MegaPress

Press connector fittings with connectors manufactured from non-​alloy steel 1.0308 for seamless, welded, galvanized, epoxy resin coated, industrially painted and black steel pipes in accordance with DIN EN 10255 (BS 1387) and DIN EN 10220.

Sealing element:

A cutting ring, a separator ring and an EPDM (polished black) profile sealing element are included in the bead of the press connector. The cutting ring cuts into the pipe during pressing and ensures a force-locked connection.

During insertion of the pipe, and later during the pressing, the separator ring protects the sealing element from damage.

Press connectors:

The press connectors are equipped with the Viega SC-Contur, which is a safety technology approved by Kitemark, and ensures that the connection is guaranteed to be leaking in an unpressed state. In this way, inadvertently unpressed connections are noticed immediately during a leakage test.

The connectors may only be pressed with Viega press machines with constant pressing force (e.g. Pressgun 5, Picco, Pressgun 4E/ 4B).

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).

Viega MegaPress fittings are offered in +200 configurations, including:

• Elbows.

• Couplings.

• Reducers.

• Tees.

• Reducing tees.

• Threaded adapters.

• Unions.

Features and benefits:

• Up to 60% less assembly time in comparison with other conventional connecting methods, such as welding or threaded and groove connections.

• Economical due to high time-saving during installation.

• Fire-proof, as flames and flue gases are not produced with cold press technology.

• Universal use. Presses thick-walled steel pipes, irrespective of whether the pipe is seamless, welded, uncoated, galvanized or resin-varnished.

Applications:

• Closed cooling and heating circuits.

• Industrial and plant engineering.

• Systems for technical gasses (on request).

• Heating water for closed pump hot water heating systems in accordance with VDI 2035 sheet 1 and 2.

• Compressed air (dry) in compliance with the specification of the sealing elements being used, EPDM at oil concentration <25 mg/m³.

• Anti-freeze, cooling brines up to a concentration of 50%.

The system is intended for use in industrial and heating systems and is a replacement for welded and threaded connections in new installations and repairs. It is not suitable for use in drinking water installations. For this reason, pipes and connectors are labelled with a black symbol stating 'not drinking water'.

The piping system must not be used for fuel gases in accordance with DVGW G 260. The connectors may only be pressed with Megapress press rings and jaws.
