API linijos vamzdis‌ yra dujotiekio medžiaga, naudojama naftos, gamtinių dujų ir vandens gabenimui iš ekstrahavimo vietų į perdirbimo įrenginius. Jis pirmiausia suskirstytas į kategorijas į ‌Besiūliai vamzdžiai‌ ir ‌suvirinti vamzdžiai‌. Taikomi standartai apima ‌Api spec 5l‌ ir ‌GB/T 9711‌, su medžiagų rūšimis nuo ‌L245‌ iki ‌X100‌ (pvz., X42, x52 ir kt.), Kad atitiktų skirtingus stiprumo reikalavimus.
