Al-Watani Polycon pipes for trenchless construction are manufactured in a full range of sizes to suit the most diverse range of applications from DN200 to DN2000 in 2m and 3m construction lengths.

The pipe joint consists of a mounted collar integrated into the pipe-wall made of GRP or stainless steel.

Polycon Jacking pipes are manufactured to a specific tested wall thickness which have been proven to be adequate to withstand the axial stresses of jacking. In special circumstances jacking pipes can be manufactured with thicker walls to withstand higher compressive forces.

 Joints used for jacking pipes comprise of a mounted collar (GRP sleeve) pre-assembled at the trailing end of the pipe. An elastomeric sealing ring is positioned before inserting the sleeve. The degree of compression of the rubber ring provides water-tightness to the joint.
