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,

Q235 carbon steel flange ua hoʻohana maʻamau ma non-toxic a non-combustible pipeline medium, a 'oiaʻiʻo, ua hoʻohana 'ia ma ka structural kila, e like me ke kākoʻo a me ka hangers, etc., akā, Q235 e ole e hoʻohana no liquefied hydrocarbon, a 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 i ke ʻano o ka hana ʻana i ka Q235, no ka mea hiki ke hoʻohana pololei ʻia ka pā kila Q235 ma ke ʻano he 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 hoʻokuʻu 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.
