He aha ka NACE MR0175?

ʻO NACE MR0175, i ʻike ʻia hoʻi ʻo "Standard Material Requirements for Resistance to Sulfide Stress Cracking in Corrosive Petroleum Refining Environments," he kūlana i hoʻomohala ʻia e ka National Association of Corrosion Engineers (NACE) e hoʻoponopono i ka pilikia o ka sulfide stress cracking i ka ʻoihana aila a me ke kinoea. Hāʻawi kēia kūlana i nā alakaʻi no ke koho ʻana a me ka hōʻoia ʻana o nā mea i hoʻohana ʻia i nā lako a me nā ʻāpana e hōʻike ʻia i nā wahi corrosive i nā hana hoʻomaʻemaʻe petroleum.

ʻO ka haki ʻana o ka sulfide stress (SSC) kahi ʻano o ka haki ʻana i hoʻokomo ʻia e ka hydrogen e hana ʻia i loko o ke kila a me nā mea hao ʻē aʻe ke hōʻike ʻia lākou i ka hydrogen sulfide (H2S) a me ke kaumaha. Hiki i kēia ʻano haki ke alakaʻi i ka hāʻule ʻana o nā lako a hoʻopilikia i ka palekana koʻikoʻi a me nā pilikia kaiapuni i nā hana hoʻomaʻemaʻe petroleum. Ua hoʻomohala ʻia ʻo NACE MR0175 e hōʻemi i ka pilikia o SSC ma ka hāʻawi ʻana i nā koi no ke koho ʻana a me ka hōʻoia ʻana o nā mea i kū i ka haki ʻana o ka sulfide stress.

Uhi ke kūlana i nā ʻano mea like ʻole, me ke kalapona a me nā kila haʻahaʻa-alloy, nā kila kila kila, nā nickel alloys, a me nā mea hao ʻē aʻe e kū i ka pala. Hāʻawi ia i nā alakaʻi no ke koho ʻana i nā mea, ka mālama wela, nā palena paʻakikī, a me nā koi hoʻāʻo e hōʻoia i ka pale ʻana o nā mea i hoʻohana ʻia i nā hana hoʻomaʻemaʻe petroleum i ka haki ʻana o ka sulfide stress.

ʻO kekahi o nā mea nui o NACE MR0175 ka hōʻoia ʻana o nā mea ma o ka hoʻāʻo ʻana a me ka palapala. Hōʻike ka maʻamau i nā koi hoʻāʻo kikoʻī, e like me ka hoʻāʻo paʻakikī, ka hoʻāʻo tensile, a me ka hoʻāʻo ʻana i ka haki ʻana o ka sulfide, e hōʻike i ke kūpaʻa o nā mea i ka haki ʻana o ka sulfide. Eia kekahi, koi ke maʻamau i nā mea hana e hāʻawi i nā palapala, e like me nā hōʻike hoʻāʻo mea a me nā palapala hōʻoia, e hōʻoia i ka hoʻokō ʻana o nā mea i nā koi o NACE MR0175.

Hāʻawi pū ʻo NACE MR0175 i nā alakaʻi no ka hoʻolālā a me ka hana ʻana o nā lako a me nā ʻāpana e hōʻemi i ka pilikia o ka haki ʻana o ka sulfide stress. Hoʻokomo pū kēia i nā ʻōlelo paipai no nā kaʻina hana kuʻihao, nā mālama ʻana i ka ʻili, a me nā hana ʻē aʻe e pale aku ai i ka haki ʻana o ka hydrogen ma ke kahua.

He mea nui ka mālama ʻana me NACE MR0175 no ka hōʻoia ʻana i ka pono a me ka hilinaʻi o nā lako a me nā ʻāpana i nā hana hoʻomaʻemaʻe ʻaila. Ma ke koho ʻana a me ka hoʻomaʻamaʻa ʻana i nā mea e like me ke kūlana, hiki i nā mea hana ke hōʻemi i ka pilikia o ka haki ʻana o ka sulfide stress a hōʻoia i ka palekana a me ka pono o kā lākou mau hale.

I ka hopena, ʻo NACE MR0175 kahi kūlana koʻikoʻi no ka ʻoihana aila a me ke kinoea, e hāʻawi ana i nā alakaʻi no ke koho ʻana a me ka hōʻoia ʻana o nā mea i kū i ka haki ʻana o ka sulfide stress i nā wahi hoʻomaʻemaʻe petroleum corrosive. Ma ka hahai ʻana i nā koi o kēia kūlana, hiki i nā mea hana ke hōʻemi i ka pilikia o ka haki ʻana o ka sulfide stress a hōʻoia i ka pono a me ka hilinaʻi o kā lākou lako a me nā ʻāpana. He mea nui ka hoʻokō ʻana me NACE MR0175 no ka mālama ʻana i ka palekana a me ka pono o nā hana hoʻomaʻemaʻe petroleum.

Hiki iā Hikelok ke hāʻawi i nā huahana like ʻole e kūlike me ke kūlana NACE MR0175, e like meNā Mea Hoʻohui Paipu, Nā Paipu Hoʻohui, Nā kiwikā poepoe, Nā Kiwikā Nila, Nā Valve Nānā, Nā Valve Hoʻomaha, Nā Pauna Laʻana.
