In today’s oil and gas industry, everyone is looking for ways to reduce costs. The selection of materials for oil and gas pipelines to transport the hydrocarbon will affect the operation cost, lead time, compliance, installation convenience, maintenance cost, total cost of ownership, etc. Therefore, in the past decade, a kind of innovative flexible composite pipe systems has been developed and applied to replace the traditional steel pipeline. RTP (Reinforced Thermoplastic Pipe) is a multi-layers composite pipe, which has a thermoplastic liner, a reinforcing layer and a thermoplastic jacket. The potential offered by this type of product for a wide range of applications in the oil and gas industries has been recognized in recent years, such like offshore, onshore and hydrogen gas transportation. The steel pipe can match the requirements of pressure and temperature, but it is expensive and rigid pipeline. The friction coefficient is large when the diameter is small, which may hinder the flow performance. Compared with steel pipes and other types of rigid pipes, RTP composite pipes have the following unique advantages: Composition structure pipe offers RTP the same strength as steel pipe. The use of different polymers and reinforced materials can provide RTP enhanced properties to meet the challenges of potential applications. The choice of non-metallic reinforcement can give RTP perfect corrosion resistance ability, thus deliver greater durability of pipeline and reduce the total cost of ownership. RTP offers a lower friction coefficient that would increase flow performance.
