LINER FoR Oil aND GAS PIPELINES
THE ALTERNATIVE TO CRA AND CLAD PIPES
Thanks to its mechanical resistance after saturation in crude oil, even at high temperatures, the VESTAMID® NRG liner allows the construction of compression-resistant liners e.g. for stabilized crude oil applications.
For water injection pipelines on the sea bed, the inserting of a thermoplastic liner is a method that has been established for more than 15 years. Pipeline operators all over the world are convinced of the clear cost advantages (CAPEX and OPEX). But the liner used in this technology is of polyethylene, which is unsuitable for oil transport lines.Polyamide 12 does have the property profile required for a liner material, however, and is therefore a genuine alternative to stainless steel based systems. This evolution of an established technology, while only a small step in itself, offers potential for enormous cost savings.
The key advantages of the VESTAMID® NRG liner are:
Improved availability as CRA and cladded solutions
Clear Capex savings compared to CRA design
Clear Opex savings compared to designs with corrosion allowance
No anti-corrosion treatment required
Working temperatures up to 80 °C (100 °C without hydrolysis
Reliability due to dimensional stability while in use
Suitable for H2S, methanol and crude oil
Reliability due to specially adapted liner design which is suitable for process fluids
VESTAKEEP® PEEK is Suitable for use as a borehole liner for working temperatures exceeding 120 °C
Thermoplastic liners are increasingly applicable for wellbore casing strings. In response to the increasing demands imposed by rising working temperatures and pressures, the VESTAKEEP® PEEK polymer with high temperature resistance alongside excellent impact strength and high mechanical strength represents an optimal solution.
15 % enhanced impact strength
50 % higher tensile modulus at 150 °C than other PEEK materialsVESTAKEEP®
