Installation of fixed points and sliding elements.

With the fischer fixed points and sliding elements, planners and installers effectively prevent pipe systems from being damaged by temperature fluctuations. Different designs cover different loads and structural conditions. Significant movements can occur due to thermal expansion of hot lines or contraction of cold lines. The correct use of fixed points and sliding elements effectively prevents damage to the cable attachment and the structure. The design of large-scale installations with high loads is also possible through product solutions for the different load levels. .

Typical process flow for the installation of fixed points and sliding elements

The installation of sliding elements and fixed points for pipelines with thermal expansion is usually carried out in such a way that, after the design of the fixed point positions, the pipelines are first fastened to the substrate or to rail structures with sliding elements. The fixed points are then set at the intended positions of the laid pipeline.

1st stage: Determination of the loads to be lifted

In addition to the axial load due to pipe expansion, the weight load of the pipeline including water filling and selected heat/cold insulation is decisive. Depending on the dimensions and material of the pipes, the loads vary.

Second stage: Calculation and selection of fixed points and sliding elements

A calculation tool is used to determine the loads and the distances between the fixed points. The basis is also the load-oriented preselection of the sliding elements, which must then also be confirmed by the resulting displacement of the pipeline.

3rd step: Installation of the fixing solution with fixed points and sliding elements

The sliding elements are mounted either centrally with one attachment point or with 2 attachment points. The mounting of the metric threads must be taken into account. The anchor points are usually attached directly to the ground.
