I waena o lākou,Paipu ASTM A252, ma ke ʻano he mea nui o ka ʻenekinia hoʻokumu pila, ua 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 o ka Paipu ASTM A252a meNā Nui Paipu ASTM A252, a hōʻike i ka hana koʻikoʻi o nā paipu wili arc submerged A252 grade 3 o kā mākou hui i nā hana e like me nā paipu wai ʻino.
He aha ka paipu ASTM A252?
Uhi ke kūlana ASTM A252 i nā paipu kila i hoʻopaʻa ʻia a me nā paipu kila seamless i hoʻohana ʻia i ka ʻenekinia hoʻokumu pila, kahi i hoʻohana nui ʻia ma nā Alahaka, nā kahua o nā hale kiʻekiʻe a me nā hale ʻē aʻe e pono ai ka ikaika kiʻekiʻe a me ke kākoʻo hilinaʻi. Ua māhele ʻia kēia kūlana i ʻekolu mau papa, kahi e hana maikaʻi ai nā paipu Papa 3 ma ke ʻano o ka ikaika a me ke kūpaʻa, a kūpono loa no nā hiʻohiʻona noi hana kaumaha a me nā ukana kiʻekiʻe.
Ka Nānā ʻana i nā Ana a me nā Kikoʻī o ka Paipu ASTM A252
No nā ʻenekinia a me nā mea hoʻoholo papahana, ʻo ka hopu pono ʻana i nā Ana Paipu ASTM A252 ke kī i ke koho hoʻolālā.

Eia kekahi laʻana, ʻo nā kikoʻī paipu maʻamau he anawaena o 12 ʻīniha a me ka mānoanoa o ka paia he 0.375 ʻīniha. Kākoʻo mākou i ka hana i hana ʻia e hōʻoia i loaʻa i kēlā me kēia paipu nā waiwai mechanical a me ke kūpaʻa e pono ai no ka papahana, e hoʻokō ana i nā koi āpau mai ka ʻenekinia kūlanakauhale a hiki i nā ʻoihana ʻoihana nui.
Ikaika ʻoihana: Hana ʻia ma Cangzhou, hoʻoili ʻia ka maikaʻi
Aia kā mākou hui ma ke kūlanakauhale ʻo Cangzhou, ma ka moku ʻo Hebei. Mai kona hoʻokumu ʻia ʻana i ka makahiki 1993, ua hoʻolaʻa ʻia ia no ka hana ʻana i nā paipu kila a me ka hana hou ʻana i ka ʻenehana. Uhi ka hui i kahi ʻāpana o 350,000 mika kuea, he 680 miliona yuan ka huina waiwai a hoʻolimalima i kahi kokoke i 700 mau kānaka. Ua hoʻolauna mākou i nā lako hana hana a me nā lako hoʻāʻo holomua o ka honua e hōʻoia i kēlā me kēiaPaipu ASTM A252ʻo ka haʻalele ʻana i ka hale hana e kūlike a ʻoi aku paha ma mua o nā kūlana o ka ʻoihana.
Paipu Welded Spiral Submerged arc Papa 3 A252: Ke koho kūpono no nā ʻōnaehana paipu wai ʻino
ʻO ka huahana hae o kā mākou hui, ʻo ka paipu wili i hoʻopaʻa ʻia me ke arc spiral A252 grade 3, ua hana ʻia me ka hoʻohana ʻana i ke kaʻina hana wili i hoʻopaʻa ʻia me ke arc spiral (SAWH). He like a paʻa ke kaula wili, me ka ikaika kūkulu holoʻokoʻa kiʻekiʻe a me ke kūpaʻa maikaʻi loa i ka compression a me ke kūlou ʻana.
Hana ʻia kēia huahana me ke kila kiʻekiʻe a he kūpaʻa maikaʻi loa ia i ka pala a me ke komo ʻana, e kūpono loa ia no nā ʻano ʻino e like me ka mālama ʻana i ka wai ʻino a me ka hoʻokele ʻana i nā pou kumu. Hoʻokō mākou i kahi ʻōnaehana hoʻomalu maikaʻi ma ke kaʻina holoʻokoʻa. Mai nā mea maka e komo ana i ka hale hana a hiki i nā huahana i pau e haʻalele ana i ka hale hana, hahai pono kēlā me kēia kaʻina hana i ke kūlana ASTM A252 e hōʻoia i ka pololei o nā ana paipu a me ka hana hilinaʻi.
