ASTM Releases Its First Specification for Flexible Pre-Insulated Piping

ASTM Committee F17 on Plastic Pipe Systems approved new Standard Specification F 2165 for Flexible Pre-Insulated Piping on January 10. Piping-industry members in the F17.11 Composite Subcommittee developed the specification to describe flexible pre-insulated piping systems used in hot and chilled water distribution.

F 2165 describes how the carrier pipe, factory-applied insulation and outer jacket of pre- insulated piping systems function as a system. “Although the components are all manufactured to individual standards, there is a need to understand how the individual components work together as a system,” said Jim Clauss, a technical services manager for Ecoflex, a piping-system manufacturer in Wilmington, Ill.

Clauss, who chaired the development of F 2165, said the standard will help users to measure material quality and understand their properties.

“A major feature of this standard is a test procedure to define the actual flexibility of the pre-insulated piping system,” he explained. “The defined flexibility can be used by installers to understand the characteristics and workability of the piping system. Although this type of piping system is widely used in Europe, it is relatively new in the U.S. market.”

Eight stakeholders developed the specification: a fitting manufacturer, two pipe manufacturers, an independent testing lab, a consultant, two pipe-system manufacturers, a pipe-system supplier, and a piping trade-group representative. “It has been extremely gratifying to work with the professionals that participated in the development of the first ASTM standard of its kind,” Clauss said.

The subcommittee is drafting a standard for other pre-insulated piping systems. For more information, contact Jim Clauss, Ecoflex, Wilmington, Ill. (phone: 815/476-0300).

Committee F17 meets April 15-18 in Pittsburgh and Nov. 4-7 in Miami Beach, Fla. For meeting or membership details, contact Pat Picariello, manager, ASTM Technical Committee Operations (phone: 610/832-9720). //
