ʻO API 5L PSL1 (Pipeline Specification Level 1) e pili ana i kahi pae kikoʻī o ka API 5L kikoʻī no nā paipu laina i hoʻohana ʻia i ka lawe ʻana i ka aila, kinoea, a me nā wai ʻē aʻe i loko o ka ʻoihana ʻaila a me nā kinoea maoli. ʻO PSL1 ka pae kumu loa o ka API 5L kikoʻī, a hoʻonohonoho ia i nā koi liʻiliʻi no ka hana ʻana, ka haku mele, nā waiwai mechanical, hoʻāʻo, a me ka nānā ʻana i nā paipu laina.
Eia kekahi mau hiʻohiʻona nui o API 5L PSL1 paipu:
Ke Kaʻina Hana Hana: Hiki ke hana ʻia nā paipu PSL1 ma o ke kaʻina hana ʻole a welded paha.
Ka ho'āʻo a me ka nānā ʻana: PSL1 paipu e hana i nā hoʻokolohua like ʻole a me ka nānā ʻana e hōʻoia i ko lākou maikaʻi a me ka kūpaʻa, me ka hoʻāʻo hydrostatic, ka hoʻāʻo uila non-destructive, flattening test, and bend test, a me nā mea ʻē aʻe.
Hoʻohana: Hoʻohana ʻia nā paipu PSL1 no ka lawe ʻana i ka aila, ke kinoea, a me nā wai ʻē aʻe i loko o nā pipeline ma luna o nā ʻoihana like ʻole, ka helu ʻana i ka ʻaila, ke kinoea maʻamau, a me nā ʻoihana petrochemical.
API 5L PSL1 paipu hāʻawi i kahi hoʻonohonoho maʻamau a paʻa no ka hoʻomohala ʻana i nā paipu, a me ka hui ʻana i nā mea e pono ai no ka palekana, ka paʻakikī, a me ka hoʻokō ʻana i nā noi lawe wai.
API 5L PSL1 Paipu kiko'ī:
API 5L PSL1 paipu e pili ana i ka loiloi kūikawā o ka paipu laina kila e pili ana i nā hoʻoholo i kau ʻia ma ka American Petroleum Institute's (API) Standard 5L, e lawelawe ana i ka hana ʻana i ka paipu laina no ka lawe ʻana i ka aila i hoʻomaʻemaʻe ʻole ʻia, ke kinoea maʻamau, a me nā mea aila ʻē aʻe. ʻO ka inoa PSL1 ke kū nei no "Product Specification Level 1," e hōʻike ana i ka pae kumu o nā koi no ka paipu laina ma lalo o API 5L.
Hoʻolālā ʻia ia e hoʻokō i nā koi liʻiliʻi no ka ikaika hoʻohua, ka ikaika tensile, a me nā waiwai paʻakikī, a me nā hoʻomanawanui dimensional a me ka haku mele. Hoʻohana nui ʻia kēia mau paipu i nā noi haʻahaʻa haʻahaʻa, e like me nā laina hōʻiliʻili, nā laina hoʻolaha, a me nā laina hoʻouna haʻahaʻa haʻahaʻa.
Hoʻohālikelike ʻia me nā māka PSL ʻē aʻe i loko o ka API 5L, e like me PSL2 (kahi pae ikaika kiʻekiʻe) a me PSL3 (kahi pae ʻoi aku ka paʻakikī no ka lawelawe ʻawaʻawa), ʻoi aku ka liʻiliʻi o ka paipu PSL1 no nā waiwai mechanical a me ka haku mele. Eia nō naʻe, pili mau ia i nā kūlana kumu i hoʻonohonoho ʻia e API 5L, e hōʻoia ana i ka maikaʻi a me ka hana no kāna mau noi i manaʻo ʻia.
Aia nā kikoʻī no nā paipu API 5L PSL1 i nā ʻāpana like ʻole e like me ke ana, ka haku mele, nā waiwai mechanical, nā koi hoʻāʻo, a me nā koina nānā.
Nui: Loaʻa nā paipu PSL1 i nā ʻano nui, i kuhikuhi ʻia e ka nui o ka paipu nominal (NPS) a me ka hoʻonohonoho (SCH). Uhi maʻamau ka nui o nā anawaena a me nā mānoanoa pā kūpono no nā noi like ʻole.
Ka Hoʻohui Kemika: Ua kuhikuhi ʻia kona haku mele e ka API 5L maʻamau. Loaʻa nā palena o nā mea e like me carbon (C), manganese (Mn), phosphorus (P), sulfur (S), silicon (Si), a me nā mea ʻē aʻe. ʻO nā koi hoʻohui e hōʻoia i nā waiwai i makemake ʻia a me ka hana o nā paipu.
Mechanical Properties: Aia nā paipu API 5L PSL1 i ka liʻiliʻi o ka ikaika a me nā koi ikaika tensile kiʻekiʻe, e ʻokoʻa ana ma muli o ka pae o ka paipu. ʻO nā waiwai mechanical e hōʻoia i ka hiki i nā paipu ke kū i nā kūlana hana i manaʻo ʻia, me ke kaomi, ka mahana, a me nā mea kūlohelohe.
Nā Koina Hoʻāʻo: Hoʻokomo ʻia nā paipu PSL1 i nā hoʻokolohua like ʻole e hōʻoia i ko lākou maikaʻi a me ka pololei. ʻO nā hoʻāʻo maʻamau ka hoʻāʻo hydrostatic, ka hoʻāʻo uila non-destructive (e like me ka ultrasonic a i ʻole electromagnetic inspection), hoʻāʻo palahalaha, a me ka hoʻāʻo piko. Ke loiloi nei kēia mau hoʻāʻo ʻana i ka hiki i nā paipu ke kū i ke kaomi, ʻike i nā hemahema, a hōʻoia i ka hoʻokō dimensional.
Nā Kūlana Nānā: Pono nā paipu PSL1 i ka nānā ʻana e hōʻoia i ka hoʻokō ʻana i nā koi i kuhikuhi ʻia. Hiki i nā nānā ke komo i ka nānā ʻike maka, nā ana ana, ka loiloi ʻana i ke ʻano o ka ʻili, a me ka loiloi palapala. E hōʻoia ka ʻike ʻana i nā paipu i nā kūlana i kuhikuhi ʻia a me nā koi hōʻoia maikaʻi.
Manaʻo nā kikoʻī no nā paipu API 5L PSL1 e hōʻoia i ka maikaʻi, ka hana, a me ka palekana o nā paipu laina i hoʻohana ʻia i ka lawe ʻana i ka aila, ke kinoea, a me nā wai ʻē aʻe i loko o nā ʻoihana ʻaila a me nā kinoea maoli.
Nā Pono Mīkini:
ʻO nā waiwai mechanical o ka paipu API 5L PSL1 he mau mea koʻikoʻi e hoʻoholo ai i kona kūpono no nā noi like ʻole. ʻO nā waiwai mechanical nui e komo pū me:
Ka ikaika o ka hua: Loaʻa iā ia ka ikaika hua haʻahaʻa haʻahaʻa mai ka 24,000 psi (165 MPa) a i ka 42,000 psi (290 MPa), e pili ana i ka mānoanoa o ka pā.
Ka ikaika tensile: ʻO ka palena haʻahaʻa o ka ikaika tensile no ka API 5L PSL1 paipu mai ka 48,000 psi (331 MPa) a i ka 70,000 psi (483 MPa), e hōʻoia ana i ka paipu ke kū i nā ukana tensile me ka ʻole o ka hemahema.
Elongation: Pono ia e hoʻokō i nā koi elongation liʻiliʻi, maʻamau mai 15% a 25%, e pili ana i ka pae paipu a me ka mānoanoa o ka paia. ʻO ka elongation kahi ana o ka ductility o ka paipu, he mea nui ia no ka pale ʻana i ka deformation me ka ʻole o ka haki ʻana a i ʻole ka haki ʻana.
Hāʻawi kēia mau waiwai mechanical i ka hana holoʻokoʻa a me ka hilinaʻi o ka paipu API 5L PSL1 i nā noi like ʻole. ʻO ka hāʻawi kūpono a me ka ikaika tensile e hōʻoia i ka paipu ke kū i nā kaomi o loko a me nā ukana o waho me ka ʻole o ka deformation nui a i ʻole ka hāʻule ʻole. ʻO ka hoʻolōʻihi pono ʻana e hiki ai i ka paipu ke hoʻokomo i kekahi ʻano o ke koʻikoʻi me ka ʻole o ka palupalu a i ʻole ka pohā.
Hoʻohālikelike i nā papa paipu ʻē aʻe:
ʻOiai ua hoʻolālā ʻia ka paipu API 5L PSL1 no nā noi haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o nā pae paipu ʻē aʻe no nā noi kiʻekiʻe-koʻikoʻi a i ʻole nā noi kūikawā.
API 5CT: Hoʻopili kēia kikoʻī i ka pahu a me nā paipu i hoʻohana ʻia i ka hana ʻaila a me ke kinoea. Hoʻohana maʻamau ʻia ka paipu API 5CT no ka hoʻoheheʻe maikaʻi, ka paipu hana, a me nā noi downhole ʻē aʻe kahi e koi ʻia ai ka ikaika kiʻekiʻe a me ke kūpaʻa corrosion.
ASTM A106: Hoʻopili kēia kikoʻī i ka paipu kila carbon seamless no ka lawelawe wela kiʻekiʻe. Hoʻohana pinepine ʻia ka paipu ASTM A106 i nā mea kanu mana, nā refineries, a me nā keʻena hana kemika kahi e kū ai nā mahana kiʻekiʻe a me nā paʻakikī.
I ke koho ʻana i ka pae paipu kūpono, pono e noʻonoʻo ʻia nā mea e like me ke kaomi hana, ka mahana, ka hoʻohuihui wai, a me nā kūlana kaiapuni. Hiki paha i ka paipu API 5L PSL1 ke kūpono no nā noi haʻahaʻa haʻahaʻa, ʻaʻole-corrosive, ʻoiai ʻoi aku ka ikaika o nā koi e pono ai ka hoʻohana ʻana i nā paipu kiʻekiʻe e like me API 5CT a i ʻole ASTM A106.
API 5L PSL1 Paipu Mea Hana:
He mea hana kaulana ʻo LONGMA GROUP o ka paipu API 5L PSL1, e hāʻawi ana i kahi ākea o nā māka, me B, X42, X46, X52, X56, X60, X65, X70, a me X80. ʻO kā lākou mau huahana paipu API 5L PSL1 he anawaena o waho mai ka 1/2 "a 72" a me ka mānoanoa o ka paia mai SCH10 a i SCH160.
Hoʻopili ʻia ka paipu LONGMA GROUP me nā palapala hōʻoia kūpono, e like me ka API 5L Certificate, ISO Certificate, a me QMS Certificate, e hōʻoia ana i ka hoʻokō ʻana i nā kūlana ʻoihana a me nā ʻōnaehana hoʻokele maikaʻi.
No ka poʻe e ʻimi nei i nā mea hana paipu API 5L PSL1 pono, hiki ke hoʻopili ʻia ʻo LONGMA GROUP ma info@longma-group.com no ka ninau a me ke kauoha.
