PVC O pipes : an economical & environmental analysis for water companies and pipe manufacturers. The global crisis has brought new challenges to the water industry. Meanwhile investments in water are nearly unavoidable to maintain or increase the living quality; the real situation is that water companies, either publics or private, are as stressed as all other kind of companies in the world. It is so, that the need of water infrastructure is forcing to lower cost products and installation cost, transmitting the pressure on prices on installers and pipe manufacturers. At the same time, worldwide the threat of climate change has pushed many governments to define its policy looking for more ecological, environmental friendly solutions on every activity. It´s really difficult to find solutions that combine better performance, cost reduction and lower CO2 emissions. PVC O pipes are today perhaps the solution that better fits this difficult equation. Astonished increment in mechanical properties enables a less consumption of raw material maintaining the same performance, and this is affecting positively to all the players in the water industry. Less material means less oil consumption, together with a higher flow capacity in the same pipe, and more efficiency for pipe installers. Last generation of PVC O technologies allow simple transformations of standard PVC U lines into PVC O lines, bringing extreme savings for pipe manufacturers, and large benefits for potential pipe customers and end users that will welcome this high class and environmental friendly solution in this global challenging situation.

“Food is the new oil and gas” is a rather bold statement, but everyday more and more people are concerned about food scarcity. Bringing irrigation to not productive lands will change the lives of the community and if it can be done with a cost effective and the most ecofriendly solution, even better. This case study...

Plastic pipes have been utilized in the Australian gas distribution network since the early 1970s. The most common plastic type found in Australia is polyethylene (PE), although nylon is extensively used in New South Wales. Early installation of PE pipe was completed using the first generation high density type PE50...

Last methodologies for fast evaluation of the SCG resistance on polyethylene pipe materials are analyzed in this work and compared with traditional PENT and FNCT tests. Strain Hardening (SH), Crack Round Bar (CRB) and Accelerated Creep Test (ACT) will be good alternatives for evaluating PE100RC resins. Moreover, SH...

The replacement of fossil fuels like natural gas by sustainable gases such as biogas and hydrogen can mitigate global warming. There has been some debate about the impact of sustainable gases on the materials used in the gas grid. An extensive study of the behaviour of PE, PVC, POM and rubber materials was therefore...

Normal High Density Polyethylene (HDPE) is commonly used as the fluid contacting element, or the “inner-liner”, in Reinforced Thermoplastic Pipes (RTP) and steel pipes up to 65 ºC. Through a modification of the HDPE polymer matrix, by adding nanoparticles, the E-modulus can be increased. Research shows that...

One of the most critical points in the design of a material with long term high burst pressure performance is to limit the so called "brittle failure", where slow crack growth propagation mode takes place. Since many years, polypropylene has been produced via cascade processes, where different PP based structures are...
