ʻO ASTM A671 a me A672 nā kūlana ʻelua no ka paipu kila i hana ʻia mai nā pā kīʻaha kīʻaha kīʻaha e nā ʻenehana fusion welding （EFW）) me ka hoʻohui ʻana i nā metala filler.
ʻOiai ua like lākou ma nā ʻano he nui, e like me nā koi welding, mālama wela, a me nā ʻae ʻana o ka dimensional, ʻokoʻa lākou i kā lākou kiko o ka noi, ka papa, ka papa, nā ana, a me nā noi kikoʻī.
Lai o ka noi
ASTM A671: Hōʻike maʻamau no ka Pipe kila-Fusion-welded no ka lewa a me nā wela haʻahaʻa.
ASTM A672: Hoʻohālikelike maʻamau no ka Pipe Steel-Fusion-Welded Steel Pipe no ka lawelawe kiʻekiʻe ma nā wela haʻahaʻa.
Hoʻohālikelike Papa
Hoʻokaʻawale ʻia nā paipu e like me ke ʻano o ka mālama wela i loaʻa iā lākou i ka wā o ke kaʻina hana a inā i nānā ʻia a ʻaʻole i nānā ʻia a hoʻāʻo ʻia ke kaomi.
Loaʻa i ka ASTM A671 kahi ākea ākea o nā ʻāpana ma mua o ASTM A672, e hōʻike ana i ke ala ʻoi aʻe o ka A671 i ka hoʻokaʻawale ʻana i nā mea no ka brittleness a me nā ʻano hemahema e hiki ke kū i nā wahi haʻahaʻa haʻahaʻa.
ʻO kēia ke kumu no ka hāʻawi ʻana o ka maʻamau A671 i kahi kikoʻī kikoʻī o nā waiwai haʻahaʻa haʻahaʻa i hoʻolālā ʻia e hōʻoia i ka hoʻomau ʻana o ka paipu i nā kūlana anu.ʻO ka ʻokoʻa, ʻo ka ASTM A672 ka nānā ʻana i ka hoʻololi ʻana i nā ʻano koʻikoʻi like ʻole a me nā kūlana wela haʻahaʻa, e pili ana i ke alo a me ka mālama ʻana i nā ʻano koʻikoʻi like ʻole.
Hoʻohālikelike Papa
Hoʻokaʻawale ʻia e like me ke ʻano o ka pā i hoʻohana ʻia no ka hana ʻana i nā paipu kila.
Hōʻike nā māka ʻokoʻa i nā haku mele like ʻole a me nā waiwai mechanical no nā ʻano paʻi a me nā kūlana wela.
Hiki i nā māka like ʻole ke hoʻopili i ke kumukūʻai a me ka hana o kahi papahana.
ʻO ka hoʻohana ʻana i kahi pae kiʻekiʻe o ka paipu kila ʻoi aku ka nui o nā kumukūʻai waiwai, akā hiki i ke koho ʻana i nā mea pono ke hōʻemi i nā kumukūʻai mālama a hoʻolōʻihi i ke ola lawelawe i ka holo lōʻihi.
Nā noi kikoʻī
Nā noi no ka ASTM A671 Steel Tubing
Nā lawelawe cryogenic: e like me ka liquefied natural gas (LNG) lawelawe a me ka lawe ʻana i nā ʻōnaehana, koi i nā paipu hiki ke mālama i nā waiwai mechanical maikaʻi ma nā wela haʻahaʻa haʻahaʻa.
Pūnaehana hoʻolako kinoea kūlanakauhale: I loko o kēia mau ʻōnaehana, pono e hana nā pipeline i nā mahana hoʻoilo haʻahaʻa, no laila pono nā māka kikoʻī o ka paipu kila e hōʻoia i ka palekana a me ka pono.
Nā hale hana kemika: I loko o nā ʻōnaehana kemika a me nā ʻōnaehana hoʻoluʻu, mālama ʻia kekahi mau wai i nā haʻahaʻa haʻahaʻa loa, e koi ana i ka hoʻohana ʻana i ka paipu ASTM A671 e pale ai i ka haki ʻana o ka paipu ma muli o ka brittleness i nā haʻahaʻa haʻahaʻa.
ʻO nā paepae waho a me nā keʻena wili ʻaila: Loaʻa pinepine kēia mau keʻena i nā wai anuanu, a ʻo ka hoʻohana ʻana i ka paipu A671 e hōʻoia i ka hilinaʻi a me ka paʻa i nā kaiapuni kai anuanu.
Nā noi no ka ASTM A672 Steel Tubing
Mea kanu mana: ʻOi loa i loko o ka paila a me nā ʻōnaehana mahu, pono kēia mau ʻōnaehana i nā paipu i kū i nā wela kiʻekiʻe a me nā kaomi no ka hoʻololi palekana o ka mahu a me ka wai wela.
Nā mea hoʻomaʻemaʻe: Ma ke kaʻina hana hoʻomaʻemaʻe, pono ka paipu no ka hoʻoili pono ʻana i ka aila ʻaila a me nā huahana ma waena o nā keʻena hoʻoili like ʻole, a pono e hiki i kēia mau paipu ke kū i ka wela kiʻekiʻe a me ka hoʻouka kemika o ke kaʻina hana.
Nā Laina Hoʻouna Piʻi Kiʻekiʻe: Hoʻohana ʻia nā laina hoʻoili kiʻekiʻe no ka lawe ʻana i nā wai kaomi kiʻekiʻe a i ʻole nā kinoea e like me ke kinoea maoli a me ka ʻaila.
Nā Pūnaehana Pumi Hana Hana: I ka hana ʻana a me nā noi ʻoihana ʻē aʻe, nui nā ʻōnaehana kaomi e koi i ka paipu kiʻekiʻe kiʻekiʻe hilinaʻi e hōʻoia i ka palekana a me ka hana pono.
Ma ka hoʻokaʻawale ʻana ma waena o kēia mau waiwai a me nā noi, ua ʻike ʻia ʻoiai ʻo ka ASTM A671 a me A672 paipu maʻamau ma luna o kekahi mau ʻenehana, lawelawe lākou i nā kumu like ʻole e pili ana i nā koi kūlohelohe a me ka hana.
