A Value Chain Analysis of Non-Metallic Reinforced Thermoplastic Pipe (RTP)

Abstract

Abstract The objective of the paper is to explore the benefits and reliability of reinforced thermoplastic pipe (RTP). This will be achieved by focusing on the following topics: Installation and operation benefits of non-metallic pipes compared to steel line pipe Overview of the importance of API qualification testing and the API Monogram in relation to API 15S 3rd edition (released in Q2 2022) Highlighting the significance of API Specification Q1 in the production of quality products Understanding the latest advancements in improving the quality/integrity of installations The paper will guide the audience through the design, manufacturing, and installation of RTP, in order to demonstrate the significant performance and installation benefits of the products. To highlight the robust design, the rigorous requirements of API Specification 15S and API Specification Q1 will be examined, and the relevance and importance of several key elements will be discussed. Several defining elements of the standard will be explored in detail to demonstrate the requirements behind designing a reliable spoolable composite product. Installation quality is a significant factor in composite pipe performance, and the paper will also evaluate and highlight key technologies that can help improve installations. RTP can be designed, constructed, and installed to be a world class product. This paper will demonstrate the test requirements and results required by API Specification 15S to be such a product. Observations regarding the requirements for product families and product family representatives will be covered including test results and observations for several key tests, including, but not limited to, long term hydrostatic testing, elevated temperature testing, and cyclic regression testing. Non-metallic products have proven to be effective in lowering operating costs by reducing corrosion-related pipe failures when installed correctly and according to the manufacturer's recommendations. This paper will study tools that can be used to guide installations as well as document and track the installation process. The resulting improvements can be studied in the failure rates. After reviewing the paper, the reader will have a thorough understanding of how to evaluate and install spoolable composite line pipe in a variety of services and locations.
