PE PIPES FOR SEWERAGE

USAGE AND DESCRIPTION

With the constant increase of production as well as consumption of human resources, the world is facing a huge problem - where and how to discharge wastewater. This is particularly true nowadays, when the world is working hard to maintain clean environment. It has been shown that in order to achieve this, the watertight ducts are indispensable for the local or regional treatment plants. In the manufacturing of sewer pipes and fitting elements, as required by modern techniques in order to provide economical, simple and secure solutions, the use of polyethylene is irreplaceable. Pipes made of polyethylene meet all those requirements. Their use in sewer wastewater in industrial sewers (aggressive sewage), in renovating old existing sewerage network in urban centres and, of course, in renovating of dirt saturated lakes is absolutely reliable. The watertight drainage is also needed in the construction of individual houses or commercial
buildings in villages and towns. In many cases the drinking water is still pumped from wells and the sewage, which is not waterproof, and poses a major risk for the population.

ADDITIONAL ADVANTAGES OF PE PIPES:

  • available in rolls and bars of 12 meters or longer,
  • low weight,
  • easy and quick to install,
  • large flow capacity
  • chemical resistance,
  • cheap and easy transportation,
  • multi-purpose technique effluents.

TECHNICAL INFORMATION

The necessary wall thickness of the pipe in the sewer pipes without the pressure is determined depending on the external load, e.g. earth pressure and traffic. Since the plastic materials tend to creep, the deformation increases with time.
There are two types of deformation: short-term and long-term deformation. Polyethylene pipes must be dimensioned in such a way that after 50 years the longterm deformation shall not be more than 6 %. Calculation of polyethylene pipes without pressure, which are laid in the ground, is carried out according to ATV - Worksheet A 127: Guidelines for the calculation of static channels and drainage lines.
