RTP, reinforced thermoplastic pipe, refers to oil and gas pipelines combined with a fiber reinforcement of thermoplastic composites. The reinforcement can be PP, PE, PA, PVDF, HDPE, etc. with different fiber types including long fiber, short fiber or continuous fiber.
RTP pipes are available in coils up to 400 m (1,312 ft) in length. They are easy to install and particularly useful in a variety of on- and off-shore applications, including high-pressure water injection pipelines, water transport solutions, effluent water disposal, oil and gas flowlines, oil and gas gathering lines and gas pipeline.
Primarily, such kind of pipes provides benefits to applications where steel may rupture due to corrosion (RTP is corrosion free) and installation time is an issue.
RTP Pipe Materials in TOPOLO
Due to the advantages of reinforced thermoplastic pipes, more and more major oil and gas companies and operators started to replace their steel pipelines with this new technology. They use different ways to reinforce their pipe products. In TOPOLO, you can see the HDPE pipes reinforced by our continuous glass fiber composites in three layers. The length can be more than 1000m, the width is between 30mm and 300mm, and the thickness can be as thin as 0.2mm.
The most important parameter of pipes in heavy industries is tensile strength. For instance, to meet the demand for oil and gas pipes in deep sea or undergrounds, the strength of the reinforcement should be at least 800Mpa. For this, the fiber content in HDPE should be around 60-65%. TOPOLO can even produce such reinforced materials containing 70% glass fiber, with the tensile strength even higher (900Mpa).
RTP Pipe Application
Typical application areas of continuous fiber reinforced thermoplastic pipes winded with TOPOLO T-UD series CFRT tapes can be found in oil and gas industries including:
High-pressure water injection pipelines
Water transport and distribution
Temporary surface lines
Oil and gas flow and gathering lines
(Domestic) Gas pipelines
