He aha te NACE MR0175?

Ko te NACE MR0175, e mōhiotia ana ko "Ngā Whakaritenga Rauemi Paerewa mō te Ātete ki te Pakaru o te Āhuatanga o te Sulfide i roto i ngā Taiao Whakamaeneene Hinu Waikura," he paerewa i whakawhanakehia e te National Association of Corrosion Engineers (NACE) hei aro atu ki te take o te pakaru o te ahotea sulfide i roto i te umanga hinu me te hau. Ka whakaratohia e tēnei paerewa he aratohu mō te whiriwhiri me te tohu i ngā rauemi e whakamahia ana i roto i ngā taputapu me ngā wāhanga ka pāngia e ngā taiao waikura i roto i ngā mahi whakamaeneene hinu.

Ko te pakarutanga ahotea whanariki (SSC) he momo pakarutanga i puta mai i te hauwai e puta ana i roto i te maitai me ētahi atu koranu ina pāngia e te hauwai whanariki (H2S) me te ahotea. Ka taea e tēnei momo pakarutanga te arahi ki te pakarutanga kino o ngā taputapu, ā, ka puta he mōrearea nui ki te haumaru me te taiao i roto i ngā mahi whakamahine hinu. I whakawhanakehia a NACE MR0175 hei whakaiti i te mōrearea o te SSC mā te whakarato i ngā whakaritenga mō te kōwhiringa me te tohu i ngā rauemi e ātete ana ki te pakarutanga ahotea whanariki.

Ka hipokina e te paerewa te whānuitanga o ngā rauemi, tae atu ki ngā maitai waro me te rino iti-koranu, ngā maitai kore waikura, ngā koranu nikara, me ētahi atu koranu ātete-waikura. Ka whakaratohia he aratohu mō te kōwhiringa rauemi, te maimoatanga wera, ngā rohe pakeke, me ngā whakaritenga whakamātautau hei whakarite kia ātete ngā rauemi e whakamahia ana i roto i ngā mahi whakamahine hinu ki te pakaru ahotea whanariki.

Ko tētahi o ngā āhuatanga matua o te NACE MR0175 ko te tohu i ngā rauemi mā te whakamātautau me te tuhi tuhinga. E whakamārama ana te paerewa i ngā whakaritenga whakamātautau motuhake, pērā i te whakamātautau pakeke, te whakamātautau kume, me te whakamātautau pakaru ahotea whanariki, hei whakaatu i te ātete o ngā rauemi ki te pakaru ahotea whanariki. Hei tāpiri, e hiahiatia ana e te paerewa kia whakaratohia e ngā kaihanga he tuhinga, pērā i ngā pūrongo whakamātautau rauemi me ngā tiwhikete tutuki, hei manatoko kei te tutuki ngā rauemi i ngā whakaritenga o te NACE MR0175.

Kei roto hoki i te NACE MR0175 ngā aratohu mō te hoahoa me te hanga i ngā taputapu me ngā wāhanga hei whakaiti i te mōrearea o te pakaru o te ahotea whanariki. Kei roto i tēnei ko ngā taunakitanga mō ngā tikanga whakarewa, ngā maimoatanga mata, me ētahi atu mahi hei ārai i te pakaru i puta mai i te hauwai i te mara.

He mea nui te tutuki i ngā whakaritenga o te NACE MR0175 hei whakarite i te pono me te pono o ngā taputapu me ngā wāhanga i roto i ngā mahi whakamahine hinu. Mā te whiriwhiri me te whakarite i ngā rauemi kia rite ki te paerewa, ka taea e ngā kaiwhakahaere te whakaiti i te mōrearea o te pakaru o te ahotea whanariki me te whakarite i te haumaru me te whai huatanga o ā rātou whare.

Hei whakamutunga, he paerewa nui te NACE MR0175 mō te umanga hinu me te hau, e whakarato ana i ngā aratohu mō te whiriwhiri me te tohu i ngā rauemi e ātete ana ki te pakaru o te ahotea whanariki i roto i ngā taiao whakamahine hinu waikura. Mā te whai i ngā whakaritenga o tēnei paerewa, ka taea e ngā kaiwhakahaere te whakaiti i te mōrearea o te pakaru o te ahotea whanariki me te whakarite i te pono me te pono o ā rātou taputapu me ngā wāhanga. He mea nui te tutuki i te NACE MR0175 hei pupuri i te haumaru me te whai huatanga o ngā mahi whakamahine hinu.
