In the practice of repair and restoration of plumbing, not working under considerable pressure, sometimes it is necessary to apply the technology of connecting brass pipelines at room temperature. Typical situations are: The place of repair is not easily accessible, and excludes work at elevated temperatures; The slightest release of zinc fumes, possible during hot welding; The connection is performed on surfaces of simple shape, without bending and curvature of brass pipes.

Technology of cold welding of brasses

Effective use of special compositions for cold welding copper alloys. They include epoxy compositions, physical and mechanical properties of which fully take into account all consumer parameters of brass alloys. Supplier Evek GmbH offers to buy brass rolled products of domestic and foreign production at an affordable price in a wide range. We provide delivery of products anywhere in the continent. The price is optimal.

Welding technology

Before application the surfaces that are subject to permanent connection are thoroughly cleaned from traces of dust, dirt, grease and other fats. Degreasing is better carried out with the use of dilute aqueous solutions of acids, observing the usual safety rules for such cases. Next, the cold welding itself is prepared for use. The material should:

• Soften to a plastic state, for which the required volume of the substance is rolled out between slightly water-soaked palms;
• Apply it to the tightly squeezed together end sections of the brass, avoiding gaps;
• Press down firmly, and leave under pressure for the time required for complete polymerization of the composition of cold welding (for brass, this time is from 10 to 30 minutes, depending on ambient temperature).

A sign of polymerization is a change in the original color of the composition. After that, the joined parts may be used for their intended purpose. Cold welding brass ineffective if the pipeline is pumped chemically aggressive media, or water temperatures in the brass tube exceed 60 ° C.
