1 Protection plates for underground networks

2 Specifications PROTECTION PLATES Protection plates for underground facilities 1 DESCRIPTION The OVERPIPE plate was developed in collaboration with the Research and Development Department of GDF Suez. Made of injected HDPE, they resist the assault of a 32ton shovel. They offer dedicated features : They have holes all over the surface of the plate in order to allow the flow of water and not disrupt the measurement of the cathodic protection. The holes are made by molding and not by later drilling which would weaken the plate Non-slip pins on both sides coming from the molding to facilitate handling and avoid slip and fall accidents Made in full body yellow (UV resistant) they are an effective warning signal and can be produced in different colours depending on the nature of the facilities. They have a customizable warning message, included in the mold The plates are assembled by superposition (10 cm overlap) or by juxtaposition and are linked by HDPE clips. APPLICATION The OVERPIPE plates are widely used to protect buried pipelines against third party damages. Light (30 to 40 kilograms depending on the model), they are particularly easy to install and can be easily removed to allow inspection or repair of the pipeline. The French Law gives the OVERPIPE plates a risk reduction coefficient of 0.01.
