DUCT BLINDS
Duct blinds are used to seal the ends of steel or concrete sleeve for a pipeline in order to avoid any earth mud and water accumulation between sleeve and pipeline.
Duct blinds are particularly recommended at road, path and railway crossings and the like.
We offer two types of duct blinds:
- Blinds molded by seamless vulcanization.
- Blinds fabricated from a rubber sheet.

ON type blinds
ON type blinds are used for fixed pipeline and sleeve diameters and they are available in variants with 1, 2, or 3 folds allowing the compensation of the difference in pipeline/sleeve colinearity.

ONV type blinds
ONV type blinds are used for variable pipeline diameters and invariable sleeve diameters. They have a conical shape to match the pipeline diameter after being cut.
The blind ensures an optimal sealing of the annular space between pipeline and sleeve by means of two O-rings.
