SACRIFICAL SPACER RINGS

Among the range of Polyurethanes manufactured from Company Services Swiss SA Group, one solution is specifically developed to easily build up sacrificial spacer rings to be moulded onto a 3LPE or 3LPP pipe in order to protect it from abrasion / wear.

One application which is ongoing since many years is the protection of the parent coating of O&G pipelines in the concrete microtunnels sections, thus ensuring easy pulling of the pipes in the microtunnel without damaging the parent coating.
