Geberit HDPE The Drainage System

Geberit HDPE pipes undergo a licensed annealing process in hot water to reduce inherent tensile stresses created during manufacture. This process ensures long-term joint integrity, as thermal expansion and reversion are reduced compared with untreated pipes. Impact resistance


Reroute the pipe in such a way that L is larger than U by about 10% Install an expansion loop Reroute the pipe at one end to allow the pipe to grow by “bending” a 90° leg Hot bolt the pipe so the expansion has occurred before the final pipe to equipment connection is made up.

Thermal expansion coefficient HDPE (PE 100) at -2.2°F

One value for thermal coefficient of expansion is considered adequate for the range of temperatures (including below zero) where HDPE is an appropriate material.

EX-TEND Expansion Joint for Water and Waste Water Pipelines

HDPE 0.000080 Concrete 0.0000055 The Change in length (∆L) due to thermal contraction/expansion is given by: ∆L = L (∆T)(C) Where: L = length of pipe (inches) ∆T = change in Temperature (degrees F) C = coefficient of thermal expansion Determine your expansion requirements Example: 1. Determine the Expansion Needed

Properties of HDPE pipe

HDPE has a lower modulus of elasticity and higher coefficient of thermal expansion than other pipe materials. These properties cause HDPE pipe to expand and contract much more from changes in temperature and/or pressure than other piping materials. Because of these and other properties, great care must be taken in choosing fittings and repair
