No ke aha i ʻokoʻa ai nā kumukūʻai o A105 a me Q235?

Hoʻohana nui ʻia nā flanges carbon steel i ka hoʻokomo ʻana i nā pipeline wai ʻoihana. Q235 aA105 ʻelua ʻano mea hao kalapona i hoʻohana mau ʻia. Eia naʻe, ʻokoʻa kā lākou mau ʻōlelo, ʻokoʻa loa i kekahi manawa. No laila he aha ka ʻokoʻa ma waena o lākou? He aha ka ʻokoʻa ma waena o kā lākou mau kumukūʻai?

ʻO ka mea mua, ʻo Q235 carbon steel flange he flange maʻamau i koho ʻia e nā mea kūʻai aku ma muli o kona kumukūʻai haʻahaʻa.Q235 hoʻohana maʻamau i kahi mahana o - 10~350 ℃. Eia kekahi, koi maʻamau ka Q235 i kahi kaomi hoʻolālā ma lalo o 3.0MPa. Ma ke ʻano o ka hoʻohana ʻana,

Hoʻohana pinepine ʻia ka flange kalapona Q235 ma luna o ka pipeline non-toxic a ʻaʻole hiki ke hoʻopau ʻia, a ʻoiaʻiʻo hoʻi, hoʻohana ʻia ia ma ke kila structural, e like me nā kākoʻo a me nā hangers, etc. ʻO ke kiʻekiʻe o ka lāʻau ʻawaʻawa ʻo ia ka mea ʻona a weliweli loa.

Hana ʻia ka flange kalapona i ka mea Q235. E hoʻomaopopo ʻo ia ke ʻano o ka forging Q235, no ka mea, hiki ke hoʻohana pololei ʻia ka pā kila Q235 mānoanoa e like me ka flange, akā ʻoi aku ka haʻahaʻa o kāna hana ma mua o ka forging. ʻO ka mea nui ma muli o ka ʻokoʻa o ka hoʻolālā aniani i loko, he paʻakikī ke hoʻokaʻawale ma waena o ka haku mele a me ka hana. ʻO ke kumu o Q235 no ka mea ʻoi aku ka ikaika o ka hua ma luna o 235, ʻoi aku ka ikaika o ke ana ʻana i nā waiwai mechanical ma luna o 245, a ʻoi aku ka ikaika tensile ma luna o 265.

A105 kalapona kila flangehe mea ma'amau 'Amelika ma'amau kalapona kila, ma'amau structural kila, e like me ka pā kila, profile kila, etc. Kona manganese maʻiʻo mea kiʻekiʻe, a me ka poepoe kila mea i kapaia 20Mn. Hiki ke ʻike ʻia he kiʻekiʻe kona ʻike ma hope o ka manganese element. Mai ia manawa, ʻoi aku ka kiʻekiʻe o kona ikaika tensile a me ka ikaika hoʻohua, a ʻoi aku ka maikaʻi o kāna mau waiwai mechanical. ʻO ka ikaika maoli o ka waiwai A105 ma lalo o nā kūlana maʻamau ma mua o 300, a ʻoi aku ka ikaika tensile ma mua o 500.

Ma ke kālepa kūʻai aku o Kina i nā ʻāina ʻē, nui nā mea kūʻai aku a me nā mea kūʻai aku e koho i nā mea flange o ka maʻamau maʻamau ʻAmelika A105. Inā he mau mea ʻē aʻe, e hana ʻia nā ʻōlelo kūikawā.
