PVC BOREHOLE PIPE

 Resistant and Reliable for all boreholes

Forage

DESCRIPTION

SOTICI U-PVC Borehole pipes are supplied in blue color according to DIN 4925 standard. Pipes are manufactured with selected PVC compounds to provide absolute non corrosive pipes with excellent mechanical properties. They are delivered threaded male/female at their ends. Screen pipes are slotted along its circumference with different slot dimensions. Lengths of casing and screen pipes have to be specified upon customer’s request .

ADVANTAGES
  • Corrosion : Chemical inertness of casings and screens makes them insensitive to all forms of corosion .
  • Mechanical resistance : Excellent resistance to very high collapsing pressure, and high tensile strengths of screw joints due to its tranpezoidal threaded structure. Also, new threads for high thickness wall gives a huge strengths for deepest boreholes.
  • Mechanical resistance : Two ategories of casings & screens (normal and reinforced). Mechanical strength and stiffness of the tube accomodate practical loads that arise during installations and caused by soil pressures.
  • Slots of walls screens : The perpendicular disposition of the slots provides higher resistance to collapsing pressure (as compared to casings) and excellent hydraulic properties. Slot permeability adapted to the request flow rate.
  • Food Grade : Boreholes pipes are food grade and hydraulic qualities are preferred over another type of material.

APPLICATIONS

  • • Provisional casings for borehole
  • Definite casings & screens for borehole for depths ranging from 30m to 400m.

JOINTING SYSTEMS 

Two standard thread systems are available:

  • Thread: One socket female end Trapezoidal threads / “Artilleur” threads 
    Standard pipe range with standard wall thickness.
  • FM Thread: Flush joint internally & externally (male/female) Trapezoidal threads / “Artilleur” threads

Thick walled pipe range.

SLOT OF SCREENS

Les  Slots are cut by means of circular saws and arranged transversally to the pipe axis (4 or 6 slots per circumference). Slot widths available : 2.0 – 1.2 – 1.0 – 0.8 – 0.75 – 0.6 – 0.5 – 0.3 mm. For other requested widths, kindly consult us)
