X60 Line Pipe, Mechanical Properties O

X60 Line Pipe, Hoʻokaʻawale ʻia ka hoʻomaʻamaʻa ʻana i ka wela i ʻelua mau ʻāpana, ʻo ka hoʻomaʻamaʻa wela kemika, ʻo ka hoʻopau ʻana i ka ʻili a me ka mālama ʻana i ka wela, ʻo ke ʻano o ka hoʻāʻo paʻakikī penei:

[1] Lapaʻau wela kemika o ka paipu X60
- ʻO ka hoʻomaʻamaʻa wela kemika e hana i ka ʻili o ka paipu pipeline X60 e hoʻokomo i hoʻokahi a i ʻole kekahi mau ʻāpana kemika, i mea e hoʻololi ai i ka haku mele, ke ʻano a me nā waiwai o ka ʻili o ka paipu paipu X60.Ma hope o ka hoʻopau ʻana a me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ʻo ka ʻili o ka paipu pipeline X60 he kiʻekiʻe paʻakikī, hoʻopaʻa kūʻē a hoʻopili i ka ikaika luhi, a ʻo ke kumu o ka paipu pipeline X60 he ikaika kiʻekiʻe a paʻakikī.

-- ʻO nā palena ʻenehana nui o ka hoʻomaʻamaʻa wela kemika X60 pipeline ka hohonu o ka papa paʻakikī a me ka paʻakikī o ka ʻili.Pono e ho'āʻo ʻia ka hohonu o ka papa paʻakikī e vickers hardness tester.E ana i ka mamao mai ka ʻili paipu X60 a hiki i kahi e hāʻule ai ka paʻakikī i 50HRC.ʻO kēia ka hohonu hohonu o ka hoʻomaʻamaʻa ʻana i ka wela kemika o ka X60 pipeline tube surface hardness testing and surface hardening heat treatment ka paʻakikī o ka X60 pipeline tube detection, hiki ke hoʻohana i ka vickers hardness tester, surface rockwell hardness tester a i ʻole rockwell hardness tester e hoʻāʻo ai, ʻo ka mea wale nō. ʻO ka mānoanoa o ka nitriding mānoanoa lahilahi, maʻamau ʻaʻole ʻoi aku ma mua o 0.7 mm, a laila ʻaʻole hiki ke hoʻohana hou i ka mea hōʻike paʻakikī rockwell, hiki ke hoʻohana ʻia ka Microhardness tester.

[2] X60 pipeline ili ili a me ka hoʻomaʻamaʻa wela
- ʻO ka hoʻopau ʻana i ka ʻili a me ka mālama ʻana i ka wela e hana maʻamau ʻia e ka hoʻomehana induction a i ʻole ka wela wela.ʻO nā palena ʻenehana nui ka paʻakikī o ka ʻili, ka paʻakikī kūloko a me ka hohonu o ka papa paʻakikī.Hiki ke hoʻohana ʻia ʻo Vickers hardness tester no ka hoʻāʻo ʻana i ka paʻakikī, rockwell a i ʻole ka ʻili o ka Rockwell hardness tester.ʻO ke koho ʻana i ka ikaika hoʻāʻo (kaulike) pili i ka hohonu o ka papa paʻakikī kūpono a me ka paʻakikī o ka ʻili o ka pipeline X60.ʻEkolu ʻano ʻano mika paʻakikī.

He mea nui ka Vickers hardness tester e ho'āʻo ai i ka paʻakikī o ka ʻili o ka paipu paipu X60 i mālama ʻia.Hiki iā ia ke hoʻohana i ka ikaika hoʻāʻo 0.5 ~ 100kg e hoʻāʻo i ka papa paʻakikī o ka ʻili e like me ka 0.05mm.ʻO kona pololei ka mea kiʻekiʻe loa, a hiki iā ia ke hoʻokaʻawale i ka ʻokoʻa iki o ka paʻakikī o ka ʻili o ka wela i mālama ʻia X60 pipeline paipu.Eia hou, ua ana ka hohonu o ka papa paakiki pono e ka vickers hardness tester, no laila, pono e hoʻolako i kahi mea ho'āʻo paʻakikī Vickers no nā'āpana e hoʻokō i ka wela wela a hoʻohana paha i kahi helu nui o ka hana wela wela.

-- He kūpono loa ka mea hōʻike paʻakikī o Surface Rockwell no ka hoʻāʻo ʻana i ka paʻakikī o ka paipu paipu X60 paʻakikī.ʻEkolu mau unahi no ka mea hōʻike paʻakikī ʻo Rockwell e koho mai.Hiki ke ho'āʻo i nā ʻano laina X60 paʻakikī o ka ʻili me ka hohonu o ka paʻakikī ma mua o 0.1mm.ʻOiai ʻaʻole kiʻekiʻe ke kiʻekiʻe o ka hoʻāʻo paʻakikī o Rockwell e like me ka vicker hardness tester, hiki iā ia ke hoʻokō i nā koi e like me ke ʻano hoʻāʻo no ka hoʻokele maikaʻi a me ka nānā ʻana i ka conformity i nā mea kanu mālama wela.Eia kekahi, loaʻa iā ia nā ʻano o ka hana maʻalahi, ka hoʻohana maʻalahi, ke kumu kūʻai haʻahaʻa, ke ana wikiwiki, a hiki ke heluhelu pololei i ka waiwai paʻakikī, etc. hoʻāʻo luku.He mea koʻikoʻi kēia no ka hana ʻana o ka pipeline X60 a me nā mea kanu mīkini.

-- Hiki ke hoʻohana ʻia ka mea hōʻike paʻakikī ʻo Rockwell ke mānoanoa ka papa paʻakikī o ka ʻili.I ka 0.4 ~ 0.8mm ka mānoanoa o ka papa paʻakikī o ka wela, hiki ke hoʻohana ʻia ka unahi HRA, ke ʻoi aku ka mānoanoa o ka papa paʻakikī ma mua o 0.8mm, hiki ke hoʻohana ʻia ka pālākiō HRC.

-- Hiki ke hoʻololi maʻalahi ʻia nā waiwai paʻakikī o Vickers, Rockwell a me Surface Rockwell i mau waiwai paʻakikī maʻamau, kaha kiʻi a mea hoʻohana paha.Hāʻawi ʻia nā papa hoʻololi kūpono i nā kūlana honua ISO, maʻamau ʻAmelika ASTM a me GB/T maʻamau Kina.

[3] Hoʻoponopono wela kūloko
-- Inā koi ʻia ka paʻakikī kūloko o nā ʻāpana e kiʻekiʻe, hiki ke hoʻokō ʻia ka hoʻomaʻamaʻa ʻana i ka wela wela kūloko e ka hoʻomehana induction a me nā ʻano hana ʻē aʻe.Pono ia mau paipu paipu X60 e hoailona i ka wahi o ka lapaau ana i ka wela o ka aina a me ka waiwai paakiki ma ke kii.E hana ʻia ka hoʻāʻo paʻakikī o ka paipu X60 ma kahi i koho ʻia.Hiki i ka mea ho'ā'o pa'akikī ke ho'ohana i ka mea ho'ā'o pa'akikī o Rockwell, ho'ā'o i ka waiwai pa'akikī HRC, e like me ka papapa'u o ka ho'oma'ema'e wela, hiki ke ho'ohana i ka mea hō'ike pa'akikī o Rockwell, ho'ā'o i ka waiwai pa'akikī HRN.
