Pipeline Replacement using Relining
Relining of old pipeline systems is becoming an increasingly attractive option to asset owners and operators as an effective alternative to open trench replacement. Relining options rely predominantly on plastics pipe systems for their success. Relining can take a variety of forms – slip lining, swage lining, pipe cracking, folded and formed are some of the popular options. The major material options are Polyethylene (PE) and Polyvinyl Chloride (PVC) with application to water, sewer and gas pipeline renovation in both pressure and non pressure systems. In some cases the lining utilises strength from the host pipe and in others the new pipeline is completely stand alone.
More details are available in the technical paper.
Standards Technical Committees
A key objective of PIPA is to develop and publish appropriate standards, guidelines and specifications for plastics pipes, fittings, valves and ancillary products. PIPA is on the Council of Standards Australia International and is a nominating body to Standards Australia and New Zealand Technical Commitees. Members contribute to the development of these standards and guidelines.
Commitees on which PIPA members are represented is available in the list.

Pipeline Design Software
This design program enables the user to undertake the structural design of a flexible pipeline in accordance to Australian/New Zealand Standard 2566.1.1998. Available from Iplex Pipelines.
Iplex pipeline design tools can be accessed on the Iplex Website.
-
Iplex Structural Design Tool is a program which enables the user to undertake the structural design of a flexible pipeline.
Hydraulic Flow Calculator is a program which can be used by designers of water supply, sewerage, irrigation or industrial pipelines, and has been made available as an alternative to using Flow Resistance Charts.
Chemical Resistance Guide is for information on chemical resistance properties for Iplex pipe products.
Polyethylene Pipeline Code
Reference can be made to the Codes of Practice produced by WSAA. The code for polyethylene, WSA 01 - 2004, provides a guide for water industry practitioners towards best practice in the use of polyethylene pipeline systems in water and sewer pressure pipelines, non-pressure wastewater reticulation pipelines, pipe relining using polyethylene and requirements for training programs. It also contains several construction drawings specific to polyethylene. PIPA members may obtain a copy through the PIPA office.
A Technical Note (WSA TN1) on squeeze-off of polyethylene pipe is also published to provide additional guidance to maintenance managers responsible for property service connection pipes http://www.wsaa.asn.au/frameset2.html under Projects and National Codes of Practice.
