API 5L, a'i enw llawn ywManyleb Sefydliad Petrolewm America 5L, yn fanyleb safonol ar gyfer tiwbiau dur pibell llinell yn y diwydiant petrolewm a nwy naturiol, a sefydlwyd gan Sefydliad Petroliwm America (API). Ers ei chyhoeddi am y tro cyntaf ym 1926, mae'r safon hon wedi cael ei hadolygu a'i gwella sawl gwaith, gan ddod yn un o safonau awdurdodol a gydnabyddir yn fyd-eang. Mae API 5L nid yn unig yn pennu gofynion sylfaenol megis dimensiynau, priodweddau deunyddiau, perfformiad mecanyddol, cyfansoddiad cemegol, profion nad ydynt yn ddinistriol, a phrofion hydrostatig ar gyfer pibellau dur ond mae hefyd yn eu categoreiddio i raddau lluosog (ee, X42, X52, X60, X65 hyd at X120) yn seiliedig ar wahanol amgylcheddau gweithredu ac amodau i gwrdd â phwysau a gofynion tymheredd amrywiol ar gyfer cludo.
