Reinforced concrete piping

DESCRIPTION AND USES

The HM reinforced concrete pipes by PREFABRICADOS ALBERDI S.A. is intended, principally, for underground pipelines, road drainage, black water or sanitation, rainwater and surface water by gravity or, occasionally, pressurised. Given their inner steel reinforcement, they are ideal for bearing considerable loads generated by road traffic or significant coverings of soil.

They can be classified according to their geometric shape and their manufacturing method. On one hand, there are the “bell and spigot” type pipes manufactured by radial compression (hereafter TEC) and “tongue and groove” or “halved joint” type pipes made by vibrocompression (hereafter TEM).

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

• Tightness test using the air leakage test on 100% of the pipes manufactured the previous day (up to Ø1200 included).
• 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
  • Layout of the reinforcement
  • Mechanical resistance: breakage test of the three edges
  • Hydrostatic tests (up to Ø1200 included).
  • Tightness tests on the gasket
