PVC drilling pipes

The drilling system developed by Teraplast contains the tubing pipes and the filtration elements made from PVC-U. Teraplast drilling system with pipes and PVC100 filtration elements is used to tube the pits for water supply and epuisment drilling or piezo pits. The drilling pipe are manufactured through PVC extrusion and are blue – RAL5012. They have a smooth interior and exterior surface and are foreseen with sockets to injure pipe coupling.

Lifetime is rated at least 50 years under the conditions of pressure and temperature as well as commissioning technology.

The drill pipe system is produced in three classes of wall thicknesses: P8 (SDR13,6), P10 (SDR21), P16 (SDR26) corresponding to PN8, PN10 and PN16 pressure ranges.

From the dimensional point of view, the range of diameters of PVC-U pipes for drilling produced by Teraplast is between 90 and 250mm

The main features and advantages of PVC-U pipes and fittings


PVC pipes are part of the flexible pipe category. This feature gives PVC-U pipes (unplasticized PVC) a special mechanical strength, which can transfer to the surrounding soil a large part of the charge exerted on them.


PVC drilling pipes have a high chemical resistance to most aqueous solutions, to the aggressive action of soil, salts and caustic substances or aqueous acid solutions. Thus, PVC-U pipes and fittings can be used for the transport of basic or acidic aqueous solutions, mineral salts, etc. with pH between 2 and 12 and working temperatures of max. 60 ° C


The ways of joining PVC pipes for drilling, either by gluing or threading, ensures a secure tightness of the built system


The low weight of the pipe system components and PVC fittings ensures extremely high manoeuvrability in terms of transport, storage and handling of the elements as well as their installation.
