plast ic pipes

Industrial double-containment pipe Simona, a system provider of thermoplastic solutions, supplies a comprehensive portfolio of sheets, rods, profiles, welding rods, pipes, fittings, valves and finished parts. materials such as PE, PP and PVDF, making them suitable for use in the chemical industry, semi-conductor production, the pharmaceutical sector, metal treatment or paper and cellulose production. The industrial double- containment pipes can be used for transporting liquid and gaseous substances.

engineering – for example, in the form of butterfly valves or pumps. In addition to its processing capability, weather resistance and impact strength, the material has a wide service temperature range from -40°C to +150°C and an increased level of chemical resistance even in the alkaline range. When selecting a suitable material for a specific application, the level of chemical resistance is a crucial criterion in many cases. Simchem is a comprehensive practical guide on all issues concerning the chemical resistance of Simona materials. It is designed to provide users with important guidance for day-to-day operations, and lists almost 4,000 media and proprietary products. In addition, the database provides valuable information about the numerous materials and the properties of plastics. The fully revised 7 th edition of Simchem was launched earlier this year, and is available for the first time in an online version.

The company’s industrial double- containment pipes – a standardised end-to-end system for the safe transport of aggressive substances – are a result of increasing environmental awareness, the desire for process stability even in the event of an accident, and continuing global growth of the chemical industry. Offering an all-embracing, standardised system, Simona is expanding its presence in the field of plant and equip- ment engineering. Pipes and fittings are produced by the company, whilst valves and leak monitoring systems are sourced from experienced partners. To increase the level of safety in transporting aggressive substances, double-containment piping systems are made of highly corrosion-resistant

Simona is able to provide an extensive range of material combinations for the carrier pipe and containment pipe, always tailored to match the relevant requirements profile. The company also offers a wide range of materials for lining the interior of steel and concrete tanks as well as for thermoplastic and GRP composite structures. Whilst PVC can be glued directly using reaction resins, polyolefins (PE, PP) and fluorinated plastics (PVDF, E-CTFE) require fabrics as an adhesion substrate for interlocking connections. The partially fluorinated high- performance material E-CTFE is also used in chemical tank and equipment The global demand for larger diameter pipes for transport pipelines is growing. Molecor technology claims to have been the first to manufacture PVC-O pipes up to DN 400mm, before stepping forward to DN 500mm, and DN 630mm, paving the way for PVC-O to join the list of the materials to be used when undertaking projects of large diameters. The advantages of this material, its lower cost (both raw material and installation cost), and its performance make it a suitable option for the execution of this type of project. As a result of Molecor’s commitment with R&D, a new project has been developed for even larger diameters and higher pressures. This new system has been engineered in order to meet the new challenges of these large pipes. Molecor’s new equipment will manufacture PVC-O pipes ranging from DN 315mm to DN 800mm (12" to 30")
