A review on the durability of pvc sewer pipes

Towards that direction, the main factors and mechanisms that affect a PVC pipe’s lifetime are discussed in this article, along with the current lifetime prediction methods and their limitations. The review of relevant case studies indicates that material degradation, if any, occurs slowly. . A necessary condition for achieving this is comprehensive understanding of the mechanisms that affect a PVC pipe’s lifetime, their combined effects and eventually their results, which are the defects found in practice. An overview of these mechanisms and their origins is included in this article. Lifetime prediction methods for UPVC pipes are also utilised to describe specific types of failure, while their ability to provide trustful lifetime prediction is discussed.

. In the injection moulding process, the melted plastic is injected in a mould, which gives the desired form to the PVC fitting, and after cooling the product is ejected.


For pvc pipework in Europe, lead has been used until the early 2000s, when it was replaced by calcium-based stabilisers in most countries (Anders, 2014).

Every step within the production of PVC pipes and furniture PVC fittings can have an effect on the long-term performance of the final product.
