ESENCOR, the copper tube of the third millennium.


The ideal choice for supplying drinking water, for heating plants and for the distribution of gases and combustible liquids.

Manufactured with the most modern technologies available on today's world market, the result of scientific studies and tests that guarantee a considerably lower level of residual carbon than is required by the European manufacturing standard EN 1057, it is an excellent product against corrosion caused by the characteristics of waters present in water beds and in the public water mains.

It complies with D.P.R. 1095/68 and  D.M. n. 174 of 06.04.2004 of Italian Department of Health - ref. European Council Directive n. 98/83/EC  and is therefore suitable to be used in building plants for transporting drinking water to residential buildings.

EN 1057 is the European reference standard at continental level for the manufacture of copper gas and water tubes in water and heating applications. It establishes characteristics in terms of chemical composition, mechanical properties, dimensions and tolerances and the tests that must be carried out during production in order to manufacature a product that complies with specifications.

Sampling plans during  manufacture are applied according to the provisions of standard EN 1057 and guarantee the product's conformity on the basis of tests performed by the internal and independent laboratory that is part of the Corporate Quality System certified according to EN ISO 9001:2000.
