OPTIMAL PIPELINE MANAGEMENT

Asbestos cemented
pipelines

The formerly widely used cementitious material is still present in the underground. The aim of risk based pipeline management is to identify the aging of cementitious pipes and use the information to support future based management.

By connecting fundamental underlying failure mechanisms, manifestations and its inspections to the experience of the client/environment/HDM, all conditions are present to judge a specific pipeline or to develop a more generic assessment model for multiple pipelines within in one area.



Why to choose HDM Pipelines?


We have the necessary background information, practical knowledge and a range of (test) data to support you.

Do you feel the need to discuss the cementitious pipelines in your area and how to create a reliable overview? Do not hesitate to contact us.



In practice


The above was the situation for HHNK (see also project ‘Beoordelingsmodel AC persleidingen‘ – in Dutch). The DN900 pipeline Hoorn was moved and provided the ideal opportunity to inspect and test the pipeline.

HHNK put in a lot of effort to get the necessary information. Besides, external knowledge sources were consulted to collect as much comparable research as possible. This was combined with Thymolphthalein tests, results of destructive testing and field tests. We developed a mathematical assessment model, in which the original design was compared to the current acceptable standards.

On the basis of this approach it was possible to develop a generic assessment model for HHNK. With this model we are able to do an substantiated check of the remaining AC fields.

The model provides HHNK the necessary insight into:

  • Remaining safety in the pipeline;
  • Influence of individual factors (e.g. What will vacuum pressure cause in this pipeline?).

This model includes i.a. the essential behaviour of the material, environmental factors and (future) usage, and shows the impact of specific changes in a comprehensible manner.
