Ka hoohana ana oPaipu kila Spirali ka Urban Central Heating

Hoʻokumu ʻia ka hoʻomehana kūloko o ke kūlanakauhale e ka wela nui o ka mahu, ka wai wela e hoʻolako ai i ka ʻoihana paipu kila ma o ke kūlanakauhale a i ʻole nā ​​ʻāpana o ka hoʻomehana i hoʻohana ʻia i ka hana ʻana a me ke ala ola, ʻo ia hoʻi ka wela, nā pūnaewele wela, nā mea hoʻohana wela o ʻekolu ʻāpana.

ʻO ka ʻōnaehana hoʻomehana kūloko o ke kūlanakauhale, ka hoʻokele waiwai a me ka hoʻomohala ʻana i ke kūlanakauhale, ka ʻōnaehana, a me kona pae o ka hoʻomohala ʻana he hōʻailona o ka hoʻonui ʻana i ke kūlanakauhale.ʻO ka hoʻomohala ʻana i ka wahi hoʻomehana kūloko kūloko o ke kūkulu ʻana i ke kūlanakauhale ma Kina, ua lilo ia i kulekele kumu.

ʻO ka cogeneration hoʻomehana waena a hāʻawi nui ʻia i ka maikaʻi o ka hoʻohālikelike ʻana i ka hoʻohālikelike ʻana, ka mea nui i nā wahi aʻe:

1, he waiwai maikaʻi no ke kālā.ʻO nā paila no ka hoʻomehana waena me ka mana nui, hiki ke hiki i ka 90% ka maikaʻi wela kiʻekiʻe, a ʻo ka hoʻopuehu liʻiliʻi liʻiliʻi o ka hoʻomehana wela ma kahi o 60% a i ʻole.No laila, ma kahi o ka hoʻopuehu ʻia ʻana o ka hoʻomehana waena o ke kūlanakauhale e hiki ke mālama i ka 20 a 30% o ka ikehu.

2, maikai kaiapuni pono.ʻO ka pollution kūlanakauhale ka mea nui mai ka hoʻopau ʻana i ka lanahu e hoʻopuka ai i ka carbon dioxide a me ka soot.Hiki ke hoʻemi maikaʻi i ka pollution o ke kūlanakauhale, me ka hoʻohana ʻana i ka kānana kiʻekiʻe, ka nui o ka hoʻoneʻe ʻana o ka lepo o 90 a 98% a i ʻole ke kiʻekiʻe.

3, nā pōmaikaʻi pilikanaka maikaʻi.ʻO ka hoʻomehana kūloko kūloko no ka ʻoluʻolu o ka noho ʻana o ka poʻe, e mālama ana i nā kahua kūkulu kūlanakauhale makamae, e hōʻoluʻolu i ke kūlana hemahema o ka mana ma nā kūlanakauhale nui.

ʻO ka hoʻohana ʻana i ka paipu kila maMoanaa me ka MoanaKūkulu

Ocean engineering kila paipu manao a me ke koho ana, kiko'ī e like me ka hoʻokaʻawale 'ana o ka moana 'enekinia kila hale, a me ka kuhikuhi ana i ka API (American petroleum institute), AISC (American hui no ke kila hale), ASTM (American hui o ka ho'āʻo a me nā mea waiwai. ), ANSI (American national standards institute), ASTM (American society of testing and material), AWS (American welding society), NACE (national association of corrosion engineers) standards and guidelines.Koi no ka moana 'enekinia kila paipu mea, nui ka pono o ke kila pā pono'ī, he haʻahaʻa kalapona kila, kiʻekiʻe ikaika kila, ultra-kiʻekiʻe ikaika kila, kuhiliʻole kila eha waeʻano.E haʻi i ʻelua manaʻo ma ʻaneʻi:

(1) ʻenehana moana o nā lako i lawe ʻia mai he nui loa.I kekahi manawa no ka paipu kila Pelekania a me ka hana ʻana i ke kila kila, ʻoi aku ka maikaʻi o nā koi.Ma ka ʻenekinia moana no ka ʻāpana kūikawā o ka paipu kila, ʻo 100% kāna mau koi āpau no ka weld ultrasonic testing (UT – Ultrasonictesting) a me ka nānā ʻana (MT – Magnetictesting).Aia i loko o ka hale nui o ka paipu kila, ma ka laulā o 300 mm ma nā ʻaoʻao ʻelua o ka seam longitudinal pono 100% UT a me MT.

(2) ʻo ka hana ʻana o ka node paipu no ka mea nui i ka ʻenekinia moana.ʻO nā hale hana node paipu kūikawā ma waho, a ua kūkulu ʻia ka hale.Ka nui o 52000 tons, no ka laʻana, "hoaaloha" o ke kai bohai, e lana ana i ka waihona waihona (FPSO, a hoʻomaʻamaʻa i kekahi o ka ʻumi kaulana kaulana o Kina) o ka lima palupalu kūikawā (YOKE) ka YOKE mooring system a me ke kākoʻo bracket, ka hale kiaʻi kukui, kākoʻo helicopter platform, etc. Aia nā 221 nodes, e hoʻokō i nā koi o AISC, AWS.59 km ka lōʻihi o ka paipu (me ka mamao hoʻomalu hydraulic paipu 28 km, 119 mamao mana valve, pahu pahu 48 alanui).Shipyard i mea e hōʻoia i ka maikaʻi o ke kūkulu ʻana, e koho mai nā kaukani welder he nui o ka welding maikaʻi loa, ʻo ka 15 hope loa i kūpono e like me 6 gr o ka hui papa.I ka ʻenekinia moana i mea e pale aku ai i ka leakage o ka aila a me ke kinoea i loko o ka ʻōnaehana, ʻaʻole i hoʻopaʻa ʻia i ka pilina flange kila paipu, a hoʻohana i ka kuʻekuʻe argon arc.ʻEkolu pūʻulu o TIG welder shipyard a pono hoʻomaʻamaʻa kūikawā.
