PVC has been used successfully for sewer and sanitary drainage pipes in Australia for over 40 years. It is the predominant material for these applications. The reason for this success is the superior, all round performance of PVC piping systems compared to the various alternatives. Equally important has been the ability and readiness of the PVC pipe and fittings industry to adopt new technology and design features relevant to the Australian environment, to invest in new production equipment and expand the product range. The use of material efficient pipe constructions and the ability to use the core of PVC sandwich construction pipes as a sink for the recycling of PVC from a variety of sources has led to an enhanced sustainability status of PVC sewer pipe. This, along with other environmental aspects such as low embodied energy, makes PVC the most sustainable material for sewer applications in Australia.

Components made of plastic are facing ever-increasing demands with respect to their production, use and durability. This also holds for gas and drinking water pressure pipes made of high-density polyethylene (PE-HD), where service lifetimes of up to 50 years and in some cases even 100 years are required. One of the...

Maintaining dimensions within specifications is problematic for the extrusion of large diameter thick-wall polyethylene (PE) pipe (> 75 mm wall) due to sag caused by insufficient resin melt strength. However, sag can be controlled through careful resin selection and optimization of the pipe cooling process. This...

The Atlanta Braves Major League Baseball team built a new stadium north of Atlanta, Georgia. The field drainage design required the removal of 75mm (3 inches) of rainfall an hour and a system for warming or cooling the field using air blown through the drainage system and field profile using heat from pipe buried...

In the present paper we introduced how high modulus polypropylene helps an innovative design of utility tunnel up to 4000mm in diameter. High modulus polypropylene shows high modulus but still maintain reasonable flexibility so that tunnel and surrounding soil could form an integrated system, which means no force is...

Large diameter pipe was introduced in refineries and petrochemical plant, desalination plant and power plant for water intake and sea out fall in the past decade. PE100-RC material was selectedfor its excellent balance of superior bi-modal stress crack resistance and consistent high stiffness modulus. Under the...

Through tensile tests, simulated orientation, tribology, and finite element analysis, this study explored the effect of temperature, lubrication and applied hydraulic pressure in the PVC orientation process. It was demonstrated that tight control of these parameters is critical in a continuous PVC orientation process...

The need for larger diameter pipes and fittings for in-house heating, plumbing and domestic water systems is pushing the existing materials and processes to their limits. More often final products cannot be produced without penalties either in production rate or in final product quality. This paper discusses...

The coal seam gas industry in Australia is currently undergoing a major expansion with over 50,000 km or 30,000 mile of PE100 pipes to be installed in diameters ranging from DN110 to DN710. The pipes are being used to carry produced water, gas and treated water. The considerable quantity of pipe to be installed in...

PVC is clearly widely known as a material highly suited for trenched or open-cut pipe installations for a variety of uses. Less widely discussed is the fact that PVC offers the widest range of options for trenchless installations. While open-cut installations continue to be the standard method of construction for new...

Over the past several years, we have conducted extensive investigations of the Rapid Crack Propagation (RCP) behavior of Polyethylene (PE) pipes. While the typical data of interest is the Critical Pressure (Pc) and/or Critical Temperature (Tc), we chose to take our investigations further by exploring and generating...

Dual cooling is a post-extrusion cool down process employed for polyethylene (PE) pipe, whereby either water or ambient air is forced through the pipe bore following extrusion, in order to accelerate cooling. The primary benefits offered by the dual cooling process are increased production rates and reduced resin...

Ipswich Water commenced reviewing the service lives of different pipe materials in its gravity sewer system. Unlike other pipe materials, PVC sewers did not have failure histories, or deterioration revealed in CCTV inspections, even after 25 years of service. Therefore establishing a realistic predicted life was not...

PVC-U and PVC-M pipes may be used in applications where they are subjected to cyclic pressures generated by the operation of pumps and valves. It is therefore important that the pipe material’s response to cyclic loading is quantified and that pipelines are designed and operated within the material’s established...
