Rohrlining

Rohrlining is a specialized process used to restore and reinforce the interior surfaces of pipelines, particularly those that are aging, corroded, or damaged. This technique involves lining the existing pipe with a protective and durable material to extend its operational lifespan without the need for complete replacement.

The primary methods of Rohrlining include cured-in-place pipe (CIPP) lining, slip lining, and spray lining. CIPP involves inserting a flexible liner soaked with resin into the damaged pipe, which hardens in place to form a new pipe within the old one. Slip lining uses a smaller diameter pipe inserted into the existing pipeline and then grouted or sealed in position. Spray lining applies a coating directly onto the interior surface to seal leaks, prevent corrosion, and provide a smooth flow surface.

Rohrlining offers several advantages, including reduced excavation costs, minimized service disruption, and the ability to rehabilitate pipelines located in difficult-to-access areas. It is commonly employed in municipal water and sewer systems, industrial pipelines, and oil and gas infrastructure.

The selection of a specific lining method depends on factors such as pipe material, diameter, condition, and the nature of the damage. Proper evaluation and planning are essential to ensure the long-term effectiveness of the lining and to maintain system integrity.

Overall, Rohrlining is recognized as an efficient, cost-effective, and environmentally friendly solution for pipeline rehabilitation, contributing to infrastructure sustainability and safety.
