I ka ulu mau ʻana o ke kūkulu ʻana a me nā noi ʻoihana, ʻoi aku ka nui o ka noi no nā mea kiʻekiʻe. Ma waena o kēia mau mea, ua lilo nā ʻāpana hollow i mea hoʻonā no nā ʻano noi like ʻole, ʻoi aku hoʻi i ka hana o ke kūkulu ʻana, petrochemical a me nā ʻōnaehana boiler kiʻekiʻe.
Aia ma ke alo o ka ʻoihana kahi mea hana alakaʻi i hoʻokumu ʻia ma Cangzhou, Hebei Province. Hoʻokumu ʻia i ka makahiki 1993, ua ulu wikiwiki ka ʻoihana i nā makahiki, e uhi ana i kahi ʻāpana o 350,000 square square a me nā waiwai āpau o 680 miliona yuan. Me nā limahana hoʻolaʻa 680 a me nā mea hana maikaʻi loa, hiki i ka hui ke hoʻokō i nā pono like ʻole o nā mea kūʻai.
ʻO kekahi o nā huahana kūʻokoʻa i hāʻawi ʻia e kēia mea hana, ʻo ia ka laulā o nā paipu alloy, loaʻa i nā nui mai 2 iniha a 24 iniha. Hana ʻia mai nā mea kiʻekiʻe e like me P9 a me P11, kūpono kēia mau paipu no ka hoʻohana ʻana i nā wahi wela kiʻekiʻe. ʻO kā lākou mau noi nui e pili ana i nā wahi hoʻomehana i nā paila wela kiʻekiʻe, economizers, headers, superheaters, a me reheater. Eia kekahi, ʻo kēia mau paipu alloy he mea nui ia i ka ʻoihana petrochemical, kahi mea nui ka lōʻihi a me ke kū ʻana i nā kūlana koʻikoʻi.
Hana ka huinā paipu hollow-sectionka mea e hāʻawi i ka ikaika a me ka paʻa no kahi ākea o nā noi. ʻO ko lākou ʻano kūʻokoʻa e ʻae ai i ka hoʻoili ʻana i ka ukana kūpono, ʻoi aku ka maikaʻi no ke kūkulu ʻana i nā papahana kahi e koʻikoʻi ai ke kūpaʻa o ka hale. Inā hoʻohana ʻia i ke kūkulu hale a i ʻole he ʻāpana o nā ʻōnaehana ʻoihana paʻakikī, hāʻawi kēia mau paipu i ka hilinaʻi a me ka hana e hiki ai i nā ʻenekinia a me nā mea kākau ke hilinaʻi.
ʻO kekahi o nā pōmaikaʻi nui o nā paipu hollow section ʻo ko lākou hiki ke kū i ke kaomi kiʻekiʻe a me nā mahana. ʻO kēia ka mea kūpono iā lākou no nā ʻoihana e koi ana i nā mea hiki ke kū i nā kūlana paʻakikī. I ka ʻoihana petrochemical, no ka laʻana, ua hoʻokau pinepine ʻia kēia mau paipu i nā mea corrosive a me nā wela wela. Hoʻolālā ʻia nā paipu alloy i hāʻawi ʻia e kēia mea hana e kū i kēlā mau pilikia, e hōʻoia i ka lōʻihi o ka lawelawe ʻana a me ka hana palekana.
Eia kekahi, ʻaʻole i kaupalena ʻia ka versatility o nā paipu hollow section i nā noi ʻoihana. Hoʻohana nui ʻia lākou i ka hoʻolālā hale, kahi e hiki ai i kā lākou hoʻopiʻi aesthetic a me nā pono hoʻolālā ke hoʻonui i ke ʻano holoʻokoʻa o kahi papahana. Mai nā skyscrapers hou a hiki i nā alahaka hou, ua lilo kēia mau paipu i mea pono no ka hoʻolālā o kēia wā.
ʻO nā mea āpau, ʻo ka ʻāpana hollow structural tubes i hana ʻia e kēia mea hana ʻo Cangzhou e hōʻike ana i kahi hui o ka maikaʻi, ka lōʻihi, a me ka versatility. Me kahi waihona o nā paipu alloy mai ka 2 iniha a 24 iniha, a me nā māka e like me P9 a me P11, hiki i ka hui ke lawelawe i nā ʻoihana like ʻole e like me nā ʻōnaehana boiler kiʻekiʻe a me nā petrochemical. Ke hoʻomau nei ka noi no nā mea hilinaʻi a me nā mea hana kiʻekiʻe, ua mākaukau kēia mea hana e hoʻokō i nā pilikia o ka honua hou a hōʻoia i ka loaʻa ʻana o kāna mau mea kūʻai aku i nā huahana maikaʻi loa. Inā hoʻohana ʻia ia i ke kūkulu ʻana, nā noi ʻoihana a i ʻole nā hoʻolālā hale hou, ʻo nā ʻāpana hollow structural tubes he mea nui ia o ka hoʻolālā ʻana i ka wā e hiki mai ana.
