FIXED SUPPORT FOR GALVANIZED PIPELINES Russian patent published in 2022 - IPC E02D27/46 F16L3/10 F16L3/16 

FIELD: construction industry.

SUBSTANCE: invention relates to the construction industry, more precisely to the installation of water supply systems of buildings, and can be used when laying internal systems of cold and hot water supply or heating, in particular when conducting pipelines through intermediate floors, walls, partitions and other structures of buildings. A fixed support for galvanized water supply pipelines is proposed, installed in the opening of the building structure and consisting of a branch pipe passing through the opening of the building structure and connected to flanges resting on the building structure. The branch pipe is made of stainless steel and the outer diameter of the branch pipe is smaller than the diameter of the opening in the structure of the building. Paronite gaskets are installed between the support surfaces of the flanges and the surface of the building structure, and the connection of the flanges with the branch pipe is made with a gap and is welded with an austenitic seam. The ends of the branch pipe are made with connecting parts for connection to the water supply pipeline.

EFFECT: ensuring an increase in the service life of the pipeline, reducing the cost of work related to the maintenance and repair of pipelines.
