Our composite tubulars that we supply to the oil & gas industry are manufactured using fibre reinforced thermoplastics. Tapes of fibres impregnated with plastic are welded onto a liner of the same plastic compound. Completed by a coating, a fully bonded pipe structure is created, combining high pressure strength with tensile strength and spoolability. We call this the One Material Concept, all three elements (liner, composite layers and coating) are made of the same thermoplastic material.

By using melt-fusion instead of adhesives, a strong and stiff pipe wall is created that resists rapid gas decompression issues. The use of ductile plastics ensures that the pipe system is spoolable and features high impact resistance and residual strength.

This pipe system, unique in the world, has specific advantages that create a competitive advantage for our clients:

• The combination of pressure strength with tensile strength and spoolability allow for fast offshore deployment and cost-effective well intervention. On subsea well intervention, the running time is reduced with 75%.
• The low weight in combination with dynamical stability reduce the top tension loading on production vessels by 60% or more.
• The lack of corrosion and chemical resistance  properties offer unique possibilities for down hole static applications such as velocity strings.
• The solid wall supports the pipe in carrying the highest pressures and pressure fluctuations.
