Abstract

Reinforced concrete pipe has a thermoplastic inner sheath consisting of extruded plates extending in the lengthwise direction of the pipe, and having T-shaped anchoring pins on their outer faces, the gap between the cross beams of the pins being sufficiently large to allow the penetration of the aggregate in the concrete. The sheath is firmly anchored.
