SGS – Composite PE + steel spiraled pipes for non-pressure networks

BRIEF DESCRIPTION

Structured wall pipes made through spiral winding technology that consist of composite profiles of PE and steel. They find application in non-pressure underground sewerage and drainage systems and road embankment crossing. The profiles consists of a smooth inner wall for water flowing, a middle steel section, all coated by a smooth outer surface of PE. All pipe lengths are provided with an integrated junction socket and the respective smooth spigot for the electrofusion or with grooves for the sealing gasket junction system. The diameters range (DN/ID) goes from 800 up to 2000 mm.

Pipe deflection = 3% 415 620 830
Pipe deflection = 5% 325 485 645
Pipe deflection = 8% 215 325 430

The assembly method used to put together the inner and outer PE walls and the middle steel profile is mechanical (not chemical from adhesive substances).

MAIN FEATURES

Wide range of diameters
Flat outer surface
PE and steel profiles are putted together using a mechanical assembly method (no use of chemical tackifiers)
Socket connections with electrofusion technology or with sealing gasket
High reliability of connections tightness
Lightweight and easy to install
High chemical and abrasion resistance
Inert to stray currents
