In May of 2019, ASME published its first consolidated set of nonmetallic pressure piping standards consisting of:
NM.1, Standard on Thermoplastic Piping Systems
NM.2, Standard on Glass-Fiber-Reinforced Thermosetting Resin Piping Systems
NM.3, Standard on Nonmetallic Materials This presentation is part of an effort by ASME to inform its membership and those in the industry that are potential users of nonmetallic piping subject to ASME Codes and Standards. It provides background on the development, general overview on the contents of the standards relating to thermoplastic pipe, and the challenges and future developments as additional nonmetallic materials are included into these standards. It will educate the participants on this new consolidated resource for engineers and designers and serve as an invitation to industry leaders for additional knowledge and expertise as this evolving resource will grow to comprise additional nonmetallic materials and piping systems, including new materials when they become available.

One solution in development for managing runoff water is the buried stormwater drainage retention tank or “crate”. The crate is typically a rectangular box structure made of thermoplastic components (flat panels and columns) assembled in a modular form. The function of the top panel is to transfer the load to the...

Reinforced thermoplastic pipes (RTPs) are multilayer structured pipes reinforced with high-strength materials such as fibers (glass, aramid, or carbon fibers). RTPs are used to transport highly corrosive mediums at elevated pressures and temperatures. An example of that is the use of RTP in the Oil & Gas industry to...

The PE properties are obviously improved by crosslinking modified to TPEX, which can approach to that of PEX, while still remaining thermoplastic. It can be processed by the common forming method of thermoplastic; the products can be hot-melted and the scrap can be processed to be reused. The two-layer structure...

Normal High Density Polyethylene (HDPE) is commonly used as the fluid contacting element, or the “inner-liner”, in Reinforced Thermoplastic Pipes (RTP) and steel pipes up to 65 ºC. Through a modification of the HDPE polymer matrix, by adding nanoparticles, the E-modulus can be increased. Research shows that...
