Export Lines-Flowlines

Export Lines

Our export lines and flowlines are developed with the most advanced, extreme, heavy-wall tubular products available in the industry.

High quality line pipe for Export Lines and Flowlines

Export lines, sometimes called pipelines, transport processed or non-processed oil or gas fluids to the shore.

Tenaris with its strong industrial system has the capability to supply a complete range of flowlines and export lines in steel grades up to X70 sour service resistant and 100 ksi yield strength non-sour service. We offer both seamless and welded pipe for flowline and export line applications.

Our export lines and flowlines are developed with the most advanced, extreme heavy-wall tubular products available in the industry. These products either meet or exceed the industry’s most demanding fracture toughness and mechanical properties requirements in terms of toughness, corrosion resistance, dimensional tolerances and weldability (in our own welding laboratory).

We supply export lines and flowlines that can withstand stringent deep-sea environments (high pressure and temperature and/or corrosion resistance), as well as demanding installation methods, such as J-Lay and reeling, with our world class support network of R&D Centers committed to developing new products and to constantly seeking improvements in products, steels, production processes and services.

The specific environment, reservoir and fluid conditions as well as the use of longer tie-backs combined with high pressure and a wide range of working temperatures, mean that the need to guarantee flow assurance has become one of the most critical issues.

We offer a wide range of tubular and coating solutions, which help in the thermal management of the pipelines, including:

  • Dry insulation: pipe-in-pipe systems (outer and inner pipe)
  • Wet insulation: a complete range of thermal insulation coatings solutions that protect and insulate pipe used in offshore projects
  • Active heating: bundles


We work to support industry needs by providing services for the most demanding environments:
