In Russia, market spiralnovityh pipes made of polyethylene (PE) with a diameter of more than 600 mm (large diameter) is only a stage in its development. The main area of use of these plastic tubes are sewer (Gravity, storm sewer) and drainage systems. So far, the construction of sewerage and drainage systems are used, cast iron, asbestos cement, concrete, reinforced concrete and ceramic tiles. Polyethylene large-diameter pipes with difficulty penetrating the market of sewerage and drainage systems, while in Russia there spiralnovitye pipe. Spiralnovitye pipes made from various grades of polyethylene, PE 80, 63. The main materials are polyethylene grades 63, applied for the technical plumbing. What are the technical and operational characteristics of this type of plastic pipe can hope to conquer the market and sewer drainage systems of large diameter? Spiralnovitaya polyethylene pipe is formed by winding a hollow profile of rectangular cross section, welded between the turns of the extruder (hence the name pipes – spiralnovitaya).

The geometric shape of the profile wall pipe provides a high resistance to deformation, which allows broad in seismically active areas. As a rule, spiralnovitye polyethylene pipes are available in two Class ring stiffness – S4 and S8, where the numbers indicated accordingly stiffness 0.05 and 0.08 kg / cm. This allows you to change the depth of the pipes when they are such an underground installation. Technology of production of plastic pipes spiralnovityh possible to solve the fundamental problem of large-diameter polyethylene pipe, which will in the near future to press the other types of pipes (and some entirely replace) for sewerage and drainage systems – is a significant decrease in the mass of the tube at high rates of ring stiffness. Spiralnovitye polyethylene pipes is much smaller in mass (1 lm) than their counterparts from other types of materials, or of the same materials, but made by other technologies. Such design concept allowed the plastic pipe to make a big breakthrough in the development of sewerage systems market in Russia. After downsizing the pipe not only reduces the time installation, its complexity, but also the cost of the entire system of pipes spiralnovityh in comparison with other types of plastic pipe sewer. All these advantages spiralnovityh polyethylene pipes have resulted in recent years only the growth of market consumption of these products, but also the interest of domestic construction companies who are going to actively promote the use of spiralnovityh pipes.
