Natural Oil And Gas API 5L Oil Pipeline

Ang API 5L pipe ay carbon steel pipe na ginagamit para sa oil at gas transmissions, kabilang dito ang mga pipe na ginawa sa seamless at welded (RW, SAW). Sinasaklaw ng mga materyales ang API 5L Grade B, X42, X46, X52, X56, X60, X65, X70, X80 PSL1 at PSL2 onshore, offshore at sour services. API 5L ang pamantayan ng pagpapatupad ng steel pipe para sa pipeline na sistema ng transportasyon at detalye para sa line pipe.
