Threaded PVC borehole pipes and filters

Fimap Technologies PVC 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.

Fimap Technologies PVC pipes guarantee:

  • resistance to mould corrosion, sea water, dilute acid and alkaline solutions, stray currents.
  • no scaling.
  • long-term effectiveness.
  • msmoother internal walls guarantee greater hydraulic conductivity along the same diameter as compared to iron pipes.
  • simple connectors: male/female threads according to the Customer’s requirement, with the possibility of inserting an O-ring rubber grommet.
  • ease of transport and fitting.
