| Abstrakt: | The transit gas pipeline was built in 1970's. The gas pipeline runs from Ukraine through the southern part of the entire Slovak Republic to Czech Republic and Austria. The transit pipeline is made of 5 lines with dimensions of 1,220 and 1,420 m. In our territory, there are 4 compressor plants. Terrain obstacles such as water courses are mastered by 16 bridgings. Currently the life span of many parts is expiring. In 1998 there were completed diagnostic inspections of all the bridgings performed. Consequently, the first repairs were performed on reconstruction works on the bridgings and transit gas pipeline lines and they are on going currently, as well. Similarly, the load-bearing structures of technological parts at Compressor stations started reporting failures recently. These failures occurred by change of operation regime, especially irregularity start up of machinery and the irregular temperature changes. The submitted article analyses the anchoring block sleeve with sliding holding catches and friction braking block sleeve using the Final element method. Critical places on pipeline and sleeves were inspected whether the load-bearing capacity of material is not exceeded. The tasks were solved by use of the software Ansys. The following elements were used: Solid 178, TARGE 170 and CONTA 174. |
