Thermal Insulation

Multilayer polpropylene coating for onshore and offshore line pipe applications.

Our coating solutions protect and insulate pipes used in offshore and onshore projects in order to guarantee flow assurance.

 

Thermal coating solutions

Tenaris offers a complete range of thermal coating solutions in alliance with internatinal coating companies. These solutions protect and insulate pipe used in offshore projects in order to guarantee flow assurance. We can provide:

WET INSULATION

  • Glass syntactic polyurethane
  • Polypropylene foam syntactic
  • Multi-layer polypropylene

PIPE-IN-PIPE INSULATION

Glass syntactic polyurethane pipe insulation

We offer syntactic polyurethane thermal insulation solutions for flow assurance in applications involving offshore shallow water pipelines. This option can be used in operating temperatures of between -35ºC and 115ºC.

Polypropylene foam syntactic insulation

To guarantee offshore flow assurance, we offer a polypropylene foam syntactic insulation coating system recommended for operating temperatures ranging from -35ºC to 155ºC and water depths of a maximum 2,800 meters.

Multi-layer polypropylene pipe insulation

We provide a multi-layer thermal insulation application process that results in a combination of anti-corrosion and thermal insulating materials applied to steel pipe in multiple layers. The system is similar to a conventional three-layer anti-corrosion system; however, additional layers of solid, foam or syntactic polypropylene are used depending on the water depth.

The multi-layer polypropylene is recommended for operating temperatures of up to 140ºC and water depths greater than 3,000 meters. Meanwhile, the multi-layer polypropylene foam works in operating temperatures ranging from -20ºC to 140ºC and water depths up to 600 meters.

Pipe-in-pipe insulation

Our offer includes coating for pipe-in-pipe systems, which include an outer pipe able to withstand water pressure and prevent water penetration, and an inner pipe which conducts the production fluids. The thermal insulation material is placed between the production flowline and the carrier pipe.

We supply the outer pipe, inner pipe and high-efficiency insulation system to optimize flow assurance in the most complex scenarios.
