He aha ka API 5L:
ʻO ka ʻAmelika Hui Pū ʻIa ʻAmelika (API),i hoʻokumu ʻia i ka makahiki 1919,ʻO ia ka hui ʻoihana ʻaila a me nā kinoea kūlohelohe nui loa ma ʻAmelika Hui Pū ʻIa.
He aha ke ʻano o 5L:
ʻO 5L ke kū i nā kikoʻī o nā paipu kila: - Ma kahi huaʻōlelo, ʻo ka laina API 5L ka paipu kila kalapona i hoʻopili ʻia i ka ʻaila a me ka hoʻoili kinoea.I kēia manawa, hiki i nā wai like ʻole e like me ka mahu, ka wai, ka slurry ke lawe i ka API 5L maʻamau no ka hoʻouna ʻana.Hoʻopili ʻia nā kikoʻī 5L hoʻonohonoho papahana i nā ʻano hui i welded a kūlike.ʻO ka API 5L o ka American Petroleum Institute kikoʻī e uhi i ka paipu laina kila kūpaʻa a welded.ʻO kēia ka paipu kila no nā kaʻa kaʻa paipu i loko o nā ʻoihana ʻaila a me nā kinoea puhi ahi.He kūpono ka polokalamu 5L no ka hāʻawi ʻana i ke kinoea, ka wai, a me ka ʻaila.ʻO ke kikowaena papahana ʻo Spec 5L he International Standard e hoʻoholo i nā koi mua no ka hui ʻana o nā pae kikoʻī ʻelua.
E ʻike hou aku e pili ana iā PSL 1 a me PSL 2:
ʻO PSL 1 a me PSL 2 nā paipu kila kūpaʻa a welded no ka hoʻohana ʻana i nā kaʻa kaʻa kaʻa paipu i nā ʻoihana ʻaila a me ka ʻaila.
Hoʻohana maʻamau ka PSL1 e like me ASTM A106 B a me A53 B.
ʻOi aku ka waiwai o ka PSL2 i ka ikaika kemika a me ka mechanical.ʻOi aku ka nui o ka PSL2 e koi i nā ʻano hoʻokolohua e like me None Distructive Test, CVN Impact Test, DWT etc.
ʻO nā māka i uhi ʻia e kēia kikoʻī, ʻo ia ka papa maʻamau A25,A,B,X42,X46,X52,X56,X60,X65,X70 a me X80;a me nā papa waena.
API 5L ʻIke Nui:
Hāʻawi ka API SPEC 5L kikoʻī i nā kūlana no ka paipu kūpono no ka hoʻohana ʻana i ka lawe ʻana i ke kinoea, ka wai, a me ka ʻaila i loko o ka ʻoihana kinoea a me ka ʻaila.Hoʻopili ka API SPEC 5L i ka paipu laina kila ʻole a welded.Loaʻa iā ia ka paipu plain-end, threaded-end, andbelled-end pipe, a me ka pipe through-the-flowline (TFL), a me ka paipu me nā welau i hoʻomākaukau ʻia no ka hoʻohana ʻana me nā hoʻohui kūikawā.
ʻAʻole hiki ke hoʻololi ʻia ka paipu i hana ʻia i ka ASTM106 Grade A a i ʻole B me API 5L.ʻOi aku ka paʻakikī o nā koi i nā māka API 5L X;ʻAʻole ʻae ʻia nā māka i ʻōwili ʻia a ʻaʻole ʻae ʻia ka hana hou ʻana.Eia kekahi, hāʻawi ʻia ka nānā pono ʻana i nā hoʻāʻo paʻakikī a me ka paʻakikī no nā lawelawe ʻawaʻawa a me nā papa kiʻekiʻe a me nā papa wela.
Nā pae ikaika a me ka desulphurization:
ʻO nā sulphides manganese nā mea hoʻokomo maʻamau i nā kila manganese a pau.No ka mea e hoʻokaʻawale lākou i ka hopena o ka ikaika o ka hopena, pono e hoʻemi ʻia ka ʻike sulphure.
Nā polokalamu API 5L:
ʻO ka lawe ʻana i ke kinoea, ka wai a me ka aila - makemake ʻia i nā paipu lōʻihi ma muli o ke kūʻai ʻole ʻia ʻana o ke kila Pipeline - kūʻē i ka propogation crack.
Ke hoʻohui ʻia ʻo API 5L Gr.b a i ʻole A106 Gr.b paipu kila, hiki ke hoʻololi a hoʻololi ʻia kekahi mau mea kūpono a me nā flanges.Inā ʻo ʻoe ʻoelke koho nei no ka ASTM A105 carbon steel pipe fittings e like me ka paipu paipu, flanges, fasteners and gaskets.JINBAICHENG METALHe mea kūʻai maikaʻi, ke kūʻai aku nei mākou a hoʻolako i kahi hui piha o API 5L Grade B Seamless Pipes a Welded Pipes, A106 Gr.ʻO nā paipu liʻiliʻi B me ka nui a me ke kumukūʻai haʻahaʻa, hoʻokipa e kelepona iā mākou.
