PVC pipe cleaning made easier by Picote
For many years, PVC pipe has been something of a mainstay of underground pipeline networks for a variety of utilities. However, as with all pipes, they do occasionally need cleaning and the generally thinner wall design and stiffer nature of the plastic that makes up PVC has meant that aggressive cleaning, to a much greater extent than is seen in PE pipes, could lead to problems of pipe damage if not fracture.
With these potential problems in mind Finland- based Picote has developed a range of cleaning equipment and accessories that has either been specifically designed to work in PVC or can be adapted to clean PVC without detriment to the pipe.
PICOTE SMART SPIDER
One of these developments is the Picote Smart Spider. The Smart Spider cleans all types of pipes fast and in a highly efficient manner and is even safe to use in PVC pipes. As a unique tool, the Smart Spider is designed specifically for pipes where the invert or other pipe sections are missing. The unit easily navigates around 90° bends and is available for use in pipe diameters of 4 in (100 mm) and 6 in (150 mm) when used with Picote’s Maxi Miller machine to drive the cleaning unit. It is also available for use in 6 in (150 mm) and 8 in (200 mm) diameter pipes when used with the Maxi Power Plus miller machine. For smaller sizes in cast iron, clay or concrete pipes, it is recommended that Picote chains are utilised.
Advantages of the Picote Smart Spider include that it is easily rebuilt when necessary using affordable spare parts. There are even rebuild packages available. As the tip of the cleaning legs will wear with use, these are designed to be easily exchanged after the tip has worn out. It should be noted however that the Spider must always be operated with its spring leader to ensure its flexibility.
The Smart Spider is also easy to use with it being necessary to simply connect it to the miller machine shaft using a sleeve bearing. Once attached and the rotational direction has been checked to ensure it is always clockwise, the Smart Spider is placed inside the pipe by manually rotating the Spider legs. Once in position simply turn on the Maxi Miller to no more than the maximum 1,000 rpm and the cleaning process is started. The highly efficient nature of the cleaning process does mean that it is important to ensure that dust is continuously flushed out of the pipe with water when in use.

benefits of the regular Picote cleaning chains, but without carbide inserts, making them very safe for use inside PVC pipes. The chains are used with the Picote Micro
or Mini Miller machines utilising the ⅓in (8.5 mm) diameter shaft in 2 in (50 mm), 3 in (75 mm) and 4 in (100 mm) diameter pipes. When used with the Midi and Maxi Miller machines with its ½ in (12.7 mm) shaft the chains can be used in 4 in (100 mm) and 6 in (150 mm) diameter pipes.
The different chains are designed for best use in differing circumstances. The Cyclone chain is designed for use in damaged pipes whilst the Original chain is
