High density polyethylene pipes
FIMAP 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.
FIMAP smooth black surfaced polyethylene pipes conform to UNI EN 12201 and are non-toxic in accordance with national directives issued by the Ministry of Health.
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. garantendo a parità di diametro una maggiore portata d’acqua rispetto ai tubi in ferro.
- greater crack propagation resistance (pipe resistance).
- greater Notch Test resistance (pipe resistance) cut according to internal pressure requirements.

FIMAP drainage pipes can have different slot distribution. In particular FIMAP offers:
- slots at 90° – 270° on casing
- slots at 180° – 180° on casing
- slots at 240° – 120° on casing
- slots at 360° evenly distributed slots
More or less slots can be distributed along the circumference according to the diameter of the pipe required. Pipes can be provided covered in geotextiles.
