GEROthen® connection pipesSmooth-ended, black – pipes

GEROthen® pressure pipes made from PE100-RC or PE100-RT-RC for horizontal connection of GEROtherm® geothermal probes.

Advantages:


  • Low density compared to other materials
  • Long life
  • Good chemical resistance
  • Extreme toughness and elongation at break
  • Low abrasion


A comprehensive range of accessories (smooth-ended/­collared moulded parts, weld fittings, flanges, tools, machines) rounds off our delivery range.

Product details PE100-RT-RC

Material:


  • Polyethylene PE100-RT-RC* (RT = raised temperature; RC = resistance to crack)


Lieferform:


  • 5 m pipes


APPLICATIONS:


  • Temperature range: –30°C/­+95°C1)

  • Pressure resistance: PN16 at 20°C/­SDR 11
  • Dimensions: de 40 mm to de 50 mm, other pipe outside diameters are available upon request

1) The expected durability of the material depends on the duration and temperature of use, along with the inside pressure. The load limits are calculated based on the cumulative damage rule (Miner’s rule) as per SN EN ISO 13760. For an object-specific definition, the annual frequency temperature profile and the inside pressure must be provided.

* Protected technology, patent pending (No. 01073/­20).

Pressure losses

Sample calculation:
Connection pipe Ø 40 mm:
  • 3,900 l/­h/­(3 geothermal probes × 3,600) = 0.36 l/­s
  • According to table 22 pressure loss at 0.36 l/­s = 1.0 mbar/­m
  • Two pipes flow + return flow × 6 m × 1.0 mbar/­m = 12.0 mbar‎
