polyethylene pipe roughness in belgium Despriction

Can hydrocarbons degrade polyethylene?Can hydrocarbons degrade polyethylene?Hydrocarbons do not degrade polyethylene but can diffuse through the wall of PE pipe in areas of gross contamination. Theexterior contact may affect sidewall fusions and or butt fusions; thus, after PE pipes have been exposed to grossly contaminated soils, mechanical connections may be preferred.

Unfortunately, commercial pipe roughness differs from sand grain roughness in both shape and arrangement. However, Colebrook carried out experiments on commercial pipes, expressing the commercial pipe roughness in terms of an equivalent sand grain roughness size (5).
