiotia ana mō ōna āhuatanga whānui tino pai, kua waiho hei whiringa pai i roto i ētahi ahumahi matua, mai i te hanganga pūngao ki te hanga mīhini taumaha. Ka tūhuratia e tēnei tuhinga ngā āhuatanga o tēnei maitai, ngā paerewa e whaihia ana e ia, me ōna tono whānui i roto i te mākete Ūropi.

Te Mārama ki te Paerewa me ngā Rauemi: EN 10216 me S355J2H

Tuatahi, he mea nui kia mārama ki te tikanga o tōna ingoa:

•EN 10216: He raupapa paerewa Pākehā tēnei e tohu ana i ngā tikanga tuku hangarau mō ngā ngongo maitai kore hononga mō ngā take pēhanga. Mā tēnei paerewa ka mau tonu ngā āhuatanga hangarau o ngā ngongo i ngā pāmahana teitei, ā, ka pai ai mō ngā taputapu pēhanga. Kua whakakapia ngā putanga hou e ngā wāhanga pēnei i te EN 10216-1 me te EN 10216-2, engari kua nekehia te taumata S355J2H me ōna whakaritenga.

•S355J2H:

◦S: Ko tōna tikanga he "Hanganga Rino".

◦355: E tohu ana i te kaha whakaputa iti rawa o te 355 Megapascals i te pāmahana rūma, ko te tikanga he ātete pai ki te whakarerekētanga me te kaha ki te kawe kawenga.

◦J2: E tohu ana i te taumata pakari o te pānga. E tohu ana ko te whakamātautau pānga Charpy V-notch e whakahaerehia ana i te -20°C, ā, e tutuki ana i ngā whakaritenga mimiti pūngao motuhake. Mā tēnei ka mau tonu te ātete pai o te rauemi ki te pakarukaru ahakoa i roto i ngā taiao makariri, he mea nui mō ngā whakaurunga o waho i ngā rohe pēnei i a Ūropi ki te Raki.

◦H: Ko te tikanga tēnei mō te "Āhua Kua Whakaōritea". Ko te tikanga kua pāngia te ngongo maitai e te maimoatanga wera whakaōrite hei whakapai ake i te hanganga o te kōpaka, hei whakapai ake i te hanganga moroiti, ā, hei whakarei ake i ōna āhuatanga hangarau me tōna pakari, kia ōrite ake ai, kia pumau ake ai.

Hei whakarāpopototanga, ko te EN 10216 S355J2H he ngongo maitai tuimotu kua whakatauritea, he kaha teitei, he pakari pāmahana iti pai, he pono hoki, he mea hanga motuhake mō ngā taiao pēhanga me te ahotea nui.

Ngā Wāhi Whakamahinga Matua i te Mākete Pākehā

Nā ngā āhuatanga o ngā ngongo S355J2H he mea tino pai mō ngā tono nui mō te haumaru, te whai hua, me te pumau i roto i te ahumahi Pākehā. Ko ngā wāhi matua o ā rātou tono ko:

1. Te Rāngai Pūngao me te Hiko

•Hinu me te Hau: Whakamahia i roto i ngā paipa tukatuka, ngā raina kohikohi, ngā oko pēhanga, me ngā ngongo poiha mō ngā papaaho o uta me te moana. He mea nui tōna ātete ki te pēhanga me te mahi pāmahana iti mō te whakahaere i ngā warowaihā mura me ngā pahū.

•Te Mana Wera me te Whakamahana Rohe: He whānuitia te whakamahinga i roto i ngā whakamahana nui, ngā whakamahana anō, me ngā ngongo economizer mō ngā poiha o ngā teihana hiko, tae atu ki ngā raina matua mō ngā pūnaha whakamahana rohe o te tāone. Ka taea e ia te tu atu i ngā pānga roa o te mamaoa pāmahana teitei me te pēhanga teitei.

•Pūngao Whakahou: E hiahiatia ana hoki ēnei paipa pēhanga i roto i ngā tipu hiko koiora me ētahi kaupapa waiariki.

2. Hanganga me ngā Hanganga

•Ngā Whakamahinga Hanganga Taumaha: Whakamahia mō ngā pou tautoko me ngā hanganga matua e mau ana i ngā kawenga i roto i ngā whare nunui pēnei i ngā papa tākaro, ngā taunga rererangi, ngā piriti, me ngā whare ahumahi. Nā tōna kaha nui ka taea te hoahoa i ngā hanganga mama engari he pakari ake.

•Mīhini Hanga: Hei oko rango waipēhi me ngā wāhanga hanganga mō ngā taputapu taumaha pēnei i ngā keri me ngā kerene, me tu atu ki ngā ahotea nui me ngā kawenga pānga.

3. Ngā Ahumahi Matū me te Tukanga

•E whakamahia ana i roto i te hanga i ngā tauhohenga, ngā whakawhiti wera, ngā pou, me ngā pūnaha paipa tukatuka i te wā e whakahaere ana ngā taputapu i ngā pāpāho waikura, kino rānei i raro i te pāmahana me te pēhanga teitei. Ko te pono me te ōritetanga o te S355J2H he mea nui hei whakarite i te mahi haumaru.

4. Ētahi atu Whakamahinga Ahumahi

•Whakamahia mō te hanga i ngā rango hau mō ngā hau kua pēhia (hei tauira, ngā hau ahumahi, te hāora hauora) i raro i ngā ture tino pakari o te EU.

•Ngā ngongo tui tino tika mō te kawe i ngā wai pēhanga teitei, hei wāhanga miihini rānei (hei tauira, ngā whare whāriki).

Ngā Take Matua e Ārahi Ana i tōna Angitu i te Mākete o Ūropi

1. Te Whakatutukitanga me te Haumarutanga o ngā Ture: He tata te hononga o te paerewa EN 10216 ki te European Pressure Equipment Directive (PED 2014/68/EU). Ko te whakamahi i ngā rauemi e rite ana ki tēnei paerewa he whakaritenga matua mō ngā kaihanga ki te whakanoho ture i ngā taputapu ki te mākete Pākehā, ā, ko S355J2H te tohu pakari mō te tutuki i ngā whakaritenga.

2. Ngā Āhuatanga Mīhini Tino Pai: Mā te huinga tino pai o te kaha me te pakari ka taea te aro atu ki ngā āhuatanga āhuarangi kanorau o Ūropi me ngā taiao ahumahi uaua.

3. Kounga me te Aroturuki: He mea nui ki ngā kaihanga me ngā kaiwhakamahi o Ūropi te whakapumautanga kounga. Ko te paerewa EN 10216 e whakahau ana i te mana whakahaere whakaputa, te whakamātautau, me te tiwhikete tino pakari, kia mau tonu ai te kounga pai me te aru katoa mō ia puranga rauemi.

4. Te mekameka tuku me te tohungatanga pakari: E whakamanamana ana a Ūropi ki ngā kaihanga ngongo maitai matua o te ao (pērā i a Tenaris, Vallourec, me ētahi atu he nui te kitea) me ngā whatunga tohatoha, ka taea te tuku pumau i ngā ngongo S355J2H i roto i ngā whakaritenga rerekē me te whakarato tautoko hangarau whānui.

Whakamutunga

Ehara i te mea he taonga noa iho te ngongo maitai kore hononga EN 10216 S355J2H; koia te "uaua toto" me te "tuara" o ngā hanganga ahumahi hou o Ūropi. Ko tōna angitu i ahu mai i tētahi huinga tino pai: he pūnaha paerewa pakari a Ūropi e tautuhi ana i tōna kounga teitei, me ōna āhuatanga ā-roto o te kaha teitei, te pakari teitei, me te pono teitei e tutuki tika ana i ngā tono tino kaha o ngā rāngai ahumahi matua o Ūropi. I a Ūropi e haere tonu ana ki te haumi ki te whakawhiti pūngao, te whakapai ake i ngā hanganga, me te auahatanga hanga, ka noho tonu te ngongo maitai kore hononga S355J2H hei rauemi matua e kore e taea te whakakapi, e tautoko ana i te ahumahi o nāianei me te heke mai o Ūropi.
