The factors that determine energy efficiency throughout the lifecycle of a pipeline are the type of raw material used, the production process, the finished product and its useful life.
PVC-O pipes have a low energy consumption and lower carbon dioxide production during their manufacturing lifecycles.
The following are the several phases in the lifecycle of pipelines that lead to the PVC-O efficiency and energy saving.
In the production phase, PVC-O pipes are manufactured through conventional extrusion followed by molecular orientation.
The extruded pipe undergoes pressure and temperature variations to affect its polymer molecules and produce inside stretching of the pipe.
This process enhances the physical properties of the pipe by forming an additional lamellar structure on the pipe wall and keeping its chemical structure.
The pipe strengthens its walls while using less raw material, which leads to the energy savings in the production process.
In the useful life of the pipeline, which begins with the installation of the pipe network, energy efficiency is achieved through design, transport, and performance optimisation.
Due to its lightweight properties, more pipe material can be transported for installation, maximising fuel efficiency and reducing harmful emissions.
PVC-O pipeline installation is cost-efficient and does mot erequire special equipment. Thanks to efficient socket design the assembly is relatively easy to perform.
The optimisation of wall-thickness and the increased strength resulted from the extrusion and molecular manipulation process increases the hydraulic capacity of the PVC-O pipeline.
The capacity depends on the diameter and material width of the pipe.
The above means more fluid can be transported and pumped into the system for the same energy consumption.
Smoother inner pipe surfaces minimise pressure losses and increase speed, allowing fluid to flow faster.
In the final disposal phase after its useful lifecycle, the PVC material can be recycled and reused in the manufacturing of other plastic applications, e.g., gutters or cable sheathing.
Although the PVC-O manufacturing process itself does not permit the use of recycled materials, due to high technical requirements, a comprehensive recycling management process reduces the consumption of raw materials and the volume of waste generated.
