API 5L X52 TUBE
API 5L X52 tube is a high-strength carbon steel line pipe widely used for the transportation
of oil, gas, water, and other fluids under high-pressure conditions. Also known as L360
tube,
it offers a minimum yield strength of 52 Ksi (360 MPa), making it suitable for demanding
pipeline
and structural applications. API 5L X52 tubes are manufactured in accordance with API 5L and
ISO 3183 standards, ensuring excellent weldability, toughness, and long-term performance.
These tubes are extensively used in both onshore and offshore pipeline systems, including
sour
service environments where high resistance to corrosion and mechanical stress is required.
API 5L X52 PSL2 tubes are commonly supplied with surface finishes such as black paint,
varnish,
oil coating, or anti-corrosion coatings to enhance durability and service life.
API 5L X52 tubes are available in a wide range of sizes, wall thicknesses, and schedules to
meet
diverse project requirements. They are widely used in oil & gas transmission pipelines,
water
pipelines, power plants, construction, and general engineering applications due to their
higher
strength and reliable mechanical properties.
Revinox is a trusted supplier of API 5L X52 tubes, delivering products that
comply
with international quality standards and project-specific requirements. These tubes are
ideal
for applications demanding strength, dimensional accuracy, and consistent performance.
