PVC-ABDI Screens-Casings

The water pressure-tight PVC-construction material is specially suited for ground water measuring points. PVC-ABDI pipes for well constructions have proved themselves in practice by corrosion resistance, easy handling, low weight and high stability. This special pipe is characterised by the following features: Absolute leak-tightness of the threaded connection (as certified by the Materialprüfanstalt (official Material Testing Laboratory) Hanover, Test Certificate No. 837.690 dated 22 May 1987, and Test Certificate issued by Leichtweiss-Institute Braunschweig (Brunswick) dated 11 May 1990. Safe assembly of structural part lengths by just one single connection with integrated, non-shifting O-rings. Due to the small external diameter of the bevelled socket, a hanging-up of clay balls or gravel is excluded to a large extent. The elongated socket encloses the external thread, centers and protects it completely.
