Megapress S

Press connector with Smart Connect Feature
Inadvertently unpressed connections are noticed immediately during a leakage test.
Viega guarantees the detection of unpressed connections in the following pressure ranges with water, compressed air or inert gases:
min. water pressure: 0.1 MPa / 100 kPa / 1 bar / 14.5 PSI
max. water pressure: 0.65 MPa / 650 kPa / 6.5 bar / 94.3 PSI
min. air pressure: 22 hPa / 2.2 kPa / 22 mbar / 0.3 PSI
max. air pressure: 0.3 MPa / 300 kPa / 3 bar / 43.5 PSI

Sealing elements for press connection
FKM (fluorocarbon rubber), matt black, pre-​assembled

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

Dimensions
D½–4, Size availability in accordance with the national regulations

Tools
The functional safety of Viega press connector systems depends primarily on the faultless condition of the press tools used. The Pressgun-​Press Booster is required for pressing Megapress S XL-​press connectors. Viega press tools have to be regularly maintained by authorised service partners.

Areas of application
Industrial and plant engineering
Local and district heating systems as per AGFW FW 524 (after entry into the building, ≤ DN50)
Closed cooling and heating systems
Compressed air systems
Fire extinguishing and sprinkler systems (the required minimum and maximum wall thickness have to be observed)
Systems for technical gases (request required)

Note
Use of the system for areas of application and media other than those described must be agreed in consultation with Viega. Detailed information concerning applications, limitations and national codes and standards can be found in the product documentation, either printed or on the Viega website.

Note – Standards and approvals
Suitable for steel pipes in accordance with Australian Standards AS 1074 (Light, Medium & Heavy) and US Standard pipes ASTM, A53, ASTM A106B & ASME B36.10M Schedule 5 to Schedule 40. NB: There are two ranges of DN65 (D2½) fittings as Australian Standard pipe has an outside diameter of 76.1 mm and US Standard pipe has an outside diameter of 73.0 mm. DN65 fittings with a model prefix of 42 should only be used with Australian Standard pipe. DN65 fittings with a model prefix of 48 should only be used with US Standard pipe.

Operating conditions
operating temperature -5 °C to +140 °C (23 °F to 284 °F)

The press connector system Megapress S is designed for nominal pressure PN 16.

Materials press connector
Steel 1.0308

Note – Protection against external corrosion
Thanks to a zinc-​nickel coating the press connectors are optimally protected against corrosion – e.g. when condensation forms in cooling systems.
The pipe being used should be protected with suitable corrosion prevention – observe manufacturer's information.
Pipes and pipe connectors should be insulated in the same way in accordance with the general rules of engineering.
