API SPEC 5L-2018 (line pipe specification), i hōʻuluʻulu a hoʻopuka ʻia e ka American Petroleum Institute, hoʻohana mau ʻia ma ka honua holoʻokoʻa.

Paipu laina: loaʻa nā paipu ʻole a welded. ʻO nā wēlau paipu he mau wēlau palahalaha, nā welau wili a me nā kumu kumu; ʻO nā ala pili ka hoʻopau ʻana i ka welding, ka hoʻohui ʻana, ka pilina socket, etc. ʻO nā mea nui ʻo GR.B, X42, X52. X56, X65, X70 a me nā māka kila ʻē aʻe.

ʻO API SPEC5CT-2012 (Casing and Tubing Specification) i hōʻuluʻulu ʻia a hoʻopuka ʻia e ka American Petroleum Institute (American Petreleum Instiute, i kapa ʻia ʻo "API") a hoʻohana ʻia ma nā wahi āpau o ka honua.

i:

Casing: He paipu e hohola ana mai ka ʻili o ka honua a hiki i ka pūnāwai a lilo ia i mea hoʻopaʻa pā luawai. Hoʻopili ʻia nā paipu e nā hui. ʻO nā mea nui he mau kila kila e like me J55, N80, a me P110, a me nā māka kila e like me C90 a me T95 i kū i ka hydrogen sulfide corrosion. Hiki ke wiliwili ʻia kona pae kila haʻahaʻa (J55, N80).

Paipu: He paipu i hoʻokomo ʻia i loko o ka pahu mai ka ʻili honua a hiki i ka ʻaila ʻaila, a ua hoʻopili ʻia nā paipu e nā hui ʻana a i ʻole ka hui pū ʻana. ʻO kāna hana ʻo ia ka ʻae ʻana i ka ʻāpana pumping e lawe i ka ʻaila mai ka papa ʻaila a i ka lepo ma o ka paipu. ʻO nā mea nui nā māka kila e like me J55, N80, P110, a me C90, T95 i kū i ka hydrogen sulfide corrosion.
