Top 10 Companies in the Global Large-diameter Longitudinal Submerged Arc Welded Pipe Market (2026): Market Leaders Powering Global Infrastructure

MARKET INSIGHTS

Global large-diameter longitudinal submerged arc welded (LSAW) pipe market size was valued at USD 8.42 billion in 2024. The market is projected to grow from USD 8.97 billion in 2025 to USD 13.76 billion by 2032, exhibiting a CAGR of 5.8% during the forecast period.

Large-diameter LSAW pipes are high‑strength steel pipes manufactured through the submerged arc welding process, primarily used for transporting oil, gas, and other fluids over long distances. These pipes typically range from 16 inches to 60 inches in diameter and are crucial for pipeline infrastructure projects. The manufacturing processes include UOE (U‑ing, O‑ing, and expansion) and JCOE (J‑ing, C‑ing, and O‑ing followed by expansion) forming methods.

The market growth is driven by increasing energy demand, expansion of oil & gas pipeline networks, and growing infrastructure investments globally. However, fluctuating raw material prices and environmental concerns pose challenges. Recent developments include capacity expansions by key players like Nippon Steel Corporation and JFE Steel Corporation to meet rising demand from energy and construction sectors.
