properties and a low carbon footprint for the transport of pressurised water.” Molecor produces PVC-O pipes up to DN- 1200mm with pressure classes ranging from 12.5 to 25 bar, and also offers a range of PVC-O fittings. Separately, the company recently installed 22km
of PVC-O pipe at a mining project in Serbia. The pipe, which is up to 1,000mm in diameter, forms part of a treatment plant that pumps away surface water. Molecor says the pipe was chosen due to its high installation performance – even when the terrain and water table slow down the work – and its superior corrosion resistance. Several sizes of pipe were installed in the mine

high-pressure water supply, has signed an agree- ment with Corys Piping Systems. “We are delighted to be able to offer our customers a product that is sustainable and environmentally friendly across its lifecycle, from production through to installation, use and even beyond to recycling and re-use,” said Maged Makar, general manager for Oman, and regional director of new business development at Corys Piping Systems. Maged said that the technology offers signifi- cant advantages in terms of hydraulic efficiencies, long-term performance and total installed cost savings – thanks to its push fit installation technique and lightweight structure. Ignacio Muñoz, CEO of Molecor, added: “With
this agreement, Molecor will be able to provide customers in the Gulf area with our PVC-O pipes – which have excellent physical and mechanical
in Kolubara, Serbia. For instance, removing excess volumes of drainage water was achieved with a line in DN1000 mm. Around half of the installed pipe was 315mm diameter pipe, with a pressure rating of 12.5 bar.
PA testing Several speakers at last year’s PPXX conference also addressed different aspects of pressure pipe. James Mason, of US-based consultancy Mason
Materials Development, explained details of a project to determine the effects of liquid hydrocar- bons on the long-term creep properties of polyam- ide 12 pipe. These effects are an important consideration when designing pressure pipe for the oil and gas industry. It has been well-studied for polyethylene pipe grades, but not for polyamides. “Since PA12 pressure pipe has become ap-
proved for use in natural gas distribution pipelines, interest in its use in liquid hydrocarbon service for
