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 riser pipes from d 28.
The general rules of engineering must be observed for planning, execution, operation and maintenance potable water installations, see Regulations from section: Fields of application .
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 DWO)
Product description
The Smartloop inliner technology can be used for potable water installations in accordance with applicable guidelines, 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)
- 1 - End closing piece
- 2 - Press sleeve
- 3 - Adapter
- 4 - Connecting piece
- 5 - Press sleeve
- 1 - Support sleeve
- 2 - Tension head
- 1 - Press sleeve
- 2 - Repair nipple
- 3 - Press sleeve
The system components are available in the following dimensions:
End closing piece/connecting piece d = 28, 35, 28 / 35
Smartloop pipe d = 12
Operating mode
- 1 - End closing piece
- 2 - Floor connection pipeline hot water
- 3 - Internally positioned circulation pipe
- 4 - Hot water riser pipe
- 5 - Hot water supply pipe
- 6 - Connecting piece
- 7 - Circulation collector line
- A–F - Ground to 5th floor
The circulation of hot water in the section is achieved as follows: Water is directed back into the hot water heating system and replaced by hot water via the opening in the end closing piece (1) of the last T-piece (2). This ensures that sufficient hot water is available at perfectly hygienic temperatures at every floor connection line.
The temperature in the riser pipe area does not continually drop in the direction of flow with Smartloop inliner circulation. The lowest temperature in the riser pipe is therefore at the end closing piece, in the area of the diversion in the internal circulation. With large-scale systems with several lines, this leads to an increase in the temperature in the circulation collector pipe. As a result, the temperature of the return flow water is higher than with conventional circulation systems, which, in turn, has advantages in terms of energy.
press connector with SC-Contur
The press connection has a circumferential bead in which the sealing element lies. The connector is deformed upstream and downstream of the bead and permanently connected to the pipe during pressing. The sealing element is not deformed during pressing.
SC‑Contur
Viega press connectors are equipped with the SC‑Contur. The SC‑Contur is a safety technology that is certified by the DVGW and ensures that the connection is guaranteed to be leaky in an unpressed state. In this way, inadvertently unpressed connections are noticed immediately during a leakage test.
Viega guarantees that unpressed connections are visible during a leakage test:
with the wet leakage test in the pressure range from 0.1–0.65 MPa (1.0–6.5 bar)
With dry leakage test in the pressure range from 22 hPa–0.3 MPa (22 mbar–3.0 bar)
Sealing elements
Area of use of the EPDM sealing element
NOTICE!

Information for use
Permitted mixed installations
Generally, components from different piping systems should not be used in the same installation. The different materials may have a detrimental effect on each other e. g. cause corrosion.
Generally, components from the Viega systems Profipress, Sanpress and Sanpress Inox can be used in the Smartloop system.
INFO!
The flow rules must be observed in all mixed installations with different metals.
Should you have any questions on this subject, please contact the Viega Service Center.
Corrosion
Overground pipelines and fittings in rooms do not normally require external corrosion protection.
There are exceptions in the following cases:
Contact with aggressive building materials such as nitrite or materials containing ammonium
in aggressive surroundings
If external corrosion protection is required, observe the pertinent regulation, see Regulations from section: Corrosion .
INFO!
The press connector system is suitable for creating potable water installations in accordance with applicable directives, taking into consideration the material selection in accordance with applicable directives, see Regulations from section: Corrosion . For use in other areas of application and in case of doubt over the correct material selection, contact the Viega Service Center.
The chloride concentration in the medium must not exceed a maximum value of 250 mg/l.
This chloride is not a disinfectant, but in fact pertains to the content in sea and table salt (sodium chloride).
