The RAP pipe transport frames consist of two components. The first of these are plastic segments – spacers that have curved beds corresponding to the diameter of the transported pipe. These segments are placed between the individual layers so that the pipes are fixed in all directions against movement and cannot touch each other. The second components are threaded rods, textile straps, or steel frames, which hold the segments together to form a solid package of pipes of dimensions suitable for international transport. At the same time, these frames are used for lifting the entire bale with a crane and the necessary handling.
The frames are supplied in three versions.
- RAP – segments are vertically pulled together by threaded rods
- ECONO RAP – the segments are vertically pulled together with textile straps
- LE RAP – segments are inserted into massive steel frames
The RAP transport system is manufactured for pipe diameters from 2 2/3 “to 9 5/8”. The diameter of the pipes then corresponds to the maximum number of pipes that can be stored in one package, where it is from 56 pieces of pipes with a diameter of 2 2/3 “to 4 pieces of pipes with a diameter of 9 5/8”.
As this is a lifting device, all transport frames are equipped with the appropriate certification and must be regularly inspected.
