API 5Lma keʻano laulā e pili ana i ka pipeline kila paipu (pipeline paipu) o ka hoʻokō ʻana o ke kūlana, pipelinepaipu kilame ka paipu kila seamless a me ka paipu kila welded ʻelua mau ʻano. I kēia manawa i loko o ka pipeline aila ua hoʻohana pinepine mākou i ka paipu kila welded ʻano paipu spiral submerged arc welded pipe (SSAW), paipu wili ʻia i hoʻopaʻa ʻia i loko o ka wai i hoʻopili pololei ʻia (LSAW), paipu kuʻihao kū'ē (ERW), paipu kila humuhumuʻO ka mea maʻamau, hoʻohana ʻia ka pipeline me ke anawaena ma lalo o 152mm.
Ua hōʻuluʻulu ʻia ka paipu kila maʻamau GB/T 9711-2011 no ka ʻōnaehana halihali pipeline ma ka ʻoihana aila a me ke kinoea e like me API 5L.
Kuhikuhi ʻo GB/T 9711-2011 i nā koi hana no nā paipu kila humuhumu ʻole a me nā paipu kila i hoʻopaʻa ʻia o ʻelua mau pae kikoʻī huahana (PSL1 a me PSL2) no nā ʻōnaehana halihali paipu ma ka ʻoihana aila a me ke kinoea. No laila, pili wale ke kūlana i nā paipu kila humuhumu ʻole a me nā paipu kila i hoʻopaʻa ʻia no ka halihali aila a me ke kinoea, a ʻaʻole pili i nā paipu hao i hoʻolei ʻia.
Nā Papa kila
ʻO nā pae kila o nā mea maka no nā paipu kila o kēia kūlana API 5L ʻo GR.B, X42, X46, X52, X56, X60, X70, X80, a pēlā aku. He ʻokoʻa nā pae kila o nā paipu kila, a he ʻokoʻa nō hoʻi nā koi no nā mea maka a me ka hana ʻana, akā ua kāohi pono ʻia nā mea like kalapona ma waena o nā pae kila like ʻole.
Nā kūlana maikaʻi
Ma ke kūlana paipu API 5L, ua māhele ʻia nā kūlana maikaʻi (a i ʻole nā koi) no ka paipu kila i PSL1 a me PSL2. ʻO PSL kahi pōkole no ka pae kikoʻī huahana.
Hāʻawi ʻo PSL1 i kahi pae maʻamau o nā koi maikaʻi o ka paipu; Hoʻohui ʻo PSL2 i nā koi mandatory no ka hoʻohui kemika, ka notched toughness, nā waiwai ikaika, a me nā NDE hou aʻe.
