PROTECTION OF UNDERGROUND TRANSMISSION NETWORKS

OVERPIPEUK PLATES

The OVERPIPE plates are especially designed to protect buried pipelines against third party damage and they offer a reliable, economic and environmentally friendly alternative to concrete slabs.

They were developed in collaboration with the Research and Development Department of ENGIE. They resist the assault of a 32-ton shovel and will therefore prevent the pipeline from any encroachment. They are also a very efficient warning signal.

They are validated by the French governmental regulatory (GESIP) as a mechanical protection offering a risk reduction factor of 0.01.

Lightweight (30 to 40 kg depending on the model), they are particularly easy to install and can be easily removed to allow inspection or repair of the pipeline.

PLATE INFORMATION

The OVERPIPE plates are made of injected HDPE. They have dedicated features such as:

Holes all over the surface (but less than 1% of the total surface) to allow the flow of water to go through and not disrupt the measurement of the cathodic protection. The holes and not by later drilling which would weaken the plate.
Beveled edges and non-slip pins on both sides to facilitate handling and avoid slip and fall accidents.
Full body yellow color (UV resistant) as an effective warning signal different colors possible depending on the nature of the networks).
Fully customizable embossed warning message.

The OVERPIPE plates come in various dimensions to fit with the pipe diameter and to grant an extra width on the sides. The plates are assembled by superposition (10 cm overlap) or by juxtaposition and are linked by HDPE clips and caps.
