Electrogalvanised Conduit System

Product catalog summary

Overview

This document provides technical specifications and standards for electrogalvanized steel conduit systems designed for electrical cables and wires, offering high protection and compliance with European norms.

Specifications

Material: Electrogalvanized steel with special inner paint.
Dimensions: Outside diameters ranging from 16 mm to 63 mm with corresponding inside diameters and bar lengths.
Bar Lengths and Packaging: Bars come in lengths of 3 meters, with quantities per pallet and load varying by diameter (e.g., 16 mm diameter bars: 510 meters per pallet).
Resistance: Compression resistance up to 4000 N.
Temperature Range: Minimum temperatures from +5°C down to -45°C depending on classification; maximum temperatures up to 400°C for certain classes.
Flame Retardant: Pipes are flame-retardant and welded along their entire length to ensure tightness.
Ageing and Environmental Resistance: Insensitive to ageing and yard constraints.

Classification and Standards

Classification codes follow NF EN 61386-2-2, with four-figure codes indicating installation type and resistance levels.
Compliance with European standards NF EN 61386-2-1 and NF EN 60423.
Steel pipe classification: MRL 5557.
