Mass concrete pipes

DESCRIPTION AND USES

The HM mass concrete pipes by PREFABRICADOS ALBERDI S.A. is intended, principally, for underground pipelines, black water or wastewater, road drainage, rainwater and surface water by gravity or, occasionally, pressurised. They are manufactured by radial compression and, due to their shape, they are defined as “bell and spigot” type pipes.

At the same time, the European Directive 89/106/CE of Royal Decree 1630/1192 establishes that reinforced concrete pipes must have the CE marking complying with the provisions of the current standard in force, UNE EN 1916:2003. This is why at PREFABRICADOS ALBERDI S.A. we mark all our pipes accordingly.

QUALITY CONTROL OF THE MASS CONCRETE PIPING

• Tightness test using the air leakage test on 100% of the pipes manufactured the previous day.
• If the pipes are manufactured in batches for a particular client order (subject to a surcharge), in addition to the aforementioned test, the following quality control will be performed:
  • Compression resistance of specimens of fresh concrete
  • Analysis of the consistency of fresh concrete
  • Alkalinity and water absorption
  • Mechanical resistance: breakage test of the three edges
  • Hydrostatic tests
  • Tightness tests on the gasket
