Polyethylene reinforced with short glass fibres (PE-sGF) piping systems for industrial applications — Part 1: General

This document specifies the general aspects of short glass fibre reinforced polyethylene (PE-sGF) piping systems, manufactured by the spiral cross winding method, which are used below ground for the conveyance of liquid fluids for the following industrial and agricultural uses:

— chemical plants;

— industrial sewerage engineering;

— power engineering (cooling and general-purpose water supply);

— agricultural production plants;

— water treatment;

— small hydraulic power plants (general-purpose water supply).

In conjunction with the other parts of the ISO 22101 series, this document applies to PE-sGF pipes, fittings and their joints with each other, with other PE-sGF components, and to components from other materials intended for use under the following conditions:

a) allowable operating pressure (PFA) up to and including 25 bar[1];
b) operating temperature of 20 °C as the reference temperature.

NOTE For other operating temperatures, guidance is given in Annex A.

Other application areas differing from those listed in the scope can be permitted if the requirements of this document and/or relevant national requirements are taken into account. Drinking water applications are o
