I ka honua o ka hoʻomohala ʻana i ka ʻaila a me ke kinoea, ʻo ka hoʻoholo ʻana i ka loiloi paipu laina kūpono he mea nui ia no ka hōʻoiaʻiʻo ʻana i nā hana palekana a huahua. ʻElua mau māka i hoʻohana pinepine ʻia ʻo X42 a me X52, i hōʻike ʻia ma lalo o ka American Petroleum Institute (API) Specification 5L. ʻOiai ke kaʻana like nei kēia mau māka, aia kekahi mau ʻokoʻa like ʻole e pili ana i ka maikaʻi o ka hāʻawi liʻiliʻi ʻana, nā noi, a me nā kikoʻī. ʻO ka hoʻomaopopo ʻana i kēia mau ʻokoʻa he kumu ia no ka hana ʻana i nā koho hoʻonaʻauao ke hoʻolālā a kūkulu ʻana i nā ʻōnaehana pipeline.
X52 laina paipu a X42 laina paipu ʻelua mau pae ʻokoʻa o nā paipu kila e pili ana i ka API 5L kikoʻī no nā paipu laina i hoʻohana ʻia i ka ʻoihana ʻaila a me ke kinoea. ʻOiai kaʻana like lākou, loaʻa iā lākou nā ʻokoʻa like ʻole e pili ana i kā lākou mau waiwai mechanical, haku mele a me nā noi. Eia ka hoʻohālikelike ma waena o nā paipu laina X52 a me X42:
Grade:
X42: ʻO ka "X" ma X42 e hōʻike ana he pae paipu laina ikaika loa i loko o ka kikoʻī API 5L. ʻO ka helu "42" ke hōʻike nei i ka ikaika haʻahaʻa haʻahaʻa o ka paipu ma nā kaukani paona i kēlā me kēia ʻīniha kuea (ksi), ʻo ia hoʻi ma kahi o 42,000 psi.
X52: Pēlā nō, hōʻike ka "X" i ka X52 i kahi pae paipu laina ikaika kiʻekiʻe, me ka helu "52" e hōʻike ana i ka ikaika haʻahaʻa haʻahaʻa o ka paipu, ma kahi o 52,000 psi.
Nā Pono Mīkini:
X42: ʻO ka ikaika haʻahaʻa loa o ka paipu laina X42 he 42,000 psi (290 MPa), me ka ikaika tensile haʻahaʻa o 60,000 psi (415 MPa) a me ka elongation liʻiliʻi o 23%.
X52: ʻO ka ikaika liʻiliʻi loa o ka paipu X52 he 52,000 psi (360 MPa), me ka ikaika tensile haʻahaʻa o 66,700 psi (460 MPa) a me ka elongation liʻiliʻi o 21%.
Ke mele haku mele:
Loaʻa i nā paipu X42 a me X52 nā koi hoʻohui kemika kikoʻī i hōʻike ʻia ma ka kikoʻī API 5L. ʻOiai ʻokoʻa iki ka haku mele ma waena o nā mea hana, ʻo nā papa ʻelua he mau mea e like me carbon, manganese, phosphorus, sulfur, silicon, niobium, titanium, a me vanadium i loko o nā palena i kuhikuhi ʻia.
Uku a me ka loaʻa:
ʻO ka maʻamau, ʻoi aku ka maikaʻi o ka paipu X52 ma mua o ka paipu laina X42 ma muli o kona ikaika kiʻekiʻe a me nā ʻano hana. Hiki ke ʻokoʻa ka loaʻa ʻana ma muli o ka makemake o ka mākeke a me nā kumu kūloko.
Ka ikaika hua liʻiliʻi
ʻO ka ikaika haʻahaʻa haʻahaʻa kahi hiʻohiʻona nui e hoʻokaʻawale i nā paipu laina X42 a me X52. Hōʻike ia i ka pae koʻikoʻi haʻahaʻa kahi e hoʻomaka ai ka hoʻoheheʻe ʻana o ka mea paipu i ka plastically a mau loa paha.
a. ʻO ka liʻiliʻi loa o ka ikaika X42 laina paipu he 42,000 psi (290 MPa).
b. ʻO ka liʻiliʻi loa o ka ikaika X52 laina paipu he 52,000 psi (360 MPa).
ʻO kēia ikaika kiʻekiʻe i ka paipu laina X52 hiki iā ia ke pale aku i nā kaomi o loko a me nā ukana waho me ka ʻole o ka ʻike ʻana i ka deformation mau. ʻO ka hopena, makemake pinepine ʻia ka paipu laina X52 no nā noi e koi ana i nā koina hana kiʻekiʻe a i ʻole nā koi palekana.
noi
ʻO ke koho ʻana o ka paipu laina X42 a i ʻole X52 e alakaʻi pinepine ʻia e ka noi kikoʻī a me nā kūlana hana o ka ʻōnaehana pipeline.
a. Nā Paipu laina X42:
Hoʻohana pinepine ʻia nā paipu laina X42 i nā paipu hoʻouna ʻaila a me ke kinoea, ʻoi loa no nā paipu kila welded. Hāʻawi lākou i ka hana welding maikaʻi, he mea koʻikoʻi ia no ka hōʻoia ʻana i nā pili pono a me ka leak-leak i ka wā o ke kūkulu ʻana i ka pipeline. He kūpono nā paipu laina X42 no nā noi kaomi haʻahaʻa a hoʻohana nui ʻia i nā pipeline cross-country a me nā ʻōnaehana hōʻiliʻili.
b. Nā Paipu laina X52:
Hoʻolālā ʻia nā paipu laina X52 no nā noi kiʻekiʻe kiʻekiʻe a loaʻa ka weldability maikaʻi loa a me ka formability. ʻO ko lākou ikaika hoʻonui e hiki ai iā lākou ke pale aku i nā koʻikoʻi o loko a me nā haʻahaʻa o waho, e kūpono iā lākou no nā noi kahi e koi ʻia ai nā kaomi hana kiʻekiʻe. Hoʻohana pinepine ʻia nā paipu laina X52 i nā pipeline lōʻihi, nā pipeline o waho, a me nā ʻōnaehana hoʻoiho kiʻekiʻe.
Nā kikoʻī a me nā ana
Hāʻawi ka API 5L maʻamau i nā pae kikoʻī huahana kikoʻī (PSL) a me nā koi dimensional no nā paipu laina X42 a me X52.
a. X42 Line Paipu Nā kikoʻī a me nā ana:
- Nā Kūlana Kūlana Huahana (PSL): Loaʻa nā paipu laina X42 i nā pae PSL1 a me PSL2, kahi e wehewehe ai i nā koi hoʻāʻo a me ka nānā ʻana.
- Nui: Loaʻa nā paipu laina X42 i nā nui mai 4 iniha a 60 iniha (101.6 mm a 1,524 mm) i ke anawaena o waho.
b. X52 Line Pipe kiko'ī a me ana:
- Nā Kūlana Kūlana Huahana (PSL): E like me X42, hāʻawi nā paipu laina X52 i nā pae PSL1 a me PSL2.
- Nui: Loaʻa nā paipu laina X52 ma kahi ākea o ka nui, maʻamau mai 21.3 millimeters (0.84 iniha) a i 2,500 millimeters (98.43 iniha) ma waho.
He mea nui e hoʻomaopopo i ka kikoʻī kikoʻī a me nā hoʻomanawanui no nā paipu laina X42 a me X52 i kikoʻī ʻia i ka maʻamau API 5L, e hōʻoiaʻiʻo ana i ka hoʻohālikelike a me ka pili ʻana i nā koi ʻoihana.
Mea Hana Paipu Laina API:
ʻAʻole lako wale nō ka LONGMA GROUP X52 laina paipu akā ʻo nā māka ʻē aʻe e like me B, X42, X46, X56, X60, X65, X70, a me X80. Uhi kā lākou laina huahana i nā anawaena o waho mai ka 1/2 iniha a 72 iniha a me ka mānoanoa mai SCH 10 a i SCH 160.
Inā ʻoe e noʻonoʻo nei i nā mea hana paipu laina API, ʻo LONGMA GROUP kahi koho kaulana. Hiki iā ʻoe ke hoʻokaʻaʻike iā lākou ma info@longmagroup.com e kūkākūkā i kāu mau koi papahana a e ʻimi i kā lākou mau makana huahana.
Ke koho ʻana ma waena o nā paipu laina X42 a me X52, pono e loiloi pono i nā mea e like me ke kaomi hana, nā kūlana kūlohelohe, nā ʻano hoʻonohonoho, a me nā koi hoʻoponopono. ʻO ke kūkākūkā me nā poʻe loea akamai a me ka pili ʻana i nā kūlana ʻoihana a me nā hana maikaʻi loa e hiki ke kōkua i ka hōʻoia ʻana i ka palekana a me ka maikaʻi o ka lawe ʻana i ka aila, gas, a me nā wai ʻē aʻe ma o nā ʻōnaehana pipeline.
