The pipes and fittings for closed drainage systems are made of rigid PVC U.

• The connection between them is achieved with a socket coupling and bonding with special adhesive to ensure absolute tightness.
• They are supported by a wide range of fittings.
• Excellent resistance to corrosion.
• They do not oxidize or electrolyze.
• Smooth internal surface which, combined with the chemical inertness of the pipes, prevents deposits and blockages in the piping.
