Intended use
INFO!
The press connector system is suitable for the construction of potable water installations in accordance with applicable guidelines, taking into account the selection of materials in accordance with applicable guidelines and in accordance with the assessment basis for materials in contact with potable water of the Federal Environment Agency (UBA), see Regulations from section: Application areas . For use in other areas of application and in case of doubt over the correct material selection, contact Viega.
Areas of application
The Smartloop Inliner technology is employed as an internal circulation pipe in potable water installations. The system is particularly suitable for hot water pipes in the sizes d28, d32 and d35.
The general rules of engineering must be observed for planning, execution, operation and maintenance potable water installations, see Regulations from section: Application areas .
Viega recommends using the planning software Viega Viptool when dimensioning a potable water installation with Smartloop Inliner technology.
Media
The system is suitable for the following media:
Potable water
max. chloride concentration 250 mg/l (in acc. with PWO)
Product description
The Smartloop inliner technology can be used for potable water installations in accordance with applicable directives, see Regulations from section: Product description .
The plastic components correspond to the applicable regulations, see Regulations from section: Product description .
Overview
The Smartloop system consists of the following components:
Smartloop connection set (model 2276.1)
Smartloop pipe (model 2007.3)
Smartloop tension coupling (model 2276.9)
Smartloop repair coupling (model 2276.8)
The system components are available in the following dimensions:
End closing piece/connecting piece d = 28, 35, 28 / 35
Smartloop pipe d12

- 2 - Adapter
- 3 - Connecting piece
- 4 - Press sleeve
- 5 - End closing piece
- 1 - Tension head
- 2 - Support sleeve
- 1 - Press sleeve
- 2 - Repair coupling
- 3 - Press sleeve
Operating mode
- 1 End closing piece
- 2 Hot water storey connection pipe
- 3 Internally positioned circulation pipe
- 4 Hot water pipe
- 5 Hot water supply pipe
- 6 Connecting piece
- 7 Circulation collector line
Circulation in the hot water leg is achieved as follows: The hot water is connected to the hot water manifold (5). The hot water flows in the hot water pipe (4) to the storey connection pipes (2). The opening in the end closing piece (1), which is installed in the last T-piece of the storey connection pipe (2), ensures that the hot water flows through the internal circulation pipe (3) and thus circulates via the circulation collecting pipe. The temperature of the return flow water is higher than with conventional circulation systems, which, in turn, has advantages in terms of energy.
Compatible components
The model is equipped with press connections and compatible with the following systems:
Profipress
Sanpress
Sanpress Inox
Raxofix
Pipes
The press connections are tested and approved according to the applicable regulations with the following pipe types, see also Regulations from section: Compatible components :
Copper pipes
Stainless steel pipes (material 1.4401 / 1.4521)
Multi-layer pipes

INFO!
The sealing materials of the press connector system are subject to thermal ageing, which depends on the media temperature and the service life. The higher the media temperature, the faster the thermal ageing of the sealing material progresses. In the case of special operating conditions such as industrial heat recovery systems, it is necessary to compare the specifications of the equipment manufacturer with the specifications of the press connector system.
Before using the press connector system outside the described areas of application or if in doubt about the correct material selection, please contact Viega.
