ʻO ka paipu EFW (Electro Fusion Welded Pipe) he paipu kila i hoʻoheheʻe ʻia i hana ʻia ma ka hoʻoheheʻe ʻana a me ka hoʻoomi ʻana i kahi pā kila e ka ʻenehana wiliwili uila.
ʻAno Paipu
EFW kila paipu mea maʻamau pololei welded seam kila paipu.
Hiki ke paipu kila kalapona a i ʻole paipu kila kila.
Nā Kūlana a me nā Papa EFW

Ke Kaʻina Hana o EFW Steel Pipe
I ka hoʻomaʻamaʻa, ʻoi aku ka paʻakikī o ke kaʻina hana, penei:
Koho waiwai
E koho i ka mea pā kila kūpono e like me ka mea i makemake ʻia a me nā waiwai mechanical.
Pono e nānā ʻia ka pā kila no ka hōʻoia ʻana ʻaʻole ia mai nā hemahema a hoʻomaʻemaʻe ʻia ka ʻili e wehe i nā mea haumia a i ʻole nā oxides e hoʻopilikia i ka maikaʻi o ka weld.
Oki Papa
Hoʻokiʻoki ʻia ka pā i ka nui i makemake ʻia, maʻamau e ka plasma a i ʻole nā ala ʻoki ahi.
Ke ʻoki ʻia, pono paha i nā ʻaoʻao o ka pā i ka mīkini hou aʻe e hōʻoia i ka alignment pololei a me ka pili ʻana i ka wā wili.
Papa hana
Hoʻopili ʻia nā pā kila i loko o nā ʻano cylindrical me ka hoʻohana ʻana i nā paomi a i ʻole nā wili wili.
Hana ʻia nā hoʻololi i ke ʻano o ka paipu i hana ʻia e hōʻoia i ka hoʻonohonoho pono ʻana o nā hopena i ka hoʻomākaukau ʻana no ke kaʻina hana hoʻoheheʻe e pili ana.
Hoʻomākaukau lihi
ʻO ka hopena tubular i hana ʻia he lepo a mīkini ʻia e hana i kahi kihi beveled no ke komo piha ʻana o ka weld.
EFWwiliwili
Me ka hoʻohana ʻana i ka ʻenehana welding arc, ua wela nā kihi o nā pā kila i kahi kūlana hoʻoheheʻe ʻia i nā wela kiʻekiʻe.
Ma ke ʻano o ke arc uila a me ke kaomi, ua hui pū ʻia nā ʻaoʻao o ke kila hoʻoheheʻe ʻia e hana i kahi weld.Pono paha kēia ʻanuʻu i nā welds e hōʻoia i ka ikaika a me ka maikaʻi o ka weld.
Hoʻomaʻamaʻa wela ma hope o ka weld
Ma hope o ka pau ʻana o ka welding, hana ʻia ka mālama ʻana i ka wela ma hope o ka weld e hoʻomaha i nā koʻikoʻi i ka weld a me ke kila.
Hoʻopili maʻamau kēia i ka hoʻomehana ʻana i ka paipu holoʻokoʻa a i ʻole ka wahi weld i kahi mahana kikoʻī a laila hoʻomālili ma lalo o nā kūlana hoʻomalu.
Nānā a ho'āʻo
Nānā maikaʻi ʻia a hoʻāʻo ʻia nā paipu ma hope o ka wili a me ka mālama wela.
Hoʻopili ʻia kēia me ka nānā ʻike maka, ka nānā ʻana i ka dimensional, ka hoʻāʻo ʻino ʻole (e laʻa me ka hoʻāʻo ʻana i ke kani ultrasonic a i ʻole radiographic), a me ka hoʻāʻo ʻana i ka waiwai mechanical (e laʻa me ka hoʻāʻo ʻana i ka tensile a me ka hopena).
Hana hope
ʻOki ʻia nā paipu i nā lōʻihi i ʻōlelo ʻia, chamfered ma nā wēlau, a hoʻopau ʻia paha me ka mālama ʻana i ka ʻili e like me ka uhi ʻana.
Hoʻopaʻa ʻia ka paipu i hoʻopau ʻia me nā ʻike pili e like me ka papa waiwai, ka nui, ka helu umu ahi, a me nā mea ʻē aʻe no ka hiki ke ʻike a hoʻohana.
ʻO nā pono o ka EFW Steel Pipe
ʻO nā wili kiʻekiʻe
ʻO ka hoʻohana ʻana i ka ʻenehana welding electrofusion e hiki ai i nā welds kiʻekiʻe me ka kūlike a me nā haʻahaʻa haʻahaʻa haʻahaʻa, e hoʻonui ai i ka pono o ke kūkulu ʻana.
Nui nui a me ka manoanoa hana pa
He kūpono ke kaʻina hana EFW no ka hana ʻana i nā paipu paʻa nui a me ka manoanoa no ke kaomi kiʻekiʻe a me nā koi kaumaha.
Laulā o nā noi
Hiki ke hoʻopaʻa i kahi ākea o nā kalapona a me nā mea hao hao, kūpono no ka wela kiʻekiʻe, ke kaomi kiʻekiʻe a me nā kaiapuni corrosive.
Hoʻololi i ka hana ʻana
ʻO ka laina hana automated kiʻekiʻe, hiki ke hoʻoponopono ʻia nā ʻāpana kuʻi e like me ka nui o ka hana a me ka mānoanoa.
Hoʻokele waiwai
ʻO ka lōʻihi lōʻihi a me nā koi mālama haʻahaʻa e hāʻawi i ka waiwai holoʻokoʻa maikaʻi ʻoiai ke kumu kūʻai kiʻekiʻe.
Nā hemahema o ka paipu kila EFW
ʻO nā kumukūʻai kiʻekiʻe
ʻOi aku ke kumu kūʻai o ka paipu EFW ma mua o nā ʻano paipu welded ʻē aʻe, e like me ka paipu resistance welded (ERW).ʻO kēia ma muli o nā mea kiʻekiʻe kiʻekiʻe i hoʻohana ʻia a me ke kaʻina hana paʻakikī.
Haʻahaʻa ka hana hana
ʻO ke kaʻina hana EFW he ʻano lohi o ka hana ʻana no ka mea e pili ana i nā kaʻina hana wili a me nā kaʻina hana wela.Hiki i kēia ke alakaʻi i nā pōʻai hana lōʻihi, ʻoi aku ka nui no nā paipu paʻa ʻeleʻele nui.
Ka palena nui
ʻOiai ua kūpono ʻo EFW no ka hana ʻana i ka paipu anawaena nui, ʻaʻole like ka ʻenehana a kūpono paha no nā nui paipu liʻiliʻi, ʻoi aku hoʻi i nā hiʻohiʻona noiʻi kahi e koi ʻia ai ka pololei a me nā anawaena maikaʻi.
Kūleʻa Welina
ʻOiai ke hāʻawi nei ka welding electrofusion i nā welds kiʻekiʻe, hiki i ka hoʻoheheʻe ʻana a me ka hui ʻana i ka wā o ke kaʻina welding hiki ke hoʻokomo i nā hemahema e like me ka porosity, unfusion a me nā inclusions, pono e mālama ʻia ma o ka mana o ka maikaʻi a me ka nānā ʻana.
Nā koi kiʻekiʻe i nā mea hoʻohana
Pono ka hana ʻo EFW i nā mea hoʻokele akamai loa a me nā limahana mālama e hōʻoia i ka hana pono ʻana o ke kaʻina hana wili a holo pono nā mea hana.Ke alakaʻi nei kēia i ka hoʻonui ʻana i ka hoʻopukapuka ʻana i ka hoʻomaʻamaʻa ʻana a me ka hoʻomohala mākaukau no nā limahana.
Nā noi
ʻOihana ʻaila a me ka ʻaila
ʻOihana Kimia
ʻoihana mana
ʻO ke kūkulu ʻana a me ke kūkulu ʻana
ʻO Botop Steel kahi mea hana kiʻekiʻe kiʻekiʻe welded carbon steel paipu a me ka mea hoʻolako mai Kina, a he mea mālama pū kekahi o ka paipu kila maʻemaʻe, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou no kāu pono paipu kila!
