19/4/2006· I was planning on using HDPE pipe for GW collection. The EPA''s Chemical Compatibility Table says that HDPE is "Unsatisfactory" when Benzene is present. Although I''ve been told that Benzene is the most common driver for gas station site remediation, and that HDPE is fairly common in that arena.
Poly (HDPE) pipe lengths vary according to size, however, generally sizes up to 110mm are available in 6 metre straight lengths or 50m, 100m or 150m pipe coils. Sizes 125mm and above are generally available in 12 metre lengths, which offers huge cost savings by reducing nuers of onsite joins.
Figure 1 Stress rupture curves for five HDPE geomeranes (Hsuan et al. 1992) It is frequently stated by some in the geomerane and gas pipe industries (Peggs (2003)), Thomas (2002) Brown (1993)) that the only meaningful parameter that requiresHDPE is
