COMPONENTS

1. End fitting mat: Cu DHP (EN 12449 Cu DHP)

2. Fitting mat: AISI 303/304 (EN 10088-1 1.4305/1.4301)

3. Braid mat: AISI 304 (EN 10088-1 1.4301)

4. Flexible pipe mat: AISI 321/316L (EN 10088-1 1.4541/1.4404)

5. Ring mat: AISI 304 (EN 10088-1 1.4301)

NORMAL WORKING CONDITIONS

– Nominal pressure : PN 35 up to diameter 54 and PN 25 from diameter 64

– Temperature : -100°C min + 250°C max

– Fluid : suitable for group 2 according to art. 9 Directive 97/23/EC (P.E.D.)

CONSTRUCTION

Manifacturing in accordance to Directive 97/23 /EC (P.E.D.) requirements. Vibratig vibration absorber is made from stainless steel with copper DHP end fittings. All weldings, included copper/stainless steel, are made by TIG or laser systems.

Being brazing-free, it is possible to braze the end fittings to the pipe system without any overheating risk to the Vibratig itself.

EMPLOY

Vibratig vibration absorber is used to avoid the vibrations induced by the compressor. It also reduces noises and can compensate smaller inner displacments. Furthermore, its unique speciality allows vertical installation too. The possibility of water condensation in the lower side has been eliminated, therefore, no problem even at temperatures below 32°F (0°C).

INSTALLATION

• User must be aware that Vibratig cannot absorb torsional and axial stresses, either in compression and extension.

• Vibratig must be installed in perpendicular to the vibration flow. In certain cases it is necessary to assemble two Vibratig to ensure good performances to fatigue life. Should this be the case, a suitable spring support must be placed to ensure stability (see sketch below).

• Fluid overflow inside Vibratig can set off turbolences and noises that can damage and reduce its fatigue life. If so, it is highly recommended to switch to a bigger Vibratig size..

• The connection between Vibratig and the pipe system is usually made by brazing.

• Vibratig unique special characteristics enable the fitter to perform such operations care-free from any overheating to the Vibratig itself.

• Vibratig test pressure must not exceed the nominal pressure x 1.5.

CORROSION PERFORMANCES

• The materials of which Vibratig is made fully suit the conveyed fluids, therefore no extra thickness is needed.

• Installer needs to pay special attention to protect Vibratig from the environment corrosion factors

DISASSEMBLY

When you need to take down a Vibratig – Cut the Vibratig with a handsaw and not by flame cutting. Make sure all the following steps are followed:

• Drain all fluids from the piping system;

• Clean the inside of the piping sytem;

• Cut the Vibratig with a handsaw and not by flame cutting.

MARKING

According to Directive 97/23/EC (P.E.D.), Vibratig is marked as follows:

Item 001 to 013 : 7577/XXX-PN 35-MM/AA             (XXX = position on the drawing table)

Item 014 to 015 : 7577/XXX-PN 35/LLLL/AA            ( MM = manufacturing month)

Item 016 to 032 : 7577/XXX-PN 25/LLLL/AA            ( AA = manufacturing year)

(LLLL = identification lot number)

Vibratig may be marked in any of the “MARKING” areas in the drawing.

For the American market: UL certification available on request.
