Sewer pipe, Plastic, 50 mm, New. Corrugated pipe and its features: corrugated pipes and fittings are produced from ø 100-1000mm HDPE raw material. They are produced in various diameters and installed with gasketed joint control. They are easily used in the removal of sewage, domestic and industrial waste; in rainwater discharge and drainage water transport lines. Due to their flexible structure, they are not affected by earthquakes and seismic movements. Corrugated pipes ensure the trouble-free operation of infrastructure systems with a 50-year service life. Compacting the soil during the laying of corrugated pipes extends the life of the system, and filling the soil with backfill material during laying is very important.
