Alternative installation methods are preferably used for overland sections, as the advantages of these methods are particularly significant for long trench lengths with few connections. Low-digging methods include in particular ploughing and milling. Both methods are extremely economical due to their high laying performance. GEROfit® pressure pipes with additive protective coating according to PAS 1075, Type 3 meet the requirements for both scratch resistance and stress cracking resistance.
PloughingIn the ploughing method, the soil is displaced by a plough blade and the pipeline is placed on the bottom of the soil.
MillingIn the milling process, a pipe trench is cut into the subsoil by machine and the pipeline is laid on the bottom of the trench.
