How does HDPE pipe compare to concrete and metal pipe?
HDPE material costs are generally equal to or less than comparative sizes of concrete and metal pipes. Due to the low Manning’s ‘n’ value of dual wall pipe, HDPE pipes are generally one diameter smaller than metal pipes for equivalent flow characteristics, making HDPE even more cost effective. The inert nature of HDPE and its high abrasion-resistance allow HDPE pipe to be used in environments when concrete and metal require thicker walls or additional coatings to obtain the required performance. HDPE is manufactured in longer lengths (20′) and is significantly lighter than concrete pipe, which equates to faster, safer installation. Finally, Timewell MaXflo pipe offers a bell and spigot coupler that allows faster installations than metal pipe. Therefore, considering the competitive cost of MaXflo pipe and the savings due to higher performance and faster, safer installations, Timewell MaXflo pipe is logical alternative to providing cost effective storm drain pipe applications.
