ʻO ka ʻōlelo maʻamau, pili ka API 5L i ka paipu laina API 5L, aia ma waho o ka ʻāina ka aila, ke kinoea, ka wai, lawe ʻia e ka pipeline i ka paipu aila a me nā hui ʻoihana kinoea.

e like me ke kaʻina hana a me ka pua o ka paipu i hoʻohana ʻia i nā ʻano like ʻole, hiki ke hoʻokaʻawale ʻia ʻo api 5l i api 5l seamless steel paipu a me api welded kila paipu, i waena o ka nui hoʻohana o welded kila paipu oi ma mua o seamless kila paipu.

Ka pae paipu laina a me nā mea kemika

Hiki ke hoʻokaʻawale ʻia ʻo API 5L i API 5L PSL 1 a me API 5L PSL 2, me ka API 5L PSL 1 pae a me nā waeʻano: A, B, x42, x46, x52, x56, x60, x65, x70, API 5L PSL 2 pae a ʻo ka māhele ʻo B, x42, x46, x52, x56, x60, x65, xx70, x80.ʻoi aku ka kiʻekiʻe o ka pae ʻoi aku ka ikaika o nā waiwai mechanical.

Hoʻohana: hoʻohana ʻia no ka ʻoihana aila a me ke kinoea, kinoea, wai, lawe ʻaila.
