Piezometric steel casing

Fimap Technologies polyethylene pipes and filters are recognized and highly regarded by the majority of operators in the sector as satisfying any requirement made by companies specializing in water wells.

The use of high quality raw materials and rigorous testing during the production phase ensure that sanitation and technical regulations of most industrial countries are conformed with.

In particular, threading and micro-slotting conform to DIN 4925, or to specific customer requiremen.

Polyethylene pipes are distinct in the following respects:

  • resistance to mould corrosion, sea water, dilute acid and alkaline solutions, stray currents.
  • greater shock resistance.
  • improved mechanical characteristics over time.
  • simple connectors.

Operating pressure varies in inverse proportion to temperature.

Piezometric pipes allow problems associated with the study and investigation of contaminated sites and monitoring underground waters to be resolved (piezometric reading of ground water tables.) Fimap Technologies strives to be environmentally friendly and as such proposes products aimed at satisfying any investigative or monitoring requirement.
