ASTM A671 longitudinal submerged arc welded (LSAW) pipes are widely used as pipeline materials in industries such as oil, gas, chemical, and power generation, offering excellent mechanical properties and corrosion resistance. These steel pipes are manufactured using electric fusion welding (EFW) technology and comply with the ASTM A671 standard, making them suitable for low-temperature and high-pressure environments.
