Ducting

Our ducting piping options include standard coiled flexi duct for use in the installation of various buried services, BT duct for telecoms, smooth bore electrical Polyduct, twin wall ducting and rigid PVC duct.

All of our systems come with a variety of fittings and accessories, including standard duct access chambers and the BT quad box chamber system.

Drawcords and accessories can also be found in this section.

Whenever pipes or cables are buried in the ground they should be laid in a duct. Loose couplers are available should there be a need to join coils together, although each coil is fitted with its own integral coupling. PVC rigid duct (lengths as opposed to coils) come with a moulded socket on one end for joining lengths together. Twin wall ducting is plain-ended, although loose joiners are available for creating longer runs.

PURPOSE

PVC Ducting has two uses; it protects cables and pipe ducting in the ground from damage due to earth settlement, and it alerts future contractors and property owners to the presence of the cable or pipe in the ground.

COILED OR RIGID DUCT?

As there is a wide choice of plastic ducting methods, Rigid Duct is generally used when the distance is smaller, or in the case of our rigid twin wall ducts when extra strength is required. Short runs of cable or pipe are usually made using a rigid PVC BT Duct, whereas longer runs are usually run in the flexi ducting as these are quicker to lay insitu (most commonly blue for water supplies and black for electrics).

WHICH SIZE?

This really depends on the material that is being installed in the duct. Our most popular seller is the 63mm black flexi ducting coil, generally used for ducting small amounts of cable for extensions and garden work. Water main installations usually run inside the 110mm blue coil, and commercial electrical installations and solar cabling usually run in a 110mm black flexi duct.

DUCTING COLOUR OPTIONS

The most common colour is black, which denotes that the duct is general-purpose electrical. The colour codes are universal throughout the UK. At Drainage Sales, we sell Ducting Systems for the following uses.

  • General Purpose Electric cabling (Black)
  • Water supply (Blue)
  • Gas (Yellow) 
  • Traffic signals (Orange)
  • Telecoms (Grey)

We are also able to supply BT ducting systems for cable TV, High Voltage Electrics and Street Lighting.
