ʻO ASTM A671 a me A672 nā kūlana no nā paipu kila i hana ʻia mai nā papa kūlana kiʻekiʻe o ka ipu kaomi e nā ʻenehana fusion uila (EFW) me ka hoʻohui ʻana i nā metala hoʻopihapiha.
ʻOiai ua like lākou ma nā ʻano he nui, e like me nā koi hoʻoheheʻe, ka mālama wela, a me nā ʻae ʻana o ka dimensional, ʻokoʻa lākou i kā lākou laulā o ka noi, ka māka, ka papa, nā ana, a me nā noi kikoʻī.
Ka laulā o ka noi
ASTM A671:Kūlana Kūlana no ka Paipu Kila Uila-Fusion-Welded no ka Lewa a me nā Mahana Haʻahaʻa
ASTM A672: Kikoʻī Kūlana no ka Paipu Kila i Hoʻopili ʻia me ka Fusion Uila no ka Hana Kaomi Kiʻekiʻe ma nā Mahana Kaulike
Hoʻohālikelike Papa
Hoʻokaʻawale ʻia nā ʻōmole e like me ke ʻano o ka mālama wela a lākou e loaʻa ai i ka wā o ke kaʻina hana a inā paha i nānā ʻia a hoʻāʻo ʻia ke kaomi ma ke ʻano radiographic.
ʻOi aku ka laulā o nā mahele o ASTM A671 ma mua o ASTM A672, e hōʻike ana i ke ʻano ʻoi aku ka maʻalahi o A671 i ka hoʻokaʻawale ʻana i nā mea no ka brittleness a me nā ʻano hāʻule e hiki ke hana ma nā wahi haʻahaʻa haʻahaʻa.
ʻO kēia no ka mea hāʻawi ke kūlana A671 i kahi wehewehe kikoʻī o nā waiwai haʻahaʻa haʻahaʻa i hoʻolālā ʻia e hōʻoia i ka hoʻomau ʻana o ka paipu i ka hana maikaʻi i nā kūlana anuanu. I ka hoʻohālikelike ʻana, kālele ʻo ASTM A672 i ka hoʻololi ʻana i nā kaomi like ʻole a me nā kūlana mahana waena, e pili ana i ke alo ʻana a me ka hoʻokele ʻana i nā ʻano pilikia like ʻole.
Hoʻohālikelike Papa
Hoʻokaʻawale ʻia e like me ke ʻano o ka pā i hoʻohana ʻia e hana i nā paipu kila.
Hōʻike nā papa like ʻole i nā ʻano kemika like ʻole a me nā waiwai mechanical no nā kūlana kaomi a me nā mahana like ʻole.
Hiki i nā māka like ʻole ke hoʻopilikia i ke kumukūʻai a me ka hana o kahi papahana.
ʻO ka hoʻohana ʻana i kahi paipu kila kiʻekiʻe aʻe ke ʻano o ke kumukūʻai mea, akā ʻo ke koho kūpono ʻana i nā mea hiki ke hōʻemi i nā kumukūʻai mālama a hoʻolōʻihi i ke ola lawelawe i ka wā lōʻihi.

Nā noi no ka ASTM A671 Steel Tubing
Nā lawelawe CryogenicʻO nā ʻōnaehana hana a me ka halihali e like me ke kinoea kūlohelohe liquefied (LNG), pono nā ʻōmole i hiki ke mālama i nā waiwai mechanical maikaʻi ma nā mahana haʻahaʻa loa.
Nā ʻōnaehana hoʻolako kinoea o ke kūlanakauhaleMa kēia mau ʻōnaehana, pono paha nā paipu e hana i nā mahana haʻahaʻa o ka hoʻoilo, no laila pono nā ʻano paipu kila kikoʻī e hōʻoia i ka palekana a me ka pono.
Nā hale hana kemikaI loko o nā ʻōnaehana hana kemika a me nā ʻōnaehana hoʻoluʻu, lawelawe ʻia kekahi mau wai i nā mahana haʻahaʻa loa, e koi ana i ka hoʻohana ʻana i ka paipu ASTM A671 e pale aku i ka haki ʻana o ka paipu ma muli o ka palupalu i nā mahana haʻahaʻa.
Nā kahua kai a me nā hale ʻeli ʻailaAia pinepine kēia mau hale i nā wai anuanu, a ʻo ka hoʻohana ʻana i ka paipu A671 e hōʻoiaʻiʻo ana i ka hilinaʻi a me ke kūpaʻa i nā wahi kai anuanu.
Nā noi no ka ASTM A672 Steel Tubing
Nā hale hana manaʻOi aku hoʻi i nā ʻōnaehana paila a me ka mahu, pono kēia mau ʻōnaehana i nā paipu e kū i nā mahana kiʻekiʻe a me nā kaomi no ka hoʻoili palekana ʻana o ka mahu a me ka wai wela.
Nā Hale HoʻomaʻemaʻeI ke kaʻina hana hoʻomaʻemaʻe ʻana, pono nā paipu e hoʻoili pono i ka ʻaila maka a me nā huahana ma waena o nā kikowaena hana like ʻole, a pono e hiki i kēia mau paipu ke kū i nā mahana kiʻekiʻe a me ka hoʻouka kemika o ke kaʻina hana.
Nā Laina Hoʻoili Kaomi KiʻekiʻeHoʻohana ʻia nā laina hoʻoili kaomi kiʻekiʻe e halihali i nā wai a i ʻole nā kinoea me ke kaomi kiʻekiʻe e like me ke kinoea kūlohelohe a me ka aila.
