Preparations are designated for the elimination of minor irregularities following welding and of sharp edges inside pipelines (due to for instance division of steel pipes) built in a part of distribution pipeline next to main gas closing valves. Preparations are used for the trimming of the pipeline surface in particular prior to the use of the device RUP-F2. A steel loading rod provided with a cone stem mill and hexagonal ending for the fixing of a ratchet key used as a drive provided in the loading chamber with seal and de-aeration valve. For better occupational safety, the preparation is equipped with a handle and a pin preventing the removal of the rod from the loading chamber with locking bolts. Normally, the preparations are supplied in the set described below or as may be individually required by the customer. The preparations comply with requirements of CSN EN 1775:2008, art. 8.2.3. as the they are designed so that all works could be executed without any media leak.
