PVC design and installation user-manual

Engineers and contractors involved in the design and installation of PVC piping systems are now able to benefit from a new manual that has been launched by DPI Plastics, a manufacturer of water reticulation, drainage and pipe-fitting systems. The ‘Design Guidelines for PVC Pressure Pipe Systems’ manual is an updated version of the company’s previous ‘Pressure Manual’, and includes additional information on new PVCO technology, guidelines on solvent cement welding, modifications to references of standards and an introduction to the code of ethics and conduct drawn up by the South African Plastic Pipe Manufacturers Association (SAPPMA), of which the company is a founding member. DPI Plastics technical and product manager for pressure pipe systems, Renier Snyman, pointed out that the manual is provided free-of-charge to all DPI Plastics clients: “The Design Guidelines for PVC Pressure Pipe Systems manual is ideally-suited to design engineers, municipal engineers and contractors installing piping systems, and is available for free in CD format, and online.” Mr Snyman added that the manual serves as a one-stop guide for all the relevant and comprehensive information relating to PVC pipes. “The guidelines in the manual cover the physical properties, design requirements, chemical resistance, correct laying methods and advice on installation, in

showing power consumption, material efficiency and pumping costs for various piping systems so that informed, planet- friendly choices can be made. Mr Snyman commented that the new manual is also more user-friendly: “The previous manual contained up to 30 flow and friction charts, catering to each pipe size. This created a cluttered effect and, as a result, we decided to replace these charts with nomograms containing typical pipe sizes for PVCU, PVCM and PVCO products, making it more user- friendly and easier to understand.”

one concise manuscript that will benefit numerous industry players.”

The 48-page manual serves as a new- and-improved version of DPI Plastics’ previous manual, which was launched in 2000 when PVCM was the product- of-choice in the plastic piping market. Since then, however, PVCO has been introduced to the Southern African market and, as a result, the manual includes detailed information on the new technology. Also added to the manual are sections on ‘green’ issues, which are more important to engineers and desi ners today, compared to a decade ago. The manual includes tables of comparison
