Ma ke kahua o ka hoʻolālā a me ka ʻoihana, ʻo ke koho ʻana i nā mea pono e hoʻoholo pololei i ka lōʻihi a me ka hana pono o ka papahana. Iwaena o lakou,Pipe ASTM A252, ma ke ʻano he kumu kumu o ka ʻenekinia kumu pile, mahalo nui ʻia e ka ʻoihana no kāna hana kākoʻo maikaʻi loa. E hoʻohui kēia ʻatikala i nā huahana o nā ʻoihana hana kiʻekiʻe ma Cangzhou, e kālele ana i ka nānā ʻana Nā Ana Paipu ASTM A252aʻO ka nui o ka paipu ASTM A252, a hōʻike i ka hana koʻikoʻi o kā mākou hui A252 grade 3 spiral submerged arc welded pipes i nā noi e like me nā paipu wai.
He aha ka paipu ASTM A252?
Hoʻopili ʻo ASTM A252 maʻamau i nā paipu kila i hoʻohana ʻia i ka ʻenekinia kumu pile, i hoʻohana nui ʻia ma Bridges, nā kumu o nā hale kiʻekiʻe a me nā hale ʻē aʻe e koi ai i ka ikaika kiʻekiʻe a me ke kākoʻo hilinaʻi. Hoʻokaʻawale ʻia kēia maʻamau i ʻekolu mau māka, a ma waena o nā paipu Papa 3 e hana maikaʻi loa i ka ʻōlelo o ka ikaika a me ka lōʻihi, a kūpono loa i nā hiʻohiʻona noiʻi kaumaha a me nā haʻahaʻa kiʻekiʻe.
ʻIkepili o ka ASTM A252 Pipe Dimensions a me nā kikoʻī
No nā ʻenekinia a me nā mea hoʻoholo hoʻoholo papahana, ʻo ka hopu pololei ʻana i ka ASTM A252 Pipe Dimensions ʻo ia ke kī e koho ai. Hāʻawi kēia ʻano paipu i ka nui o ka paipu ASTM A252. ʻO ke anawaena ka mea maʻamau ma waena o 6 iniha a me 60 iniha, a hiki ke hoʻololi ʻia ka mānoanoa o ka pā e like me nā koi ʻenehana maoli.
No ka laʻana, hiki i nā kikoʻī paipu maʻamau ke anawaena o 12 iniha a me ka mānoanoa pā o 0.375 iniha. Kākoʻo mākou i ka hana maʻamau e hōʻoia i ka loaʻa ʻana o kēlā me kēia paipu i nā waiwai mechanical a me ke kūpaʻa e pono ai no ka papahana, e hoʻokō i nā koi āpau mai ka ʻenekinia municipal a hiki i nā ʻoihana ʻoihana nui.
ʻO ka ikaika o ka ʻoihana: Hana ʻia ma Cangzhou, ua hala ka maikaʻi
Aia kā mākou hui ma Cangzhou City, Hebei Province. Mai kona hoʻokumu ʻana i ka makahiki 1993, ua hoʻolaʻa ʻia i ka hana ʻana i nā paipu kila a me nā ʻenehana ʻenehana. Hoʻopili ka hui i kahi ʻāpana o 350,000 square meters, loaʻa nā waiwai āpau o 680 miliona yuan a hoʻohana ma kahi o 700 poʻe. Ua hoʻolauna mākou i nā mea hana kiʻekiʻe honua a me nā lako hoʻāʻo e hōʻoia i kēlā me kēiaPipe ASTM A252ʻO ka haʻalele ʻana i ka hale hana e hoʻokō a ʻoi aku paha i nā kūlana ʻoihana.
A252 Grade 3 Spiral Submerged arc Welded Pipe: ʻO ke koho kūpono no nā ʻōnaehana pipeline
Hana ʻia ka huahana poʻokela o kā mākou hui, A252 grade 3 spiral submerged arc welded pipe, me ka hoʻohana ʻana i ke kaʻina hana spiral submerged arc welding (SAWH). ʻAʻahu a paʻa ka weld seam, me ka ikaika holoʻokoʻa kiʻekiʻe a me ke kūpaʻa compressive a me ke kūlou maikaʻi.
Hana ʻia kēia huahana me ke kila kila kiʻekiʻe a me nā hiʻohiʻona kūpaʻa maikaʻi loa i ka corrosion a me ke kūpaʻa ʻaʻahu, kūpono loa ia no nā kaiapuni koʻikoʻi e like me ka mālama ʻana i ka wai a me ka hoʻokele puʻu kumu. Hoʻokō mākou i kahi ʻōnaehana hoʻokele maikaʻi ma ke kaʻina holoʻokoʻa. Mai nā mea maka e komo ana i ka hale hana i nā huahana i hoʻopau ʻia e haʻalele ana i ka hale hana, e hahai pono kēlā me kēia kaʻina i ka maʻamau ASTM A252 e hōʻoia i ka nui o ka paipu kūpono a me ka hana pono.
Ka hopena
ʻO ka ASTM A252 Pipe ka mea hiki ʻole ke hoʻololi i ka ʻenehana hou. ʻO kāna mau nui paipu ASTM A252 maʻalahi a me ASTM A252 Pipe Dimensions e hāʻawi i kahi hōʻoia paʻa no nā papahana ʻenekinia like ʻole. Ma ke ʻano he ʻoihana hana koʻikoʻi ma Cangzhou, me 30 mau makahiki o ka hoʻonui ʻana i ka ʻenehana a me ka ʻimi paʻa ʻole i ka maikaʻi, hāʻawi mākou i nā mea kūʻai aku i nā huahana A252 grade 3 spiral submerged arc welded pipe i hilinaʻi nui ʻia a lōʻihi. ʻO ke koho ʻana iā mākou, ʻo ia ke koho ʻana i kahi koho paʻa a hōʻoluʻolu no kāu papahana ʻoihana.
