The PVC pipe is supplied with a range of bends and joints as standard. One important point is where movement or acoustic joints are crossed by the pipe. Shown under is a typical movement and acoustic joint. Occasionally the PVC routing will be of such a length (ICC Birmingham in excess of 30m), that it is impossible to feed the cables through by hand. For this problem a pulley system can be installed while constructing the routing. The pulley system is invaluable when CPT route passes through floors to a level below and/or above ceilings or under raised floors. The diagram shows a typical pulley system. The galvanised tube is welded to a half round metal plate (as under) and the bolts to another half round metal plate claiming the PVC pipe inside. The hangers are fitted along the corridors etc. to keep cables and the like, safely out of the way. Soffit Mounted Cable Hanger

On occasions where the routing CPT has to be above ceilings or under floors etc., it is obviously impracticable to remove tiles or flooring every time access is required. The PVC ducting system in conjunction with the Cable Passthrough System takes care of these problems and lets you take the easy route. The Fireplug Cable Passthrough System is a bespoke transit system for temporary cables, designed to maintain fire compartmentation and acoustic performance. Today as more complex buildings are being built to a higher specification the Fireplug Cable Passthrough System (CPT) has been individually designed and then tailored to suit particular aspects of the changing demands of today’s specifiers. The CPT is a unit that can be used to allow a service that can be described as temporary, such as a T.V. camera cable, to pass through a wall/floor yet still maintain the integrity of the wall/floor as designated. What is meant by integrity is that in a fire situation, you maintain stability and insulation along with acceptable smoke stopping. These points are also collated into designing a practical and sensibly operated system. The PVC routing system lends itself perfectly to carry beer lines on the same principle as a temporary cable, only this time a beer line is more likely to be permanent. Depending on the size of beer python a PVC routing can be designed to accept more than one. The minimum and maximum radius of the python is taken into account with access hatches built at strategic intervals, as at every bend for example. The python being more rigid than an ordinary cable is pushed along the routing from each access hatch. Below are diagrams of some examples.
