Hāʻawi nā ʻōnaehana hoʻonohonoho like ʻole i nā ʻano like ʻole o ka noi, a ʻaʻole like ka nānā ʻana o ka paipu kaumaha.
I kēia lā e kūkākūkā mākou i ka ʻōnaehana maʻamau EN o EN10220.
Ka nānā ʻana o ka maʻamau EN 10220
EN 10220ʻO ia ka maʻamau ʻEulopa no nā ana a me ka hoʻomanawanui ʻana o nā paipu kila ʻole a welded.
ʻO ka maʻamau EN 10220 he ākea ākea o nā noi a hoʻohana nui ʻia i ka ʻoihana ʻaila, kinoea, kemika, kūkulu, a me nā ʻoihana mālama wai.
Aia ka maʻamau i ke anawaena o waho (OD) a me ka mānoanoa o ka paia (WT) o nā paipu kila, e hāʻawi ana i kahi papa kuhikuhi o nā alakaʻi a me nā kikoʻī like ʻole no ka hoʻolālā ʻenehana a me ka hana ʻana e hōʻoia i ka kūlike a me ka hoʻololi ʻana o nā huahana paipu i hana ʻia e nā mea hana like ʻole.
Ke Kauna Helu Kaumaha
Hāʻawi ʻia ke ʻano o ka helu ʻana i ka nuipa ma ka mika no ka lōʻihi o ka lōʻihi ma EN 10220.
M=(DT)×Tx0.0246615
Mʻo ka nuipaʻa o kēlā me kēia ʻāpana lōʻihi i kg/m,
Dʻo ke anawaena waho i ʻōlelo ʻia ma mm,
Tʻo ia ka mānoanoa pā i ʻōlelo ʻia ma mm.
Hoʻokumu ʻia kēia helu ma kahi kiko o 7.85 kg/dm3.(kg/dm3ʻo ia ka ʻāpana o ka mānoanoa, cubic decimeters.)
Hiki ke hoʻohana ʻia nā waiwai i helu ʻia i nā paipu me nā ʻano waiwai like ʻole, akā pono e hoʻonui ʻia me kahi kumu o
1.015 no ka austenitic stainless steel （Hoʻokumu ʻia kēia helu ma kahi mānoanoa o 7.97 kg/dm3）.
0.985 no ka ferritic a me ka martensitic stainless steel （Hoʻokumu ʻia kēia helu ma kahi kiko o 7.73 kg/dm3）.
Hiki ke helu ʻia ma muli o nā kumu kūʻai like ʻole no kēlā me kēia hui o nā māka kila kila i hāʻawi ʻia ma EN 10088-1.
EN 10220 Pūʻulu Hoʻohālikelike
EN 10220e like me ke kiʻekiʻe o ka standardization o nā paipu a me kā lākou mau mea pono.ʻEkolu moʻo.
moʻo 1: nā anawaena o waho e hoʻohālikelike ʻia nā mea pono a pau no ke kūkulu ʻana i nā ʻōnaehana paipu;
moʻo 2: nā anawaena o waho no ka mea ʻaʻole i hoʻohālikelike ʻia nā mea pono a pau;
moʻo 3: nā anawaena o waho i loaʻa ai nā mea hana maʻamau.
Nā palapala paona paipu no EN 10220 Series 1
ʻO ka paipu OD o kēia pūʻulu e hahai pololei ana i nā kūlana honua a ʻoihana paha, a hāʻawi ka mākeke i nā pono kūpono piha e like me nā flanges, couplings, a me nā kuʻekuʻe.
Hoʻomaʻamaʻa kēia hoʻohālikelike piha i ka hoʻolālā a me ke kaʻina hana a hoʻemi i ka pono o nā ʻāpana maʻamau a me nā kumukūʻai maʻamau.
Nā palapala paona paipu no EN 10220 Series 2
Hoʻohālikelike ʻia ka ʻāpana OD o kēia ʻano paipu, akā ʻaʻole i hoʻohālikelike ʻia nā pono āpau.Hiki ke loaʻa kekahi mau mea maʻamau, e like me nā flanges a i ʻole nā kuʻekuʻe, aʻo nā ʻāpana ʻē aʻe paha e pono ke hoʻoponopono ʻia, e hoʻohui i ke kumukūʻai a me ka paʻakikī o ka papahana.
Nā palapala paona paipu no EN 10220 Series 3
ʻO kēia ka hihia me ka nui o nā paipu kikoʻī a i ʻole ka nui o ka nui o ka nui o nā mea hoʻopili a me nā ʻāpana, hoʻonui i ke kumukūʻai o ka hoʻolālā ʻana a me ka hoʻokō ʻana i ka papahana, a me ka hoʻolōʻihi ʻana i ke kaʻina kūʻai a me ka hana.
Nā Papa Kaumaha Paipu no nā Mānoanoa Pā 70 -100 mm
No nā paipu mānoanoa me ka mānoanoa o ka pā mai 70 mm a 100 mm, ua kuhikuhi ʻia nā koi ma EN 10220, Papa 2.
ʻAʻole hiki ke loaʻa nā mea pono no nā paipu pā kaumaha me nā ana e like me ka Papa 2 me ka nānā ʻole i ka moʻo ma ka Papa 1 kahi i hoʻokaʻawale ʻia ai ke anawaena kūpono o waho.
ʻO mākou kahi mea hana kiʻekiʻe kiʻekiʻe welded carbon steel paipu a me ka mea hoʻolako mai Kina, a me kahi mea hoʻoheheʻe paipu kila maʻemaʻe, hāʻawi iā ʻoe i kahi ākea o nā paipu kila!
