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 desulphurizationʻO 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. Hōʻike mākou i ka nui o 0.007%.
API 5L Pōmaikaʻi a me nā hoʻohana ʻana i ke kinoea, ka wai a me ka ʻaila - makemake ʻia i nā paipu lōʻihi ma muli o ke kumukūʻai.ʻO ka American Petroleum Institute specification API 5L e kamaʻilio i ka paipu laina kila maʻemaʻe a i hoʻopaʻa ʻia no nā ʻōnaehana kaʻa paipu i loko o nā ʻoihana ʻaila a me nā kinoea maoli. He kūpono ka API 5L no ka lawe ʻana i ke kinoea, ka wai, a me ka ʻaila.
ʻO nā kikoʻī no ka API 5L e pili ana i ka International Organization for Standardization ISO 3183, ka hoʻonohonoho ʻana i nā ʻōnaehana halihali pipeline i loko o nā mea waiwai, nā mea hana a me nā hale o waho no ke kinoea maoli, ka ʻaila, a me nā ʻoihana petrochemical. I ke kākau ʻana i nā maʻamau, ua ʻike ke komite ʻenehana aia ʻelua mau pae kikoʻī o nā huahana kumu (PSL) o nā koi ʻenehana a no laila ua kūkulu ʻia ʻo PSL 1 a me PSL 2. He kūlana maʻamau ka PSL 1 no ka paipu laina kahi i loaʻa ai i ka PSL 2 nā mea kemika hou aʻe. , a me nā koi hoʻāʻo.
ʻO nā māka i uhi ʻia e kēia kikoʻī ʻo A25, A, B a me "X" Papa X42, X46, X52, X56, X60, X65, X70, a me X80. ʻO ka helu helu ʻelua ma hope o ka "X" e hōʻike ana i ka ikaika hua liʻiliʻi (ma 000's psi) o ka paipu i hana ʻia i kēia papa.
