ASTM A53 Steel Pipe: Hoʻohui a me nā noi
ʻO ASTM A53 Steel Pipe kahi maʻamau i hoʻohana nui ʻia no ka paipu kila ma nā ʻoihana like ʻole. Hoʻopili kēia kikoʻī i ka ʻeleʻele ʻeleʻele ʻeleʻele a hoʻopaʻa ʻia i ka paipu kila galvanized no ka hoʻohana ʻana i nā ʻano noi. ʻIke ʻia ka maʻamau ʻo ASTM A53 no kona versatility a me ka hilinaʻi i nā wahi like ʻole.
Ka haku mele ʻana o asm a53 paipu kila ʻO ke kila kalapona me ka liʻiliʻi o ka manganese, phosphorus, sulfur, a me nā mea ʻē aʻe. Hāʻawi kēia haku mele i ke kaulike o ka ikaika, ductility, a me ka weldability, e kūpono ai no nā ʻano hana like ʻole. Hoʻopili ka maʻamau i nā paipu i nā nui inoa mai NPS 1/8 a i NPS 26, e hāʻawi ana i ka maʻalahi no nā koi o ka papahana.
Loaʻa ka ASTM A53 Steel Pipe i nā noi i nā ʻoihana he nui, me:
- Kaʻaila a me ke kinoea hoʻoili
- ʻO ka wai a me nā ʻōnaehana wai
- Kākoʻo kūkulu hale
- ʻōnaehana pale ahi
- He paipu no ka mahu, ka wai, ka ea, a me ke kinoea
ʻO kekahi o nā pōmaikaʻi nui o ka ASTM A53 Steel Pipe ʻo ia ka hiki ke kū i ke kaomi kiʻekiʻe a me ka mahana, i mea kūpono no ka lawe ʻana i nā wai a me nā kinoea i nā wahi ʻoihana. Hāʻawi ka maʻamau i nā māka like ʻole (A a me B) a me nā ʻano (seamless, uila-kū'ē welded, a me ka umu ahi-welded), hāʻawi i nā koho e hoʻokō i nā koi o ka papahana.
He mea pono ke hoʻomaopopo ʻia hiki ke hoʻolako ʻia ʻo ASTM A53 Steel Pipe me nā hoʻopau hopena like ʻole, me ka hopena maʻamau, wili, a i ʻole me nā hui. Hoʻohui kēia versatility i ka hopena hope i kona hiki ke hoʻololi i nā noi like ʻole.
ASTM A123: Galvanization Standard no nā huahana kila i hana ʻia
ʻOiai ʻo ASTM A53 kahi maʻamau no ka paipu kila, ʻo ASTM A123 kahi kikoʻī no nā pale zinc (hot-dip galvanized) ma ka hao a me nā huahana kila. ʻAʻole kikoʻī kēia maʻamau i nā paipu akā pili i kahi ākea o nā huahana kila i hana ʻia, me nā ʻano kila kila, nā papa, nā pā, a me nā mea hou aku.
ʻO ke kumu nui o ka ASTM A123 ka hāʻawi ʻana i nā alakaʻi no ke kaʻina hana galvanization, e pili ana i ka uhi ʻana i ke kila a i ʻole ka hao me kahi papa o ka zinc e pale aku i ka corrosion. Hoʻonui nui kēia kaʻina hana i ka lōʻihi a me ka lōʻihi o nā huahana kila, ʻoi aku ka poʻe i ʻike ʻia i nā kūlana kūlohelohe koʻikoʻi.
ʻO nā mea nui o ka ASTM A123 ka:
- E wehewehe ana i nā koi mānoanoa liʻiliʻi e pili ana i nā ʻano mea
- Ka wehewehe ʻana i ke kaʻina hana galvanization a me nā ana hoʻomalu maikaʻi
- Hāʻawi i nā alakaʻi no ka hoʻopili ʻana a me ka hoʻopau ʻana
- Ka wehewehe kikoʻī a me nā kaʻina hana hoʻāʻo no nā huahana galvanized
Nui nā noi o ASTM A123, e uhi ana i nā huahana kila i hoʻohana ʻia ma:
- Kapili alahaka a me ke alaloa
- Nā hale kiaʻi uila
- Nā hale hana ʻoihana
- Kaiapuni moana
- Mea hana lāʻau
He mea nui e hoʻomaopopo i kēlā manawa asm a53 paipu kila hiki ke galvanized, ʻo ke kaʻina hana galvanization ponoʻī e hahai maʻamau i nā alakaʻi i hōʻike ʻia ma ASTM A123. Hōʻike kēia i ke ʻano o ka hana like ʻana o kēia mau maʻamau ʻelua e hana i nā huahana kila kiʻekiʻe.
Ka hoʻohālikelike ʻana i nā mea e pono ai ka uhi: ASTM A53 vs. ASTM A123
I ka pili ʻana i nā koi uhi, aia nā ʻokoʻa nui ma waena o ASTM A53 a me ASTM A123. He mea koʻikoʻi ka hoʻomaopopo ʻana i kēia mau ʻokoʻa no ke koho ʻana i ka huahana kūpono no nā noi kikoʻī a me ka hōʻoia ʻana i ka pale corrosion kūpono.
No ka paipu kila ASTM A53:
- Hāʻawi ka maʻamau i ka ʻeleʻele (ʻaʻole i uhi ʻia) a me ka wela wela.
- I ka wā i galvanized, ua kuhikuhi ʻia ke kaumaha o ka uhi ʻana ma ke ʻano he 1.8 oz/ft² (550 g/m²) o ka uhi zinc.
- Hoʻohana maʻamau ka galvanization i ka ʻili o waho o ka paipu, me ka waiho ʻole ʻia o ka loko i uhi ʻole ʻia a i uhi ʻia paha ma muli o nā koi kikoʻī.
- ʻAʻole hāʻawi ka maʻamau i nā kuhikuhi kikoʻī no ke kaʻina hana galvanization ponoʻī.
ʻO ka ʻokoʻa, ASTM A123:
- Hoʻopili pono ia i ke kaʻina hana galvanization wela a me kāna mau koi.
- Hāʻawi i nā kikoʻī kikoʻī no ka mānoanoa uhi e pili ana i ka mānoanoa o ka mea a me ka waeʻano.
- Pono i ka galvanization o nā ʻili o loko a me waho no nā ʻāpana hollow.
- Hōʻike i nā kaʻina hana hoʻāʻo a me ka nānā ʻana no ka uhi galvanized.
- Hoʻoponopono i nā pilikia e like me ka hoʻopili ʻana i ka uhi ʻana, ka hoʻopau ʻana, a me ka hoʻoponopono ʻana i nā pale galvanized.
ʻOi aku ka paʻa o nā koi o ka uhi ʻana ma ASTM A123 ma mua o nā mea ma ASTM A53. ʻO kēia no ka mea ua hoʻolālā pono ʻia ʻo ASTM A123 e hōʻoia i ka galvanization kiʻekiʻe ma waena o kahi ākea o nā huahana kila, ʻoiai ʻo ASTM A53 ke kālele nui ʻia i nā hiʻohiʻona o ka paipu a me nā ʻano hana, me ka galvanization he hiʻohiʻona koho.
Pono nō hoʻi e ʻike i kēlā manawa asm a53 paipu kilahiki ke galvanized e hoʻokō i nā koi o ASTM A123, ʻaʻole pono nā paipu ASTM A53 āpau i kēia maʻamau. ʻO ka koho pinepine e pili ana i ka noi kikoʻī a me nā kūlana kaiapuni e kū ai ka paipu.
I kekahi mau hihia, ʻoi aku ka nui o nā kaiapuni corrosive koʻikoʻi, pono paha nā hana pale ʻē aʻe ma mua o ke galvanization maʻamau. Hiki i kēia ke komo i ka hoʻohana ʻana i nā pena pale a i ʻole nā uhi i hoʻopili ʻia ma luna o ka ʻili galvanized, a i ʻole ke koho ʻana i nā mea ʻē aʻe.
ʻO Longma Pūʻulu ASTM A53 Pipe kila
I ka hōʻuluʻulu ʻana, ʻoiai asm a53 paipu kila a ʻo ASTM A123 nā kūlana koʻikoʻi i ka ʻoihana kila, lawelawe lākou i nā kumu like ʻole. ʻO ka ASTM A53 kahi maʻamau piha no ka paipu kila, e uhi ana i kāna haku mele, kaʻina hana, a me nā koi hana. ʻO ka ASTM A123, ma ka ʻaoʻao ʻē aʻe, e kālele pono ana i ke kaʻina hana galvanization wela no kahi ākea o nā huahana kila, me ka ʻaʻole i kaupalena ʻia i nā paipu.
He mea koʻikoʻi ka hoʻomaopopo ʻana i kēia mau ʻokoʻa no ke koho ʻana i nā huahana kūpono no nā noi kikoʻī a me ka hōʻoia ʻana i ka pale corrosion kūpono. Inā ʻoe e hana ana i kahi papahana pipeline, kūkulu hale, a i ʻole hoʻomohala ʻana i nā ʻoihana i loko o kahi pōʻino, ʻo ka ʻike ʻana i nā nuances o kēia mau maʻamau e hiki ke kōkua iā ʻoe e hoʻoholo i ka ʻike a hōʻoia i ka lōʻihi a me ka hana o kāu mau mea kila.
Hāʻawi ʻo Longma Group i nā koho hana maʻamau no ka ASTM A53 ERW Pipe e hoʻokō i nā kikoʻī kūikawā a me nā ana o nā papahana pākahi, e hōʻoia ana i ke kūpono a me ka hana. Inā ʻoe e koho ana i kāu hale kūʻai paipu kila astm a53 erw, e hoʻokipa iā LONGMA GROUP ma info@longma-group.com.
