DESCRIPTION OF THE PROBLEM
Connections of 2'' were to be connected with the grate pipes of two ionite exchangers of a new construction (the grate pipe – connections – openwork pipes, all elements made of acid-resistant steel). Due to assembly reasons, the connections could be welded only inside the containers, i.e., after the removal of the grate pipe. Due to the difficult welding position of the material, a limited space, and the threat of welding distortions, as well as the possibility to damage the chemo-resistant covering, the user decided to apply the technology of gluing the connections.

DESCRIPTION OF THE REPAIR
The Connections with openwork pipes inside them were carefully defattened with Chester Fast Cleaner. The openings and areas near the openings of the grate pipe were cleaned, made rough, and defattened. The grate pipe was inserted into the container. Openwork pipes were supported against supports, and the connections were inserted into the openings of the grate pipe. Clamping rings were temporarily fastened and the pipes were leveled with the help of rubber washers. A small quantity of Chester Metal Super was rubbed into the surface of the connections, as well as the openings and areas around them. Then, the material was added so that, after the connections are inserted, the excess flowing out of it allowed us form a weld.

ACHIEVED EFFECTS
The technology of gluing turned out to be much simpler and cheaper than welding. This method of connecting the pipes is very important in modern ionite changers, where a similar system of filtering off of the deposits.
