ASTMA53GR.BʻO ka paipu kila seamless kahi mea paipu i hoʻohana nui ʻia i nā ʻōnaehana halihali wai. Loaʻa iā ia nā waiwai mechanical maikaʻi loa a me ke kūpaʻa i ka palaho a hoʻohana nui ʻia i ka aila, kinoea kūlohelohe, wai, mahu a me nā ʻoihana halihali ʻē aʻe.
Pono nā huahana e kūlike me:ASTM A53/A53MNā kikoʻī no nā paipu kila i hoʻopaʻa ʻole ʻia a me ka zinc wela a me nā paipu kila seamless
ʻO ka haku mele kemika o ka paipu kila humuhumu ASTMA53GR.B: ʻO ka haku mele kemika: kalapona ≤0.30, manganese: 0.29~1.06, phosphorus: ≤0.035, sulfur: ≤0.035, silicon: ≥0.10, chromium: ≤0.40, nickel: ≤0.40, keleawe: ≤ 0.40, molybdenum: ≤0.15, vanadium: ≤0.08
Nā waiwai mechanical: ikaika tensile: ≥415MPa, ikaika hua: 240MPa,
Nā kikoʻī huahana: ke anawaena waho 21.3mm ~ 762mm, ka mānoanoa o ka paia 2.0 ~ 140mm
ʻAno hana: ʻōwili wela, kahakiʻi anu, hoʻonui wela, kūlana hoʻouna: ʻōwili wela, mālama wela.
Pono nā huahana e kūlike me nā lula hoʻāʻo ʻano ʻāpana paipu kaomi TSG D7002.
Ka ʻike ʻana a me ka hoʻāʻo ʻanaKūlana ASTMA53Pono ka paipu e hala i kekahi mau hoʻokolohua a me nā hoʻokolohua e like me ka loiloi haku mele kemika, ka loiloi spectral, ka hoʻāʻo ʻana i nā waiwai mechanical, ka hoʻāʻo twisting, ka hoʻāʻo kūlou, ka hoʻāʻo hopena, a me ka ʻike ʻana i nā kīnā radiographic.
Nā ʻano hana o ka paipu kila humuhumu ASTMA53GR.B
1. Nā waiwai mechanical maikaʻi loa
He ikaika a paʻakikī hoʻi ka paipu kila ASTMA53GR.B a hiki ke kū i ke kaomi nui a me ke kaumaha, e hōʻoiaʻiʻo ana i ka palekana a me ke kūpaʻa o ka ʻōnaehana pipeline. Eia kekahi, he kūpaʻa maikaʻi hoʻi ka mea i ka ʻaʻahu a me ke kūpaʻa i ka hopena, hiki ke hoʻolōʻihi i ke ola lawelawe o ka pipeline.
2. Ke kūpaʻa ikaika i ka palaho
Hana ʻia ka paipu kila humuhumu ASTMA53GR.B me ke kila hoʻonohonoho kalapona kiʻekiʻe. Ma hope o ke kaʻina hana wela koʻikoʻi, loaʻa iā ia ke kūpaʻa maikaʻi i ka pala a hiki ke pale aku i ka ʻino ʻana o nā kemika e like me nā waikawa a me nā alkalis, e hōʻoiaʻiʻo ana i ka hana paʻa lōʻihi o ka ʻōnaehana paipu.
3. Hana hana maikaʻi
He maikaʻi ka weldability, ka ʻoki a me ka plasticity o ka paipu kila ASTMA53GR.B, e maʻalahi ai ke hana a hoʻokomo. Eia kekahi, he maikaʻi ke kūpaʻa o ka mea i ke kiʻekiʻe a me ka haʻahaʻa o ka mahana a hiki ke mālama i ka hana paʻa i nā ʻano ʻino.
Nā kahua noi o ka paipu kila ASTMA53GR.B
Hoʻohana nui ʻia ka paipu kila humuhumu ASTMA53GR.B ma nā kahua halihali o ka ʻaila, ke kinoea kūlohelohe, ka wai, ka mahu a me nā kahua ʻē aʻe. ʻOi loa i kekahi mau manawa e pono ai ke kū i ke kaomi kiʻekiʻe a me ka mahana kiʻekiʻe, he koho pono kēia mea. Eia kekahi, hoʻohana pinepine ʻia nā paipu kila humuhumu ASTMA53GR.B i nā kemika, ka mana uila, ke kūkulu ʻana a me nā ʻoihana ʻē aʻe e hāʻawi i nā mea paipu hilinaʻi no nā ʻōnaehana hoʻouna wai like ʻole.
Koho ʻana a me ka mālama ʻana i ka paipu kila humuhumu ASTMA53GR.B
1. Nā hana palekana i ke kūʻai ʻana
I ke kūʻai ʻana i ka paipu kila humuhumu ASTMA53GR.B, pono ʻoe e hoʻolohe i nā mea aʻe:
(1) E koho i nā mea hana maʻamau e hōʻoia i ka maikaʻi o ka huahana hilinaʻi;
(2) E nānā inā ua kūlike nā kikoʻī, nā ana a me ka mānoanoa o ka paia o ka paipu kila i nā koi;
(3) E nānā i ka maikaʻi o ka ʻili o ka paipu kila e hōʻoia i ʻaʻohe hemahema a hōʻino paha i ʻike ʻia;
(4) E koho i nā mea paipu kila kūpono a me nā kikoʻī e like me ke kaiapuni hoʻohana a me nā koi.
2. Nā hana palekana mālama
I ka wā e hoʻohana ai i ka paipu kila humuhumu ASTMA53GR.B, pono ʻoe e hoʻolohe i nā mea aʻe:
(1) E nānā mau a mālama i nā paipu e ʻike a hoʻoponopono i nā pilikia i ka manawa kūpono;
(2) E mālama i nā paipu i maʻemaʻe a maloʻo hoʻi e pale aku i ka pala o loko a me waho o nā paipu;
(3) I ka wā o ka halihali a me ke kau ʻana, pono e uku ʻia ka makaʻala i ka pale ʻana i ka pipeline e pale aku i ka ulia a me ka hōʻino ʻana;
(4) Pono e hoʻololi a hoʻoponopono ʻia nā paipu kila i hōʻino ʻia i ka manawa kūpono e hōʻoia i ka palekana a me ke kūpaʻa o ka ʻōnaehana paipu.
I ka hōʻuluʻulu ʻana, ʻo ka paipu kila humuhumu ASTMA53GR.B he mea paipu me ka hana maikaʻi loa a me nā kahua noi ākea. I ka wā e hoʻohana ai, pono ʻoe e makaʻala i nā pilikia kūʻai a me ka mālama ʻana e hōʻoia i ka palekana a me ke kūpaʻa o ka ʻōnaehana paipu. Me ka hoʻomohala mau ʻana o ka ʻepekema a me ka ʻenehana, e hoʻohana ʻia ka paipu kila humuhumu ASTMA53GR.B ma nā kahua he nui, e lawe mai ana i ka ʻoluʻolu a me nā pono i ka hana kanaka a me ke ola.
