Design requirements for nonmetallic piping systems are significantly different from those applicable to piping made of steel and other metals, and the development of rules for nonmetallic materials requires a unique set of expertise. While other piping standards have tried to address the use of nonmetallic materials in industrial piping, they do not provide adequate requirements to cover the service limitations, design, materials, fabrication, installation, fusing or joining, and quality control which are unique to nonmetallic piping systems. To address this gap, ASME assembled the Committee on Nonmetallic Pressure Piping Systems (NPPS) in 2011 to develop standard rules for the construction of nonmetallic pressure piping systems. Over the last 7 years, the NPPS Committee has developed three new standards which are scheduled to be published in 2018: ASME NM.1 Standard on Thermoplastic Piping, ASME NM.2 Standard on Glass Fiber Reinforced Thermosetting Resin Piping, and ASME NM.3 Standard on Nonmetallic Materials. These standards cover the design, manufacture, fabrication, installation, examination, testing, and inspection of thermoplastic and glass fiber reinforced thermosetting resin piping systems suitable for pressure applications. They will also cover specifications for nonmetallic materials for piping components including material design values and limits on the use of nonmetallic materials.
