I ka pili ʻana i ka paipu kila kila, kū ka paipu ASTM A500 ma ke ʻano he koho maʻamau a hoʻohana nui ʻia i nā ʻoihana like ʻole. Inā ʻoe e pili ana i ke kūkulu ʻana, ka hana ʻana, a i ʻole nā hana ʻenekinia, he mea koʻikoʻi ka hoʻomaopopo ʻana i kā lākou kikoʻī, nā māka, a me nā noi no ka hoʻoholo ʻana i ka ʻike. Ma kēia hōʻuluʻulu nui, e nānā mākou i ka ASTM A500 paipu's nā hiʻohiʻona nui, nā māka like ʻole, a me nā noi he nui.

Ka hoʻomaopopo ʻana i nā kikoʻī Pipe ASTM A500
ʻO ka paipu ASTM A500, ka mea i kapa ʻia ʻo structural steel tubing, i hana ʻia e like me nā kūlana koʻikoʻi i hoʻokumu ʻia e ka American Society for Testing and Materials (ASTM). Kūkākūkā kēia ʻōlelo kikoʻī i nā paipu kalapona kila i hoʻoheheʻe ʻia i hana ʻia i ke anuanu i loaʻa i nā ʻano poepoe, huinaha, a me nā ʻano like ʻole. He kuleana koʻikoʻi ka maʻamau ASTM A500 i ka hōʻoia ʻana e hoʻokō kēia mau paipu i nā koi koʻikoʻi e pili ana i ka hoʻohui ʻana i nā kemika, nā waiwai mechanical, a me nā ʻae ʻana o ka dimensional, e kūpono ana iā lākou no kahi ākea o nā noi hoʻolālā.
ʻO kekahi o nā hiʻohiʻona kūʻokoʻa o ASTM A500 paipu ʻo ia kona ʻano ikaika-a-kaumaha. ʻO kēia hiʻohiʻona ka mea i koho maikaʻi loa no nā noi hoʻolālā kahi i koʻikoʻi ai ka ikaika a me ke kaumaha, e like me ke kūkulu ʻana a me nā hana ʻenekinia. Hana ʻia kēia mau paipu me ka hoʻohana ʻana i ke kaʻina hana kuʻekuʻe uila (ERW), e hōʻoiaʻiʻo ana i kahi wili weld kūpaʻa a hilinaʻi, e hōʻoiaʻiʻo ana i ka pono a me ka lōʻihi o ka paipu.
ʻO ka hui ʻana o ka paipu A500 ka mea nui i ka kalapona a me ka manganese, me ka liʻiliʻi o ka phosphorus a me ka sulfur. Hiki ke ʻokoʻa iki nā lakio kikoʻī o kēia mau mea ma muli o ka maikaʻi i manaʻo ʻia o ka paipu. He mea nui ia e hoʻomaopopo i ka hana ʻia ʻana o nā huahana mai ke kila kalapona, hiki nō iā lākou ke hoʻohui i nā ʻāpana o nā mea hoʻohui. Hiki i kēia mau mea ke hoʻoikaika i nā waiwai kikoʻī, e like me ke kūpaʻa corrosion a i ʻole ka hoʻomaikaʻi ʻana i ka ikaika, e hana ana i nā huahana maʻamau a hoʻohana nui ʻia i nā ʻoihana like ʻole.
Nā Kiʻi kikoʻī a me nā pae o ka paipu ASTM A500
Loaʻa ka paipu ASTM A500 i nā papa he nui, hāʻawi kēlā me kēia mea i nā waiwai mechanical ʻokoʻa e kūpono i nā noi like ʻole. ʻO nā māka maʻamau ka Papa A, Papa B, a me ka Papa C. E nānā pono kākou i kēlā me kēia papa a me kona mau kikoʻī:
Papa A: ʻO kēia ka papa i hoʻohana nui ʻia o ka paipu A500. Hāʻawi ia i kahi kaulike maikaʻi o ka ikaika a me ka ductility, kūpono ia no kahi ākea o nā noi hoʻolālā. He 33,000 psi (228 MPa) ka ikaika ha'aha'a ha'aha'a o nā paipu Papa A a me ka ikaika tensile ha'aha'a o 45,000 psi (310 MPa).
Papa B: Hāʻawi i ka ikaika ʻoi aʻe ma mua o ka Papa A, maikaʻi nā paipu ASTM A500 Grade B no nā noi e koi ana i ka hoʻonui ʻana i ka ukana. He 42,000 psi (290 MPa) kēia mau paipu a me ka ikaika tensile liʻiliʻi o 58,000 psi (400 MPa).
Papa C: ʻO kēia ka māka ikaika kiʻekiʻe loa i loko o ka kikoʻī ASTM A500. Hoʻolālā ʻia nā paipu Papa C no nā noi e koi ana i ka ikaika a me ka rigidity. Ke kaena nei lākou i ka ikaika haʻahaʻa haʻahaʻa o 46,000 psi (317 MPa) a me ka ikaika tensile haʻahaʻa o 62,000 psi (427 MPa).
Ma waho aʻe o kēia mau māka, Nā paipu ASTM A500 loaʻa i nā ʻano like ʻole a me nā nui. ʻO nā paipu poepoe ka mea maʻamau mai ka 0.75 ʻīniha a hiki i ka 24 ʻīniha ke anawaena o waho, aʻo nā paipu huinahā a me nā ʻāpana ʻehā e hāʻawi i kahi ākea o nā ana e kūpono i nā koi o ka papahana.
Nā noi o ASTM A500 Pipe
ʻO ka versatility a me nā waiwai mechanical maikaʻi loa o ka paipu ASTM A500 he koho kaulana ia ma nā ʻoihana a me nā noi. ʻO kekahi o nā mea hoʻohana maʻamau:
Ke kūkulu ʻana a me ke kūkulu ʻana: Hoʻohana nui ʻia nā paipu A500 i ke kūkulu hale, e lawelawe ana ma ke ʻano he kākoʻo, kolamu, a me nā kaola. He kuleana koʻikoʻi lākou i ka hana ʻana i nā ʻōnaehana ikaika a paʻa no nā hale ʻoihana a me nā hale noho. I ka hana ʻana i ke alahaka, hoʻohana pinepine ʻia kēia mau paipu ma ke ʻano he lālā kākoʻo, e hāʻawi ana i ka ikaika e pono ai ke kū i nā ukana kaumaha a me nā koʻikoʻi kaiapuni.
Nā Lako Mahiai: Ke hilinaʻi nei ka ʻoihana mahiʻai i nā paipu A500 no ka hana ʻana i nā mea mahiʻai like ʻole. Mai nā papa tractor a hiki i nā ʻōnaehana irrigation, hāʻawi kēia mau paipu i ka ikaika a me ka lōʻihi e pono ai ke kū i nā kūlana koi o nā hana mahiʻai.
ʻOihana ʻOihana: I ka hana ʻana i nā kaʻa, ʻike kēia mau paipu i nā noi i nā ʻāpana chassis, nā hale ʻōwili, a me nā mea hana ʻē aʻe. ʻO ko lākou kiʻekiʻe ikaika-a-kaumaha ratio kūpono iā lākou no ka hana ʻana i nā papa kaʻa paʻa akā māmā.
Nā Mīkini Hana Hana: Nui nā ʻano mea ʻenehana a me nā mīkini e hoʻokomo i nā paipu A500 i kā lākou hoʻolālā. Hoʻohana ʻia kēia mau paipu i ke kūkulu ʻana i nā ʻōnaehana conveyor, nā lako hoʻokele waiwai, a me nā ʻano like ʻole o nā papa hana a me nā kākoʻo.
Nā Kūlana o waho: Mai nā lako pāʻani a hiki i nā kākoʻo hōʻailona, hoʻohana mau ʻia lākou i nā noi waho. ʻO ko lākou kūpaʻa ʻana i ka corrosion (ke mālama pono ʻia) a me ka hiki ke kū i ke koʻikoʻi o ke kaiapuni e kūpono iā lākou no nā hoʻonohonoho lōʻihi o waho.
ʻĀpana Energy: Ma ka ʻoihana ʻaila a me ka ʻea, hoʻohana ʻia nā paipu A500 no nā noi hoʻolālā like ʻole i nā rig wili, nā kahua o waho, a me nā mea hana. ʻO ko lākou ikaika a me ka hilinaʻi e hoʻolilo iā lākou i mea waiwai i loko o kēia mau wahi koi.
I ko mākou ʻimi ʻana i kā lākou kikoʻī, nā māka, a me nā noi, ʻike maopopo ʻia he kuleana koʻikoʻi kēia paipu kila ma nā ʻoihana he nui. ʻO kona hui pū ʻana o ka ikaika, ka lōʻihi, a me ka hiki ke hoʻololi ʻia he koho maikaʻi loa ia no kahi ākea o nā hana hoʻolālā a me nā mīkini.
Ke koho ʻana i ka huahana no kāu papahana, pono e noʻonoʻo i nā mea e like me ka ikaika i koi ʻia, nā kūlana kaiapuni, a me nā pono noi kikoʻī. Hiki i ke kūkākūkā me nā mea hana akamai a me nā mea hoʻolako ke kōkua iā ʻoe e koho i ka papa kūpono a me nā kikoʻī no kāu mau koi.
E aʻo hou e pili ana i ka hui Longma
No ka hoʻokō ʻana i nā koi like ʻole o kā mākou mea kūʻai aku, ʻo mākou ma Longma Group i hana kūikawā i ka hana ʻana i nā paipu kila kiʻekiʻe, ʻoi aku ka nui o nā paipu ASTM A500. Me kā mākou hana ʻokiʻoki a me ka hoʻokō ʻana i ka maikaʻi, hiki iā mākou ke hāʻawi i nā paipu ASTM A500 hilinaʻi a lōʻihi no kāu mau hana kūkulu. Ua mākaukau kā mākou limahana e kōkua iā ʻoe e ʻimi i ka mea kūpono ASTM A500 paipu ʻO ka hoʻonā, me ka nānā ʻole i kāu ʻoihana-kūkulu, hana, a i ʻole nā mea ʻē aʻe e koi ana i ka pahu kūkulu hale ikaika.
No ka ʻike hou aku e pili ana i kā mākou huahana huahana a i ʻole e kūkākūkā i kāu mau pono papahana, mai hoʻokaʻulua e kelepona mai iā mākou ma info@longma-group.com. Mākaukau mau kā mākou hui o ka poʻe akamai e hāʻawi i ke kākoʻo a me ke kōkua, e hōʻoia ana e loaʻa iā ʻoe ka hopena paipu kila maikaʻi loa no kāu mea e pono ai.
