Plastic sewer shafts are appropriate for sewage pipeline networks of various diameters to serve as inspection, straight, continuous, confluence, down-grade types. Their advantage is a variable height of the shaft, height of connecting inlet and outlet piping of various diameter, low weight and easy transportation and installation handling even by low temperature.
Variable system of polyethylene shafts in several types complies to any requirements referred to construction of sewage pipeline systems. All shaft types can be customized to the customers’ needs, including modification of height, diameter, profiles and connection directions. Back valves or other fittings can be installed.
PLASTIC INSPECTION SHAFTS
Plastic inspection shafts present a modern, ecology-friendly and operating cost saving option for heavy, bulky and maintenance demanding concrete structures. Currently, lasting tightness of plastic pipelines and shafts is of great importance due to frequent occurrence of floodings. Excellent chemical resistance makes a reason for an extensive installations of plastic inspection shafts also in aggressive underground water conditions.
- low weight – easy transportation and installation – excellent corrosion resistance, incrusts occurrence – long service life and sustained tightness.
