ʻOiai aia nā mea like i kekahi mau ʻano, loaʻa iā lākou ko lākou ʻano ponoʻī a me nā noi.
A laila e nānā mākou i nā ʻokoʻa nui ma waena o ASTM A500 a me ASTM A501 a pehea e hoʻohana ʻia ai i nā noi like ʻole.
Nā Kaʻina Hana Hana
Nā Kaʻina Hana Hana ASTM A500
E hana ʻia ka paipu ASTM A50 e nā kaʻina hana ʻole a welded.
E hana ʻia nā paipu welded mai ke kila ʻōwili palahalaha e ke kaʻina uila-kūʻē-weld (ERW).
Nā Kaʻina Hana Hana ASTM A501
E hana ʻia nā paipu e kekahi o kēia mau kaʻina hana: seamless, wili puʻupuʻu umu (hoʻomau mau);kuʻikuʻi kūʻē a i ʻole ka wiliwili arc submerged.
A laila e hoʻomaʻamaʻa hou ʻia ma luna o ka ʻāpana keʻa holoʻokoʻa a hoʻoheheʻe ʻia e ka hoʻohaʻahaʻa a i ʻole ka hana ʻana, a i ʻole nā mea ʻelua.
E hana ʻia ka hana ʻano hope ma ke kaʻina hana wela.
Nā Kaʻina Hana Hana ʻokoʻa
ʻAe nā kūlana ʻelua i ka hoʻohana ʻana i nā ʻenehana hana paipu seamless;
Inā hoʻohana ʻia kahi kaʻina hana kuʻi ʻana no ka hana ʻana, hoʻohana ʻo ASTM A500 i ka uila-resistance-welded (ERW), ʻoiai ʻo ASTM A501 e ʻae i nā ʻano hana kuʻihao like ʻole, me ka uila-resistance-welded (ERW), submerged arc welding (SAW), etc.
Eia nō naʻe, koi ʻo ASTM A501 i ka paipu e mālama i ka wela, e kōkua ana i ka hoʻomaikaʻi ʻana i ka kūlike a me nā waiwai mechanical o ka mea.ʻO ke kumu o ka thermoforming ka hoʻomaikaʻi ʻana i nā waiwai waiwai ma ka mālama ʻana i ka paipu ma mua o ka hoʻopau ʻia ʻana o kona ʻano.
ʻAʻohe o ASTM A500 i nā koi kikoʻī.
Hoʻokaʻawale o nā papa
Kaulana Nui kūpono
Nā ʻāpana Kemika
Hoʻohui pū ʻia, aia kekahi mau ʻokoʻa i ka haku mele ʻana o nā paipu kila kila i kuhikuhi ʻia ma nā kūlana ʻelua, ASTM A500 a me ASTM A501.
Ma ka ASTM A500, ka Papa B a me ka Papa D, ua like ko ka Papa C me ke kalapona e pili ana i ka B a me D. I ka ASTM A501, ua like ka haku mele A me ko ka Papa B. Loaʻa i ka Papa C kahi maʻiʻo kalapona hōʻemi e pili ana i ka Papa B.
I ka ASTM A501, ua like ka haku mele A me ka papa B a me D o A500, akā i ka Papa B a me C ua hoʻemi ʻia ka ʻike kalapona, ua hoʻonui iki ka manganese, a ʻoi aku ka haʻahaʻa o ka phosphorus a me ka sulfur ma mua o ka ASTM A501. ma ka Papa A.
ʻO ka maʻiʻo keleawe he koi haʻahaʻa kūlike ma nā papa āpau.
Hōʻike ʻia nā koi ʻokoʻa kemika i nā pono kikoʻī o nā maʻamau ʻelua no nā kaʻina hana like ʻole a me nā noi, e hōʻoia ana i ka hoʻokō ʻana o ka mea i nā koina hana no kahi ākea o ka ʻenekinia a me nā noi hoʻolālā.

Hāʻawi maʻamau nā mea ma A501 i nā pae kiʻekiʻe o ka ikaika ma muli o ka piʻi ʻana o ka ikaika o ke kila mai ke kaʻina hana wela.
Nā papahana hoʻokolohua
ʻO nā koi like ʻole no nā mea hoʻokolohua ma nā kūlana ʻelua e hōʻike i nā kaʻina hana a me ka hoʻohana ʻana i kēia mau paipu ʻelua.
Pono ka ASTM A500 maʻamau i ka Thermal Analysis, Product Analysis, a me Mechanical Properties i ka hoʻohui ʻana i ka Flattening Test, Flaring Test, a me Wedge Crush Tes no ka hōʻoia ʻana ʻaʻole e hoʻopōʻino ke kaʻina hana anuanu i nā waiwai waiwai.
Hoʻomaopopo ka maʻamau ASTM A501 i ke kaʻina hana thermoforming, a no ka mea ua mālama ʻia nā huahana thermoformed i ka wā o ke kaʻina hana, hiki ke manaʻo ʻia kēia mau hoʻāʻo ʻana no ka mea ua hōʻoia ka mālama wela i ka plasticity a me ka paʻakikī o ka mea.
Nā wahi o Applicatio
ʻOiai ke pāʻani nei nā mea ʻelua i kahi kūlana hoʻolālā, ʻokoʻa ka manaʻo nui.
Hoʻohana nui ʻia ka paipu ASTM A500 i nā hale kūkulu hale, ka hana ʻana i nā mīkini, nā kaʻa kaʻa, a me nā mea mahiʻai ma muli o kāna mau kulou anuanu maikaʻi a me nā waiwai wili.
ʻOi aku ka maikaʻi o ka paipu ASTM A501 no ke kūkulu ʻana a me nā noi hoʻolālā e koi ai i ka ikaika kiʻekiʻe a me ka paʻakikī, e like me ke kūkulu ʻana i ke alahaka a me nā hale kākoʻo nui, ma muli o kona paʻakikī a me ka ikaika.
Hāʻawi nā kūlana ʻelua i ke alakaʻi no ka hana ʻana i nā paipu kila kalapona kiʻekiʻe, akā ʻo ka koho maikaʻi loa e pili ana i nā koi a me nā kaohi o kahi papahana kikoʻī.
Inā pono e hana maikaʻi ka hale i kahi kaiapuni haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o ka ASTM A501 no ka mea, ʻoi aku ka maikaʻi o ka hoʻonui ʻana i ka paʻakikī mai ka hana wela.ʻO ka mea ʻē aʻe, inā e kūkulu ʻia ka hale no kahi kaiapuni i loko, a laila lawa paha ka ASTM A500, no ka mea hiki iā ia ke hāʻawi i ka ikaika i koi ʻia a me ka hiki ke hana, ʻoiai ʻoi aku ka liʻiliʻi.
