What is MultiDuc?

MultiDuc is a duct bank system with 4, 6 or 9 way options. Units can be combined to form multiple duct banks for under track crossings. Moulded in structural foam HDPE, MultiDuc is tough and easy to use. A comprehensive system of duct lengths, corners and accessories allows UTX/URX and Bridge Crossings to be formed in narrower trenches than required for duct banks built from several single ways.

The system comprises standard straight conduit sections and a full range of accessories to manage common bends, duct configurations and for interfaces with single duct, vaults and pits.

System Components - Standard Conduit Sections

4, 6, 9 Way units which join with bell (female) and spigot (male) joints to have lay length of 1.065m per unit. Units clip together and offer about 2° flexibility. Each duct way is equivalent to 100mm single pipe.

Benefits

• Strong - narrower trench.
• Fast & easy to assemble.
• Lightweight, safe and easy to handle in the yard and trackside.

About Structural Foam Moulding

All of our MultiDuc components are produced using the 'Structural Foam' moulding process which is similar to injection moulding. However the difference is that inert gas (nitrogen) is used to create a foam inner core within the part's wall while retaining an integral exterior skin. This process gives the following advantages:

• High strength to weight ratio
• High stiffness to weight ratio
• Stress free parts to eliminate warpage
• High Density PolyEthylene (HDPE) provides excellent shemical and physical properties.
• Non-porous surface - will not absorb moisture
• No CFC's used in the process

Accessories

A full range of accessories for each of the 3 sizes:-

• Connector units to convert male to female (spigot to bell). Double bell (female-female) and double spigot (male-male).
• Single Duct Adapters allow break out from conduit to regular single duct.
• Neoprene gaskets allow water/gas resistant systems.
• Flexible Duct Bends to form 90° tight bends
