PPI responds to HDPE standard updates
The Plastics Pipe Institute (PPI) has commented on recent updates to the ASTM F2160 standard for high density polyethylene (HDPE) conduit.
PPI is the major North American trade association representing all segments of the plastic pipe industry.
In a statement, it said that among other changes, the scope of the standard has now been expanded to include more standard dimension ratio (SDR) sizes and applications of HDPE conduit.
Specification for Solid Wall High Density Polyethylene (HDPE) Conduit Based on Controlled Outside Diameter (OD) is applicable to coilable HDPE conduit, duct and innerduct for the protection of fiber-optic and power cables.
It applies to HDPE conduit in IPS types SDR 9, SDR 11, SDR 13.5, DR 15.5, Schedule 40, Schedule 80, “true-sized” and SIDR dimensions.
Typical applications include telecom, highway lighting, supervisory control and data acquisition systems command and control, intelligent transportation systems and underground utilities, including wind power and solar energy farms.
“This is a significant update to the controlling ASTM standard used for HDPE conduit,” said PPI Director of Engineering – Power and Communications Division (PCD) Lance MacNevin P. Eng.
“Originally published in 2001, the effort to make these December 2016 revisions to F2160 was led by PPI’s PCD.
“This resulted in significant improvements to the standard such as the addition of SDR sizes and new applications, eleven dimensional tables are now consolidated into four for ease of use, the cell classification descriptions now harmonised with ASTM D3350, improved slow crack growth resistance is required and there is also the addition of pipe stiffness, compression and recovery requirements.”
“Today’s conduit must be able to stand up to aggressive installation methods such as horizontal directional drilling and provide years of underground life.
“Working with ASTM is one part of our division’s goal to establish consistent, high-quality performance of polyethylene pipe for all these growing conduit applications.”
