Navigating Submarine Pipeline Integrity: CRA Clad vs. Mechanically Lined Pipes (MLP)
ASTM A53 LSAW Steel Pipe is widely applied in oil, natural gas, steel structure, power plant, ship building, foundation and piling projects.
Steel Grade：
API 5L PSL1/PSL2 GR B , X42, X46, X52, X60, X65, X70
The full name of LSAW steel pipe is spiral seam submerged arc welded pipe, which is often used in urban infrastructure, chemical industry, oil and gas transportation and other fields that need long-distance transportation. LSAW steel pipe is well known in the modern industrial and global steel pipe market for its superior corrosion resistance, high strength and good weldability.
With over 40 years of excellence in the steel industry, JSFITTINGS stands as a premier manufacturer and global trader of high-quality ASTM A53 LSAW Steel Pipes. We specialize in providing heavy-duty, large-diameter Longitudinally Submerged Arc Welded (LSAW) pipes designed to meet the rigorous demands of construction, structural support, and low-pressure fluid transmission.
Leveraging four decades of production expertise, we ensure every pipe meets strict ASTM standards, offering superior durability and weldability for your critical projects.
We offer a comprehensive range of ASTM A53 Grade B pipes customized to your specific project requirements.
