He aha kaʻu e hoʻolohe ai i ka nānā ʻana i nā pahu mālama wai cryogenic?

Hoʻokaʻawale ʻia ka nānā ʻana i ka pahu wai mālama wai Cryogenic i ka nānā ʻana i waho, ka nānā ʻana i loko a me ka nānā ʻana i nā ʻano he nui.E hoʻoholo ʻia ka nānā ʻana o nā pahu mālama cryogenic e like me nā kūlana ʻenehana o ka hoʻohana ʻana i nā pahu mālama.

 ʻO ka ʻōlelo maʻamau, ʻo ka nānā ʻana o waho ma ka liʻiliʻi hoʻokahi manawa i ka makahiki, ʻo ka nānā ʻana i loko ma ka liʻiliʻi loa i hoʻokahi manawa i kēlā me kēia 3 mau makahiki, a ʻo ka nānā ʻana i nā ʻano he nui ma ka liʻiliʻi i hoʻokahi manawa i kēlā me kēia 6 makahiki.Inā ʻoi aku ke ola o ka pahu mālama haʻahaʻa haʻahaʻa ma mua o 15 mau makahiki, e hana ʻia kahi nānā kūloko a me waho i kēlā me kēia ʻelua makahiki.Inā he 20 mau makahiki ke ola o ka lawelawe, e hoʻokō ʻia kahi nānā kūloko a me waho ma kahi o hoʻokahi manawa i kēlā me kēia makahiki.

1. Nānā kuloko

 1).Inā he ʻaʻahu corrosive ma ka ʻaoʻao o loko a me ka pahu hoʻopaʻa ʻana o ka manhole, a inā he mau māwae i loko o ka welding seam, ka wahi hoʻololi o ke poʻo a i ʻole nā ​​​​wahi ʻē aʻe kahi i kau ʻia ai ke kaumaha;

 2).Ke poino ma ka ʻili o loko a me waho o ka pahu, pono e hana ʻia nā ana mānoanoa o ka pā ma nā ʻāpana i manaʻo ʻia.Inā ʻoi aku ka liʻiliʻi o ka mānoanoa pā liʻiliʻi ma mua o ka mānoanoa liʻiliʻi o ka paia i hoʻolālā ʻia, pono e nānā hou ʻia ka hōʻoia ikaika, a me nā manaʻo no ka hiki ke hoʻohana ʻia a waiho ʻia ke kaomi hana kiʻekiʻe i ʻae ʻia;

 3).Ke loaʻa nā hemahema o ka paia o loko o ka pahu e like me ka decarburization, ka corrosion stress, intergranular corrosion a me nā māwae luhi, e hoʻokō ʻia ka nānā ʻana i ka metallographic a me ke ana paʻakikī o ka ʻili, a e waiho ʻia kahi hōʻike nānā.

2. Nānā waho

 1).E nānā inā paʻa ka papa anti-corrosion, ka papa insulation a me ka papa inoa o nā mea hana o ka pahu waihona, a inā paʻa, paʻakikī a hilinaʻi nā mea palekana a me nā mea hoʻomalu;

 2).Inā he mau māwae, deformation, overheating kūloko, etc. ma ka ʻili o waho;

 3).Ina paha e kahe ana ka wili wili o ka paipu hookui a me na mea kaomi, ina paha e paa ana na bolts, ina paha e poho ana ke kumu, hili a me na ano ano ano e ae.

3, Nānā piha

 1).Hana i ka nānā ʻole i ka pōʻino ma ka weld nui a i ʻole ka pūpū, a ʻo ka lōʻihi o ka nānā ʻana he 20% o ka lōʻihi o ka weld;

 2).Ma hope o ka hala ʻana i ka nānā ʻana i loko a me waho, e hana i ka hoʻāʻo hydraulic ma 1.25 manawa i ke kaomi hoʻolālā o ka pahu waihona a me ka hoʻāʻo ʻana i ka ea ma ke kaomi hoʻolālā o ka pahu waihona.Ma ke kaʻina hana i luna, ʻaʻohe leakage o ka pahu waihona a me nā welds o nā ʻāpana a pau, a ʻaʻohe ʻano deformation maʻamau i ʻike ʻia i ka pahu mālama;

 Ma hope o ka pauʻana o ka nānāʻana i ka pahu mālama haʻahaʻa haʻahaʻa, pono e hanaʻia kahi hōʻike e pili ana i ka nānāʻana i ka pahu mālama, e hōʻike ana i nā pilikia a me nā kumu i hiki ke hoʻohana a hiki ke hoʻohanaʻia akā pono e hoʻoponopono a hikiʻole ke hoʻohana.Pono e mālama ʻia ka hōʻike nānā no ka mālama ʻana a me ka nānā ʻana.
