Aia ka ʻokoʻa ma waena o ka paipu laina X52 a me X52N i kā lākou mau kikoʻī a me nā noi i manaʻo ʻia:
X52 Line Paipu: X52 e pili ana i ka pae o ka paipu laina i hoʻohana ʻia ma ka ʻoihana ʻaila a me ka ʻea. He inoa ia i hoʻohana ʻia no ka hoʻokaʻawale ʻana i kahi ʻano paipu kila me ka ikaika haʻahaʻa haʻahaʻa o 52,000 psi (paona i kēlā me kēia square square). Hoʻohana mau ʻia kēia ʻano paipu no ka lawe ʻana i ka aila, ke kinoea, a me ka wai ma nā paipu like ʻole.
X52N Line Pipe: ʻO ka hoʻohui ʻana o ka "N" maʻamau e hōʻike ana ua hoʻoponopono ʻia ka paipu. ʻO ka Normalization kahi hana hoʻomaʻamaʻa wela i hoʻohana ʻia no ka hoʻomaikaʻi ʻana i nā ʻano mechanical o ke kila, e like me kona paʻakikī a me ka ikaika. Ua hana ka paipu laina X52N i kēia kaʻina hana maʻamau, hiki ke hoʻonui i kāna hana ma lalo o kekahi mau kūlana, e pili ana i ka hopena o ka hopena a me ka ductility.
Papa X52 vs. Papa X52N
ʻO X52 a me X52N nā māka ʻelua o ke kila haʻahaʻa haʻahaʻa ikaika kiʻekiʻe (HSLA) i hoʻohana ʻia i ka hana paipu laina no ka ʻoihana ʻaila a me ke kinoea. ʻO ka ʻokoʻa mua ma waena o nā papa ʻelua aia i kā lākou mau koi hou a me nā ʻano hana.
X52 laina paipu he papa maʻamau o HSLA kila e kū ana i nā koi haʻahaʻa i kuhikuhi ʻia ma API 5L (American Petroleum Institute Specification for Line Pipe). Loaʻa iā ia ka ikaika haʻahaʻa haʻahaʻa o 52,000 psi (358 MPa) a kūpono i nā noi pipeline like ʻole.
Ma ka ʻaoʻao ʻē aʻe, ʻo ka paipu laina X52N he mana hou o X52 e hana hou ana i ka hana a hoʻokō i nā koi koʻikoʻi. ʻO ka "N" ma X52N ke kū nei no ka "normalized," e pili ana i kahi kaʻina hana wela e hoʻomaikaʻi ai i nā waiwai mechanical a me ka microstructure o ke kila.
ʻO ka Normalization a me ka Rolling Controlled
Hoʻokomo ʻia ka paipu laina X52N i kahi kaʻina hana maʻamau, e pili ana i ka hoʻomehana ʻana i ke kila i kahi pae wela kikoʻī a laila e ʻae iā ia e hoʻomaha ma ke ʻano hoʻomalu. Kōkua kēia kaʻina hana i ka hoʻomaʻemaʻe i ke ʻano o ke kila, hoʻomaikaʻi i kona ikaika, paʻakikī, a me ka ductility.
Ma waho aʻe o ka hana maʻamau, hiki i ka paipu laina X52N ke hoʻopaʻa ʻia i ka ʻōwili ʻia ʻana, kahi kaʻina e pili ana i ka mālama pono ʻana i ka mahana, ka hoʻohaʻahaʻa ʻana, a me ka papa hana ʻōwili i ka wā hana. ʻO ka ʻōwili ʻia ʻana e hoʻomaikaʻi hou aku i nā waiwai mechanical o ke kila ma ka hoʻolaha ʻana i kahi microstructure maikaʻi.
Kaulike Kalapona a me ka paakiki ha'iha'i
X52N laina paipu maʻamau loaʻa ka haʻahaʻa kalapona like waiwai hoʻohālikelike i X52 laina paipu. ʻO ke kalapona like ke ana o ka paʻakikī a me ka weldability o ke kila, me nā waiwai haʻahaʻa e hōʻike ana i ka maikaʻi o ka weldability a me ke kū'ē ʻana i ka haki ʻana i ka hydrogen.
ʻO ka like kalapona haʻahaʻa o ka paipu laina X52N, i hui pū ʻia me ke kaʻina hana maʻamau, e hoʻomaikaʻi i ka paʻakikī haʻihaʻi. ʻO ka paʻakikī o ka haʻihaʻi kahi ana o ke kūʻē ʻana o ka mea i ka hoʻolaha ʻana a he mea nui e noʻonoʻo ai no ka palekana o ka pipeline, ʻoi aku hoʻi ma nā wahi ʻino a i ʻole nā wahi me ka hana seismic.
ʻO Charpy V-Notch Impact Test
ʻO ka hōʻike hopena Charpy V-Notch kahi ala i hoʻohana nui ʻia e loiloi i ka paʻakikī a me ka ductility o nā mea i nā mahana like ʻole. ʻO ka paipu laina X52N ka mea maʻamau i ʻoi aku ka kiʻekiʻe o Charpy V-Notch hopena ikehu waiwai ma nā mahana i hoʻohālikelike ʻia me ka paipu laina X52. He mea koʻikoʻi kēia paʻakikī i hoʻonui ʻia no nā pipeline e hana ana i nā wahi anu a i ʻole nā ʻāpana me nā loli wela.
Nā noi: X52 a me X52N Line Pipe
X52 laina paipu hoʻohana nui ʻia i nā noi pipeline like ʻole, me nā laina hōʻiliʻili, nā laina hoʻouna, a me nā laina hoʻolaha no ka lawe ʻana i ka aila a me ke kinoea. Hāʻawi ia i kahi kaulike maikaʻi o ka ikaika, paʻakikī, a me ka uku-pono no nā papahana pipeline.
ʻO ka paipu laina X52N, me kona mau ʻano mechanical i hoʻonui ʻia a me ka paʻakikī, makemake pinepine ʻia no nā noi koi a i ʻole nā hoʻokomo ʻana i nā wahi paʻakikī. Hoʻohana maʻamau ia i nā paipu e hele ana i nā ʻāina paʻakikī, e like me nā ʻāina mauna, nā wahi me ka hana seismic, a i ʻole nā ʻāpana me nā ʻano wela wela. Hoʻohana ʻia ka paipu laina X52N no nā pipeline o waho, kahi i hoʻokau ʻia ai ka pipeline i nā koʻikoʻi kiʻekiʻe a me nā kūlana kūlohelohe.
Nā Kūlana Pipeline
Nā kumu hana
He kuleana koʻikoʻi ke kaiapuni hana o kahi pipeline i ka hoʻoholo ʻana i ka pae kūpono o ka paipu laina. ʻOi aku ka maikaʻi o ka paipu laina X52N no nā kaiapuni paʻakikī ma muli o ka hoʻomaikaʻi ʻana i ka paʻakikī haʻihaʻi a me ke kūʻē ʻana i ka hoʻolaha ʻana.
Ma nā ʻāpana me nā ʻano wela wela a i ʻole nā wahi wela haʻahaʻa, makemake ʻia ka paipu laina X52N ma muli o kona ʻoi aku ka paʻakikī i nā haʻahaʻa haʻahaʻa, e like me ka hōʻike ʻana e kāna mau waiwai ikehu hopena Charpy V-Notch.
Pēlā nō, ma nā wahi e pili ana i ka hana seismic a i ʻole me ka ʻāina paʻakikī, hiki ke koho ʻia ka paipu laina X52N no kona kūpaʻa maikaʻi ʻana i ka hoʻolaha ʻana a me ka hoʻomaikaʻi ʻana i ka paʻakikī haʻihaʻi, e hōʻoia i ka palekana a me ka pololei o ka pipeline.
Kālā a me ka loaʻa
ʻOiai ke hāʻawi nei ka paipu laina X52N i nā waiwai mechanical i hoʻonui ʻia, hiki mai ia ma ke kumukūʻai kiʻekiʻe ma mua o ka paipu laina X52. ʻO nā kaʻina hana hou e pili ana i ka normalization a me ka hoʻokele kaʻa ʻana e kōkua i ka piʻi ʻana o ke kumukūʻai.
Hiki ke kaupalena 'ia ka loa'a o ka paipu laina X52N i ka paipu laina X52 i hana nui 'ia. Pono nā mea hoʻohana paipu a me nā mea ʻaelike e noʻonoʻo i ka nānā ʻana i ka uku-pono a me nā koi o ka papahana i ka wā e hoʻoholo ai ma waena o ka paipu laina X52 a me X52N.
