Shrinking of thick-walled heat-shrinkable pipes on already standing poles
Now we suggest how to properly shrink thick-walled heat-shrinkable pipes on already standing poles (renovation). Installation of the Radpol heat shrink set is quick and easy. To do this, apply insulation to the base.
Heat shrink fittings are shrunk by means of hot air blowers, propane-butane gas burners (mild yellow flame) or other heat sources to help warm up the device after a higher temperature of +120°C.
- Disassemble the pole elements, e.g. lighting fixtures protecting the heat-shrinkable tubes.
- Clean and prime the exposed post position.

1. Select a pipe with the required insulation and sound parameters.
- Slide the pipe over the insulated surface.
- Set the blower or flame temperature between +120°C and +200°C. The shrinking temperature should not exceed +200°C, because the material from which the heat shrinkable tube is made may overheat.
- Start shrinking from the bottom of the tube. Heat the pipe all around, trying to get even shrinkage. The lower part of the pipe must shrink and adhere tightly to the surface of the pole.
- Shrink the tube from bottom to top. Heat the pipe evenly, all the time moving the heat source over its surface, so as not to cause local overheating. A properly shrunk tube should be smooth, without bulges or notches.
- If the tube is covered with glue on the inside, the glue should run out of both ends of the tube after shrinking.
- Allow the insulated pole to cool down completely.
