The GABO speedpipe indoor pipe, type 3526, is a halogen-free plastic pipe, specifically developed for installation in building environments. It is designed for low-loss and secure routing of bundle fibres, micro- and mini-cables in indoor spaces, particularly in ducts, tunnels or other enclosed installation channels. The system is fully tested according to EN 61386-22 in compliance with the EU Low Voltage Directive 2014/35/EU, ensuring adherence to legal safety requirements, installation regulations, and compatibility with fire barriers. The pipes are flame retardant and meet the requirements for halogen-free composition according to EN 60684-2 and low smoke emission according to EN 61034-2, making them particularly suitable for indoor use.

Applications

The speedpipe indoor system is designed for use in buildings, especially in areas requiring high mechanical load resistance, such as ducts or tunnels. The reinforced wall thickness ensures increased mechanical stability and protects the installed cables from external influences. The pipes are suitable for routing cables and fibres in enclosed installation systems, with optimised glide ribs on the inner surface enabling smooth blowing-in.

Functions and Equipment in Detail

The inner surface of the pipe is equipped with optimised glide ribs, ensuring efficient and damage-free blowing-in of bundle fibres, micro- and mini-cables. This design reduces friction and minimises the risk of cable damage during installation. The halogen-free and low-smoke composition of the material ensures minimal smoke development and release of toxic gases in case of fire, enhancing building safety. The flame-retardant property slows fire spread and supports fire alarm and evacuation procedures.

Technology Explained Simply

The pipe is made of a halogen-free plastic specifically developed for indoor use. The wall thickness is reinforced to better withstand mechanical loads, such as pressure or impact. The glide ribs inside reduce friction, allowing cables and fibres to be pulled in with lower force and without damage. Testing according to EN 61386-22 includes fire tests, ensuring the system meets legal safety requirements. Standards EN 60684-2 and EN 61034-2 guarantee that the material does not release harmful halogens and produces only minimal smoke, which is especially important in indoor environments.

Compatibility and Accessories

The speedpipe indoor system is compatible with various accessories that support installation and operation. These include, for example, single pull-through seals (EZA-t) in various diameters, blowing couplings (EBM) and blowing couplings with gas-stop (EBM-GS), enabling secure and tight connections. Identification rings (KmR) are used to identify pipe lines, and end plugs (ES) protect the pipes from contamination. Double socket couplings (DSM) allow connecting multiple pipe sections. These accessories are specifically designed for the speedpipe indoor system and ensure a secure and tight installation.

Installation and Mounting

The pipes are supplied on wooden single-use spools or plastic spools (cardboard), optimised for transport and installation. The spools facilitate unwinding and routing over long distances. Cable blowing is enabled by the glide ribs inside, minimising friction. Pipe sections are connected using special couplings, ensuring a tight and mechanically stable connection. Installation is carried out in accordance with EN 61386-22 and applicable installation regulations.

Operational Advantages

The speedpipe indoor system offers high mechanical stability, making it suitable for use in demanding areas such as ducts or tunnels. The halogen-free and low-smoke composition enhances safety in case of fire. The optimised glide ribs enable smooth and damage-free blowing-in of cables and fibres, reducing installation time and improving installation quality. Testing according to EN 61386-22 and compliance with EN 60684-2 and EN 61034-2 ensure conformity with legal safety and quality requirements.
