Unique among  the items that Cosmoplast  can offer  is  its 1,200mm  well  casing  and screen products.  These    have   been  configured  for some of the unusual well  requirements,  which are found in the  gulf region. These  sizes  can be produced in solid wall formats utilizing  either single extrusion or multi-layer co-extrusion with the screw jointing  system  employing  an enhanced moulded  thread  design. Cosmoplast   co-extruded  casing   and  screen  products  are   the  vanguard   of   material development   in  wellcasing systems

These  unique  pipes  made from specialized uPVC formulations,  which  provide  high tensile strength coefficients for considerably reduced wall thickness in comparison to normal well casing products.

Similar to the well casing product, the Durawell Screen is made of a specially formulated uPVC compound to provide maximum hoop and axial strength, material stability and total resistance to corrosion or chemical attack. Different water table conditions will dictate the types and specifications of screen to be used to provide efficient and trouble free operations over the longer term. Critical factors such as open area and slot width of the screen will be specified by the size and type of the sand and gravel packing required by either the end user or drilling contractor involved. The Durawell range has been specifically developed to offer a specialized screen configuration for most water well and aquifer conditions encountered.
