Alloy 825 Coiled Capillary Tubing no na Laina Mana
Hāʻawi ka umbilical hydraulic control pololei i ka mana hydraulic o kēlā me kēia pahu ma luna o kahi kumulāʻau Kalikimaka ma lalo o ka moana, ma o kahi pūʻulu o nā paipu mai ka ʻaoʻao ʻaoʻao o ka hydraulic power unit (HPU) a i ka lāʻau subsea.ʻAʻohe mana uila a hōʻailona paha.ʻO ka hoʻokō ʻana o nā valve ma ka hāʻawi ʻana i ka mana hydraulic i ka paipu kūpono.Hoʻokō ʻia kēia ma ka wehe ʻana i ka valve kūpono ma ka manifold aia ma luna o ka HPU topsided.Hoʻopili ʻia kēia ʻano umbilical i nā ʻōnaehana hana subsea me nā offset pōkole i ka host a me nā lāʻau liʻiliʻi.
Mahalo i ka ʻike a me ka ʻike i loaʻa i ka hana ʻana a me ka nānā ʻana, ua hoʻokō piha nā paipu i hoʻolako ʻia e Meilong i nā koi koʻikoʻi koʻikoʻi o nā ʻoihana ʻaila & kinoea.ʻO ka paipu i kau ʻia i loko o nā umbilicals i hoʻohana ʻia i loko o nā kūlana subsea a me lalo.
ʻO ka maʻiʻo molybdenum i loaʻa i loko o ka 825 coiled tubing kōkua i ke kūpaʻa ʻana o ka alloy i ka lua a me ka crevice corrosion pū kekahi.ʻO ka maʻiʻo chromium i loko o ka Inconel 825 coiled tubing e hāʻawi i ka huila me ke kū'ē i nā ʻano mea hoʻoneʻe like ʻole e like me ka waikawa nitric, nitrates a me ka paʻakai oxidizing.ʻO ka hoʻohui ʻana o ka titanium i loko o 825 coiled tubing me kahi mālama wela kūpono, e hoʻopaʻa i ka metala e kū'ē i ka sensitization i ka intergranular corrosion.
No laila, ʻo nā mea e like me ka Inconel 825 coiled tubing, i hoʻolako ʻia ma lalo o ka ASTM B423 kikoʻī pono e hoʻokō i nā koi kūpono e like me ke kemika a me ka mīkini i kuhikuhi ʻia ma aneʻi.ʻO nā waiwai e like me ka ikaika Tensile, ka ikaika a me ka elongation o ka Inconel 825 coiled tubing ma lalo o ke kūlana i kuhikuhi ʻia a me ka nui o ka Alloy 825 coiled tubing pono e hoʻokō pū me nā pono mechanical pono.Pono e hana ʻia nā hoʻāʻo e like me ka Hydrostatic a me ka uila non-destructive ma ka 825 coiled tubing I ka manaʻo ʻo ka hiki ke kaomi o ka paipu i hana ʻia e ka welded a me ke ʻano annealed e like me ka mea maʻamau i nā code hoʻolālā i lalo-rate. welded tubing ma muli o ka pilikia o ka welded pono ole e alakai ana i nawaliwali.E ho'okumu 'ia ka maika'i o ka weld seam a 'o ka nawaliwali o ka laina waena a 'ike 'ia e ka nana 'ana a/a i 'ole ka ho'ā'o kaomi.No laila, ʻoi aku ka maikaʻi ma mua o nā paipu welded a me nā paipu huki ʻia.
Ma ke kumumanaʻo, ʻo ka hiki ke kaomi o ka paipu i hana ʻia e ke ʻano welded a me ka annealed e like me ka hana maʻamau i nā code hoʻolālā e hoʻohaʻahaʻa i ka paipu welded ma muli o ka pilikia o kahi weld maikaʻi ʻole e alakaʻi i ka nāwaliwali.E ho'okumu 'ia ka maika'i o ka weld seam a 'o ka nawaliwali o ka laina waena a 'ike 'ia e ka nana 'ana a/a i 'ole ka ho'ā'o kaomi.No laila, ʻoi aku ka maikaʻi ma mua o nā paipu welded a me nā paipu huki ʻia.
