Megapress S press connectorsAll Megapress S press connectors are fitted with FKM sealing elements. In the dimensions of ⅜ to 2 inches, the press connectors include a round seal-ing element and a reinforced separator ring.The XL press connectors in the dimensions 2½, 3 and 4 inches are equipped with round sealing elements with an increased cord thickness. Given their design, the Megapress S press connectors have the same sealing properties as the Megapress press connectors and therefore do not require a profile. All Megapress S press connectors are labelled with a white dot. In addition, the imprint "FKM" refers to the installed sealing element.

Press connectors – leaking when unpressedAll Megapress/Megapress S press connectors are leaking when not pressed.The "leaking when not pressed" function is clearly marked by a black dot at the bead.

Viega guarantees that accidentally unpressed connections become 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 the dry leakage test in the pressure range from 22 hPa–0.3 MPa (22 mbar–3.0 bar)

Fig. 11: Unpressed press connection (2½–4 inches)

The Megapress sliding couplings have no internal limit stop. For this reason, they are used mostly for repairing defective pipeline sections or for system extensions – e.g. for installing T-pieces in narrow spaces.

Megapress / Megapress S press-in branch connectorThe Megapress press-in branch connectors (with EPDM or FKM sealing elements) can be used to make connections subsequently in unpressurised steel pipe installations (1½, 2, 2½, 3, 4, 5 and 6 inch).By means of the respective tool set, a hole is drilled in the steel piping, and the Megapress press-in branch connector is then pressed in. This makes it possible for example to mount a thermometer quickly and without labour-in-tensive preparations to an existing steel pipe installation. The system will be operational immediately afterwards.

Making a threaded connection in just four steps

Fig. 17: A special drilling device for guiding the drilling shaft is fastened to the steel pipe (1½ to 6 inches) by means of ring or fork spanner.

Fig. 18: The hole is drilled by means of a commercially available drilling machi-ne. The steel chips can be extracted by means of the vacuum cleaner nozzle. Af-terwards, remove the drilling device again.

Fig. 19: Press the press-in branch con-nector to the steel pipe by means of the press machine and the positioning aid. This is a fast and clean way of making the connection to the pipeline.

■ pipe cutter ■ fine-toothed saw ■ chopsaw – low cutting speed ■ angle-grinder

After cutting, deburr the inside and outside of the pipes.

Preparing the pipe ends for the press connectionThe Megapress system is suitable for use with black, galvanised, industrially painted, or powder-coated steel pipes.As a precondition for making technically faultless press connections, the pipes must be free of damage and deformations and the pipe ends must be sufficiently smooth and clean, as well as free of loose dirt and rust particles.

Cutting steel pipes to length

Requirement of smooth, clean, and non-deformed pipe surfaces


20

Requirements in pipe ends ■ Correctly cut to length ■ Inside and outside of pipe wall free of burrs ■ Cross section round, without deformations, e.g. caused by vices ■ The minimum distance to welding seams and bending points must be 3 x D – however at least 100 mm

■ For the installation of Megapress press connectors, the maximum exter-nal diameter of the installation pipe (incl. coating) according to Tab. 6 to Tab. 9 and Tab. 14 must not be exceeded.

■ For the installation of Megapress press connectors, the minimum exter-nal diameter of the installation pipe must not fall below the value speci-fied in Tab. 6 to Tab. 9 and Tab. 14.

Requirements in pipe surfaces ■ Smooth and even – without damage from vices or thread cutters or similar ■ If the pipe has an industrially applied coating, the coating must not be damaged when cutting the pipe (e.g. pipe cutter). Damaged or scratched coating must be previously removed in the area of the insertion depth.

■ Free of grease and oil ■ Free of loose dirt and rust particles and unevenly (manually) applied coats ■ For the Megapress press-in branch connector, the thickness of the coat on the installation pipe must not exceed 300 µm for industrially painted pipes.

NOTE!Do not press on embossed pipe markings.


21

ExamplesAs long as they are free from dirt, smooth, firm, even and undamaged, the following pipe surfaces are suitable for the production of press connections without further treatment:1. Black pipes2. Galvanised pipes3. Industrially painted / powder-coated pipes

Fig. 23: Black, uncoated Fig. 24: Galvanised

Fig. 25: Powder-coated


22

Before making the press connections, pipe surfaces must be treated around the press connections (Fig. 26 and Fig. 27) if they exhibit the following char-acteristics:

■ Unevenly applied layers of paint (Fig. 26) ■ Excessive coat thickness on the pipe (mounting without force not possi-ble any more), max. external diameter according to Tab. 6 to Tab. 9 and Tab. 14 exceeded

■ Bumps, damage, grooves, corrosion or loose adhesions (Fig. 27)

Fig. 26: Uneven, painted Fig. 27: Corroded

■ Do not press on embossed pipe markings (Fig. 28)

23

The following are examples of suitable tools for the work: ■ Wire brush (Fig. 29) ■ Cleaning fleece/sanding paper (Fig. 30) ■ Angle grinder with serrated washer (Fig. 31)

Fig. 29: Wire brush treatment Fig. 30: Cleaning fleece/sanding paper treatment

Fig. 31: Angle grinder treatment Fig. 32: Treated pipe surface

After the treatment, the quality of the pipe surface should be as shown in Fig. 32.The external diameter of the installation pipe must not fall below the minimum value specified in Tab. 6 to Tab. 9 and in Tab. 14.


24

Corrosion protection/coatIn systems where complete corrosion protection is required (e.g. cooling sys-tems), parts of the processed pipe surface that are uncovered after pressing must subsequently have suitable corrosion protection applied.

Pipe fastenerThe general rules of fixing technology apply, e.g.

■ No further pipelines must be attached to existing pipeline installations. ■ Use of pipe hooks is not permitted. ■ Consider the thermal expansion – plan for fixed and gliding points.

25

CommissioningA pressure test must be carried out before commissioning the system, the results thereof must be documented.Procedure:

■ Completely fill the system with the test medium, such as inert gases / filtered potable water. If the system is not put into operation immedia-tely after the pressure test, carry out a pressure test with oil-free com-pressed air/inert gases.

■ Perform the pressure test according to the generally recognised rules of engineering – in sprinkler systems note VdS CEA 4001, section 17.

■ Document the results of the pressure test in a log. ■ Have an authorized expert sign the log and provide it to the customer.
