PIPELINE SLIDING SUPPORT Russian patent published in 2019 - IPC F16L3/16 E01D19/04 

FIELD: construction.

SUBSTANCE: invention relates to construction of pipelines and can be used for other extended structures, for example, bridges, passages, transport galleries. Sliding support of the pipeline contains lengthwise and crosswise guides, between which there is an anti-friction pad in the form of a tablet, which is made in the form of a cup with a through hole. In the cup there is a compensator made of resilient material having a height less than the height of the cup so that cavities are formed between the upper and lower end faces of the cup and the upper and lower surfaces of the compensator. In said cavities there are antifriction inserts, preferably of fluoroplastic. Placing the antifriction insert in the cavity formed by the surface of the compensator and the walls of the through hole of the cup enables to exclude the adhesive compound of fluoroplastic with the parts of the antifriction pad in the form of a tablet.

EFFECT: possibility of movement of antifriction inserts along the through hole of the shell allows compensating for installation and operational misalignment of the pipeline relative to the construction structure due to the elasticity of the compensator.
