ʻO ka hoʻomaopopo ʻana i ka paipu ASTM A252: Nui, ʻano maikaʻi, a me nā noi
Astm A252 Paipuhe mea koʻikoʻi i nā noi hoʻolālā ma waena o nā ʻoihana ākea, ʻoi aku hoʻi i nā hana kūkulu hale a me nā ʻoihana. E ʻimi ana kēia blog i ka nui, ka maikaʻi, a me nā noi o ka paipu ASTM A252, e hōʻike ana i nā hiki o kahi mea hana alakaʻi i hoʻokumu ʻia ma Cangzhou, Hebei Province.
He aha ka paipu ASTM A252?
Astm A252 Paipu NuiʻO ia kahi kikoʻī i hoʻomohala ʻia e ka American Society for Testing and Materials (ASTM) e kuhikuhi ana i nā koi no ka paipu kila welded a seamless i hoʻohana ʻia i nā noi piling.

He aha ka paipu ASTM A252?
ʻO ASTM A252 kahi kikoʻī mana i haku ʻia e ka American Society for Testing and Materials (ASTM), kūikawā no nā paipu kila i hoʻohana ʻia i ka hoʻokele pile a me nā noi kākoʻo hohonu. Hoʻopaʻa paʻa kēia maʻamau i ka hoʻohui ʻana i ke kemika, nā waiwai mechanical, ka hoʻomanawanui dimensional a me nā ʻano hoʻāʻo o nā paipu kila, e hōʻoiaʻiʻo ana i ko lākou kūlana maikaʻi loa, ka lōʻihi a me ka hiki ke amo. He koho kūpono ia no nā papahana kumu e like me Bridges, nā hale kiʻekiʻe a me nā awa.
Astm A252 Paipu Ananā ana a me nā kikoʻī
Hoʻokaʻawale ʻia nā paipu ASTM A252 i ʻekolu mau māka e like me nā koi ikaika: GR 1, GR 2, a me GR 3, ma waena o ka papa GR 3 ka ikaika kiʻekiʻe loa. Hiki ke hoʻokō i nā koi ʻenehana like ʻole
ʻO ke anawaena o waho (OD): Mai 6 iniha a 60 iniha, a hiki ke hana ʻia nā ʻano nui.
ʻO ka mānoanoa o ka pā (WT): ʻO ka maʻamau ma waena o 0.188 iniha a me 0.500 iniha, a hiki ke hoʻololi ʻia e like me nā koi o ka compressive a me ke kūlou ʻana.
Length: ʻO ka lōʻihi maʻamau he 20 kapuaʻi a i ʻole 40 kapuaʻi. Kākoʻo ʻia ka hana maʻamau e like me nā koi o ka papahana.
ʻO kēia ākea ākea e hōʻoiaʻiʻo e hiki i nā mea ʻenekinia ke koho i nā kikoʻī kūpono loa no nā papahana kikoʻī.
Hoʻohana ʻia ka paipu ASTM A252 i nā ʻano noi like ʻole, me:
1. Piling: Hoʻohana pinepine ʻia kēia mau paipu e like me nā puʻu lepo i nā hana kūkulu e hāʻawi i ke kūpaʻa a me ke kākoʻo i ka hale.
2. Nā Alahaka: ʻO ka ikaika a me ka lōʻihi o ka paipu ASTM A252 e lilo ia i mea koho maikaʻi loa no ke kūkulu ʻana i ke alahaka, kahi e hiki ai ke pale i nā ukana kaumaha a me nā kūlana kaiapuni.
3. Nā Kūlana Moana: ʻO ka pale ʻana i ka corrosion o kēia mau paipu e hiki ai iā lākou ke hoʻohana ʻia i nā noi kai e like me nā docks a me nā pier.
4. ʻO kaʻaila a me ke kinoea: Ma muli o kāna hana ikaika, hoʻohana pūʻia ka paipu ASTM A252 i kaʻoihanaʻaila a me ke kinoea no ka laweʻana i nā wai a me nā kinoea.
Ma ka hōʻuluʻulu
ʻO ka waiho wale ʻana, he mea koʻikoʻi ka paipu ASTM A252 no kahi ākea o nā noi hoʻolālā, e hāʻawi ana i ka hilinaʻi a me ka ikaika. ʻO kēia hale hana ma Cangzhou, Hebei Province, he mea hana nui o kēia ʻano paipu, e hōʻoiaʻiʻo ana i kāna mau huahana i nā kūlana kiʻekiʻe loa. Me ka hoʻokō ʻana i ka maikaʻi a me ka nānā ʻana i ka hana hou, hoʻomau ka ʻoihana i ka hana koʻikoʻi i nā ʻāpana hana a me nā ʻoihana. Inā ʻoe e pili ana i kahi papahana kūkulu nui a i ʻole e koi i kahi hopena paipu hilinaʻi, he koho maikaʻi loa ka paipu ASTM A252 no kāu mau pono.
