Viega system solutions fulfil all technical requirements for professional solutions and materials for drinking water installation, consequently offering a maximum of security.
Materials, production and quality control
Viega only uses materials suitable for use with drinking water such as stainless steel, copper and copper alloys. All organic materials for seals and pipes regularly undergo the relevant chemical and microbiological tests.
The surfaces of products, that will come into contact with water later on, are not moistened with water during their quality control tests. This is the only way to prevent microbiological contamination caused by the production process.
Innovative Product Design
Viega press connectors made of copper, gunmetal and stainless steel cause much less flow resistance than other types of plastic or press brass connectors that are available on the market. When using plastic connectors, a solid core is required for all subsequent cavities, which is then extracted again after production. Brass connectors are simply bored at a right angle – quite the opposite of the flow-enhancing water flow conditions from Viega.
Planning, Installation, Commissioning
In our practical seminars, you will find out all there is to known about the latest standards and regulations, the right material selection, pipework, commissioning and operation of drinking water installations. Please contact your local Viega office for more information on seminars.
In the download area, you will find more information, for example, the practical manual, protocols and trade articles, on the subject of drinking water installations and hygiene.
Viega planners and consultants are always available to provide you with professional information and personal support during your planning procedure.
Dry leakage test thanks to Viega SC-Contur
For reasons of hygiene, it is recommended that leakage tests are carried out dry in large buildings. Dry, oil-free air is used or in systems with higher hygienic requirements (e.g. hospitals) inert gases may be used. The relevant safety regulations should be observed. Dry leak testing is carried out before load testing at a test pressure of 110 mbar. The test period lasts at least 30 minutes at up to 100 litres of piping system capacity and has to be increased by 10 minutes for every additional 100 litres. During this test non-pressed press connectors can be identified. The Viega SC-Contur, which can be found on every Viega press connector, guarantees the identification of non-pressed connections throughout the entire pressure range from 22 mbar to 3 bar.
