LSAW Pipes

LSAW pipes (Longitudinal Submerged Arc Welded) pipes are high-strength welded steel pipes manufactured by bending and welding steel plates longitudinally. These pipes are designed for critical high-pressure applications and large-diameter pipeline systems that demand structural integrity, dimensional precision, and superior weld quality. LSAW pipes are most commonly used in oil & gas transmission, offshore pipeline projects, water supply lines, structural piling, and infrastructure development.

LSAW pipes are preferred for their straight seam weld, thicker wall capabilities, and high reliability under demanding mechanical and environmental conditions. Compared to ERW and SSAW pipes, LSAW pipes are ideal for longer pipelines where welding consistency, pressure tolerance, and roundness are vital.

At Middle East Piping, we supply LSAW pipes in accordance with leading international standards such as API 5L (PSL1 & PSL2), EN 10219, ASTM A672, and ISO 3183, available in grades like X42 to X80, as well as standard carbon steel grades (S235, S355, etc.). These pipes are available in OD sizes from 16” to 60” and thicknesses up to 50mm, with both beveled and plain ends, and anti-corrosion coatings including 3LPE, FBE, and galvanized options. click here

All LSAW pipes are hydrotested and inspected using ultrasonic and radiographic testing (UT/RT), ensuring weld seam and full-body integrity. We can supply mill test certificates in compliance with EN 10204 3.1 / 3.2, with full traceability and third-party inspections on request. click here

LSAW pipes are a robust, long-life solution for heavy-duty and high-pressure pipeline applications across Saudi Arabia, UAE, Oman, Bahrain, and Qatar.
