Plastic Pipes Conference Association # 2021 Amsterdam

Donald McGriff, White Jee

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.

2018 Las-Vegas : New crosslinked (PEX) pipes from sustainable resources

Author(s) : Jacob John, Andrew J. Ortquist, Mats Thunwall, Patrik A. Roseen

This study investigates production of crosslinked polyethylene (PEX) pipes using a resin obtained from a renewable resource via twin-screw extruder technology. PEX pipes were extruded using petroleum-based and renewable high-density polyethylene (HDPE) for comparison. Testing using relevant ASTM standards on the new...

2018 Las-Vegas : Preparation and studying of thermoplastic cross-linked polyethylene

Author(s) : Cheng Zhi, Mingyuan Hu, Kaige Duan, Chaoxi Zhou, Dongming Yu

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...

2016 Berlin : Electrofusion joining performance of very large pressure pipes produced with MFR5<0.2 g/10min PE100

Author(s) : Predrag Micic, Cliff Mure

An extensive investigation was conducted into the electrofusion compatibility of pipes produced using a PE100 resin with an MFR5 value below 0.2 g/10min. The electrofusion (EF) joining program included pipes up to 800 mm in diameter and the use of electrofusion couplers and saddle type fittings as well as varying...

2016 Berlin : Expanding the application range of high density polyethylene for use as an inner-liner material in reinforced thermoplastic pipe and steel pipe

Author(s) : Johannes de Bruin, Dr. Bert Dalmolen, Albo van Hateren

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...

2014 Chicago : Selection of a Load Level for Testing to Determine the Creep Modulus of Thermoplastic Corrugated Wall Pipe for AASHTO LRFD Thermoplastic Pipe Design

Author(s) : Jesse L. Beaver

The design of corrugated wall thermoplastic pipes requires evaluation of loads applied to the pipe upon installation and those applied to the pipe throughout its service life. For loadings that are characterized as dead loads, the thermoplastic pipe will experience creep and/or relaxation for the duration of the...
