Nā Kūlana ASTM no ka Paipu Kila Kalapona
Ua hoʻomohala ka American Society for Testing and Materials (ASTM) i nā ʻano kūlana like ʻole no nā paipu kila kalapona, e wehewehe pono ana i ka nui, ke ʻano, ka haku mele kemika, nā waiwai mechanical a me nā koi loea ʻē aʻe o nā paipu kila. Eia kekahi mau kūlana ASTM maʻamau no nā paipu kila kalapona:
1. Nā Paipu Kila Kalapona ʻAʻohe Hana
ASTM A53: Pili i ka ʻeleʻele i hoʻopaʻa ʻia a me ka seamless anā paipu kila galvanized wela-ʻūlū, hoʻohana nui ʻia no nā kumu kūkulu, nā ʻōnaehana paipu, a pēlā aku. Ua māhele ʻia kēia kūlana i ʻekolu mau papa: A, B, a me C e like me ka mānoanoa o ka paia.
ASTM A106: Nā paipu kila kalapona humuhumu ʻole i kūpono no ka lawelawe wela kiʻekiʻe, i māhele ʻia i Papa A, B, a me C, i hoʻohana nui ʻia i ka ʻaila, nā paipu hoʻoili kinoea kūlohelohe a me nā ʻoihana kemika.
ASTM A519: Pili i nā kaola kila kalapona humuhumu pololei a me nā paipu no ka mīkini ʻana, me nā koi hoʻomanawanui dimensional koʻikoʻi.
2. Nā Paipu Kila Kalapona i Welded ʻia
ASTM A500: Pili i ka welded anu a me ka huinaha seamless,huinahāa me nā paipu kila ʻano ʻē aʻe, i hoʻohana pinepine ʻia i nā hale.
ASTM A501: Pili i nā paipu kila ʻōwili wela a ʻōwili ʻole ʻia he huinahā, ʻehā huinahā a me nā ʻano ʻē aʻe.
ASTM A513: Pili i ka uilanā paipu kila poepoe i hoʻopaʻa ʻia, i hoʻohana nui ʻia no nā hana mīkini a me nā hana kūkulu.
3. Nā paipu kila kalapona no nā paila a me nā superheaters
ASTM A179: Pili i nā paipu paila kila kalapona haʻahaʻa i huki anu ʻia, kūpono no nā noi mahu kiʻekiʻe.
ASTM A210: Pili i nā paipu paila kila kalapona seamless, i māhele ʻia i ʻehā mau papa: A1, A1P, A2, a me A2P, i hoʻohana nui ʻia no nā paila haʻahaʻa a me ke kaomi haʻahaʻa.
ASTM A335: Pili i nā paipu lawelawe wela kiʻekiʻe kila ferritic seamless, i māhele ʻia i nā papa he nui, e like me P1, P5, a pēlā aku, kūpono no nā paipu wela kiʻekiʻe i nā ʻoihana petrochemical a me ka mana.
4. Nā paipu kila kalapona no nā luawai aila a me ke kinoea
ASTM A252: Pili i ka ʻōwili humuhumu i hoʻopaʻa ʻianā paipu kila i hoʻopaʻa ʻiano nā paila, i hoʻohana pinepine ʻia i ke kūkulu ʻana i kahi kahua ma waho.
ASTM A506: Pili i nā paipu kila kūkulu haʻahaʻa-alloy ikaika kiʻekiʻe, kūpono no ka hana ʻana i nā lako hana ʻaila a me ke kinoea.
ASTM A672: Pili i nā paipu kila silicon manganese kalapona ikaika kiʻekiʻe, kūpono no nā noi e pono ai ka ikaika kiʻekiʻe.
API Spec 5LʻOiai ʻaʻole ia he kūlana ASTM, he kūlana i ʻae ʻia ma ka honua holoʻokoʻa no nā paipu kila no nā paipu aila a me ke kinoea, e uhi ana i nā ʻano paipu kila kalapona he nui.
5. Nā paipu kila kalapona no nā kumu kūikawā
ASTM A312: Pili i nā paipu kila kila ʻole a me nā paipu i hoʻopaʻa ʻia. ʻOiai ʻo ia no ke kila kila, aia pū kekahi mau kikoʻī kila kalapona.
ASTM A795: Pili i ke kila kalapona a me nā bila kila alloy, nā bila poepoe a me kā lākou huahana i hana ʻia e ka hoʻolei mau ʻana a me ka forging, kūpono no nā kahua ʻoihana kikoʻī.
Pehea e koho ai i ke kūlana ASTM kūpono
ʻO ke koho ʻana i ke kūlana ASTM kūpono e pili ana i nā koi noi kikoʻī:
E hoʻohana i ke kaiapuni: E noʻonoʻo i nā mea e like me ka mahana hana, nā kūlana kaomi, a me ke alo o nā mea ʻino.
Nā waiwai mechanical: E hoʻoholo i ka ikaika hua liʻiliʻi e pono ai, ka ikaika tensile a me nā ʻano koʻikoʻi ʻē aʻe.
Pololei o ke ana: No kekahi mau hana mīkini kikoʻī a i ʻole nā hana hōʻuluʻulu, pono paha ke ʻano o ke anawaena waho a me ka mānoanoa o ka paia i kāohi pono ʻia.
Ka mālama ʻana i ka ʻili: Inā pono ka galvanizing wela, ka pena ʻana a i ʻole nā ʻano hana anti-corrosion ʻē aʻe.
